0:00:02 > 0:00:04Close your eyes and tell me what you see.
0:00:10 > 0:00:11The Library.
0:00:18 > 0:00:21Open your eyes again.
0:00:21 > 0:00:23Where are you now?
0:00:23 > 0:00:25My living room, Dr Moon.
0:00:25 > 0:00:27When you close your eyes...
0:00:27 > 0:00:29I go to the Library.
0:00:31 > 0:00:34Go to the Library now.
0:00:35 > 0:00:38- Are you back there?- Yes.
0:00:38 > 0:00:40The same part?
0:00:40 > 0:00:42No, it's always different.
0:00:42 > 0:00:45The Library goes on for ever.
0:00:45 > 0:00:48How you do move around?
0:00:48 > 0:00:50By wishing.
0:00:50 > 0:00:52HAMMERING ON DOOR
0:00:53 > 0:00:55- What's wrong?- Something's here!
0:00:55 > 0:00:58Someone's got in! No-one's supposed to get in!
0:00:58 > 0:01:01She's never mentioned anyone else. She's always been alone.
0:01:01 > 0:01:04Someone's in my library.
0:01:04 > 0:01:06No! No, please! That's not allowed!
0:01:06 > 0:01:09Listen to me.
0:01:09 > 0:01:11The Library is in your mind.
0:01:11 > 0:01:14I know it's in my mind. But something's got inside!
0:01:25 > 0:01:27Oh! Hello!
0:01:27 > 0:01:30Sorry to burst in on you like this.
0:01:30 > 0:01:31OK if we stop here for a bit?
0:02:10 > 0:02:15Books! People never really stop loving books.
0:02:16 > 0:02:1851st century.
0:02:18 > 0:02:22By now you've got holovids, direct to brain downloads, fiction mist,
0:02:22 > 0:02:26but you need the smell. The smell of books, Donna. Deep breath.
0:02:30 > 0:02:32The Library.
0:02:33 > 0:02:35So big it doesn't need a name.
0:02:35 > 0:02:37Just a great big "the."
0:02:37 > 0:02:38It's like a city.
0:02:38 > 0:02:41It's a world. Literally a world.
0:02:41 > 0:02:44The core of the planet is the index computer, biggest hard drive ever.
0:02:44 > 0:02:47And up here, every book ever written.
0:02:47 > 0:02:53Whole continents of Jeffrey Archer, Bridget Jones, Monty Python's Big Red Book.
0:02:53 > 0:02:55Brand new editions, specially printed.
0:02:58 > 0:03:00We're near the equator, so...
0:03:01 > 0:03:04..this must be Biographies!
0:03:04 > 0:03:06I love biographies.
0:03:06 > 0:03:08Yeah, very you. Always a death at the end.
0:03:08 > 0:03:11You need a good death. Without death, there'd only be comedies.
0:03:11 > 0:03:14Dying gives us size. Oi!
0:03:14 > 0:03:16- Spoilers!- What?
0:03:16 > 0:03:20These books are from your future. Don't read ahead - spoil all the surprises.
0:03:20 > 0:03:25- Like peeking at the end.- Isn't travelling with you one big spoiler?
0:03:25 > 0:03:28I try to keep you away from major plot developments.
0:03:28 > 0:03:31Which, to be honest, I seem to be very bad at,
0:03:31 > 0:03:35cos you know what? This is the biggest library in the universe.
0:03:37 > 0:03:38So where is everyone?
0:03:42 > 0:03:46- It's silent.- The Library?
0:03:49 > 0:03:52The planet.
0:03:52 > 0:03:55The whole planet.
0:03:56 > 0:03:58Maybe it's a Sunday.
0:03:58 > 0:04:01No, I never land on Sundays.
0:04:01 > 0:04:03- Sundays are boring.- Well...
0:04:03 > 0:04:08Maybe everyone's really, really quiet.
0:04:08 > 0:04:09Yeah, maybe.
0:04:09 > 0:04:12But they'd still show up on the system.
0:04:12 > 0:04:15Doctor, why are we here? Really, why?
0:04:15 > 0:04:17Oh, you know, just passing.
0:04:17 > 0:04:19No, seriously.
0:04:19 > 0:04:22It was all, "Let's hit the beach," then suddenly we're in a library.
0:04:22 > 0:04:24- Why?- Now, that's interesting.
0:04:24 > 0:04:27- What?- Scanning for life forms.
0:04:27 > 0:04:29If I do a scan looking for your basic humanoids -
0:04:29 > 0:04:33your book readers, few limbs and a face - apart from us, I get nothing.
0:04:33 > 0:04:35Zippo, nada, see?
0:04:35 > 0:04:40Nobody home. But if I widen the parameters to any kind of life...
0:04:44 > 0:04:47A million million.
0:04:47 > 0:04:48Gives up after that.
0:04:50 > 0:04:53A million million.
0:04:53 > 0:04:55But there's nothing here.
0:04:55 > 0:04:58There's no-one.
0:04:58 > 0:05:00And not a sound.
0:05:02 > 0:05:05A million million life forms
0:05:05 > 0:05:07and silence in the Library.
0:05:08 > 0:05:11But there's no-one here.
0:05:11 > 0:05:14There's just books. I mean, it's not the books, is it?
0:05:14 > 0:05:16I mean, it can't be the books, can it?
0:05:16 > 0:05:18I mean, books can't be alive?
0:05:29 > 0:05:31Welcome!
0:05:34 > 0:05:36- That came from in there, yeah.- Yeah!
0:05:50 > 0:05:54I am Courtesy Node 710/aqua.
0:05:54 > 0:05:58Please enjoy the Library and respect the personal access codes
0:05:58 > 0:06:03of all your fellow readers regardless of species or hygiene taboo.
0:06:03 > 0:06:05That face, it looks real.
0:06:05 > 0:06:07Yeah, don't worry about it.
0:06:07 > 0:06:09But a statue with a real face, though!
0:06:09 > 0:06:11It's a hologram, isn't it?
0:06:11 > 0:06:12No, but really, it's fine.
0:06:12 > 0:06:17There follows a brief message from the head librarian for your urgent attention.
0:06:17 > 0:06:24It has been edited for tone and content by a Felman Lux Automated Decency Filter.
0:06:24 > 0:06:27Message follows. "Run.
0:06:27 > 0:06:29"For God's sake, run.
0:06:29 > 0:06:31"Nowhere is safe.
0:06:31 > 0:06:37"The Library has sealed itself, we can't... Oh, they're here.
0:06:37 > 0:06:41"Arg. Slarg. Snick." Message ends.
0:06:41 > 0:06:46Please switch off your mobile comm units for the comfort of other readers.
0:06:46 > 0:06:49So that's why we're here.
0:06:49 > 0:06:53- Any other messages, same date stamp? - One additional message.
0:06:53 > 0:06:57This message carries a Felman Lux coherency warning of 5, 0, 11...
0:06:57 > 0:06:59Yeah, yeah, fine, just play it.
0:06:59 > 0:07:01Message follows.
0:07:01 > 0:07:04"Count the shadows.
0:07:04 > 0:07:05"For God's sake, remember...
0:07:05 > 0:07:08"if you want to live, count the shadows."
0:07:08 > 0:07:10Message ends.
0:07:14 > 0:07:16Donna...
0:07:16 > 0:07:19Yeah?
0:07:19 > 0:07:21Stay out of the shadows.
0:07:23 > 0:07:25Why, what's in the shadows?
0:07:43 > 0:07:45So...
0:07:45 > 0:07:47We weren't just in the neighbourhood.
0:07:47 > 0:07:50Yeah, I kind of, sort of lied a bit.
0:07:50 > 0:07:53I got a message on the psychic paper.
0:07:54 > 0:07:57What do you think - cry for help?
0:07:57 > 0:08:01Cry for help with a kiss?
0:08:01 > 0:08:03Oh, we've all done that.
0:08:03 > 0:08:05- Who's it from?- No idea.
0:08:05 > 0:08:09- So why did we come here, why did you..?- Donna.
0:08:09 > 0:08:11BUZZING
0:08:11 > 0:08:15- What's happening?- Run!
0:08:15 > 0:08:18- What, is it locked? - Jammed! The wood's warped!
0:08:19 > 0:08:22Sonic it, use the thingy!
0:08:22 > 0:08:25- I can't, it's wood! - What, it doesn't do wood?!
0:08:25 > 0:08:27If I can vibrate the molecules, fry the bindings,
0:08:27 > 0:08:31- I can shatterline the interface. - Oh, get out of the way!
0:08:40 > 0:08:42Oh! Hello!
0:08:42 > 0:08:46Sorry to burst in on you like this. OK if we stop here for a bit?
0:08:48 > 0:08:52What is it?
0:08:52 > 0:08:55Security camera.
0:08:55 > 0:08:57Switched itself off.
0:09:00 > 0:09:05- They were in my library. How can they be in my library? - Who were they?
0:09:05 > 0:09:09- SONIC SCREWDRIVER WHIRRS - What's that? What's that noise? - What noise?
0:09:11 > 0:09:13Nice door skills, Donna.
0:09:13 > 0:09:15Yeah, well, you know, boyfriends...
0:09:15 > 0:09:19sometimes you need the element of surprise. What was that,
0:09:19 > 0:09:23what was after us? I mean, did we just run away from a power cut?
0:09:23 > 0:09:24Possibly.
0:09:27 > 0:09:31- Are we safe here?- Course we're safe. There's a little shop.
0:09:37 > 0:09:39Gotcha!
0:09:41 > 0:09:45No, stop it, no, no!
0:09:47 > 0:09:49Ooh, I'm sorry.
0:09:49 > 0:09:53I really am, I'm sorry, I'm so sorry. It's alive.
0:09:53 > 0:09:55You said it was a security camera.
0:09:55 > 0:09:57It is.
0:09:57 > 0:09:59It's an alive one.
0:09:59 > 0:10:01Can you hear me?
0:10:01 > 0:10:03Are you all right?
0:10:06 > 0:10:10- Others are coming. - Who's coming? Who are the others?
0:10:10 > 0:10:12The Library is breached.
0:10:12 > 0:10:15- Others are coming.- What others?
0:10:15 > 0:10:18Others? What does it mean, "others"?
0:10:22 > 0:10:24Excuse me, what does it mean, "others"?
0:10:24 > 0:10:28That's barely more than a speak your weight machine, it can't help you.
0:10:28 > 0:10:29So why's it got a face?
0:10:29 > 0:10:35This flesh aspect was donated by Mark Chambers on the occasion of his death.
0:10:35 > 0:10:37It's a real face?
0:10:37 > 0:10:40It has been actualised individually for you
0:10:40 > 0:10:44from the many facial aspects saved to our extensive flesh banks.
0:10:44 > 0:10:46Please enjoy.
0:10:46 > 0:10:50It chose me a dead face it thought I'd like? That statue's got a real dead person's face on it!
0:10:50 > 0:10:53It's the 51st century.
0:10:53 > 0:10:55That's basically like donating a park bench.
0:10:55 > 0:10:58It's donating a face!
0:10:58 > 0:10:59No, wait, no!
0:10:59 > 0:11:02- Oi! Hands!- The shadow, look.
0:11:04 > 0:11:08- What about it?- Count the shadows.
0:11:08 > 0:11:12One. There, I counted it, one shadow.
0:11:12 > 0:11:16Yeah... But what's casting it?
0:11:26 > 0:11:29Oh! I'm thick! Look at me, I'm old and thick!
0:11:29 > 0:11:32Head's too full of stuff, I need a bigger head!
0:11:33 > 0:11:36BUZZING
0:11:36 > 0:11:37Power must be going.
0:11:37 > 0:11:40This place runs on fission cells. They'll outburn the sun.
0:11:40 > 0:11:43- Then why's it dark?- It's not dark.
0:11:47 > 0:11:49That shadow.
0:11:49 > 0:11:51It's gone.
0:11:51 > 0:11:54- We need to get back to the TARDIS. - Why?
0:11:54 > 0:11:56Because that shadow hasn't gone. It's moved.
0:11:56 > 0:12:01Reminder - the Library has been breached, others are coming.
0:12:01 > 0:12:05Reminder - the Library has been breached, others are coming.
0:12:05 > 0:12:08Reminder - the Library has been breached...
0:12:29 > 0:12:31Hello, sweetie.
0:12:31 > 0:12:33- Get out.- Doctor?
0:12:33 > 0:12:35Get back in your rocket and fly away.
0:12:35 > 0:12:39Tell your grandchildren you came to the Library and lived, they won't believe you.
0:12:39 > 0:12:42Pop your helmets, everyone. We've got breathers.
0:12:42 > 0:12:46- How do you know they're not androids?- Cos I've dated androids.
0:12:46 > 0:12:47- They're rubbish.- Who is this?
0:12:47 > 0:12:51You said we were the only expedition, I paid for exclusives.
0:12:51 > 0:12:56- I lied, I'm always lying. Bound to be others.- Miss Evangelista, I want to see the contracts.
0:12:56 > 0:12:58You came through the north door? Much damage?
0:12:58 > 0:13:03Please, just leave. I'm asking you seriously and properly, just lea... Did you say expedition?
0:13:03 > 0:13:05My expedition, I funded it.
0:13:05 > 0:13:09Oh, you're not, are you? Tell me you're not archaeologists.
0:13:09 > 0:13:11Got a problem with archaeologists?
0:13:11 > 0:13:16- I'm a time traveller. I point and laugh at archaeologists.- Ah!
0:13:16 > 0:13:18Professor River Song, archaeologist.
0:13:18 > 0:13:20Lovely name. As you're leaving,
0:13:20 > 0:13:22you need to set up a quarantine beacon.
0:13:22 > 0:13:27Code-wall the planet, the whole planet. Nobody comes here, not ever again.
0:13:27 > 0:13:30- Stop right there! What's your name?- Anita.
0:13:30 > 0:13:32Anita, stay out of the shadows.
0:13:32 > 0:13:35Not a finger in the shadows till you're safely back in your ship.
0:13:35 > 0:13:40Stay in the light. Find a nice, bright spot and just stand.
0:13:40 > 0:13:43If you understand me, look very, very scared.
0:13:48 > 0:13:51No, bit more scared than that.
0:13:53 > 0:13:56- OK, do for now. You, who are you? - Er, Dave.- OK, Dave...
0:13:56 > 0:14:03Oh, well Other Dave, because that's Proper Dave the pilot, he was the first Dave, so when we...
0:14:03 > 0:14:06- The way you came, does it look the same as before?- Yeah.
0:14:06 > 0:14:07Oh, it's a bit darker.
0:14:07 > 0:14:12- How much darker?- I could see where we came through just a moment ago. I can't now.
0:14:12 > 0:14:14Seal the door.
0:14:14 > 0:14:17We're not looking for a way out. Miss Evangelista?
0:14:17 > 0:14:20I'm Mr Lux's personal...everything.
0:14:20 > 0:14:24Sign these contracts agreeing that your experiences inside the Library
0:14:24 > 0:14:29are the intellectual property of the Felman Lux Corporation.
0:14:29 > 0:14:32- Right, give it here. - Yeah, lovely. Thanks.
0:14:33 > 0:14:36My family built this library. I have rights.
0:14:36 > 0:14:40You have a mouth that won't stop. You think there's danger here?
0:14:40 > 0:14:44Something came to this library and killed everything in it, killed a whole world.
0:14:44 > 0:14:46- Danger? Could be. - That was 100 years ago.
0:14:46 > 0:14:50The Library's been silent for 100 years. Whatever came here is long dead.
0:14:50 > 0:14:51Bet your life?
0:14:51 > 0:14:53Always.
0:14:53 > 0:14:56What are you doing?
0:14:56 > 0:14:58- He said seal the door.- Torch!
0:14:58 > 0:15:00You're taking orders from him?
0:15:00 > 0:15:01Spooky, isn't it?
0:15:10 > 0:15:15Almost every species in the universe has an irrational fear of the dark.
0:15:15 > 0:15:20But they're wrong. Cos it's not irrational.
0:15:20 > 0:15:22It's Vashta Nerada.
0:15:22 > 0:15:24What's Vashta Nerada?
0:15:24 > 0:15:27It's what's in the dark.
0:15:27 > 0:15:29It's what's always in the dark.
0:15:31 > 0:15:34- Lights! You got lights?- What for?
0:15:34 > 0:15:38- Form a circle, safe area, big as you can, lights pointing out.- Oi!
0:15:38 > 0:15:40- Do as he says. - You're not listening to him?!
0:15:40 > 0:15:42Apparently, I am. Unpack the lights.
0:15:42 > 0:15:45Other Dave, make sure the door's secure, then help Anita.
0:15:45 > 0:15:48Mr Lux, put your helmet back on, block the visor.
0:15:48 > 0:15:51Proper Dave, I want you to access the library database,
0:15:51 > 0:15:56see what you can find about what happened here a hundred years ago. Pretty Boy, you're with me.
0:15:56 > 0:15:58Step into my office.
0:15:58 > 0:16:01Professor Song, why am I the only one wearing my helmet?
0:16:01 > 0:16:04I don't fancy you.
0:16:04 > 0:16:06Probably, I can help you.
0:16:06 > 0:16:08Pretty Boy, with me, I said.
0:16:12 > 0:16:14- Oh, I'm Pretty Boy?- Yes.
0:16:14 > 0:16:16Ooh, that came out a bit quick!
0:16:16 > 0:16:19Pretty?!
0:16:19 > 0:16:21Don't let your shadows cross!
0:16:21 > 0:16:24Seriously, don't even let them touch.
0:16:24 > 0:16:27- Any of them could be infected. - How can a shadow be infected?
0:16:27 > 0:16:28Can I help?
0:16:28 > 0:16:30- No, we're fine.- I could just...
0:16:30 > 0:16:32you know, hold things.
0:16:32 > 0:16:35Really, we're OK.
0:16:41 > 0:16:43Couldn't she help?
0:16:43 > 0:16:45I just spent four days on a ship with that woman. She's...
0:16:45 > 0:16:49Couldn't tell the difference between the escape pod and the bathroom.
0:16:49 > 0:16:51We had to go back for her.
0:16:51 > 0:16:53Twice.
0:17:05 > 0:17:08- Thanks.- For what? - The usual. For coming when I call.
0:17:08 > 0:17:10That was you?
0:17:10 > 0:17:14You're doing a good job, acting like you don't know me. I assume there's a reason.
0:17:14 > 0:17:18- A fairly good one, actually. - OK, shall we do diaries, then?
0:17:18 > 0:17:19Where are we this time?
0:17:19 > 0:17:24Going by your face, I'd say it's early days for you, yeah? So, erm...
0:17:24 > 0:17:27Crash of the Byzantium... have we done that yet?
0:17:29 > 0:17:32Obviously ringing no bells.
0:17:32 > 0:17:37Right, Picnic at Asgard.
0:17:37 > 0:17:39Have we done Asgard yet?
0:17:41 > 0:17:43Obviously not.
0:17:43 > 0:17:46Blimey, very early days, then. Hoo!
0:17:46 > 0:17:49Life with a time traveller - never knew it could be such hard work.
0:17:54 > 0:17:55Look at you!
0:17:58 > 0:18:01- You're young. - I'm really not, you know.
0:18:01 > 0:18:02No, but you are.
0:18:03 > 0:18:05Your eyes.
0:18:07 > 0:18:10You're younger than I've ever seen you.
0:18:11 > 0:18:14You've seen me before, then?
0:18:16 > 0:18:18Doctor...
0:18:18 > 0:18:21please tell me you know who I am?
0:18:22 > 0:18:24Who are you?
0:18:30 > 0:18:33BEEPING
0:18:33 > 0:18:38Sorry, that was me. Trying to get through into the security protocols, I seem to have set something off.
0:18:38 > 0:18:42- What is that, is that an alarm? - Doctor.
0:18:42 > 0:18:44Doctor, that sounds like...
0:18:44 > 0:18:45It is. It's a phone!
0:18:45 > 0:18:51PHONE RINGING
0:19:02 > 0:19:04Dad!
0:19:04 > 0:19:07In a minute.
0:19:07 > 0:19:10PHONE CONTINUES RINGING
0:19:10 > 0:19:14I'm trying to call up the data core, but it's not responding.
0:19:14 > 0:19:17- Just that noise.- But it's a phone!
0:19:17 > 0:19:19Let me try something.
0:19:19 > 0:19:21PHONE CONTINUES RINGING
0:19:21 > 0:19:25Dad! The phone, aren't you going to answer it?
0:19:25 > 0:19:27It's not ringing, sweetie.
0:19:27 > 0:19:31PHONE CONTINUES RINGING
0:19:41 > 0:19:44OK, doesn't like that, let's try something else.
0:19:55 > 0:19:56'OK, here it comes.'
0:19:59 > 0:20:01Hello?
0:20:01 > 0:20:05Hello. Are you in my television?
0:20:05 > 0:20:08Well, no, I'm...
0:20:08 > 0:20:14I'm sort of in space. I was trying to call up the data core of a triple-grid security processor.
0:20:14 > 0:20:16Would you like to speak to my dad?
0:20:16 > 0:20:19Your dad or your mum, that would be lovely.
0:20:21 > 0:20:23I know you! You were in my library.
0:20:23 > 0:20:25YOUR library?
0:20:25 > 0:20:28The Library's never been on the television before.
0:20:28 > 0:20:35- What have you done?- Ah, I... I just rerouted the interface...
0:20:35 > 0:20:39What happened. Who was that?
0:20:50 > 0:20:53I need another terminal. Keep working on those lights, we need those lights!
0:20:53 > 0:20:57You heard him, people, let there be light.
0:21:11 > 0:21:16- Sorry. You're not allowed to see inside the book, it's against the rules.- What rules?
0:21:16 > 0:21:18Your rules.
0:21:45 > 0:21:47What's that?
0:21:49 > 0:21:52- I didn't do that, did you do that? - Not me.
0:21:55 > 0:21:57What's CAL?
0:22:16 > 0:22:18You all right?
0:22:18 > 0:22:21What's that? What's happening?
0:22:21 > 0:22:22I don't know.
0:22:22 > 0:22:24Oh, thanks for...you know...
0:22:24 > 0:22:26offering to help with the lights.
0:22:28 > 0:22:32They don't want me. They think I'm stupid cos I'm pretty.
0:22:32 > 0:22:34Course they don't, nobody thinks that.
0:22:34 > 0:22:38No, they're right though. I'm a moron, me.
0:22:38 > 0:22:42My dad said I have the IQ of plankton. And I was pleased.
0:22:42 > 0:22:44See, that's funny.
0:22:46 > 0:22:50No, I really was pleased.
0:22:50 > 0:22:52- Is that funny?- No, no.
0:22:55 > 0:22:59What's causing that? Is it the little girl?
0:22:59 > 0:23:00But who is the little girl?
0:23:00 > 0:23:02What's she got to do with this place?
0:23:07 > 0:23:09How does the data core work? What's the principle?
0:23:09 > 0:23:12- What's CAL?- Ask Mr Lux.
0:23:12 > 0:23:14CAL, what is it?
0:23:14 > 0:23:18Sorry. You didn't sign your Personal Experience contracts.
0:23:18 > 0:23:20Mr Lux,
0:23:20 > 0:23:24right now, you're in more danger than you've ever been in your whole life.
0:23:24 > 0:23:26And you're protecting a patent?
0:23:26 > 0:23:29I'm protecting my family's pride.
0:23:29 > 0:23:31Well, funny thing, Mr Lux,
0:23:31 > 0:23:34I don't want to see everyone in this room dead
0:23:34 > 0:23:38because some idiot thinks his pride is more important.
0:23:38 > 0:23:42Then why don't you sign his contract?
0:23:43 > 0:23:47I didn't either. I'm getting worse than you.
0:23:49 > 0:23:52Let's start at the beginning. What happened here?
0:23:52 > 0:23:56On the actual day, a hundred years ago, what physically happened?
0:23:59 > 0:24:03There was a message from the library. Just one.
0:24:03 > 0:24:09"The lights are going out". Then the computer sealed the planet and there was nothing for a hundred years.
0:24:09 > 0:24:14It's taken three generations of my family just to decode the seals and get back in.
0:24:14 > 0:24:17- Um...excuse me...- Not just now.
0:24:19 > 0:24:22There was one other thing in the last message...
0:24:22 > 0:24:24- That's confidential. - I trust this man.
0:24:24 > 0:24:26With my life, with everything.
0:24:26 > 0:24:30- You've only just met him. - No, he's only just met me.- Erm.
0:24:32 > 0:24:34This might be important actually...
0:24:34 > 0:24:36In a moment!
0:24:38 > 0:24:41This is a data extract that came with the message.
0:24:41 > 0:24:444022 saved. No survivors.
0:24:46 > 0:24:514022, that's the exact number of people who were in the Library when the planet was sealed.
0:24:51 > 0:24:55But how can 4022 people have been saved if there were no survivors?
0:24:55 > 0:24:57That's what we're here to find out.
0:24:57 > 0:25:01And so far, what we haven't found, are any bodies.
0:26:06 > 0:26:08SHE SCREAMS
0:26:19 > 0:26:22Everybody, careful. Stay in the light.
0:26:22 > 0:26:24- So you keep saying. I don't see the point!- Who screamed?
0:26:24 > 0:26:28- Miss Evangelista.- Where is she?
0:26:28 > 0:26:30Miss Evangelista, please state your current...
0:26:30 > 0:26:32RADIO ECHOES
0:26:36 > 0:26:39Please state your current...
0:26:39 > 0:26:41position.
0:26:52 > 0:26:54It's her.
0:26:57 > 0:26:59It's Miss Evangelista.
0:26:59 > 0:27:01We heard her scream a few seconds ago.
0:27:01 > 0:27:03What could do that to a person in a few seconds?
0:27:03 > 0:27:05- It took less than a few seconds. - What did?
0:27:05 > 0:27:07"Hello?"
0:27:07 > 0:27:09Erm, I'm sorry everyone,
0:27:09 > 0:27:13this isn't going to be pleasant.
0:27:13 > 0:27:16- She's ghosting.- She's what?
0:27:16 > 0:27:19"Hello, excuse me?"
0:27:19 > 0:27:22"I'm sorry, hello, excuse me?"
0:27:22 > 0:27:24That's...
0:27:24 > 0:27:26That's Miss Evangelista!
0:27:26 > 0:27:29I don't want to sound horrible, but couldn't we...you know?
0:27:29 > 0:27:31This is her last moment... no, we can't.
0:27:31 > 0:27:34A little respect, thank you.
0:27:34 > 0:27:36"Sorry, where am I? Excuse me?"
0:27:36 > 0:27:38But that's Miss Evangelista.
0:27:38 > 0:27:42It's a Data Ghost, she'll be gone in a moment.
0:27:42 > 0:27:46Miss Evangelista, you're fine, just relax.
0:27:46 > 0:27:48We'll be with you presently.
0:27:48 > 0:27:50What's a Data Ghost?
0:27:50 > 0:27:53There's a neural relay in the communicator.
0:27:53 > 0:27:57Let's you send thought mails. That's it there, those green lights.
0:27:57 > 0:28:03Sometimes it can hold an impression of a living consciousness for a short time after death.
0:28:03 > 0:28:05Like an after image.
0:28:06 > 0:28:09My grandfather lasted a day.
0:28:09 > 0:28:12Kept talking about his shoelaces.
0:28:13 > 0:28:15She's in there!
0:28:15 > 0:28:19"I can't see, I can't... Where am I?"
0:28:19 > 0:28:21She's just brain waves now. The pattern won't hold for long.
0:28:23 > 0:28:27She's conscious! She's thinking.
0:28:27 > 0:28:29"I can't see, I can't..."
0:28:29 > 0:28:33- "I don't know what I'm thinking." - She's a footprint on the beach.
0:28:33 > 0:28:34And the tide's coming in.
0:28:34 > 0:28:37"Where's that woman?"
0:28:37 > 0:28:40"The nice woman... is she there?"
0:28:40 > 0:28:45- What woman?- She means...
0:28:45 > 0:28:47I think she means me.
0:28:47 > 0:28:51"Is she there? The nice woman?"
0:28:51 > 0:28:54Yeah, she's here, hang on.
0:28:56 > 0:28:58Go ahead. She can hear you.
0:28:58 > 0:28:59"Hello? Are you there?"
0:29:01 > 0:29:02Help her.
0:29:02 > 0:29:05- She's dead.- Yeah. Help her.
0:29:06 > 0:29:10"Hello? Is that the nice woman?"
0:29:10 > 0:29:12Yeah. Hello.
0:29:12 > 0:29:15Yeah, I'm I'm... I'm here. You OK?
0:29:16 > 0:29:18"What I said before...
0:29:18 > 0:29:20"about being stupid...
0:29:20 > 0:29:22"don't tell the others, they'll only laugh."
0:29:22 > 0:29:24Course I won't.
0:29:24 > 0:29:25Course I won't tell them.
0:29:25 > 0:29:28"Don't tell the others, they'll only laugh..."
0:29:28 > 0:29:31I won't tell them.
0:29:31 > 0:29:32I said I won't.
0:29:32 > 0:29:35"Don't tell the others, they'll only laugh."
0:29:35 > 0:29:38I'm not going to tell them.
0:29:38 > 0:29:39"Don't tell the others, they'll only laugh."
0:29:39 > 0:29:42She's looping now. The pattern's degrading.
0:29:42 > 0:29:45"I can't think, I...don't know, I...
0:29:46 > 0:29:48"I...
0:29:48 > 0:29:49"I...
0:29:49 > 0:29:51"Ice cream.
0:29:51 > 0:29:55"Ice cream. Ice cream.
0:29:55 > 0:29:57"Ice cream."
0:29:57 > 0:29:59Does anybody mind if I..?
0:30:05 > 0:30:07SWITCH CLICKS
0:30:10 > 0:30:15That was horrible. That was the most horrible thing I've ever seen.
0:30:17 > 0:30:19No. It's just a freak of technology.
0:30:21 > 0:30:23But whatever did this to her,
0:30:23 > 0:30:26whatever killed her...
0:30:26 > 0:30:28I'd like a word with that.
0:30:28 > 0:30:29I'll introduce you.
0:30:39 > 0:30:41- I'm going to need a packed lunch. - Hang on.
0:30:44 > 0:30:47- What's in that book?- Spoilers.
0:30:47 > 0:30:49Who are you?
0:30:49 > 0:30:51Professor River Song, University of...
0:30:51 > 0:30:53- To me. Who are you to me?- Again...
0:30:53 > 0:30:56spoilers.
0:30:56 > 0:30:58Chicken, and a bit of salad.
0:30:58 > 0:31:00Knock yourself out.
0:31:03 > 0:31:05Right, you lot.
0:31:05 > 0:31:06Let's meet the Vashta Nerada!
0:31:12 > 0:31:17Darling, Dr Moon is going now. But he'd like a word with you alone, is that all right?
0:31:17 > 0:31:19- Yes, of course, Dr Moon.- Thank you.
0:31:23 > 0:31:26Now, listen.
0:31:27 > 0:31:29This is important.
0:31:29 > 0:31:35There's the real world, and there's the world of nightmares.
0:31:35 > 0:31:37Isn't there? You understand?
0:31:37 > 0:31:39Yes, I know, Dr Moon.
0:31:39 > 0:31:42What I want you to remember is this...
0:31:42 > 0:31:44and I know it's hard.
0:31:44 > 0:31:47The real world is a lie,
0:31:47 > 0:31:50and your nightmares are real.
0:31:50 > 0:31:51The Library is real.
0:31:51 > 0:31:57There are people trapped in there, people who need to be saved.
0:31:57 > 0:31:59The shadows are moving again.
0:31:59 > 0:32:01Those people
0:32:01 > 0:32:02are depending on you.
0:32:02 > 0:32:06Only you can save them.
0:32:06 > 0:32:07Only you.
0:32:15 > 0:32:17You travel with him, don't you?
0:32:17 > 0:32:20The Doctor, you travel with him.
0:32:20 > 0:32:22What of it?
0:32:22 > 0:32:24Proper Dave, could you move over a bit?
0:32:24 > 0:32:27- Why?- Just over there by the water cooler. Thanks.
0:32:30 > 0:32:31You know him, don't you?
0:32:31 > 0:32:35Oh, God, do I know that man.
0:32:35 > 0:32:37We go way back, that man and me.
0:32:37 > 0:32:39Just not this far back.
0:32:39 > 0:32:41I'm sorry, what?
0:32:41 > 0:32:43He hasn't met me yet.
0:32:45 > 0:32:49I sent him a message but it went wrong, it arrived too early.
0:32:49 > 0:32:52This is the Doctor in the days before he knew me.
0:32:54 > 0:32:56And he looks at me,
0:32:56 > 0:33:01and he looks right through me. And it shouldn't kill me, but it does.
0:33:01 > 0:33:03What are you talking about?
0:33:03 > 0:33:04Are you just talking rubbish?
0:33:04 > 0:33:06Do you know him or don't you?
0:33:06 > 0:33:09- Donna, quiet, I'm working!- Sorry!
0:33:09 > 0:33:12Donna? You're Donna? Donna Noble?
0:33:12 > 0:33:14Yeah, why?
0:33:16 > 0:33:18I do know the Doctor.
0:33:18 > 0:33:20But in the future.
0:33:20 > 0:33:22His personal future.
0:33:22 > 0:33:25So why don't you know me?
0:33:25 > 0:33:26Where am I in the future?
0:33:29 > 0:33:31OK!
0:33:31 > 0:33:33We've got a live one.
0:33:33 > 0:33:37That's not darkness down those tunnels, this is not a shadow.
0:33:37 > 0:33:39It's a swarm.
0:33:39 > 0:33:41A man-eating swarm.
0:33:44 > 0:33:48The piranhas of the air, the Vashta Nerada.
0:33:48 > 0:33:51Literally "the shadows that melt the flesh".
0:33:51 > 0:33:55Most planets have them, but usually in small clusters.
0:33:55 > 0:33:58I've never seen an infestation on this scale, or this aggressive.
0:33:58 > 0:34:00What d'you mean, most planets?
0:34:00 > 0:34:03- Not Earth?- Mmmm, Earth, and a billion other worlds.
0:34:03 > 0:34:05Where there's meat, there's Vashta Nerada.
0:34:05 > 0:34:08You can see them sometimes, if you look.
0:34:08 > 0:34:11The dust in sunbeams.
0:34:11 > 0:34:14If they were on Earth, we'd know.
0:34:14 > 0:34:16Nah, normally they live on road kill.
0:34:16 > 0:34:20But sometimes people go missing.
0:34:20 > 0:34:22Not everyone comes back out of the dark.
0:34:22 > 0:34:26- Every shadow?- No.
0:34:26 > 0:34:27But any shadow.
0:34:27 > 0:34:29So what do we do?
0:34:29 > 0:34:33Daleks - aim for the eyestalk. Sontarans - back of the neck.
0:34:33 > 0:34:35Vashta Nerada...
0:34:36 > 0:34:38Run! Just run.
0:34:38 > 0:34:41- Run where? - This is an index point. There must be an exit teleport.
0:34:41 > 0:34:44Don't look at me, I haven't memorised the schematics!
0:34:44 > 0:34:46Doctor, the little shop!
0:34:46 > 0:34:51They always make you go through the little shop on the way out so they can sell you stuff.
0:34:51 > 0:34:54- You're right! That's why I like the little shop! - OK, let's move it.
0:34:54 > 0:34:59- Actually, Proper Dave, could you stay where you are for a moment? - Why?
0:34:59 > 0:35:01I'm sorry.
0:35:01 > 0:35:05I am so, so sorry.
0:35:05 > 0:35:07But you've got two shadows.
0:35:14 > 0:35:20It's how they hunt, they latch on to a food source and keep it fresh.
0:35:20 > 0:35:22- What do I do? - You stay absolutely still.
0:35:22 > 0:35:25Like there's a wasp in the room, a million wasps.
0:35:25 > 0:35:26We're not leaving you, Dave.
0:35:26 > 0:35:29Of course not. Where's your helmet? Don't point, tell me.
0:35:29 > 0:35:32On the floor, by my bag.
0:35:32 > 0:35:33Don't cross his shadow!
0:35:41 > 0:35:43Thanks. Now, the rest of you,
0:35:43 > 0:35:46helmets on and sealed up. We'll need everything we've got.
0:35:46 > 0:35:49- Doctor, we haven't got any helmets. - We're safe anyway.
0:35:49 > 0:35:52- How are we safe?- We're not, that was a clever lie to shut you up.
0:35:52 > 0:35:54Professor, anything I can do with the suit?
0:35:54 > 0:35:58What good are suits? Miss Evangelista was wearing one, there was nothing left.
0:35:58 > 0:36:00We can increase the mesh-density, dial it up 400%.
0:36:00 > 0:36:02- Make it a tougher meal.- OK.
0:36:04 > 0:36:07- 800%! Pass it on.- Gotcha!
0:36:07 > 0:36:09- What's that?- It's a screwdriver.
0:36:09 > 0:36:11It's sonic.
0:36:11 > 0:36:13Yeah, I know. Snap!
0:36:20 > 0:36:23With me, come on!
0:36:26 > 0:36:28Are we shopping? Is it a good time to shop?
0:36:28 > 0:36:31No talking! It's a teleport, stand in the middle.
0:36:31 > 0:36:33Can't send the others, TARDIS won't recognise them.
0:36:33 > 0:36:36You don't have a suit, you're not safe!
0:36:36 > 0:36:38You don't have a suit, you're in just as much danger as me...
0:36:38 > 0:36:40Donna! Let me explain.
0:36:40 > 0:36:42Oh, that's how you do it!
0:36:42 > 0:36:44Doctor!
0:36:50 > 0:36:51SHE SCREAMS
0:36:56 > 0:36:57Where did it go?
0:36:57 > 0:36:59It's just gone.
0:36:59 > 0:37:01I looked round, one shadow. See.
0:37:01 > 0:37:03Does that mean we can leave?
0:37:03 > 0:37:06I don't know why we're still here. We can leave him, can't we?
0:37:06 > 0:37:09- I mean, no offence.- Shut up, Mr Lux.
0:37:09 > 0:37:12Did you feel anything? Like an energy transfer?
0:37:12 > 0:37:15No, no, but, look, it's gone.
0:37:15 > 0:37:16Stop there, stop moving.
0:37:16 > 0:37:19They're never just gone. And they never give up.
0:37:20 > 0:37:22SCREWDRIVER BLEEPS
0:37:22 > 0:37:25Well, this one's benign.
0:37:25 > 0:37:28Hey, who turned out the lights?
0:37:28 > 0:37:32- No-one, they're fine. - No, seriously, turn them back on! - They are on.
0:37:32 > 0:37:34I can't see a ruddy thing.
0:37:34 > 0:37:36Dave, turn round.
0:37:36 > 0:37:39What's going on? Why can't I see?
0:37:39 > 0:37:42Is the power gone, are we safe here?
0:37:42 > 0:37:45Dave, I want you stay still, absolutely still.
0:37:45 > 0:37:49Dave, Dave? Dave, can you hear me, are you all right? Talk to me, Dave.
0:37:51 > 0:37:53I'm fine, I'm OK, I'm...fine.
0:37:53 > 0:37:56I want you to stay still, absolutely still.
0:37:56 > 0:38:00I'm fine, I'm OK, I'm...fine.
0:38:01 > 0:38:03I can't...
0:38:03 > 0:38:05Why can't I? I...
0:38:05 > 0:38:08I can't...
0:38:08 > 0:38:09Why can't I? I...
0:38:10 > 0:38:12I can't...
0:38:12 > 0:38:14Why can't I?
0:38:14 > 0:38:16I...
0:38:16 > 0:38:18He's gone. He's ghosting.
0:38:18 > 0:38:21Then why is he still standing?
0:38:21 > 0:38:23Hey! Who turned out the lights?
0:38:24 > 0:38:26Hey! Who turned out the lights?
0:38:26 > 0:38:27Doctor, don't!
0:38:27 > 0:38:29Dave, can you hear me?
0:38:29 > 0:38:30Hey! Who turned out the lights?
0:38:35 > 0:38:36Who turned out the lights?
0:38:37 > 0:38:40- Hey! Who turned out the lights? - S'cuse me!
0:38:40 > 0:38:44Back from it, get back, right back!
0:38:48 > 0:38:50Doesn't move very fast does it?
0:38:50 > 0:38:52It's a swarm in a suit.
0:38:52 > 0:38:53But it's learning.
0:38:59 > 0:39:02- What do we do? Where do we go? - See that wall behind you?
0:39:02 > 0:39:03DUCK!
0:39:05 > 0:39:07Squareness gun!
0:39:07 > 0:39:10Everybody out. Go, go, go!
0:39:10 > 0:39:12Move it, move, move!
0:39:12 > 0:39:14Move it, move, move!
0:39:14 > 0:39:17- You said not every shadow. - But any shadow!
0:39:20 > 0:39:22Hey! Who turned out the lights?
0:39:22 > 0:39:23Run!
0:39:37 > 0:39:40Sweetie, dinner's ready.
0:39:40 > 0:39:42Donna Noble has been saved.
0:39:43 > 0:39:45Sweetie?
0:40:07 > 0:40:10Trying to boost the power.
0:40:10 > 0:40:13Light doesn't stop them, but it slows them down.
0:40:13 > 0:40:16So what's the plan? Do we have a plan?
0:40:16 > 0:40:17Your screwdriver...
0:40:20 > 0:40:22- Looks exactly like mine.- Yeah.
0:40:22 > 0:40:24You gave it to me.
0:40:24 > 0:40:27- I don't give my screwdriver to anyone.- I'm not anyone.
0:40:27 > 0:40:29Who are you?
0:40:29 > 0:40:31What's the plan?
0:40:31 > 0:40:34I teleported Donna back to the TARDIS.
0:40:34 > 0:40:38- If we don't get back in five hours, emergency program one activates. - Take her home.
0:40:38 > 0:40:40- We need to get a shift on. - She's not there.
0:40:40 > 0:40:45I should've received a signal, the console signals me if there's a teleport breach.
0:40:45 > 0:40:48Maybe the co-ordinates slipped. The equipment here's ancient.
0:40:48 > 0:40:50Donna Noble.
0:40:50 > 0:40:54There's a Donna Noble in this library, do you have the software to locate her?
0:40:54 > 0:40:56Donna Noble has left the Library.
0:40:56 > 0:40:59Donna Noble has been saved.
0:40:59 > 0:41:01Donna!
0:41:01 > 0:41:04Donna Noble has left the Library.
0:41:04 > 0:41:06- Donna Noble has been saved. - How can it be Donna?
0:41:06 > 0:41:08How's that possible?
0:41:08 > 0:41:11Donna Noble has left the Library.
0:41:11 > 0:41:15- Donna Noble has been saved. - Oh, Donna!
0:41:15 > 0:41:19- Hey! Who turned out the lights? - Doctor!

0:42:27 > 0:42:30I'd trust that man to the end of the universe. Actually, we've been.
0:42:30 > 0:42:33- Who are you? - And then you forgot.
0:42:33 > 0:42:36You just killed someone I like and it's not a safe place to stand.
0:42:37 > 0:42:38SHE SCREAMS
0:42:38 > 0:42:40This planet's going to crack like an egg.
0:42:40 > 0:42:42Daddy, no, Daddy!
0:42:42 > 0:42:45- I hate you sometimes!- I know!
0:42:47 > 0:42:51- Don't play games with me.- We need to stop this, we've got to save CAL.
