0:00:02 > 0:00:04- I know about my mother. - I have not been running Elena.
0:00:04 > 0:00:06- Someone is posing as me.- Bullshit.
0:00:07 > 0:00:09We have to deal with Sasha Gavrik.
0:00:09 > 0:00:12- We can't. - Why not?- Because he's my son.
0:00:15 > 0:00:18- To old enemies. - New friends.
0:00:20 > 0:00:22Intelligence-sharing protocols are under review.
0:00:22 > 0:00:25- You want me to investigate a CIA Deputy Director?- He's posing as me.
0:00:25 > 0:00:27Emergency contact. I need to speak to Harry Pearce, right now!
0:00:27 > 0:00:29Tariq!
0:00:56 > 0:01:01'Flight BA8476 is now boarding at gate five.'
0:01:18 > 0:01:19Hold on!
0:01:38 > 0:01:42Some of you know how it feels to lose a valued colleague. Others not.
0:01:42 > 0:01:46Tariq's parents have requested that his funeral be family only.
0:01:46 > 0:01:49We'll have a private memorial service on Friday.
0:01:49 > 0:01:52Then we'll discover why our friend was murdered,
0:01:52 > 0:01:55and then we'll find his killer.
0:01:55 > 0:01:57Yes? What is it?
0:02:48 > 0:02:5250 minutes ago, a routine scan at London Airport
0:02:52 > 0:02:55picked up a trace reading of 200 millisieverts on a baggage cart.
0:02:55 > 0:02:57The 6:30pm flight from Athens.
0:02:57 > 0:03:00That level indicates a small but powerful amount
0:03:00 > 0:03:03of unaccounted-for, unstable radioactive material -
0:03:03 > 0:03:07an 'orphan source'. It was too late to recall the baggage
0:03:07 > 0:03:09or discover which bag it actually was.
0:03:09 > 0:03:11Then we pull in everyone who was on the plane.
0:03:11 > 0:03:15We might not need to. This man was on that flight.
0:03:15 > 0:03:17Passport in the name of Matthew Wilkinson.
0:03:17 > 0:03:21But the photo is John Douglas Grier... 'Johnny'.
0:03:21 > 0:03:23Hard-line anarchist and anti-capitalist.
0:03:23 > 0:03:26Numerous convictions for violent offences.
0:03:26 > 0:03:29He planned a major bombing campaign
0:03:29 > 0:03:32against industrialists in Germany in 2002.
0:03:32 > 0:03:34We think he's been hiding out in Greece
0:03:34 > 0:03:37with what's left of the October Sixteen anarchist terror group.
0:03:37 > 0:03:39- We're thinking dirty bomb? - Yes.
0:03:39 > 0:03:43All government and financial institutions and terror targets have been warned.
0:03:43 > 0:03:45Known affiliations?
0:03:45 > 0:03:49Anarchist pals all over. He's a hero to the new generation.
0:03:49 > 0:03:51Grier's a lone wolf. He's hyper-paranoid,
0:03:51 > 0:03:54very cautious, trusts no-one.
0:03:54 > 0:03:59He's extremely volatile. We need to be careful. Only one weak spot.
0:03:59 > 0:04:03He has a younger sister, Natalie. She's 27.
0:04:03 > 0:04:05Admin assistant at London City Transport.
0:04:05 > 0:04:08We suspect Grier's been sneaking back into the UK
0:04:08 > 0:04:09once a year or so to see her.
0:04:09 > 0:04:13She's our best bet to finding him and the source as soon as possible.
0:04:14 > 0:04:19Any nuclear threat takes automatic precedence. The investigation into Tariq's death will be frozen.
0:04:19 > 0:04:22All resources go into finding Grier.
0:04:26 > 0:04:29So that's it? We're dropping it?
0:04:30 > 0:04:33Officially, we have to. Unofficially, we can't afford to.
0:04:33 > 0:04:38Grier takes priority, but can you work both operations simultaneously?
0:04:38 > 0:04:40Yeah. No worries.
0:04:40 > 0:04:45Then do it. Tariq was trawling CCTV the night he died,
0:04:45 > 0:04:48looking for the people who stole our laptop.
0:04:48 > 0:04:51If that's the reason he was killed, we need to know.
0:04:54 > 0:04:56Forgive me if my mouth is dry, Harry.
0:04:56 > 0:04:59I've just been blowing smoke up the arse of big business.
0:04:59 > 0:05:02So what fresh new hell do you have for me today?
0:05:02 > 0:05:07An anarchist terrorist in possession of nuclear material, whereabouts unknown.
0:05:07 > 0:05:09Do we know what he plans to do with it?
0:05:09 > 0:05:12He has experience with explosives. We're anticipating a dirty bomb.
0:05:12 > 0:05:15'The right location, the correct amount of propellant,'
0:05:15 > 0:05:17a three-mile area could be irradiated.
0:05:17 > 0:05:20One day, you'll bring me some good news.
0:05:20 > 0:05:24I'll convene Cobra. In the meantime, keep me extremely updated.
0:05:30 > 0:05:32A lot of our methods won't work on Grier.
0:05:32 > 0:05:35Going undercover with the sister is our only way in,
0:05:35 > 0:05:38but we have to do it before Johnny makes contact.
0:05:38 > 0:05:41How much does she know about what he's done?
0:05:41 > 0:05:45That's something you'll need to find out. Natalie does internet dating.
0:05:45 > 0:05:48She emailed a friend to say how badly it went last time.
0:05:48 > 0:05:51So we're honey-trapping her? Even though she's innocent.
0:05:51 > 0:05:54Right now, she's our only way of finding John Grier.
0:05:54 > 0:05:57Even if she is innocent, she still might be loyal to him.
0:05:57 > 0:06:02We have to find that radioactive material, so we need to do this now.
0:06:05 > 0:06:07We can't have backup too close.
0:06:07 > 0:06:09If Grier shows, he could spot them.
0:06:09 > 0:06:13- If things turn nasty, you'll be on your own. Do you want a weapon?- No.
0:06:13 > 0:06:15It's just another thing we risk him finding.
0:06:15 > 0:06:19Pre-loaded with your legend, but it also detects radiation.
0:06:19 > 0:06:22The spray's a cobalt solution we can use to track Grier.
0:06:22 > 0:06:26It's not that reliable, but we can't risk using a conventional tracker. He'd find it.
0:06:26 > 0:06:29- Got me a date?- Bumped your profile to the top of her match list.
0:06:29 > 0:06:33She's been gazing at photos of you for the last 40 minutes.
0:06:33 > 0:06:36So, are you free tonight, Ryan?
0:06:49 > 0:06:50Natalie!
0:06:50 > 0:06:51Ryan?
0:06:53 > 0:06:55- Hi.- Hi.
0:06:55 > 0:06:57It said on your profile you liked red,
0:06:57 > 0:06:59so I asked for the reddest one they had.
0:07:00 > 0:07:04I've been sat here for ten minutes. I could have come up with better than that.
0:07:04 > 0:07:06Shall I give you another ten, yeah?
0:07:39 > 0:07:42How about you? You got brothers, sisters?
0:07:42 > 0:07:44Er... No.
0:07:45 > 0:07:47No, it's just me.
0:07:49 > 0:07:52- Another one?- Mmm...
0:07:52 > 0:07:53Or we could, um...
0:07:54 > 0:07:56We could just get one from the offy.
0:07:57 > 0:07:59PHONE RINGS
0:07:59 > 0:08:01Dimitri?
0:08:01 > 0:08:04She's denying that she has a brother.
0:08:04 > 0:08:06But I don't think she's covering for him.
0:08:06 > 0:08:08It's more like she's ashamed.
0:08:08 > 0:08:09You need her trust.
0:08:09 > 0:08:11Just do whatever you can to get close.
0:08:11 > 0:08:13I thought we didn't do that.
0:08:13 > 0:08:16Erin, I'm not comfortable with this.
0:08:16 > 0:08:21Dimitri, men are lying to women all over the world right now to get them into bed. Don't over-think it.
0:08:22 > 0:08:23Understood.
0:08:49 > 0:08:51Thank you.
0:09:00 > 0:09:02So...
0:09:04 > 0:09:05..are you a dancer, Ryan?
0:09:05 > 0:09:08Well, I'm only doing it to put myself through college.
0:09:08 > 0:09:10SHE LAUGHS
0:09:19 > 0:09:21TEXT ALERT
0:09:21 > 0:09:24Don't you want to get that?
0:09:27 > 0:09:30Don't you think we're a bit drunk for that?
0:09:30 > 0:09:32Well, I'm not.
0:09:32 > 0:09:34And if you are...
0:09:36 > 0:09:38...hard luck.
0:09:43 > 0:09:46Ooh, sorry. I need to sit down.
0:09:46 > 0:09:48Too much red wine.
0:10:04 > 0:10:06One of your friends checking up on me?
0:10:09 > 0:10:10SHE TURNS THE MUSIC OFF
0:10:16 > 0:10:18You OK?
0:10:18 > 0:10:20Yeah...
0:10:23 > 0:10:28Look, Ryan, I don't... I don't really know what we're doing here.
0:10:28 > 0:10:31I mean, you don't seem very...
0:10:31 > 0:10:35It's just we're both a little drunk, and I wouldn't want to ruin...
0:10:35 > 0:10:40Yeah. I've heard this one before. I'll get you a cab number.
0:11:00 > 0:11:05HE TURNS THE MUSIC ON
0:11:10 > 0:11:11I got a...
0:11:18 > 0:11:19You've changed your tune...
0:11:19 > 0:11:21Not really.
0:11:21 > 0:11:23You just weren't listening.
0:11:32 > 0:11:36Harry, I'm going home. Was there anything?
0:11:36 > 0:11:39Yes, come in. Close the door.
0:11:40 > 0:11:44Elena's communiques, from whoever's posing as me.
0:11:44 > 0:11:45I need to collect them from her tomorrow,
0:11:45 > 0:11:48but I can't risk being seen with her again.
0:11:48 > 0:11:50And you're the last person I want to ask.
0:11:50 > 0:11:54But you're the only one I can. Believe me, I...
0:11:54 > 0:11:57Don't. It's fine. I'll do it.
0:12:15 > 0:12:17I need your help today.
0:12:17 > 0:12:20I have to meet Harry, to give him the messages I received,
0:12:20 > 0:12:23so he can find out who really wrote them.
0:12:25 > 0:12:28- Why did you do it? - HE SOBS
0:12:28 > 0:12:36- Sasha, what's wrong? Daragoj. - Did you know about the...
0:12:36 > 0:12:41the missing officer? Anatoly...
0:12:41 > 0:12:45He saw you with Harry.
0:12:51 > 0:12:54- He was your friend. - I had to stop him.
0:12:54 > 0:12:58He was going to tell Kuzin. It would have been the end.
0:12:59 > 0:13:02So I need to know why you betrayed us?
0:13:21 > 0:13:27My mother and father, the grandparents you never knew,
0:13:27 > 0:13:31they told me their coffins were closed
0:13:31 > 0:13:35because their car had caught fire.
0:13:38 > 0:13:44Three months before they died, they were photographed in a park,
0:13:44 > 0:13:50talking with some dissidents who were under surveillance.
0:13:50 > 0:13:55My parents didn't die in a car accident.
0:13:55 > 0:13:59They were executed by the KGB.
0:14:04 > 0:14:06Their crime was to ask the wrong person.
0:14:10 > 0:14:16I'm so sorry, Sasha. I am so sorry.
0:15:21 > 0:15:23Morning.
0:15:24 > 0:15:26Morning. Are you Natalie's flatmate?
0:15:26 > 0:15:33No. I'm her brother. And you are?
0:15:33 > 0:15:39I'm Ryan. She said she didn't have any brothers or sisters.
0:15:42 > 0:15:44I'm the black sheep.
0:15:47 > 0:15:49When d'you two meet?
0:15:49 > 0:15:54Not that that's any of your business, but, erm, last night...
0:15:56 > 0:15:58Get off me!
0:15:58 > 0:16:00- Are you Special Branch?- Johnny!
0:16:00 > 0:16:02Johnny, stop it!
0:16:02 > 0:16:04Johnny, what are you doing?! Get off him! Get off him!
0:16:04 > 0:16:08- He's not who he says he is, Nat. - Oh, my God, Johnny, not this shit again! Shut up!
0:16:08 > 0:16:12- I'm sorry, Ryan, this is my brother...- Whatever.
0:16:17 > 0:16:19You said you didn't have a brother.
0:16:19 > 0:16:21Well, what do you expect?
0:16:21 > 0:16:25I don't see you for months... years, sometimes.
0:16:25 > 0:16:29I never know when you're going to show up, and when you do, you pull this paranoid crap!
0:16:33 > 0:16:34- Don't...- Hey.
0:16:34 > 0:16:36Oi! Nat...
0:16:48 > 0:16:50'How am I supposed to be?'
0:16:50 > 0:16:53Please, for me, all right?
0:16:57 > 0:17:03Oi! Ryan, look, mate, I'm... sorry about all that.
0:17:03 > 0:17:06I've got trust issues.
0:17:06 > 0:17:08Come on, why don't we have a nice cup of tea together,
0:17:08 > 0:17:10get to know each other?
0:17:12 > 0:17:14Natalie, call me if you want to go out again.
0:17:14 > 0:17:18Ryan. Ryan, just...
0:17:19 > 0:17:21Grier's at Natalie's.
0:17:21 > 0:17:24I've got a positive radiation reading from his jacket,
0:17:24 > 0:17:25check the data.
0:17:27 > 0:17:30It's just a trace amount. He doesn't have the source with him.
0:17:30 > 0:17:33Well, he's had more than enough time to stash it somewhere secure.
0:17:33 > 0:17:37- He's been in the country for 24 hours, it could be anywhere. - 'I sprayed his jacket.'
0:17:37 > 0:17:39You should be able to track him.
0:17:39 > 0:17:41- Keep eyes on him.- 'I can't.'
0:17:41 > 0:17:42I had to walk away.
0:17:42 > 0:17:45'He already suspects me. He attacked me.'
0:17:45 > 0:17:49Walking will at least make him wonder if he was right. I might still be able to use this cover.
0:17:49 > 0:17:51I've got Grier.
0:17:51 > 0:17:54A strong signal. He's heading south.
0:17:54 > 0:17:57But we're not surveilling anyone out that way.
0:17:57 > 0:17:59It's where our pet estate agent is, where Dimitri works.
0:17:59 > 0:18:03- You think he's checking up on him? - If he suspects we're on to him, he could go to ground,
0:18:03 > 0:18:05or worse, accelerate his plan.
0:18:07 > 0:18:08MOBILE RINGS
0:18:08 > 0:18:11- Control?- 'Grier's on his way'
0:18:11 > 0:18:14to the estate agents. Less than ten minutes away. Be there now!
0:18:17 > 0:18:21TYRES SCREECH
0:18:36 > 0:18:38Control, I'm not going to make this.
0:18:43 > 0:18:46Can I help you?
0:18:47 > 0:18:50Yeah. Erm, is Ryan around?
0:18:50 > 0:18:51Erm, he's at a viewing.
0:18:51 > 0:18:54Well, that's where I'm supposed to be. Do you have an address?
0:18:55 > 0:18:5946, Shenbourn Street. Shall I call him?
0:19:00 > 0:19:02He's on his way.
0:19:02 > 0:19:03Thanks, Naomi.
0:19:18 > 0:19:24See you over there in ten minutes... OK.
0:19:24 > 0:19:25What are you doing here?
0:19:25 > 0:19:27How long you been an estate agent for?
0:19:27 > 0:19:30What? Erm, ten years...
0:19:30 > 0:19:31How did you know I was here?
0:19:31 > 0:19:35- We all right about this morning? - Yeah.
0:19:36 > 0:19:38You sure?
0:19:40 > 0:19:44Come here. Come here...
0:19:45 > 0:19:48You're insane, do you know that?
0:19:48 > 0:19:51Y'know, it has been said before. See you later.
0:20:05 > 0:20:07Ryan...
0:20:10 > 0:20:14Look, Ryan, erm, if you want to see my sister, that's fine.
0:20:14 > 0:20:16Don't let me put you off.
0:20:16 > 0:20:20I'm not going to be around much anyway. All right?
0:20:22 > 0:20:23All right.
0:20:30 > 0:20:32Control...
0:20:32 > 0:20:34I think we've got him.
0:20:36 > 0:20:38Grier's on the move. The signal's intermittent,
0:20:38 > 0:20:41but I've got six teams on standby ready for hands-off surveillance.
0:20:41 > 0:20:47- And nine units already on Johnny's known associates.- Make sure they vary their patterns every 30 minutes
0:20:47 > 0:20:50- and those on Grier never get direct eye-line to him.- Yep.
0:20:50 > 0:20:53- Any of our teams get made and we're never finding that orphan source. - Cal, with me.
0:20:53 > 0:20:56We'll take point on him ourselves.
0:21:04 > 0:21:05About to have an eyeball on Grier.
0:21:09 > 0:21:11Omega Team, stand down. We have the target.
0:21:24 > 0:21:28Control, see if you can trace a call from a phonebox on...
0:21:28 > 0:21:30Ah, never mind.
0:21:31 > 0:21:34Zeta team are tailing one of Grier's old pals in Leytonstone.
0:21:34 > 0:21:38She just got a phonecall. Looks like she's heading the same way. Could be a meet.
0:21:43 > 0:21:45Quite a party.
0:21:45 > 0:21:47This is bigger than we thought.
0:21:58 > 0:22:02Control, Grier and other potential suspects are meeting
0:22:02 > 0:22:05in the centre of West Hyatt Park. We need tails on all of them.
0:22:05 > 0:22:09- Second from other Sections. Do we have the Osprey?- On its way.
0:22:13 > 0:22:16- Those two seem to be getting a private audience.- Mmm.
0:22:25 > 0:22:27Receiving images.
0:22:29 > 0:22:31Identifying who we can.
0:22:33 > 0:22:36OK, a few are on low-alert watch lists,
0:22:36 > 0:22:39but the man talking to Grier is Joe Blakeson.
0:22:39 > 0:22:42Tried, but never convicted, of supplying the detonators
0:22:42 > 0:22:44for Grier's previous terror effort.
0:22:44 > 0:22:46The last we heard, he was in Germany, waging a campaign against
0:22:46 > 0:22:49big pharmaceuticals with the animal rights groups.
0:22:49 > 0:22:51They're leaving.
0:22:51 > 0:22:55I'll take Blakeson on foot. Hand Johnny over to Kappa team.
0:22:55 > 0:22:57You get back to the Grid.
0:24:10 > 0:24:14Harry thought it was better not to risk another meet with you so soon.
0:24:14 > 0:24:18And you are the one he sends.
0:24:18 > 0:24:19Do you have the communiques?
0:24:35 > 0:24:37My name's Ruth.
0:24:38 > 0:24:42I saw how you were together at the reception, Ruth.
0:24:42 > 0:24:44Harry loves you, doesn't he?
0:24:48 > 0:24:55I have no idea how to answer that question. Or why I ever would.
0:24:55 > 0:24:57But he trusts you though?
0:24:58 > 0:25:01- Not completely.- You can't expect

0:25:05 > 0:25:09He can't even give that to himself.
0:25:13 > 0:25:16FOOTSTEPS APPROACH
0:25:16 > 0:25:18It's OK. He brought me.
0:25:18 > 0:25:20Where's Pearce?
0:25:21 > 0:25:23It wasn't safe for him to come.
0:25:23 > 0:25:28I want to know, when you find out about the messages, Harry comes to me.
0:25:28 > 0:25:31He owes me that... We have to go.
0:25:33 > 0:25:35Thank you, Ruth.
0:25:44 > 0:25:46So, we've got Grier's trust.
0:25:46 > 0:25:49The question is, how do we use it to find the orphan source?
0:25:49 > 0:25:53Calum and I saw Grier use a notebook. We have to get a look at it.
0:25:53 > 0:25:58It's the only place he probably writes everything down. Dimitri, find a pretext to get back there tonight.
0:25:58 > 0:26:03- But I only met the guy this morning, if I go back in this soon, it'll look suspicious.- Agreed.
0:26:03 > 0:26:05But we can't afford to play the long game.
0:26:05 > 0:26:08We still face the threat of an imminent dirty bomb attack.
0:26:08 > 0:26:12Grier may be the only person who knows where the source is. We can't pull him in.
0:26:12 > 0:26:17Especially now there's a second serious operator like Blakeson in the mix. We'll have to push it,
0:26:17 > 0:26:19and accept the risk of doing so.

0:26:30 > 0:26:33'Discuss it over dinner with me tonight?'
0:26:33 > 0:26:36I expect a warmly patriotic reply.
0:26:36 > 0:26:38Of course, Home Secretary.
0:26:38 > 0:26:40Someone will be in touch.

0:27:05 > 0:27:07I, um...
0:27:07 > 0:27:10I was supposed to be having dinner at my parents' house,
0:27:10 > 0:27:12but they cancelled on me.
0:27:12 > 0:27:14- So, new low.- Ha!
0:27:14 > 0:27:17What are you doing here?
0:27:19 > 0:27:23- I just thought I'd swing by. This morning was a bit...- Yeah.
0:27:25 > 0:27:28Is there somewhere nice we could have a drink round here?
0:27:28 > 0:27:35No! Erm, but let's go anyway. Just give me a sec. Come in.
0:28:09 > 0:28:11Are you looking for something?
0:28:14 > 0:28:17Dropped a quid.
0:28:19 > 0:28:22Well, it's nice to see you again... so soon.
0:28:25 > 0:28:26Nat and I are going for a drink.
0:28:26 > 0:28:29Join us, if you like.
0:28:29 > 0:28:35As long as you promise not to attack me again.
0:28:35 > 0:28:36Yeah. Why not?
0:28:43 > 0:28:47I thought it'd be a good idea to get your mad brother onside if, um...
0:28:47 > 0:28:50we're going to see each other.
0:28:52 > 0:28:53Right.
0:29:25 > 0:29:2817th November, 1982.
0:29:28 > 0:29:31The mists aren't parting.
0:29:32 > 0:29:37The Kiselow Ballet only performed in West Berlin once.
0:29:37 > 0:29:39On that date.
0:29:41 > 0:29:46Yes, it was Elena's cover, where Ilya thought she was going for the evening.
0:29:46 > 0:29:49There's no mention of it in the records.
0:29:49 > 0:29:51It wasn't an official operation.
0:29:55 > 0:29:59One of the messages does mention that night.
0:29:59 > 0:30:01And as it wasn't a sanctioned op,
0:30:01 > 0:30:04I'm assuming not that many people knew about it?
0:30:04 > 0:30:09Just me, Elena...and Jim Coaver.
0:30:10 > 0:30:13Harry, if Jim Coaver wrote these messages,
0:30:13 > 0:30:16if he tricked Elena into thinking he was you,
0:30:16 > 0:30:21then we need to consider that he was involved in the attempted hit on Gavrik.
0:30:23 > 0:30:24MOBILE PHONE RINGS
0:30:26 > 0:30:28- Got the notebook?- 'No.'
0:30:28 > 0:30:31I looked in his jacket, he must have hidden it somewhere.
0:30:31 > 0:30:33'Look, I've got them out of the house.'
0:30:33 > 0:30:36Give you a chance to do a search.
0:30:37 > 0:30:40He's really got it sewn up. No, seriously.
0:30:40 > 0:30:42Talking about the arms dealers, right?
0:30:42 > 0:30:44You've got Dictator A, who plays ball.
0:30:44 > 0:30:48Great, so we sell him our bombs. Now, Dictator B's not toeing the line.
0:30:48 > 0:30:49So what do we do?
0:30:49 > 0:30:53We drop 'em on his head. No, either way, the bastards always make sure
0:30:53 > 0:30:54there's a demand going...

0:31:05 > 0:31:07Oh, Johnny knows everything.
0:31:07 > 0:31:10His teachers always used to say...
0:31:10 > 0:31:12he'd either change the world or end up in prison.
0:31:12 > 0:31:14He's tried both.
0:31:14 > 0:31:19- He's been to prison? What for? - Oh, just stupid stuff.
0:31:19 > 0:31:23He has crazy ideas about things.
0:31:26 > 0:31:28Our parents...
0:31:28 > 0:31:34Well, they wasn't parents, so Johnny looked after me.
0:31:35 > 0:31:39- So, who'd you vote for last time then, Ryan?- I didn't bother.
0:31:39 > 0:31:42- They're all as bad as each other. There's no point.- You're not wrong.
0:31:42 > 0:31:46Every time I come back to this country, it seems to be getting worse. It really breaks your heart.
0:31:46 > 0:31:50The government and the banks risk everything, nearly lose it all, so what do we do?
0:31:50 > 0:31:55Put it back into the hands of the same corrupt, vicious bastards. It's the definition of madness.
0:31:55 > 0:31:57And next time, and the time after that, and the time after that,
0:31:57 > 0:32:03there's not going to be any going back. The system's broken and nobody cares. I mean, what do we care?
0:32:03 > 0:32:06We're all being trained to sit in our own little bubbles,

0:32:14 > 0:32:15What did you say?
0:32:15 > 0:32:17For God's sake, Johnny, don't... Just...
0:32:17 > 0:32:22I'm sorry, I thought you heard me the first time. I said it nice and loud so you could... SCUM!
0:32:26 > 0:32:29Look, he's only mucking about.
0:32:31 > 0:32:33Do you want to say something to us?
0:32:35 > 0:32:36Yeah.
0:32:36 > 0:32:37Johnny!
0:32:42 > 0:32:45- Well, come on then, scum! You're still lying on the floor?- Johnny!
0:32:45 > 0:32:47- Get out of it!- Johnny, let's go!
0:33:05 > 0:33:06I've got the notebook.

0:33:29 > 0:33:30Cal!
0:33:32 > 0:33:34Nat, come on.
0:33:40 > 0:33:43Nat, I said I'm sorry, come on. I got carried away.
0:33:43 > 0:33:46- What do you want me to say?- Just go and sit down. I'll make tea.
0:33:47 > 0:33:50- So, Ryan, you took a nice little slap back there.- Yeah.
0:33:50 > 0:33:52Haven't been in a fight since school.
0:33:52 > 0:33:55You know what, Nat, forget the tea. I've got stuff to do.
0:33:55 > 0:33:59I'll be back in the morning, all right?
0:34:07 > 0:34:09Johnny's on the move.
0:34:09 > 0:34:12'Something's up. Tell surveillance teams to stand by.'
0:34:18 > 0:34:20I don't blame you if you want to go.
0:34:20 > 0:34:24He's what you call a 'character'. I quite like him.
0:34:24 > 0:34:27God, don't YOU fall under his spell.
0:34:27 > 0:34:30You're supposed to be falling under mine.
0:34:36 > 0:34:40I know this is probably, erm, weird...
0:34:40 > 0:34:42we just met yesterday, but...
0:34:43 > 0:34:46..are you busy this weekend? It's just...
0:34:46 > 0:34:49if you want to go somewhere, just me and you, I mean.
0:34:49 > 0:34:53Leave Johnny behind...
0:34:57 > 0:35:00Yeah... Yeah, that'd be nice.
0:35:00 > 0:35:02Yeah?
0:35:22 > 0:35:25So, who's been running my mother?
0:35:25 > 0:35:27The CIA contacted her, pretending to be me,
0:35:27 > 0:35:31to get information about the Partnership.
0:35:31 > 0:35:33- I need a name.- No.
0:35:33 > 0:35:36You've already killed your friend to keep this secret.
0:35:36 > 0:35:39You don't want to continue down that road, believe me.
0:35:40 > 0:35:45Sasha, Elena's secret is safe. I'll take care of the rest.
0:35:45 > 0:35:49You and I, our paths need never cross again.
0:35:59 > 0:36:01Why did you come in person?
0:36:03 > 0:36:06You could have sent that woman. Anyone.
0:36:08 > 0:36:11No particular reason.
0:36:49 > 0:36:54I'm requesting secure point-to-point connection from location G99,

0:36:55 > 0:37:00Yeah. Violet 36 sigma, beta 2483.
0:37:06 > 0:37:09I'm still not entirely sure why I'd be necessary, Home Secretary.
0:37:09 > 0:37:14I'm a hoarder of intellects. It's how I make myself look good.
0:37:14 > 0:37:16And the power map is being redrawn.
0:37:16 > 0:37:20I need to be ahead of the curve. But tell me about yourself, Ruth...
0:37:20 > 0:37:23If I may call you that?
0:37:23 > 0:37:25Are you married? Children?
0:37:25 > 0:37:27Well, there's not much to tell, really.
0:37:27 > 0:37:31I'm not married, no children.
0:37:31 > 0:37:36I did have something like that for a while, but it ended.
0:37:36 > 0:37:41In all honesty, I suppose you'd have to say that outside of my work,
0:37:41 > 0:37:46my life has been, erm...
0:37:46 > 0:37:47small.
0:37:50 > 0:37:53- You embody my pet hate, you know. - I'm sorry?
0:37:53 > 0:37:55Stifled potential. I see it all the time.
0:37:55 > 0:37:59Minds get blocked somewhere along the way, locked into something -
0:37:59 > 0:38:03an institution, a relationship - that freezes them where they are.
0:38:03 > 0:38:07- Home Secretary, I really... - If you do work for me,
0:38:07 > 0:38:09you'll call me William.
0:38:09 > 0:38:12And you'll stop looking at your feet.
0:38:14 > 0:38:18Am I unable to free you from Harry's tentacles?
0:38:20 > 0:38:22I don't want to be the homewrecker.
0:38:23 > 0:38:26It's not that.
0:38:26 > 0:38:29Harry and I will always be... important to each other, but...
0:38:35 > 0:38:40I know this is an odd thing to complain about in my line of work,
0:38:40 > 0:38:45but I'm sick of secrets. They stop you ever knowing people.

0:39:22 > 0:39:25Grier spent the night at a friend's squat. Nothing suspicious.
0:39:25 > 0:39:30Then he's back at Natalie's this morning. But I've got something from your comms bug in the van.
0:39:30 > 0:39:32Transcripts...between Blakeson and his female counterpart.
0:39:32 > 0:39:36Now, they've been talking about a target using a codeword. Crucible.
0:39:36 > 0:39:40She slipped up. Just once.
0:39:41 > 0:39:44- Velanon.- It's a multinational.
0:39:44 > 0:39:46Energy, retail, currency trading,
0:39:46 > 0:39:48and arms.
0:39:48 > 0:39:52They acquired lots of Eastern Bloc energy companies.
0:39:52 > 0:39:56- One of the big three the government's persuaded to move back to London. - We need to talk to their CEO.
0:39:56 > 0:39:58But what makes this lot so deserving of a dirty bomb?
0:39:58 > 0:40:03We got a lot of numbers from Grier's notebook. Nothing helpful, we're on most of his contacts.
0:40:03 > 0:40:07No clue as to where he's keeping the source, but there was this.
0:40:07 > 0:40:12Practice letters to Natalie. Goodbye letters.
0:40:14 > 0:40:15It's a suicide mission.
0:40:17 > 0:40:21Tell Dimitri, from now on, Johnny Grier does not leave his sight.

0:40:37 > 0:40:39Mr Reddon?
0:40:40 > 0:40:44Ah, my people told me you were coming. Take a seat.
0:40:44 > 0:40:46Thank you.
0:40:46 > 0:40:49So, we have intelligence that suggests an anarchist terrorist
0:40:49 > 0:40:53is planning an attack on the Velanon group company.
0:40:53 > 0:40:57Something worse than throwing a brick through the window then, eh? What, with you lot here.
0:40:57 > 0:41:01We believe there may be a radiological element to the attack.
0:41:01 > 0:41:04What we can't work out is...why you?
0:41:04 > 0:41:06Why did I ever agree to come back to this shithole?
0:41:06 > 0:41:11Look, Velanon trades currency to take advantage of...
0:41:11 > 0:41:14well, unfortunate events abroad.
0:41:14 > 0:41:18A few months ago, we made almost a billion, trading the yen.
0:41:18 > 0:41:21So, you profit on a nuclear accident?
0:41:21 > 0:41:25The anarchists find out and want to give you a little back.
0:41:25 > 0:41:27Rather droll of them, wouldn't you say?
0:41:27 > 0:41:28Disaster capitalism.
0:41:28 > 0:41:33And our government fell over itself to woo you back here.
0:41:33 > 0:41:36Insulting me isn't wise. I'll see that comes back to you.
0:41:36 > 0:41:40What's your name? Your real one?!
0:41:40 > 0:41:43I will make sure you get one of our customer comments cards.

0:41:58 > 0:42:00The attack's underway. Grier may not be the bomber.
0:42:00 > 0:42:03Call CO19, have them bring him in. Tell Dimitri
0:42:03 > 0:42:05he's got until then to break him.
0:42:07 > 0:42:09- PHONE BLEEPS - Ah, it's the boss.
0:42:09 > 0:42:12Take it. I'm going to jump in the shower.
0:42:12 > 0:42:16- Ryan speaking.- Blakeson and the woman have gone dark.
0:42:16 > 0:42:18The attacks are happening right now. Have you been briefed on
0:42:18 > 0:42:23- 'Velanon and Peter Reddon?'- Yeah, yeah. I got Ruth's message.- 'See if you can get the target off Grier.'
0:42:23 > 0:42:25Push him. CO19 are ten minutes away.
0:42:25 > 0:42:27'You have that time before your cover's blown.'
0:42:41 > 0:42:44I was thinking about what you said last night.
0:42:44 > 0:42:49- Yeah? What about it?- Well...
0:42:49 > 0:42:53what can we do about it? How can we change people?
0:42:53 > 0:42:59One mind at a time. There's a term in anarchist thought.
0:42:59 > 0:43:02'Propaganda of the deed'. Every action has its own message.
0:43:10 > 0:43:13As long as people need to control other people,
0:43:13 > 0:43:17there'll always be a state. There'll be censorship, there'll be taxes, there'll be secret police.
0:43:17 > 0:43:19I mean, what am I going to do about it?
0:43:19 > 0:43:27Rage, rage against the dying light?
0:43:27 > 0:43:28No.
0:43:40 > 0:43:44These are cancer drugs, Johnny. What are you doing with these?
0:43:48 > 0:43:50It's pancreatic.
0:43:52 > 0:43:53Terminal.
0:43:58 > 0:44:02Where is it? The stuff you smuggled into the country.
0:44:02 > 0:44:04You ARE a copper.
0:44:04 > 0:44:08You need to tell me, Johnny, what have you done with it?
0:44:10 > 0:44:12The heroin?
0:44:13 > 0:44:17- Her... Heroin?- Yeah, my friends paid for my flight over here.
0:44:17 > 0:44:21To return the favour, I smuggled some smack in for them.
0:44:21 > 0:44:23Did you look at it?
0:44:24 > 0:44:26No, of course not. It was sealed up.
0:44:28 > 0:44:30That wasn't heroin.
0:44:30 > 0:44:33It was radioactive material.
0:44:37 > 0:44:39What are you talking about?
0:44:41 > 0:44:42If you're lying to me,
0:44:42 > 0:44:47I'll go straight up those stairs and I'll tell Natalie exactly what we're both doing here.
0:44:47 > 0:44:51She was planning to take you away for the weekend, you heartless bastard.
0:44:51 > 0:44:56Radiation? I don't know nothing about no radiation.
0:44:56 > 0:44:58The only reason I came back was to say goodbye to Nat.
0:45:00 > 0:45:02Your friends are making a dirty bomb.
0:45:02 > 0:45:07Did they say anything to you about it?
0:45:07 > 0:45:12No. I mean, they knew I was dying,
0:45:12 > 0:45:17I guess they figured it didn't matter if I brought this stuff over.
0:45:31 > 0:45:34Control... Johnny Grier's not part of the bomb plot.
0:45:34 > 0:45:37'He didn't know what he was smuggling in.'
0:45:37 > 0:45:38Are you sure about this?
0:45:38 > 0:45:41It's my judgement that Johnny wouldn't be part of a plot
0:45:41 > 0:45:43to kill innocent people.
0:45:43 > 0:45:46The other anarchists have dumped us. If Grier's not involved,
0:45:46 > 0:45:48we're out of options.
0:45:52 > 0:45:54Maybe not.
0:45:54 > 0:45:58Your friends, do you have a way to contact them?
0:45:58 > 0:46:01- Might have. - They're really going to do this.
0:46:03 > 0:46:04Help us.
0:46:04 > 0:46:07Find out where. If you don't help,
0:46:07 > 0:46:10innocent people will die today.
0:46:23 > 0:46:27All right. I'll do it, but you stay here.
0:46:27 > 0:46:30I'll call you when I've spoken to them. When I come back,
0:46:30 > 0:46:35you and I are going to have a little talk about how you used my sister.
0:46:37 > 0:46:39Fair enough.

0:47:07 > 0:47:11He's been stationary for the last two minutes.
0:47:11 > 0:47:13He's at a phonebox in the city.
0:47:16 > 0:47:20'Ryan, it's Johnny, I've got it. The target is Velanon's'

0:48:06 > 0:48:11- Drop it now!- Get down! Get down!
0:48:32 > 0:48:35The van's empty... There's no bomb.
0:48:35 > 0:48:40'The van's empty, it was a diversion. Alpha Two, do you copy?
0:48:40 > 0:48:45'Either Grier's been played by his friends, or he lied to you!'
0:48:45 > 0:48:46- Nat...- Mmm?
0:48:46 > 0:48:51- When did you tell your brother about us spending the weekend together?- What? Oh, I didn't.
0:48:54 > 0:48:56'Dimitri, Grier's driving back'
0:48:56 > 0:48:58towards you. He's two streets away
0:48:58 > 0:49:02'from the house.' HE SIGHS
0:49:03 > 0:49:07Erm... I've forgot about a viewing. I'll call you later.

0:49:16 > 0:49:19- Who are you?- What?- Where's Johnny?
0:49:19 > 0:49:20Now, look, calm down!
0:49:20 > 0:49:23Some bloke just gave me 50 quid to take his car home, all right?
0:49:26 > 0:49:27Control,
0:49:27 > 0:49:30'he's dumped me too. He'd bugged me.'
0:49:30 > 0:49:32He's known who I am all along.
0:49:32 > 0:49:35Alpha Two, you're the one that knows him. Think.
0:49:35 > 0:49:38'What's he doing?'
0:49:38 > 0:49:43OK. He wants to send the clearest message. Propaganda...
0:49:43 > 0:49:46'of the deed. He'll have picked up the source.
0:49:46 > 0:49:49'He wanted us to think that he was attacking a Velanon building.'
0:49:49 > 0:49:52He knew we'd protect every site, send all the staff home...
0:49:54 > 0:49:55Where's Reddon?
0:49:55 > 0:49:57'Are we protecting him?'
0:49:57 > 0:49:59Er, no, he has his own security.
0:49:59 > 0:50:03He's gone to a group office in West London.
0:50:03 > 0:50:05Alpha Two, he wasn't supposed to go.
0:50:05 > 0:50:08- 'We told him to stay away from his offices.' - That's what Johnny wanted!
0:50:08 > 0:50:11'He's going after Reddon. It's an assassination.'

0:52:40 > 0:52:42Don't worry. It's safe for now,

0:52:47 > 0:52:52Please, put it down.
0:53:01 > 0:53:04You know, I stole this from a cancer clinic in Greece.
0:53:04 > 0:53:09Same sort of stuff the docs used to try and save my life.
0:53:11 > 0:53:13Funny that, isn't it?

0:53:28 > 0:53:33OK... I won't tell her who I really am. Ever.
0:53:34 > 0:53:38As long as you put that down and come with me.
0:53:40 > 0:53:43Killing Reddon with radiation, after what he did, I get it.
0:53:43 > 0:53:51Sends a message. But you, dying alone in here, it means nothing.
0:53:51 > 0:53:54It won't get reported for what it is, you know that.
0:53:54 > 0:54:02No-one's going to learn anything. No-one's watching, Johnny.
0:54:07 > 0:54:09You are.
0:54:23 > 0:54:25'Several office buildings in West London'
0:54:25 > 0:54:27were evacuated today following a chemical leak
0:54:27 > 0:54:31at a nearby technology park. Police say a small amount of

0:54:35 > 0:54:37were also cleared as a precautionary measure.

0:55:33 > 0:55:36If someone was breaking up with me, it's what I'd want to get.

0:55:56 > 0:55:59MOBILE PHONE BLEEPS
0:56:27 > 0:56:29You all need to see this.
0:56:30 > 0:56:33- What is it?- The night Tariq died,
0:56:33 > 0:56:35he'd traced the muggers who stole our laptop.
0:56:35 > 0:56:38They were meeting this woman. Someone was monitoring him.
0:56:38 > 0:56:42This was in his pocket. He saw something they didn't want him to,
0:56:42 > 0:56:46so they attacked his system, then killed him.
0:56:46 > 0:56:47Who is she?
0:56:47 > 0:56:50I don't have a name, but her face crops up
0:56:50 > 0:56:52in a file that speculates she's a deniable asset
0:56:52 > 0:56:58for a little outfit called the Central Intelligence Agency.
0:57:00 > 0:57:04That's not all. I found her somewhere else.
0:57:06 > 0:57:09The assassination attempt on Gavrik, at the reception.
0:57:10 > 0:57:12She was there.
0:57:14 > 0:57:17Harry, what is it?
0:57:17 > 0:57:19Tell them, Ruth.
0:57:24 > 0:57:28Jim Coaver has been posing as Harry
0:57:28 > 0:57:32to get information from Elena Gavrik. He may have had something
0:57:32 > 0:57:34to do with the hit on her husband.
0:57:34 > 0:57:37What?! Why weren't we told?
0:57:37 > 0:57:40Harry has history with these people.
0:57:40 > 0:57:42He wanted to deal with it himself.
0:57:45 > 0:57:47But if this woman's working for Coaver,
0:57:47 > 0:57:50he wasn't just behind the hit on Gavrik.
0:57:51 > 0:57:54He's responsible for stealing our intel too.
0:57:54 > 0:57:55That would mean...
0:57:58 > 0:57:59..the CIA killed Tariq.
0:58:14 > 0:58:16I know these people. They have one purpose -
0:58:16 > 0:58:18killing.
0:58:18 > 0:58:21- They're planning a revenge attack, here in London.- Do the Americans
0:58:21 > 0:58:25- know we are discussing intelligence sharing?- Huh!
0:58:25 > 0:58:28Do you know what it's like to feel something for someone,
0:58:28 > 0:58:29then realise you don't even know them?
0:58:29 > 0:58:3224 hours, Jim, then I'm coming after you.

0:58:43 > 0:58:44as dead.
0:58:44 > 0:58:46- Give me an update! I need an update! - Proceed.
