0:00:02 > 0:00:07But who is this creature with terrible claws,
0:00:07 > 0:00:11terrible teeth in his terrible jaws?
0:00:13 > 0:00:14Go on, your bit...
0:00:17 > 0:00:20He, he has... Go on!
0:00:20 > 0:00:23I can't do it, Dad. I can listen to books, anyway.
0:00:23 > 0:00:27I know it doesn't come easy, son, but you've got to keep at it, all right?
0:00:27 > 0:00:29You're not on your own with this.
0:00:29 > 0:00:32Mo, you'll be late for your shift!
0:00:32 > 0:00:34Oh, you're right!
0:00:34 > 0:00:36Sorry, El, got to go.
0:00:36 > 0:00:38Now, who loves you more than me?
0:00:38 > 0:00:41- No-one.- Stop saying that!
0:00:57 > 0:01:00Approaching stage four, target drilling depth.
0:01:00 > 0:01:05Stage four target drill depth scheduled in five, four, three, two, one.
0:01:05 > 0:01:09Stage four target drill depth achieved.
0:01:09 > 0:01:13- Drill depth now 21 kilometres.- Hi.
0:01:13 > 0:01:16Nasreen here, just to let you know we have just hit our new target!
0:01:16 > 0:01:1821 kilometres, folks!
0:01:18 > 0:01:21Further than anyone's ever drilled into the Earth.
0:01:21 > 0:01:24Thanks for your amazing work. Have a great weekend!
0:01:24 > 0:01:26Onwards and downwards.
0:01:26 > 0:01:30- How much further do you think we can we go, Mack?- Into the unknown!
0:01:30 > 0:01:35- Exciting, isn't it? - Yeah.- Aye, aye! Stop that!
0:01:35 > 0:01:36The real worker's here now!
0:01:36 > 0:01:39- Evening, Mo!- 21k?
0:01:40 > 0:01:43You wanted to grab all the glory before I come on shift!
0:01:43 > 0:01:47Right, off you go, get out, my gaff for the night.
0:02:03 > 0:02:05Brilliant.
0:02:06 > 0:02:09RATTLING
0:03:11 > 0:03:14That is mad.
0:03:35 > 0:03:37Oh!
0:03:37 > 0:03:38Please...
0:03:45 > 0:03:47Ahh!
0:03:50 > 0:03:52Argh!
0:04:31 > 0:04:35Behold...Rio!
0:04:39 > 0:04:43- Nuh-uh.- Not really getting the sunshine carnival vibe.- No.
0:04:43 > 0:04:46Ooh, feel that, though, what's that?
0:04:49 > 0:04:51Ground feels strange...
0:04:52 > 0:04:55Just me. Wait...
0:04:55 > 0:04:58- That's weird.- What's weird?
0:04:58 > 0:05:01Doctor, stop trying to distract us. We're in the wrong place.
0:05:01 > 0:05:03Doctor, it's freezing and I've dressed for Rio.
0:05:03 > 0:05:06We are not stopping here.
0:05:06 > 0:05:08Doctor! You listening to me?
0:05:08 > 0:05:12- It's a graveyard! You promised me a beach.- Blue grass.
0:05:14 > 0:05:16Patches of it all round the graveyard.
0:05:16 > 0:05:19So, Earth, 2020-ish, ten years in your future,
0:05:19 > 0:05:23wrong continent for Rio, I'll admit, but it's not a massive overshoot.
0:05:23 > 0:05:25Why are those people waving at us?
0:05:28 > 0:05:29Can't be.
0:05:34 > 0:05:35It is!
0:05:36 > 0:05:38It's you two.
0:05:38 > 0:05:42No, we're here. How can we be up there?!
0:05:42 > 0:05:46Ten years in your future. Come to relive past glories, I'd imagine.
0:05:46 > 0:05:48Humans, you're so nostalgic.
0:05:48 > 0:05:51We're still together in ten years?
0:05:51 > 0:05:53No need to sound so surprised!
0:05:53 > 0:05:57Hey, let's go and talk to them! We can say hi to Future Us! How cool is that?
0:05:57 > 0:05:59No, best not, really best not.
0:05:59 > 0:06:03These things get complicated very quickly, and...oh, look!
0:06:03 > 0:06:06Big mining thing.
0:06:06 > 0:06:08Oh, I love a big mining thing.
0:06:08 > 0:06:10See, way better than Rio!
0:06:10 > 0:06:12Rio doesn't have a big mining thing.
0:06:12 > 0:06:17- We're not going to have a look, are we?- Let's go and have a look!
0:06:17 > 0:06:20- Come on, let's see what they're doing.- If he can't get us to Rio,
0:06:20 > 0:06:21how's he ever going to get us back home?
0:06:21 > 0:06:23Did you not see, over there? It all works out fine.
0:06:23 > 0:06:28After everything we've seen, we just drop back into our old lives, the nurse and the kissogram?
0:06:28 > 0:06:32- I guess. He's getting away.- Hang on.
0:06:32 > 0:06:34What are you doing with that?
0:06:34 > 0:06:37- Engagement ring! I thought you liked me wearing it. - Amy! You could lose it!
0:06:37 > 0:06:41Cost...a lot of money, that!
0:06:41 > 0:06:42Hm.
0:06:44 > 0:06:46Spoilsport.
0:06:46 > 0:06:49- Go on. I'll catch you both up. - Doctor!
0:06:54 > 0:06:56The drill's shut down! There's no sign of Mo.
0:06:56 > 0:07:02Nobody's been in or out of the perimeter between last night...and...now. What's that?
0:07:02 > 0:07:05That wasn't there last night. How the hell did that get there?
0:07:05 > 0:07:06I don't know.
0:07:24 > 0:07:26Well, that was quick!
0:07:26 > 0:07:29- Was it?- It's great that you came.
0:07:31 > 0:07:34Bit retro. What is it, portable crime lab?
0:07:34 > 0:07:36- Oh. Er, sort of.- Ambrose Northover.
0:07:36 > 0:07:38I was the one who called.
0:07:38 > 0:07:42I run the meals on wheels for the whole valley. This is my son, Elliot.
0:07:42 > 0:07:43Where's your uniform?
0:07:43 > 0:07:46Don't be cheeky, Elliot, he's plain clothes.
0:07:46 > 0:07:49CID, is it? Anyway, it's over here.
0:07:53 > 0:07:56Um... OK...
0:08:00 > 0:08:02Restricted access.
0:08:02 > 0:08:05No unauthorised personnel. Mm.
0:08:08 > 0:08:11- That is breaking and entering. - What did I break?!
0:08:11 > 0:08:13Sonicing and entering, totally different.
0:08:20 > 0:08:22Come on, then.
0:08:22 > 0:08:24You're sure Rory'll catch us up?
0:08:25 > 0:08:29It's a family plot, see. My aunt Gladys died six years ago.
0:08:29 > 0:08:32Her husband, Alun, died a few weeks back.
0:08:32 > 0:08:34He lived in the house two doors down.
0:08:34 > 0:08:36There's not many of us left up here now.
0:08:36 > 0:08:40Mum, he doesn't care about that! He wants to know about the dead bodies.
0:08:40 > 0:08:42Yes. Sorry.
0:08:42 > 0:08:47Well, they always wanted to be buried in the same plot, together.
0:08:47 > 0:08:52But when we went to bury Uncle Alun, Gladys wasn't there. Gone.
0:08:52 > 0:08:55Body, coffin, everything.
0:08:57 > 0:08:59What?
0:08:59 > 0:09:02The mad thing is, on the surface, the grave was untouched.
0:09:02 > 0:09:06No signs of it having been messed with.
0:09:06 > 0:09:08I'm sorry, I don't understand.
0:09:08 > 0:09:12Nobody has touched the grave since my aunt was buried.
0:09:12 > 0:09:15But when they dug it open, the body was gone.
0:09:15 > 0:09:17How is that possible?
0:09:21 > 0:09:25- What about now, can you feel it now? - Honestly, I've got no idea what you're on about.
0:09:27 > 0:09:29The ground doesn't feel like it should.
0:09:29 > 0:09:33It's ten years in the future, maybe how this ground feels is how it always feels.
0:09:33 > 0:09:35Good thought! But no. It doesn't.
0:09:35 > 0:09:37WHIRRING Hear that, drill in start-up mode.
0:09:37 > 0:09:41Afterwaves of a recent seismological shift and blue grass.
0:09:43 > 0:09:47Oh, please! Have you always been this disgusting?
0:09:47 > 0:09:50No, that's recent. What's in...
0:09:50 > 0:09:53here?
0:09:53 > 0:09:55- Hello!- Who are you?
0:09:55 > 0:09:58What're you doing here? And what're you wearing?
0:09:58 > 0:09:59I dressed for Rio!
0:09:59 > 0:10:03Ministry of Drills, Earth and Science! New Ministry, quite big, just merged,
0:10:03 > 0:10:08lot of responsibility on our shoulders, don't like to talk about it. What're you doing?
0:10:08 > 0:10:09None of your business.
0:10:12 > 0:10:14Where are you getting these readings from?
0:10:14 > 0:10:18- Under the soil. - The drill's up and running again.
0:10:18 > 0:10:20What's going on? Who are these people?
0:10:20 > 0:10:23Amy, the Doctor. We're not staying, are we, Doctor?!
0:10:23 > 0:10:25Why's there a big patch of earth in the middle of your floor?
0:10:25 > 0:10:28We don't know, it just appeared overnight.
0:10:29 > 0:10:33Good, right, you all need to get out of here very fast.
0:10:33 > 0:10:36- Why?- What's your name? - Nasreen Chaudhry.
0:10:36 > 0:10:41- Look at the screens, Nasreen, your readings. It's moving.- Hey, that's specialised equipment!
0:10:41 > 0:10:43- Get away from it.- What is?
0:10:45 > 0:10:48Doctor, this steam, is that a good thing?
0:10:49 > 0:10:53Shouldn't think so. It's shifting when it shouldn't be shifting.
0:10:53 > 0:10:55What shouldn't?
0:10:59 > 0:11:01The ground, the soil, the earth, moving, but how? Why?
0:11:01 > 0:11:03- Earthquake?- What's going on?
0:11:03 > 0:11:07Doubt it. Cos it's only happening under this room.
0:11:14 > 0:11:19- It knows we're here. The ground's attacking us.- Not possible!- Under the circumstances, I suggest...
0:11:19 > 0:11:22RUN!
0:11:28 > 0:11:31- Tony!- Stay back, Amy! Stay away from the earth!
0:11:33 > 0:11:34It's OK.
0:11:36 > 0:11:40- It's pulling me down!- Amy! - Doctor, help me, something's got me!
0:11:42 > 0:11:43Doctor, the ground's got my legs.
0:11:46 > 0:11:47- I've got you.- OK.
0:11:49 > 0:11:51- Don't let go.- Never.
0:11:51 > 0:11:53Doctor, what is it, why is it doing this?
0:11:53 > 0:11:56Stay calm, keep hold of my hand, don't let go.
0:11:56 > 0:12:00Your drill, shut it down! Go! Now!
0:12:01 > 0:12:03- Can you get me out? - Amy, try and stay calm.
0:12:03 > 0:12:06If you struggle, it'll make things worse. Keep hold of my hand.
0:12:06 > 0:12:10Shut down all drilling activity as quick as you can.
0:12:10 > 0:12:13Reducing main unit power.
0:12:14 > 0:12:15I'm not going to let you go.
0:12:18 > 0:12:21- Doctor, it's pulling me down, something's pulling me!- Stay calm.
0:12:21 > 0:12:26Hold on, if they can just shut down the drill...
0:12:26 > 0:12:29- I can't hold on! - Tony, we have got to be faster!
0:12:29 > 0:12:32I'm doing my best!
0:12:32 > 0:12:34Come on, shut down!
0:12:34 > 0:12:35What's pulling me?
0:12:35 > 0:12:39What is under the earth? I don't want to suffocate under there.
0:12:39 > 0:12:41Amy, concentrate.
0:12:41 > 0:12:44Don't you give up!
0:12:44 > 0:12:47- Tell Rory...- No.
0:12:49 > 0:12:51Amy!
0:12:53 > 0:12:55Amy, no! No! No!
0:12:55 > 0:12:59No! No! No!
0:12:59 > 0:13:01No.
0:13:01 > 0:13:04No!
0:13:04 > 0:13:07No. No. No.
0:13:07 > 0:13:09No!
0:13:20 > 0:13:21Where is she?
0:13:23 > 0:13:28She's gone. The ground took her.
0:13:34 > 0:13:37Do you want sugar?
0:13:37 > 0:13:41- Sorry?- In your tea. Mum's asking.
0:13:41 > 0:13:44No. Just white, thanks.
0:13:44 > 0:13:46There's only one explanation, as far as I can see.
0:13:46 > 0:13:49- What's that, then? - The graves eat people.
0:13:49 > 0:13:52Devour them whole, leaving no trace.
0:13:52 > 0:13:53Not sure about that.
0:13:53 > 0:13:55They didn't steal the body from above.
0:13:55 > 0:13:57They couldn't have got in from the sides.
0:13:57 > 0:14:00Only other thing is, they get in from underneath.
0:14:00 > 0:14:02Not very likely, though.
0:14:02 > 0:14:04When you've eliminated the impossible,
0:14:04 > 0:14:07whatever remains, however improbable, must be the truth.
0:14:07 > 0:14:10- Sorry?- Sherlock Holmes.
0:14:10 > 0:14:13Got the audiobook.
0:14:13 > 0:14:16The graves round here eat people.
0:14:23 > 0:14:28Is that what happened to Mo? Are they dead?
0:14:28 > 0:14:30It's not quicksand.
0:14:30 > 0:14:33She didn't just sink - something pulled her in, it wanted her.
0:14:33 > 0:14:36The ground wanted her?
0:14:36 > 0:14:40You said the ground was dormant, just a patch of earth, when you first saw it this morning.
0:14:40 > 0:14:44And the drill had been stopped.
0:14:44 > 0:14:45That's right.
0:14:45 > 0:14:48But when you re-started the drill, the ground fought back.
0:14:48 > 0:14:52So what, the ground wants to stop us drilling?!
0:14:52 > 0:14:55Doctor, that is ridiculous.
0:14:57 > 0:15:02I'm not saying that, and it's not ridiculous, I just don't think it's right. Oh! Of course!
0:15:02 > 0:15:04It's bio-programming!
0:15:04 > 0:15:05What?!
0:15:05 > 0:15:09Bio-programming! Oh, clever.
0:15:09 > 0:15:13You use bio-signals to resonate the internal molecular structure of natural objects!
0:15:13 > 0:15:17It's mainly used in engineering and construction, mostly jungle planets,
0:15:17 > 0:15:20but that's way in the future, and not here. What's it doing here?
0:15:20 > 0:15:22Sorry, did you just say jungle planets?
0:15:22 > 0:15:28- You're not making any sense, man! - 'Scuse me, I'm making perfect sense, you're just not keeping up.
0:15:28 > 0:15:33The earth, the ground beneath our feet, was bio-programmed to attack.
0:15:33 > 0:15:37Yeah, even if that were possible, which, by the way, it's not, why?
0:15:37 > 0:15:40Stop you drilling! We find what's doing the bio-programming, find Amy, get her back.
0:15:40 > 0:15:43- Ssh ssh ssh! Have I gone mad?! I've gone mad!- Doctor.
0:15:43 > 0:15:46Ssh ssh! Silence! Absolute silence!
0:15:53 > 0:15:56- You stopped the drill, right?- Yes!
0:15:56 > 0:15:58And you've only got the one drill?
0:15:58 > 0:16:03- Yes! - You're sure about that?- Yes!
0:16:08 > 0:16:09WHIRRING
0:16:09 > 0:16:12So, if you shut the drill down...
0:16:12 > 0:16:14why can I still hear drilling?
0:16:19 > 0:16:21- It's under the ground. - That's not possible.
0:16:24 > 0:16:26Oh, no, what, what are you doing?
0:16:26 > 0:16:29Hacking into your records. Reports, samples, sensors, good,
0:16:29 > 0:16:32just unite the data, make it all one big conversation, let's have a look.
0:16:32 > 0:16:34So. We are here and this is your drill hole.
0:16:34 > 0:16:3821.009 kilometres.
0:16:38 > 0:16:41Well done!
0:16:41 > 0:16:42Thank you. It's taken us a long time.
0:16:42 > 0:16:44Why here, though? Why drill on this site?
0:16:44 > 0:16:48We found patches of grass in this area, containing trace minerals
0:16:48 > 0:16:50unseen in this country for 20 million years.
0:16:50 > 0:16:53The blue grass? Oh, Nasreen,
0:16:53 > 0:16:56those trace minerals weren't X marking the spot, saying dig here.
0:16:56 > 0:16:58They were a warning. Stay away.
0:16:58 > 0:17:02Cos while you've been drilling down...
0:17:02 > 0:17:05somebody else has been drilling up.
0:17:05 > 0:17:09Oh, beautiful.
0:17:09 > 0:17:12Network of tunnels all the way down.
0:17:12 > 0:17:14No, no, we've surveyed that area.
0:17:14 > 0:17:16You only saw what you went looking for.
0:17:16 > 0:17:19What are they?
0:17:19 > 0:17:20Heat signals.
0:17:20 > 0:17:23Wait, dual readings, hot and cold, doesn't make sense.
0:17:23 > 0:17:26And now they're moving.
0:17:26 > 0:17:28Fast. How many people live nearby?
0:17:28 > 0:17:29Just my daughter and her family.
0:17:29 > 0:17:31The rest of the staff travel in.
0:17:31 > 0:17:34Grab this equipment and follow me.
0:17:34 > 0:17:36Why? What're we doing?!
0:17:36 > 0:17:38That noise isn't a drill.
0:17:38 > 0:17:42It's transport. Three of them, 30km down, rate of speed looks about 150km an hour.
0:17:42 > 0:17:47Should be here in... ooh, quite soon, 12 minutes.
0:17:47 > 0:17:52Whatever bio-programmed the Earth is on its way up, now.
0:17:56 > 0:18:01- How can something be coming up when there's only the Earth's crust down there?- You saw the readings!
0:18:01 > 0:18:02Who are you, anyway?!
0:18:02 > 0:18:04How can you know all this?
0:18:05 > 0:18:08Whoa, did you see that?
0:18:10 > 0:18:12No, no, no!
0:18:26 > 0:18:30Energy signal originating from under the Earth. We're trapped.
0:18:31 > 0:18:34Doctor! Something weird's going on here, the graves are eating people.
0:18:34 > 0:18:36Not now, Rory!
0:18:36 > 0:18:38Energy barricade. Invisible to the naked eye.
0:18:38 > 0:18:41We can't get out and no-one from the outside world can get in.
0:18:41 > 0:18:43What?!
0:18:43 > 0:18:45OK, what about the TARDIS?
0:18:45 > 0:18:49- The what?!- No, those energy patterns would play havoc with the circuits.
0:18:49 > 0:18:53With a bit of time, maybe, but we've only got nine and a half minutes.
0:18:53 > 0:18:56Nine and a half minutes to what?
0:18:56 > 0:18:59We're trapped. And something's burrowing towards the surface.
0:19:01 > 0:19:05- Where's Amy? - Get everyone inside the church!
0:19:07 > 0:19:10Rory, I'll get her back.
0:19:10 > 0:19:13- What d'you mean, get her back? Where's she gone?- She was taken.
0:19:13 > 0:19:15Into the Earth.
0:19:15 > 0:19:17How?!
0:19:17 > 0:19:21- Why didn't you stop it?! - I tried. I promise, I tried. - Well, you should've tried harder!
0:19:21 > 0:19:24I'll find Amy. I'll keep you all safe. I promise.
0:19:24 > 0:19:26Come on, please.
0:19:26 > 0:19:28I need you alongside me.
0:19:56 > 0:19:58Where's Mo? Is he with you?
0:20:00 > 0:20:03This flaming' door! Always sticking! I thought you were having it fixed!
0:20:03 > 0:20:05Dad!
0:20:05 > 0:20:08Something's happened to him, hasn't it?
0:20:08 > 0:20:12So we can't get out, we can't contact anyone.
0:20:12 > 0:20:17And something, the something that took my husband, is coming up through the Earth.
0:20:17 > 0:20:19Yes. If we move quickly enough, we can be ready.
0:20:19 > 0:20:22No, stop. This has gone far enough. What is this?
0:20:22 > 0:20:23He's telling the truth, love.
0:20:23 > 0:20:29Come on! It's not the first time we've had no mobile or phone signals. Reception's always rubbish.
0:20:29 > 0:20:33Look, Ambrose, we saw the Doctor's friend get taken, OK? You saw the lightning in the sky.
0:20:33 > 0:20:39I have seen the impossible today, and the only person who's made any sense of it, for me, is the Doctor.
0:20:39 > 0:20:43- Him?!- Me. - Can you get my dad back?
0:20:51 > 0:20:56Yes. But I need you to trust me and do exactly as I say from this second onwards
0:20:56 > 0:20:58because we're running out of time.
0:21:02 > 0:21:04So tell us what to do.
0:21:04 > 0:21:07Thank you. We have eight minutes to set up a line of defence.
0:21:07 > 0:21:11Bring me every phone, camera, every piece of recording or transmitting equipment you can find.
0:21:12 > 0:21:17Every burglar alarm, every movement sensor, every security light.
0:21:17 > 0:21:20I want the whole area covered with sensors.
0:21:24 > 0:21:26Right, we need to be ready for whatever's coming up.
0:21:26 > 0:21:29I need a map of the village, marking where the cameras are going.
0:21:29 > 0:21:31I can't do the words. I'm dyslexic.
0:21:31 > 0:21:33Oh, that's all right, I can't make a decent meringue.
0:21:33 > 0:21:36Draw like your life depends on it, Elliot.
0:21:37 > 0:21:406 minutes 40.
0:21:51 > 0:21:54Works in quadrants, every movement sensor and triplight we've got.
0:21:54 > 0:21:56If anything moves, we'll know.
0:21:56 > 0:21:58Good lad!
0:22:03 > 0:22:07- Oi! What're you doing?!- Resources!
0:22:07 > 0:22:11Every little helps! Meals on wheels.
0:22:11 > 0:22:15What've you got here then, warmer in the front, refrigerated in the back.
0:22:15 > 0:22:18Bit chilly for a hideout, mind.
0:22:18 > 0:22:21- What are those? - Like you say, every little helps.
0:22:21 > 0:22:24No! No weapons. It's not the way I do things.
0:22:24 > 0:22:26You said we're supposed to defend ourselves.
0:22:26 > 0:22:29Oh, Ambrose, you're better than this. I'm asking nicely.
0:22:29 > 0:22:33Put them away.
0:22:45 > 0:22:49Look at that! Perfect!
0:22:49 > 0:22:52Dyslexia never stopped Da Vinci or Einstein, it's not stopping you.
0:22:52 > 0:22:54- I don't understand what you're doing.- Two phase plan.
0:22:54 > 0:22:57First, the sensors and cameras will tell us when something arrives.
0:22:57 > 0:23:02Second, if something does arrive, I use this to send a sonic pulse through that network of devices,
0:23:02 > 0:23:07- a pulse which would temporarily incapacitate most things in the universe.- Knock 'em out. Cool.
0:23:10 > 0:23:13- Lovely place to grow up, round here. - Suppose.
0:23:13 > 0:23:16I want to live in a city one day. Soon as I'm old enough, I'll be off.
0:23:16 > 0:23:19I was the same, where I grew up.
0:23:19 > 0:23:22- Did you get away?- Yeah. - Do you ever miss it?
0:23:25 > 0:23:28So much.
0:23:28 > 0:23:30Is it monsters coming?
0:23:32 > 0:23:34Have you met monsters before?
0:23:34 > 0:23:37- Yeah.- You scared of them?
0:23:37 > 0:23:40No! They're scared of me.
0:23:40 > 0:23:42Will you really get my dad back?
0:23:42 > 0:23:44No question.
0:23:46 > 0:23:47I left my headphones at home.
0:23:59 > 0:24:00How're you doing?
0:24:00 > 0:24:02It's getting darker.
0:24:02 > 0:24:03How can it be getting dark so quickly?
0:24:03 > 0:24:07Shutting out light from within the barricade. Trying to isolate us in the dark.
0:24:07 > 0:24:09Which means...
0:24:09 > 0:24:10RUMBLING
0:24:12 > 0:24:15It's here.
0:24:15 > 0:24:17They're close to the surface now.
0:24:25 > 0:24:27- Tony!- Like you didn't know.
0:24:40 > 0:24:43I can't open it! It keeps sticking! The wood's warped.
0:24:43 > 0:24:46- Any time you want to help(!) - Can't you sonic it?
0:24:46 > 0:24:48- It doesn't do wood!- That is rubbish!
0:24:48 > 0:24:51Oi! Don't diss the sonic!
0:24:57 > 0:24:59See if we can get a fix.
0:25:21 > 0:25:24- No power.- It's deliberate.
0:25:24 > 0:25:26What do we do now?
0:25:26 > 0:25:30Nothing. We've got nothing! They sent an energy surge to wreck our systems.
0:25:30 > 0:25:33Is everyone OK? Is anyone hurt?
0:25:33 > 0:25:36- I'm fine.- Me too.
0:25:36 > 0:25:37RUMBLING
0:25:41 > 0:25:44Doctor, what was that?
0:25:44 > 0:25:47- It's like the holes at the drill station.- Is this how they happened?
0:25:50 > 0:25:54- It's coming through the final layer of Earth.- What is?!
0:25:56 > 0:25:58SILENCE
0:25:58 > 0:26:02The banging's stopped.
0:26:03 > 0:26:05Where's Elliot?
0:26:05 > 0:26:07Has anyone seen Elliot?
0:26:07 > 0:26:09Did he come in?
0:26:09 > 0:26:11Was he in when the door was shut?
0:26:11 > 0:26:13Who counted him back in?
0:26:13 > 0:26:15Who saw him last?
0:26:18 > 0:26:19I did.
0:26:20 > 0:26:22Where is he?
0:26:25 > 0:26:27He said he was going to get headphones.
0:26:27 > 0:26:30And you let him go?
0:26:30 > 0:26:32He was out there on his own?
0:26:55 > 0:26:59Mum! Grandpa Tony! Let me in!
0:26:59 > 0:27:06- Elliot!- Let me in.- He's out there! Help me.- Open the door!
0:27:06 > 0:27:07Mum! There's something out here!
0:27:07 > 0:27:11Push, Elliot, push, Elliot!
0:27:11 > 0:27:14Mum! Hurry up!
0:27:18 > 0:27:20SNARLING
0:27:22 > 0:27:24Mum!
0:27:24 > 0:27:26- Come on!- Elliot!
0:27:28 > 0:27:30Where is he?
0:27:32 > 0:27:38He was here. He was here! Elliot.
0:27:38 > 0:27:41- Ambrose, don't go running off. - Ambrose!
0:27:41 > 0:27:43Elliot! It's Mum!
0:27:53 > 0:27:56No-o-o-o-o-o!
0:28:02 > 0:28:03Get off me!
0:28:12 > 0:28:15- Agh!- Dad!- What happened?
0:28:15 > 0:28:17My dad's hurt.
0:28:17 > 0:28:19Get him into the church now!
0:28:19 > 0:28:23Elliot's gone. They've killed him, haven't they?
0:28:23 > 0:28:24I don't think so.
0:28:24 > 0:28:28They've taken three people, when they could've just killed them up here.
0:28:28 > 0:28:31There's still hope, Ambrose. There is always hope.
0:28:31 > 0:28:36- Then why've they taken him? - I don't know.
0:28:36 > 0:28:41I'll find Elliot, I promise. But first I've got to stop this attack. Please, get inside the church.
0:28:44 > 0:28:48- Come on, Dad.- So, what now?
0:29:22 > 0:29:24Cold blood.
0:29:24 > 0:29:27I know who they are.
0:29:31 > 0:29:33HE WHISTLES
0:29:45 > 0:29:47SCREAMS
0:29:56 > 0:30:00- We got it!- Defending the planet with meals on wheels!
0:30:00 > 0:30:03- RUMBLING - What was that?
0:30:03 > 0:30:05Sounds like they're leaving.
0:30:05 > 0:30:06Without this one?
0:30:08 > 0:30:10Looks like we scared them off!
0:30:10 > 0:30:13I don't think so.
0:30:13 > 0:30:17Now both sides have hostages.
0:30:29 > 0:30:32Let me out! Can anybody hear me?!
0:30:32 > 0:30:34I'm alive in here!
0:30:34 > 0:30:35Let me out!!
0:30:37 > 0:30:39I know you're out there!
0:30:39 > 0:30:43My name is Amy Pond and you'd better get me the hell out of here or so help me
0:30:43 > 0:30:46I am going to kick your backside!
0:30:48 > 0:30:50Please?
0:30:50 > 0:30:52Shh!
0:30:52 > 0:30:54Did you just shush me?!
0:30:54 > 0:30:57DID YOU JUST SHUSH ME?!
0:30:57 > 0:31:00No no no, don't do that. No gas!
0:31:00 > 0:31:02No gas!
0:31:02 > 0:31:04SHE COUGHS
0:31:09 > 0:31:13I've met these creatures before, different branch of the species, but all the same...
0:31:13 > 0:31:15Let's see if our friend's thawed out!
0:31:15 > 0:31:18- Are you sure? By yourself? - Very sure.
0:31:18 > 0:31:22- But the sting...- Venom gland takes at least 24 hours to recharge.
0:31:22 > 0:31:24Am I right?
0:31:25 > 0:31:28I know what I'm doing.
0:31:28 > 0:31:29I'll be fine.
0:31:42 > 0:31:44I'm the Doctor.
0:31:45 > 0:31:47I've come to talk.
0:31:47 > 0:31:50I'm going to remove your mask.
0:32:09 > 0:32:11You are beautiful.
0:32:14 > 0:32:18Remnant of a bygone age on planet Earth.
0:32:18 > 0:32:22And by the way, lovely mode of travel!
0:32:22 > 0:32:25Geothermal currents, projecting you up through a network of tunnels.
0:32:25 > 0:32:29Gorgeous! Mind if I sit? Now.
0:32:29 > 0:32:31Your people
0:32:31 > 0:32:35have a friend of mine.
0:32:39 > 0:32:42I want her back.
0:32:42 > 0:32:47Why did you come to the surface?
0:32:47 > 0:32:49What do you want?
0:32:51 > 0:32:55Oh, I do hate a monologue. Give us a bit back. How many are you?
0:32:55 > 0:32:59- I'm the last of my species.- Really?
0:32:59 > 0:33:03No. "Last of the species", the Klempari Defence.
0:33:03 > 0:33:08As an interrogation defence, it's a bit old hat, I'm afraid.
0:33:08 > 0:33:11I'm the last of my species.
0:33:11 > 0:33:13No. You're really not.
0:33:13 > 0:33:19Because I'm the last of my species and I know how it sits in a heart. So don't insult me.
0:33:22 > 0:33:24Let's start again.
0:33:24 > 0:33:26Tell me your name.
0:33:29 > 0:33:30Alaya.
0:33:30 > 0:33:34How long has your tribe been sleeping under the Earth, Alaya?
0:33:35 > 0:33:37It's not difficult to work out.
0:33:37 > 0:33:40You're 300 million years out of your comfort zone.
0:33:40 > 0:33:42Question is, what woke you now?
0:33:42 > 0:33:44We were attacked.
0:33:44 > 0:33:47The drill.
0:33:47 > 0:33:50Our sensors detected a threat to our life support systems.
0:33:50 > 0:33:53The warrior class was activated to prevent the assault.
0:33:53 > 0:33:56We will wipe the vermin from the surface and reclaim our planet.
0:33:56 > 0:33:58Do we have to say vermin?
0:33:58 > 0:34:00They're really very nice.
0:34:00 > 0:34:02- Primitive apes. - Extraordinary species.
0:34:02 > 0:34:04You attack them, they'll fight back. But!
0:34:04 > 0:34:07There's a peace to be brokered here.
0:34:07 > 0:34:10- I can help you with that. - This land is ours.
0:34:10 > 0:34:12We lived here long before the apes.
0:34:12 > 0:34:15Doesn't give you automatic rights to it now, I'm afraid.
0:34:15 > 0:34:19- Humans won't give up the planet. - So we destroy them.
0:34:19 > 0:34:21- You underestimate them. - You underestimate us.
0:34:21 > 0:34:25One tribe of homo reptilia against six billion humans, you've got your work cut out.
0:34:25 > 0:34:30We did not initiate combat. But we can still win.
0:34:30 > 0:34:32Tell me where my friend is.
0:34:34 > 0:34:36Give us back the people who were taken.
0:34:36 > 0:34:38No.
0:34:46 > 0:34:49I'm not going let you provoke a war, Alaya.
0:34:51 > 0:34:53There'll be no battle here today.
0:34:53 > 0:34:56The fire of war is already lit. A massacre is due.
0:34:58 > 0:35:00Not while I'm here.
0:35:00 > 0:35:05I'll gladly die for my cause. What will you sacrifice for yours?
0:35:11 > 0:35:12You're going to what?!
0:35:12 > 0:35:18I'm going to go down below the surface, to find the rest of the tribe. To talk to them.
0:35:18 > 0:35:22- You're going to negotiate with these aliens?- They're not aliens!
0:35:22 > 0:35:25They're Earth...liens!
0:35:25 > 0:35:32Once known as the Silurian race, or, some would argue, Eocenes, or Homo reptilia.
0:35:32 > 0:35:34Not monsters, not evil.
0:35:34 > 0:35:37Well, only as evil as you are.
0:35:37 > 0:35:40The previous owners of the planet, that's all.
0:35:40 > 0:35:44Look, from their point of view, you're the invaders.
0:35:44 > 0:35:47Your drill was threatening their settlement.
0:35:49 > 0:35:51Now, the creature in the crypt.
0:35:55 > 0:35:58Her name's Alaya.
0:35:58 > 0:36:01She's one of their warriors and she's my best bargaining chip.
0:36:01 > 0:36:04I need her alive. If she lives, so do Elliot and Mo and Amy.
0:36:04 > 0:36:08Because I will find them.
0:36:12 > 0:36:14While I'm gone,
0:36:14 > 0:36:21you four people, in this church, in this corner of planet Earth,
0:36:21 > 0:36:25you have to be the best of humanity.
0:36:25 > 0:36:28What if they come back?! Shouldn't we be examining this creature,
0:36:28 > 0:36:32- dissecting it, finding its weak points?- No dissecting! No examining!
0:36:32 > 0:36:35We return their hostage, they return ours. Nobody gets harmed.
0:36:35 > 0:36:37We can land this, together.
0:36:37 > 0:36:40If you are the best you can be.
0:36:45 > 0:36:47You are decent,
0:36:47 > 0:36:50brilliant people.
0:36:52 > 0:36:53Nobody dies today.
0:36:57 > 0:36:58Understand?
0:37:11 > 0:37:13No, sorry, no, what're you doing?
0:37:13 > 0:37:17Coming with you, of course! What is it, some kind of transport pod?
0:37:17 > 0:37:20Sort of, but you're not... coming with me!
0:37:20 > 0:37:22He's right, you're not.
0:37:22 > 0:37:25I have spent all my life excavating the layers of this planet.
0:37:25 > 0:37:28And now you want me to stand back while you head down into it?
0:37:28 > 0:37:31- I don't think so! - I don't have time to argue! - I thought we were in a rush.
0:37:31 > 0:37:34- It'll be dangerous. - Oh, so's crossing the road.
0:37:34 > 0:37:36Oh, for goodness' sake, all right, then! Come on!
0:37:41 > 0:37:43- Come back safe.- Of course.
0:37:49 > 0:37:52Welcome aboard the TARDIS. Now don't touch anything!
0:37:52 > 0:37:54Very precious.
0:37:54 > 0:37:57No way!
0:37:57 > 0:37:59But that's...
0:38:00 > 0:38:01this is...
0:38:03 > 0:38:05fantastic!
0:38:05 > 0:38:12- What does it do?- Everything! I'm hoping, if we're going down, that barricade won't interfere.
0:38:12 > 0:38:16- Did you touch something?! - No! Isn't this what it does?! - I'm not doing anything!
0:38:16 > 0:38:20We've been hijacked! I can't stop it!
0:38:20 > 0:38:22They must've sensed the electro-magnetic field!
0:38:28 > 0:38:31They're pulling the TARDIS down into the Earth!
0:38:34 > 0:38:36You had to come and see me.
0:38:36 > 0:38:40We are going to keep you safe.
0:38:40 > 0:38:45Your tribe are going to give us back our people, in exchange for you.
0:38:45 > 0:38:47No.
0:38:52 > 0:38:57Shall I tell you what's really going to happen, apes?
0:38:57 > 0:38:59One of you will kill me.
0:38:59 > 0:39:01My death shall ignite a war.
0:39:01 > 0:39:06And every stinking ape shall be wiped from the surface of my beloved planet.
0:39:06 > 0:39:10- We won't allow that to happen. - I know apes better than you know yourselves.
0:39:12 > 0:39:15I know which one of you will kill me.
0:39:15 > 0:39:17Do you?
0:39:42 > 0:39:45- Whoa!- Whoa!
0:39:54 > 0:39:56- Oi.- Where are we?
0:40:09 > 0:40:11HE WHISTLES
0:40:11 > 0:40:15Looks like we fell through the bottom of their tunnel system.
0:40:15 > 0:40:19- Don't suppose it was designed for handling something like this. - How far down are we?
0:40:19 > 0:40:22A lot more than 21km.
0:40:22 > 0:40:24So why aren't we burning alive?
0:40:24 > 0:40:28Don't know. Interesting, isn't it?
0:40:28 > 0:40:30It's like this is everyday to you!
