0:00:02 > 0:00:05Doctor, it's Martha. And I'm bringing you back to Earth.
0:00:05 > 0:00:0852 deaths at the exact same moment, worldwide.
0:00:08 > 0:00:10- All inside their cars. - They were all fitted with ATMOS.
0:00:10 > 0:00:14ATMOS can be threaded through any and every make of car.
0:00:14 > 0:00:17- Get back!- Then they've got poisonous gas in every car on earth.
0:00:18 > 0:00:22- Sontaran!- General Staal of the tenth Sontaran fleet.
0:00:26 > 0:00:29- And this is Ross. - Good afternoon, sir.
0:00:31 > 0:00:33What is that?
0:00:33 > 0:00:36Soon, THAT will be you.
0:00:36 > 0:00:39- Now we begin.- Martha, tell Colonel Mace it's the Sontarans.
0:00:39 > 0:00:42Code Red Sontaran. If they're in the factory
0:00:42 > 0:00:45tell him not to start shooting, UNIT will get massacred.
0:00:45 > 0:00:46Code Red Sontaran. Gotcha.
0:00:46 > 0:00:49- Found anything yet? - Nothing to report.
0:00:49 > 0:00:51Prepare the subjugation of Earth!
0:00:51 > 0:00:55Sontar-ha! Sontar-ha! Sontar-ha! Sontar-ha!
0:00:57 > 0:00:59Doctor!
0:01:37 > 0:01:40He's gonna choke! Doctor!
0:01:42 > 0:01:44It won't open!
0:01:49 > 0:01:51Well, don't just stand there!
0:01:51 > 0:01:53Get him out!
0:01:53 > 0:01:56All soldiers to a door!
0:01:56 > 0:01:58Take positions on the ground floor.
0:01:58 > 0:02:00Wicowsky!
0:02:00 > 0:02:03Take the soldiers into the factory! Make the area secure!
0:02:03 > 0:02:04Seal off doors and windows!
0:02:04 > 0:02:06We've tried everything, it won't stop.
0:02:09 > 0:02:12- What have we got? - ATMOS is running wild, sir.
0:02:12 > 0:02:15It can't be stopped, it's everywhere. The whole planet.
0:02:15 > 0:02:18ALARM SOUNDS
0:02:35 > 0:02:36Thanks!
0:02:36 > 0:02:38- I can't believe you've got an axe! - Burglars?
0:02:38 > 0:02:41Get inside, try to close off doors and windows.
0:02:41 > 0:02:44Doctor! This is all I could find but it hasn't got ATMOS.
0:02:44 > 0:02:45- Donna, you coming?- Yeah.
0:02:45 > 0:02:49Don't go. Look what happens every time that Doctor appears.
0:02:49 > 0:02:52- Stay with us, please. - You go, my darlin'.- Dad!
0:02:52 > 0:02:54Don't listen to her.
0:02:54 > 0:02:56You go with The Doctor.
0:02:56 > 0:02:58That's my girl!
0:03:00 > 0:03:01Bye.
0:03:16 > 0:03:18SIREN WAILS
0:03:41 > 0:03:44Success. The Operative has the necessary information.
0:03:44 > 0:03:47Good work, for a female. Now she must be protected.
0:03:47 > 0:03:49I will prepare an attack squad.
0:03:50 > 0:03:53This is it, isn't it?
0:03:53 > 0:03:56Oh, man. This is war!
0:03:56 > 0:03:57And how does it feel, boy?
0:03:57 > 0:03:59Magnificent!
0:04:00 > 0:04:03The government has declared a state of emergency.
0:04:03 > 0:04:06People are being told to stay away from all cars
0:04:06 > 0:04:08with ATMOS devices attached.
0:04:08 > 0:04:10The gas appears to be toxic.
0:04:10 > 0:04:14We're warning anyone and everyone, stay away from the cars.
0:04:14 > 0:04:16Repeat, stay away from your cars.
0:04:23 > 0:04:26- Ross, look after yourself. Get inside the building!- Will do.
0:04:26 > 0:04:28Greyhound 40 to Trap One.
0:04:28 > 0:04:30I've just returned The Doctor to base, over.
0:04:30 > 0:04:33Trap One, received. Over.
0:04:33 > 0:04:35Sir! Message from The Doctor.
0:04:35 > 0:04:38He says Code Red Sontaran.
0:04:38 > 0:04:42All troops. Code Red Sontaran. Code Red Sontaran.
0:04:42 > 0:04:44The air is disgusting.
0:04:44 > 0:04:46It's not so bad for me. Get inside the TARDIS. Oh!
0:04:46 > 0:04:48I've never given you a key.
0:04:48 > 0:04:50That's yours. Quite a big moment, really.
0:04:50 > 0:04:54Maybe we can get sentimental after the world's choked to death.
0:04:54 > 0:04:57- Good idea!- Where are you going?
0:04:57 > 0:04:58To stop a war!
0:05:15 > 0:05:19Here I am! Whatever you do, Colonel Mace, do not engage the Sontarans in battle.
0:05:19 > 0:05:22There is nothing they like better than a war! Leave this to me.
0:05:22 > 0:05:26- And what are you going to do? - I've got the TARDIS, I'm gonna get on board their ship.
0:05:32 > 0:05:33Come on.
0:05:52 > 0:05:53Ready for transport.
0:06:12 > 0:06:14The spoils of war.
0:06:14 > 0:06:19The Doctor's infamous vessel in Sontaran hands.
0:06:19 > 0:06:22It's time I made a move, sir. I have soldiers of my own.
0:06:22 > 0:06:25I'll tell them of the honour and the glory, sir.
0:06:25 > 0:06:28I'll tell them that Planetfall is coming!
0:06:31 > 0:06:34He is behaving exactly as predicted, sir.
0:06:34 > 0:06:37None of the humans can guess our true purpose.
0:06:41 > 0:06:43But...
0:06:43 > 0:06:45- where's the Tardis?- Taste that,
0:06:45 > 0:06:47in the air. Yecch.
0:06:47 > 0:06:50That sort of metal tang.
0:06:50 > 0:06:53Teleport exchange.
0:06:53 > 0:06:56It's the Sontarans, they've taken it.
0:06:57 > 0:06:58I'm stuck.
0:06:58 > 0:07:01On Earth, like...
0:07:01 > 0:07:04Like an ordinary person. Like a Human! How rubbish is that!
0:07:04 > 0:07:06Sorry, no offence, but come on!
0:07:06 > 0:07:09- So, what do we do?- Well...
0:07:09 > 0:07:12It's shielded, they could never detect it.
0:07:14 > 0:07:17- What?- I'm just wondering. Have you phoned your family and Tom?
0:07:17 > 0:07:19- No, what for?- The gas.
0:07:19 > 0:07:21Tell them to stay inside.
0:07:21 > 0:07:25Course I will, yeah. But what about Donna?
0:07:25 > 0:07:27I mean, where's she?
0:07:27 > 0:07:29Oh, she's gone home.
0:07:29 > 0:07:32She's not like you, she's not a soldier.
0:07:32 > 0:07:34Right. So, avanti!
0:07:43 > 0:07:45Leave it.
0:07:45 > 0:07:47Turn away.
0:07:47 > 0:07:49Civilisation is falling!
0:07:49 > 0:07:52But it's all over the news, sir, it's everywhere.
0:07:52 > 0:07:54Paris and New York.
0:07:54 > 0:07:57It's time I told you, all of you.
0:07:57 > 0:08:00It's time I revealed what our work has been for.
0:08:00 > 0:08:03- Change of plan!- Good to have you fighting alongside us, Doctor.
0:08:03 > 0:08:07I'm not. I'm not-fighting, as in not hyphen fighting, got it?
0:08:07 > 0:08:11- Now, does anyone know what this gas is yet?- We're working on it.
0:08:11 > 0:08:14It's harmful but not lethal until it reaches 80% density.
0:08:14 > 0:08:17We're having the first reports of deaths from Tokyo City.
0:08:17 > 0:08:19And who are you?
0:08:19 > 0:08:22- Captain Marion Price, sir.- Oh, put your hand down. Don't salute.
0:08:22 > 0:08:26Jodrell Bank's traced a signal coming from 5,000 miles above Earth.
0:08:26 > 0:08:30- We're guessing that's what triggered the cars.- The Sontaran ship.
0:08:30 > 0:08:32NATO has gone to Defcon One, we're preparing a strike.
0:08:32 > 0:08:37Nuclear missiles won't even scratch the surface. Let me talk to the Sontarans.
0:08:37 > 0:08:41- You're not authorised to speak on behalf of the Earth. - Oh, I earned that a long time ago.
0:08:41 > 0:08:44Calling the Sontaran Command Ship under Jurisdiction Two
0:08:44 > 0:08:48of the Intergalactic Rules of Engagement. This is The Doctor.
0:08:48 > 0:08:52Doctor, I'm here. Can you hear me?
0:08:52 > 0:08:54Doctor. Breathing your last?
0:08:54 > 0:08:56My God. They're like trolls.
0:08:56 > 0:08:59Yeah, loving the diplomacy, thanks.
0:08:59 > 0:09:03So, tell me, General Staal.
0:09:03 > 0:09:07- Since when did you lot become cowards?- How dare you!
0:09:07 > 0:09:08Oh, that's diplomacy?
0:09:08 > 0:09:10Doctor! You impugn my honour!
0:09:10 > 0:09:16Yeah. I'm really glad you didn't say belittle cos then I'd have a field day. But poison gas?
0:09:16 > 0:09:19That's the weapon of a coward and you know it.
0:09:19 > 0:09:22Staal, you could blast this planet out of the sky.
0:09:22 > 0:09:24And yet you're sitting up above watching it die.
0:09:24 > 0:09:27Where's the fight in that? Where's the honour?
0:09:27 > 0:09:30Or are you lot planning something else?
0:09:30 > 0:09:34Cos this isn't normal Sontaran warfare. What are you lot up to?
0:09:34 > 0:09:39A General would be unwise to reveal his strategy to the opposing forces.
0:09:39 > 0:09:42Ahhh, the war's not going so well, then? Losing, are we?
0:09:42 > 0:09:44Such a suggestion is impossible.
0:09:44 > 0:09:47- What war?- The war between the Sontarans and the Rutans.
0:09:47 > 0:09:52It's been raging, far out in the stars, for 50,000 years.
0:09:52 > 0:09:5650,000 years of bloodshed. And for what?
0:09:56 > 0:09:59For victory! Sontar-ha!
0:09:59 > 0:10:03Sontar-ha! Sontar-ha! Sontar-ha!
0:10:05 > 0:10:06Give me a break.
0:10:09 > 0:10:15Doctor, I would seriously recommend that this dialogue is handled by official Earth representation.
0:10:15 > 0:10:20- Finished?- You will not be so quick to ridicule when you see our prize.
0:10:20 > 0:10:22Behold!
0:10:22 > 0:10:26We are the first Sontarans in history to capture a TARDIS!
0:10:26 > 0:10:30Well, as prizes go, that's...
0:10:30 > 0:10:36Noble. As they say in Latin, "Donna" nobis pacem.
0:10:36 > 0:10:40- That's me. I'm here!- But did you never wonder about its design?
0:10:40 > 0:10:45It's a phone box, it contains a phone. A telephonic device for communication.
0:10:45 > 0:10:46It's sort of symbolic.
0:10:46 > 0:10:49Like, if only we could communicate, you and I.
0:10:49 > 0:10:52All you have communicated is your distress, Doctor.
0:10:52 > 0:10:54Oh, my God.
0:10:54 > 0:10:57Big mistake though, showing it to me.
0:10:57 > 0:10:58But who do I phone?
0:10:58 > 0:11:00Cos I've got a remote control.
0:11:00 > 0:11:02Cease transmission!
0:11:02 > 0:11:05Doctor! What number are you on?
0:11:06 > 0:11:07You haven't even got a number!
0:11:07 > 0:11:12Remove the box from the War Room, beyond the transmission field.
0:11:12 > 0:11:16- Well, that achieved nothing. - Oh, you'd be surprised.
0:11:22 > 0:11:24But what do I do?
0:11:24 > 0:11:27All this stuff we've been building.
0:11:27 > 0:11:30All this invention. Where's it been heading?
0:11:30 > 0:11:35Gravity densifiers, hydroponics, atmospheric conversion, ecoshells.
0:11:35 > 0:11:37More than enough to build a brand new world!
0:11:37 > 0:11:41Luke, we haven't got time for this. I've got to find my parents.
0:11:41 > 0:11:43Oh, but this isn't just theory.
0:11:45 > 0:11:47I'm talking Planetfall. For all of us.
0:11:47 > 0:11:50A brand new start, for a brand new human race. Look.
0:11:53 > 0:11:59A new world. Far out, beyond Alpha Geminorum, just waiting for us.
0:11:59 > 0:12:04Its official designation is Castor 36. I think of it as Earth 0.2.
0:12:06 > 0:12:08I did wonder about Rattigan's World.
0:12:08 > 0:12:11- But we can take a vote on that. - What the hell are you on about?
0:12:11 > 0:12:13This is where we're going.
0:12:13 > 0:12:16I have partners. Willing to take us there.
0:12:16 > 0:12:19Oh, he's lost it, I haven't got time for this.
0:12:19 > 0:12:22- Where are you going? - To find my brother.
0:12:22 > 0:12:25- I didn't say you could leave. - I told him to put ATMOS in his car,
0:12:25 > 0:12:28- I've got to go and help him. - Stay where you are!
0:12:30 > 0:12:33- what do you think you're doing? - Luke... Put that down.
0:12:36 > 0:12:38I did this for you. Don't you see?
0:12:38 > 0:12:41We've spent all our lives excluded.
0:12:41 > 0:12:42The clever ones.
0:12:42 > 0:12:45They've laughed at us and pulled us down,
0:12:45 > 0:12:49those ordinary people out there. Those...cattle.
0:12:49 > 0:12:53- This is our chance to leave them behind.- You mean you want them dead?
0:12:53 > 0:12:55And I chose you to survive!
0:12:57 > 0:13:01With Planetfall, we can start again.
0:13:01 > 0:13:04We can build and breed, we can prosper, we can do anything!
0:13:04 > 0:13:06We're going to breed?
0:13:06 > 0:13:09I've designed a mating programme. I've planned the whole thing!
0:13:09 > 0:13:12Well, then. Shoot me.
0:13:12 > 0:13:14Stay where you are!
0:13:14 > 0:13:15Stay where you are, I said!
0:13:15 > 0:13:18Stay where you are, that's an order!
0:13:25 > 0:13:27Castor 36?
0:13:29 > 0:13:31You're just sick.
0:13:34 > 0:13:37Guess that just proves it.
0:13:37 > 0:13:39I'm cleverer than you!
0:13:39 > 0:13:43I'm cleverer than everyone! D'you hear me? I'm clever!
0:13:43 > 0:13:47The United Nations has issued a directive worldwide,
0:13:47 > 0:13:50telling urban populations to stay indoors.
0:13:50 > 0:13:53Those in rural areas are being ordered
0:13:53 > 0:13:55to stay away from all major cities.
0:13:55 > 0:13:58There are reports from every country in Europe
0:13:58 > 0:14:01of thousands of people walking across country to escape.
0:14:01 > 0:14:05And on the Eastern seaboard of America, it's said to be reminiscent
0:14:05 > 0:14:09of Dunkirk with boats taking refugees out into the Atlantic.
0:14:09 > 0:14:14With the freeways blocked by ATMOS cars, populations of major cities
0:14:14 > 0:14:18are now walking across open country to escape the fumes.
0:14:18 > 0:14:20It is being likened to a Biblical plague.
0:14:20 > 0:14:22Some are calling this the End of Days.
0:14:30 > 0:14:32"Mum? You all right?"
0:14:32 > 0:14:35- Donna! Where are you, sweetheart? - Is that her?
0:14:35 > 0:14:37Oh, just finish the job.
0:14:37 > 0:14:39Your Grandad's sealing us in.
0:14:39 > 0:14:44He's sealing the windows. Our own house, and we're sealed in.
0:14:44 > 0:14:47All those things they said about pollution and ozone and carbon,
0:14:49 > 0:14:51they're really happening, aren't they?
0:14:51 > 0:14:55There's people working on it, Mum. They're gonna fix it, I promise.
0:14:55 > 0:14:57Oh, like you'd know, you're so clever?
0:14:57 > 0:15:00Oh, don't start. Please don't.
0:15:00 > 0:15:02I'm sorry.
0:15:02 > 0:15:05- I wish you were here.- Now, come on Sylvia, look. That doesn't help.
0:15:05 > 0:15:07Donna? Where are you?
0:15:10 > 0:15:13It's sort of hard to say.
0:15:13 > 0:15:16- You all right? - Yeah, fighting fit, yeah.
0:15:16 > 0:15:19- Is he with you, The Doctor? - Oh, The Doctor!
0:15:20 > 0:15:21No.
0:15:21 > 0:15:26- I'm all on my own.- Look, you promised he was gonna look after you.
0:15:26 > 0:15:28He will, Gramps.
0:15:28 > 0:15:31There's something he needs me to do. I just don't know what.
0:15:31 > 0:15:35Well, the whole place is covered, all of London, they're saying. The whole world.
0:15:35 > 0:15:39It's the scale of it, Donna. I mean, how can one man stop all that?
0:15:39 > 0:15:41Trust me. He can do it.
0:15:41 > 0:15:46Yeah, well, if he doesn't, you tell him he'll have to answer to me.
0:15:46 > 0:15:49I will.
0:15:49 > 0:15:51Just as soon as I see him,
0:15:51 > 0:15:53I'll tell him.
0:16:19 > 0:16:24Carbon monoxide, hydrocarbons, nitrogen oxides but 10% unidentified.
0:16:24 > 0:16:26Some sort of artificial heavy element.
0:16:26 > 0:16:30- Ever seen anything like it?- Must be invented by the Sontarans.
0:16:30 > 0:16:33This isn't just poison. They need it for something else. But what?
0:16:33 > 0:16:37- Launch grid online and active! - Defcon One initiatives in progress.
0:16:37 > 0:16:38What?! I told you not to launch!
0:16:38 > 0:16:41The gas is at 60% density.
0:16:41 > 0:16:4380% and people start dying. We've got no choice.
0:16:43 > 0:16:46Launching in 60,
0:16:46 > 0:16:4859,
0:16:48 > 0:16:5058,
0:16:50 > 0:16:5357, 56...
0:16:53 > 0:16:56Worldwide nuclear grid now co-ordinating.
0:16:56 > 0:16:5954, 53...
0:17:00 > 0:17:02The planet is going nuclear!
0:17:02 > 0:17:07I admire them. The bravery of idiots is bravery nonetheless.
0:17:07 > 0:17:09The Operative is in place, sir.
0:17:09 > 0:17:12Commander Skorr! Is the Attack Squad ready?
0:17:12 > 0:17:14Ready and eager for battle, sir!
0:17:14 > 0:17:17It'll be good to taste blood.
0:17:19 > 0:17:23You're making a mistake, Colonel. For once, I hope the Sontarans are ahead of you.
0:17:23 > 0:17:25North America, online.
0:17:25 > 0:17:27United Kingdom, online.
0:17:27 > 0:17:32France, online. India, online.
0:17:32 > 0:17:34Pakistan, online.

0:17:54 > 0:17:550.
0:18:04 > 0:18:06What is it? What happened?
0:18:06 > 0:18:09Did we launch? Well? Did we?
0:18:09 > 0:18:10Negative, sir.
0:18:10 > 0:18:15- The launch codes have been wiped, sir. Must be the Sontarans. - Can we override it?
0:18:15 > 0:18:18- Trying it now, sir.- Missiles wouldn't even dent that ship,
0:18:18 > 0:18:20so why are the Sontarans so keen to stop you?
0:18:20 > 0:18:22Any ideas?
0:18:22 > 0:18:24How should I know?
0:18:24 > 0:18:26Now protect the Operative!
0:18:45 > 0:18:46Stinking out there.
0:18:46 > 0:18:49SOLDIERS CHAT
0:18:50 > 0:18:52Sssh. Keep it down, lads.
0:18:54 > 0:18:58Enemy within! At arms! Greyhound 40 declaring absolute emergency.
0:18:58 > 0:19:02Sontarans within factory grounds, east corridor grid six.
0:19:02 > 0:19:04Absolute emergency, declaring Code Red.
0:19:04 > 0:19:07- All troops, Code Red! - Get them out of there!
0:19:08 > 0:19:09All troops, open fire!
0:19:14 > 0:19:17The guns aren't working. Inform all troops, standard weapons do not work.
0:19:20 > 0:19:22SCREAMING
0:19:22 > 0:19:25Tell The Doctor it's that Cordolaine signal.
0:19:25 > 0:19:27He's the only one who can stop them.
0:19:33 > 0:19:35STATIC
0:19:37 > 0:19:40Greyhound 40, report. Over.
0:19:40 > 0:19:42Greyhound 40, report.
0:19:44 > 0:19:46Greyhound 40, report.
0:19:48 > 0:19:52He wasn't Greyhound 40, his name was Ross.
0:19:52 > 0:19:56Now, listen to me and GET THEM OUT OF THERE!
0:19:59 > 0:20:01Trap One to all stations.
0:20:01 > 0:20:03Retreat.
0:20:03 > 0:20:06- Order imperative, immediate retreat! - Retreat! Retreat!
0:20:20 > 0:20:22Reporting for duty, sir.
0:20:27 > 0:20:32This is too easy. They're running like slimebait from a speelfox.
0:20:47 > 0:20:50This isn't war, this is sport!
0:20:55 > 0:21:00- They've taken the factory. - Why? They don't need it, why attack now? What are they up to?
0:21:00 > 0:21:03Times like this, I could do with the Brigadier.
0:21:03 > 0:21:05- No offence.- None taken.
0:21:05 > 0:21:10Sir Alistair's a fine man, if not the best. Unfortunately, he's stranded in Peru.
0:21:10 > 0:21:12Launch grid back online.
0:21:18 > 0:21:21They're inside the system, sir. It's coming from within UNIT itself.
0:21:21 > 0:21:25Trace it, find out where it's coming from and quickly! Gas levels?
0:21:25 > 0:21:3066% in major population areas and rising.
0:21:30 > 0:21:33Commander Skorr reports victory with many glorious deaths.
0:21:35 > 0:21:37I'm sorry to report, sir,
0:21:37 > 0:21:40I've failed.
0:21:40 > 0:21:42They wouldn't come.
0:21:42 > 0:21:45The students, they didn't have the imagination to believe.
0:21:45 > 0:21:48A pity.
0:21:48 > 0:21:50We've lost our target practice!
0:21:52 > 0:21:57- What do you mean?- Upon arrival on board this ship, your students would have been shot down.
0:21:57 > 0:22:00Perhaps they were more clever than you thought.
0:22:02 > 0:22:04- You promised... - There was no Planetfall!
0:22:04 > 0:22:08Castor 36, indeed!
0:22:08 > 0:22:11We only needed you for installation of the ATMOS system.
0:22:11 > 0:22:14No, but I'm on your side.
0:22:15 > 0:22:16I did everything you wanted.
0:22:18 > 0:22:20And it's not ATMOS-system, that's a tautology.
0:22:20 > 0:22:22- It's just ATMOS.- Execute him!
0:22:24 > 0:22:26A coward's retreat.
0:22:26 > 0:22:30Now close all teleport links to Earth.
0:22:30 > 0:22:34Isolate them as they perish.
0:22:34 > 0:22:36SOBBING
0:22:47 > 0:22:50Why are they defending the factory only after we're inside?
0:22:50 > 0:22:52Because they wanted UNIT here.
0:22:52 > 0:22:58You gave them something they needed, something now hidden inside the factory.
0:22:58 > 0:23:00- Something precious. - We've got to recover it.
0:23:00 > 0:23:05- How does this Cordolaine signal work?- It's the bullets. Causes expansion of the copper shell.
0:23:05 > 0:23:09- I'm on it.- For the billionth time, you can't fight Sontarans!
0:23:12 > 0:23:16Phone, have you got a phone? I need your mobile, quickly, hurry up.
0:23:22 > 0:23:24MOBILE PHONE RINGS
0:23:25 > 0:23:30- What's happened, where are you? - Earth. But don't worry. I've got my secret weapon.
0:23:30 > 0:23:31- And what's that?- You!
0:23:31 > 0:23:34Somehow, that's not making me happy.
0:23:34 > 0:23:37Can't you just zap us down to Earth with that remote?
0:23:37 > 0:23:40I haven't got a remote, though I should. I need you there.
0:23:40 > 0:23:44That's why I made them move the TARDIS. I'm sorry, but you've got to go outside.
0:23:44 > 0:23:45There's Sonterruns out there.
0:23:45 > 0:23:48Sontarans. They'll be on battle stations right now.
0:23:48 > 0:23:51I can talk you through it.
0:23:51 > 0:23:53But what if they find me?
0:23:53 > 0:23:56I know, but there is nothing else I can do.
0:23:56 > 0:23:58The whole planet is choking, Donna.
0:24:01 > 0:24:03What do you need me to do?
0:24:03 > 0:24:05The Sontarans have got a teleport link with the ship.
0:24:05 > 0:24:08They'll have deadlocked it. I need you to reopen it.
0:24:08 > 0:24:13- I can't even mend a fuse.- Stop talking about yourself like that. You can do this, I promise.
0:24:25 > 0:24:27There's a Sonterrun... Sontaran.
0:24:27 > 0:24:30- Did he see you?- No, he's got his back to me.
0:24:30 > 0:24:33On the back of his neck there's a sort of plug, like a hole.
0:24:33 > 0:24:36The Probic Vent. One blow to the Probic Vent knocks 'em out.
0:24:36 > 0:24:38- But he's gonna kill me.- I'm sorry.
0:24:38 > 0:24:40I'm so sorry. But you've got to try.
0:25:10 > 0:25:12Back of the neck!
0:25:13 > 0:25:16Now find the external junction feed to the teleport.
0:25:16 > 0:25:20- What's it look like? - "Circular panel on the wall."
0:25:20 > 0:25:25Big symbol on the front, like a letter T with a horizontal line through it. Or two Fs back to back.
0:25:25 > 0:25:27Well, there's a door.
0:25:27 > 0:25:29- Should be a switch by the side. - There is.
0:25:29 > 0:25:31It's Sontaran-shaped, you need three fingers.
0:25:31 > 0:25:33You've got three fingers.
0:25:33 > 0:25:35Oh, yeah.
0:25:43 > 0:25:46- "I'm through." - Oh, you are brilliant, you are.
0:25:48 > 0:25:49Shut up.
0:25:49 > 0:25:51Right.
0:25:51 > 0:25:53T with a line through it.
0:25:53 > 0:25:57- Got to go. Keep the line open! - Counter-attack!
0:25:57 > 0:26:01- I said you don't stand a chance! - Positions. That means everyone!
0:26:05 > 0:26:08- You're not going without me. - Wouldn't dream of it.
0:26:33 > 0:26:36- Latest firing stock, what do you think, Doctor?- Are you my mummy?
0:26:36 > 0:26:38If you could concentrate.
0:26:38 > 0:26:42Bullets with a rad-steel coating, no copper surface.
0:26:42 > 0:26:44Should overcome the Cordolaine signal.
0:26:44 > 0:26:45But the Sontarans have lasers!
0:26:45 > 0:26:48You can't even see in this fog, night-vision doesn't work.
0:26:48 > 0:26:50Thank you for your lack of faith.
0:26:50 > 0:26:54But this time, I'm not listening.
0:26:54 > 0:26:56Attention, all troops!
0:26:56 > 0:26:59The Sontarans might think of us as primitive.
0:26:59 > 0:27:03As does every passing species with an axe to grind.
0:27:03 > 0:27:07They make a mockery of our weapons, our soldiers, our ideals.
0:27:07 > 0:27:10But no more! From this point on, it stops.
0:27:10 > 0:27:15From this point on, the people of Earth fight back and we show them!
0:27:15 > 0:27:18We show the warriors of Sontar what the human race can do!
0:27:18 > 0:27:22Trap One to Hawk Major! Go, go, go!
0:27:30 > 0:27:33It's working. The area's clearing.
0:27:34 > 0:27:37Engines to maximum!
0:27:37 > 0:27:38It's the Valiant!
0:27:44 > 0:27:48UNIT Carrier Ship Valiant reporting for duty, Doctor!
0:27:48 > 0:27:52With engines strong enough to clear away the fog.
0:28:04 > 0:28:07- That's brilliant! - Getting a taste for it, Doctor?
0:28:07 > 0:28:10No, not at all. Not me.
0:28:10 > 0:28:11Valiant, fire at will!
0:28:36 > 0:28:38East and north secure. Doctor?
0:28:38 > 0:28:40Donna, hold on. I'm coming.
0:28:40 > 0:28:42Shouldn't we follow the Colonel?
0:28:42 > 0:28:45Nah, you and me, Martha Jones. Just like old times!
0:28:45 > 0:28:47Alien technology, this way!
0:28:53 > 0:28:57The honour of battle. The glory!
0:29:05 > 0:29:08No Sontarans down here.
0:29:08 > 0:29:10They can't resist a battle.
0:29:10 > 0:29:11Here we go.
0:29:31 > 0:29:33Ohh, Martha. I'm so sorry.
0:29:33 > 0:29:36Still alive.
0:29:39 > 0:29:42Am I supposed to be impressed?
0:29:42 > 0:29:44- Wish you carried a gun now? - Not at all.
0:29:44 > 0:29:48- I've been stopping the nuclear launch all this time. - Doing exactly what I wanted.
0:29:48 > 0:29:51I needed to stop the missiles, as much as the Sontarans.
0:29:51 > 0:29:54I'm not having Earth start an interstellar war.
0:29:54 > 0:29:56- You're a triple agent!- When did you know?- Right from the start.
0:29:56 > 0:30:00Reduced iris contraction, thinning of the hair on the left temple.
0:30:00 > 0:30:02And, frankly, you smell.
0:30:02 > 0:30:05You might as well have worn a T-shirt saying "clone".
0:30:05 > 0:30:07Although maybe not in front of Captain Jack.
0:30:07 > 0:30:11You remember him, don't you? Cos you've got all her memories.
0:30:11 > 0:30:15That's why the Sontarans had to protect her,
0:30:15 > 0:30:17to keep you inside UNIT.
0:30:17 > 0:30:20Martha Jones is keeping you alive.
0:30:24 > 0:30:28It's all right. It's all right, I'm here, I'm here. I've got you.
0:30:28 > 0:30:31There was this thing, Doctor, this alien, with this head...
0:30:31 > 0:30:33PHONE RINGS
0:30:33 > 0:30:34Blimey, I'm busy. Got it?
0:30:34 > 0:30:38- Yes. Now hurry up! - "Take off the covering."
0:30:38 > 0:30:41All the blue switches inside, flick them up like a fusebox.
0:30:41 > 0:30:43And that should get the teleport working.
0:30:43 > 0:30:46Oh, my God.
0:30:46 > 0:30:48That's me.
0:30:49 > 0:30:51You will face me, sir!
0:30:57 > 0:30:59Wonderful.
0:31:07 > 0:31:09Don't touch me!
0:31:09 > 0:31:11It's not my fault.
0:31:11 > 0:31:15The Sontarans created you. But you had all my memories.
0:31:15 > 0:31:20You've got a brother, sister, mother and father.
0:31:20 > 0:31:22If you don't help me, they're going to die.
0:31:22 > 0:31:24You love them.
0:31:24 > 0:31:26Yes. Remember that?
0:31:27 > 0:31:28The gas! Tell us about the gas.
0:31:28 > 0:31:31- He's the enemy!- Then tell me.
0:31:31 > 0:31:34It's not just poison, what's it for? Martha, please.
0:31:38 > 0:31:41Caesofine concentrate.
0:31:41 > 0:31:44It's one part Bosteen,
0:31:44 > 0:31:46- two parts Probic 5.- Clonefeed!
0:31:46 > 0:31:48It's clonefeed!
0:31:48 > 0:31:51- What's clonefeed? - Like amniotic fluid, for Sontarans.
0:31:51 > 0:31:53They're converting the atmosphere.
0:31:53 > 0:31:56Changing the planet into a clone world. Earth becomes a hatchery.
0:31:56 > 0:31:59The Sontarans are clones, it's how they reproduce.
0:31:59 > 0:32:03Give 'em a planet this big, they'll create billions of new soldiers.
0:32:03 > 0:32:05That gas isn't poison, it's food!
0:32:07 > 0:32:10My heart... It's getting slower.
0:32:10 > 0:32:12There's nothing I can do.
0:32:12 > 0:32:15In your mind, you've got so many plans.
0:32:15 > 0:32:17There's so much that you want to do.
0:32:17 > 0:32:21And I will. Never do tomorrow what you can do today, my mum says.
0:32:21 > 0:32:24- Cos...- Cos you never know how long you've got.
0:32:26 > 0:32:28Martha Jones...
0:32:28 > 0:32:30All that life.
0:33:01 > 0:33:03Doctor.
0:33:04 > 0:33:07Blue switches done.
0:33:10 > 0:33:11But they've found me!
0:33:12 > 0:33:13Now!
0:33:18 > 0:33:20Have I ever told you how much I hate you?
0:33:20 > 0:33:22Hold on, hold on. Get off me, get off me!
0:33:22 > 0:33:24Gotta bring the TARDIS down.
0:33:28 > 0:33:32- Right, now. Martha, you coming? - What about this nuclear launch?
0:33:32 > 0:33:35Just keep pressing N, we want to keep those missiles on the ground.
0:33:37 > 0:33:38But there's...
0:33:38 > 0:33:41- Two of them.- Yeah, long story.
0:33:43 > 0:33:45Here we go. The old team, back together!
0:33:45 > 0:33:47Well, the new team.
0:33:47 > 0:33:49- We're not going back on that ship! - No, no.
0:33:49 > 0:33:52I needed to get the teleport working so we could get to...
0:33:53 > 0:33:56Here! The Rattigan Academy, owned by...
0:33:56 > 0:34:00Don't tell anyone what I did. The Sontarans lied to me.
0:34:00 > 0:34:02If I see one more gun...
0:34:06 > 0:34:10You know, that coat sort of works.
0:34:10 > 0:34:12Feel like a kid in my Dad's clothes.
0:34:12 > 0:34:15If you're calling him Dad you're getting over him.
0:34:15 > 0:34:18A human female, on board ship.
0:34:18 > 0:34:23It could only be The Doctor's work and all the teleport systems have been deadlocked open.
0:34:23 > 0:34:27No matter. Increase the ATMOS devices to maximum.
0:34:27 > 0:34:29Choke them!
0:34:29 > 0:34:32Behold, the cloneworld is born.
0:34:32 > 0:34:35ALARM BLARES
0:34:38 > 0:34:40ENGINE REVVING
0:34:50 > 0:34:52Oh, my little girl.
0:34:52 > 0:34:54Come on. We'll be all right.
0:34:54 > 0:34:56We'll be all right. Donna said so.
0:34:56 > 0:34:58She promised.
0:34:58 > 0:35:01Come on, darling. It's all right.
0:35:01 > 0:35:05That's why the Sontarans stopped the missiles, to hold back.
0:35:06 > 0:35:10caesofine gas is volatile, so they used you to stop the nuclear attack.
0:35:10 > 0:35:13Ground-to-air engagement could've sparked it off.
0:35:13 > 0:35:16- What, set fire to the atmosphere? - Yeah. They need the gas to breed their army.
0:35:16 > 0:35:20And all the time we had Luke here. Planning a little trip, were we?
0:35:20 > 0:35:22- They promised me a new world. - And you built equipment
0:35:22 > 0:35:24ready to terraform El Mondo Luko,
0:35:24 > 0:35:29so that humans could live there and breathe the air with this!
0:35:29 > 0:35:30An atmospheric convertor.
0:35:34 > 0:35:39Prepare to launch clone pods. We will breed across the surface of the earth.
0:35:39 > 0:35:41For the glory of Sontar!
0:35:52 > 0:35:56That's London. You can't even see it.
0:35:56 > 0:36:01- My family's in there. - If I can get this on the right setting...- Doctor, hold on.
0:36:01 > 0:36:04- You said the atmosphere would ignite.- Yeah. I did, didn't I?
0:36:20 > 0:36:22Please, please, please, please...
0:36:38 > 0:36:41General Staal, sir.
0:36:41 > 0:36:42What's happening?
0:36:42 > 0:36:45ALARM BLARES
0:37:43 > 0:37:46He's a genius!
0:37:46 > 0:37:48- Just brilliant! - Now we're in trouble.
0:37:50 > 0:37:55It seems we must revert to Basic Sontaran Stratagem One.
0:37:55 > 0:37:57We will ravage this planet.
0:37:57 > 0:37:59Prepare weapons! Wipe them out!
0:37:59 > 0:38:02Every last stinking human beast!
0:38:03 > 0:38:06Right, so...
0:38:06 > 0:38:09Donna. Thank you, for everything.
0:38:09 > 0:38:11Martha, you too.
0:38:11 > 0:38:14Oh...so many times.
0:38:16 > 0:38:19Luke. Do something clever with your life.
0:38:21 > 0:38:25- You're saying goodbye. - Sontarans are never defeated.
0:38:25 > 0:38:27They'll be getting ready for war.
0:38:27 > 0:38:32And, well, you know, I've recalibrated this for Sontaran air, so...
0:38:33 > 0:38:36You're gonna ignite them.
0:38:38 > 0:38:40You'll kill yourself.
0:38:40 > 0:38:42Just send that thing up, on its own.
0:38:42 > 0:38:44I dunno, put it on a delay.
0:38:46 > 0:38:47I can't.
0:38:49 > 0:38:51Why not?
0:38:51 > 0:38:54I've got to give them a choice.
0:39:19 > 0:39:21Oh, excellent.
0:39:21 > 0:39:24General Staal. You know what this is.
0:39:24 > 0:39:25But there's one more option.
0:39:25 > 0:39:28You can go, just leave.
0:39:28 > 0:39:31Sontaran High Command need never know what happened.
0:39:31 > 0:39:36Your stratagem would be wise if Sontarans feared death. But we do not.
0:39:36 > 0:39:38At arms!
0:39:42 > 0:39:45If it saves the Earth, I'll do it.
0:39:45 > 0:39:48- A warrior doesn't talk, he acts! - I am giving you the chance to leave.
0:39:48 > 0:39:51And miss the glory of this moment?
0:39:51 > 0:39:54- All weapons targeting Earth, sir. Firing in 20.- I warn you!
0:39:54 > 0:39:56And I salute you! Take aim!
0:39:56 > 0:39:59Shoot me, I'm still gonna press this. You'll die, Staal.
0:39:59 > 0:40:01Knowing that you die, too.
0:40:01 > 0:40:03- Firing in 15. - For the glory of Sontar!
0:40:03 > 0:40:05Sontar-ha! Sontar-ha! Sontar-ha!
0:40:05 > 0:40:08Sontar-ha! Sontar-ha!
0:40:08 > 0:40:11Sontar-ha! Sontar-ha!
0:40:14 > 0:40:17- Sontar-ha! Sontar-ha! Sontar-ha!- I'll do it!
0:40:17 > 0:40:18- Then do it!- Sontar-ha!
0:40:20 > 0:40:22- What are you doing? - Something clever.
0:40:24 > 0:40:2610, 9, 8,
0:40:26 > 0:40:297, 6, 5,
0:40:29 > 0:40:314, 3...
0:40:31 > 0:40:34- Sontar-ha!- ..2, 1.
0:41:14 > 0:41:17- Morning.- Morning.
0:41:17 > 0:41:20Walked all the way, won't catch me driving.
0:41:24 > 0:41:28The streets are half-empty. People still aren't driving.
0:41:28 > 0:41:33There's kids on bikes all over the place, it's wonderful.
0:41:33 > 0:41:36Unpack that lot, I'm gonna see if Suzette's all right.
0:41:39 > 0:41:41I won't tell her.
0:41:41 > 0:41:43Best not.
0:41:45 > 0:41:48Just keep it as our little secret, eh?
0:41:48 > 0:41:51Yeah.
0:41:51 > 0:41:55And you go with him, that wonderful Doctor.
0:41:55 > 0:41:57You go and see the stars.
0:42:00 > 0:42:05And then bring a bit of 'em back, for your old gramps.
0:42:22 > 0:42:23Love you.
0:42:35 > 0:42:37How were they?
0:42:39 > 0:42:42Oh, same old stuff.
0:42:42 > 0:42:44They're fine.
0:42:44 > 0:42:48So! You gonna come with us? We're not exactly short of space.
0:42:48 > 0:42:51Oh, I have missed all this.
0:42:51 > 0:42:54But, you know. I'm good here.
0:42:54 > 0:42:57Back at home.
0:42:57 > 0:42:58And I'm better for having been away.
0:42:58 > 0:43:02Besides, someone needs me.
0:43:02 > 0:43:05Never mind the universe, I've got a big world of my own now.
0:43:09 > 0:43:11What?! What?
0:43:14 > 0:43:17- Doctor! Don't you dare!- No, no, no! I didn't touch anything!
0:43:17 > 0:43:20We're in flight, it's not me!
0:43:20 > 0:43:24- Where are we going? - I dunno, it's out of control!
0:43:28 > 0:43:31Doctor, just listen to me, you take me home!
0:43:31 > 0:43:33Take me home right now!
0:43:44 > 0:43:48- Where did she come from?- From me.
0:43:48 > 0:43:51From you? How?
0:43:53 > 0:43:54Well...
0:43:57 > 0:43:58I'd like to see you try that.
0:44:02 > 0:44:04She's my daughter.
0:44:05 > 0:44:07Hello, Dad.
