Doctor Who

'Private journal of Captain Jonathan Moran,

'21st November 2119.

'We have located a craft of unknown origin on the lake floor.

'Visual scans in situ revealed nothing,

'so we have brought the craft on board

'and myself and the crew will now investigate.'

How did they miss this in the initial survey?

WATER RUNS

Cass says it was buried,

and the currents of the water must have shifted the rubble around.

A conversation needs to be had about who owns this spaceship.

Can we stop calling it a spaceship?

We don't know what it is.

A case could be made that this is an asset,

and my company has bought the rights to all assets...

Whoa, whoa.

What's this?

Lunn, grab me a torch, will you?

It was found on MOD property, even if that property is underwater.

What you bought is the oil under the ground...

Lunn! Where's the torch?

- Can I go in? - What is the radiation count?

- Pretty much background level. - Anything more,

it would have shown up on the initial survey 20 years ago.

If it's not safe, how come you can go in?

"How long do you think it's been down here?"

Well, there's next to no corrosion.

I've not seen technology like this...

Please don't say "on Earth".

- .. on Earth before. - HE SIGHS

Maybe it's some kind of experimental craft that got left behind

when they abandoned the site.

Wait, you think the Army would just lose a prototype weapon?

You're new to the military, aren't you, son?

Cass says he might be right.

It might have been here since the 1980s, when the valley flooded.

Cass!

BEEPING

Come on! Move!

Come on, we need to go now!

ALARMS BLARE

'Fire in the main hangar.

'Safety protocols have been initiated.

'All crew must evacuate immediately.

'This safety message was brought to you by Vector Petroleum.'

We can't just leave him!

There was something in the spaceship, I saw it!

- O'Donnell, he's dead. Didn't you see? - The fire, are we safe out here?

It's fine, the CO2 will put the fire out.

It was you! You were messing about with the controls on that ship!

SHE SCREAMS

Moran. But...

.. we just saw you...

He's...

Oh, my God.

He's a...

ghost.

METALLIC THRUMMING

What's wrong?

You're not happy.

Why aren't you happy? Tell me.

Come on! We're on a roll!

Monsters, things blowing up.

Oh, hey, can we go back to that place

where the people with the long necks

have been celebrating New Year for two centuries?

I left my sunglasses there.

And most of my dignity.

Why have you brought us here?

Here being...?

Underwater.

Some sort of a base.

The technology's 22nd century.

Maybe military, maybe scientific.

Is there a crew?

Must be, somewhere, if there's oxygen.

I want another adventure.

Come on, you feel the same.

You're itching to save a planet, I know it.

Doctor, look at this.

Well. Looks like you got your wish.

- Food fight? - I think there was more to it than that.

Whatever it was, it happened pretty recently.

Seven or eight hours ago.

No bodies, though.

And they took provisions.

OK, so something or someone forced the crew to abandon the base.

Maybe they went for a swim

in the creepy flooded village outside...

Oh, yeah. You see, this is more like it.

Oh, come on.

Don't leave me hanging.

Look. Told you.

Crew.

Hello, sailors!

GHOSTLY WHISPERING

Right, I did not expect that. Hands up who expected that.

Wait, wait -- I don't think they're going to hurt us.

I think that they're just curious.

Are you sure?

Well, I mean, define "sure".

Look at you lovely chaps.

What's happened to you, then?

Come on.

- What are they? - I haven't a clue.

Isn't that exciting?

Where did they go?

- What is it, some kind of submarine? - No, it's alien.

That's weird. The Tardis hasn't translated it.

GHOSTLY WHISPERING

Hey, look, they're back.

Hello! Did you want to show us this?

It's very nice.

THEY WHISPER

Wait, are they saying something?

OK -- they now appear

to be arming themselves.

Yes, I spotted that, too.

Was it something she said? She does that.

She once had an argument with Gandhi...!

I'm starting to see why the crew did a runner.

SHE SHRIEKS

Run!

In here! Quick!

What are YOU?

Who the hell are you, and what are you doing here?

This is Clara,

and I'm the Doctor.

You're from UNIT.

Well, if that's what it says.

I'm Pritchard, this is Bennett.

O'Donnell!

Are you really the Doctor? I'm a huge fan!

I mean, um, you know...

Nice work.

Tim Lunn, I sign for Cass.

Tell me, what about those things out there, what are they?

- Why are they trying to kill us? - Well, they're...

- They're ghosts. - They're not ghosts.

Cass is saying...

Thank you, but I actually don't need your help.

I can speak sign.

Go ahead.

SOUNDLESS

No, no, actually, I... I can't.

It's been deleted... for semaphore.

Someone get me a selection of flags.

One of the ghosts is our previous commanding officer.

The other, um... moley guy, we don't know what he is.

- He's from the planet Tivoli. - See?

I told you he was an alien! Didn't I say that?

Weird thing is, they're not violent. They're too cowardly.

They wouldn't say boo to a goose.

They're more likely to give the goose their car keys and bank details.

When did they first appear?

Oh, did you see that spaceship in the hangar?

Yeah, we found that on the lake bed and we'd just got it on board

and one of the engines started up and then Moran got...

Moran was killed.

Then they appeared

and pretty much straightaway started trying to kill us.

So we grabbed what we could and we were looking for somewhere to hide

and that's when we realised the ghosts couldn't come in here.

- What is this place? - It's a Faraday cage.

Completely impenetrable to radio waves

and, apparently, whatever those things are out there.

So, who's in charge now?

I need to know who to ignore.

That would be me.

Her.

Actually, that would be me. I represent Vector Petroleum.

- We've obtained the mining rights to the oil. - The oil?

- Where are we? - This used to be a military training site.

There was a dam overlooking it,

but the dam burst and the valley was submerged.

Then, 20 years ago, we discovered a massive oil reservoir underneath it.

'Good morning. Entering day mode.'

OK, it's morning. We can go outside now.

Thank God for that.

At last, we can get out of here.

Morning?

Yeah, we're too far below the surface for daylight,

so we have to demarcate artificial days and nights.

I'd like to have a further look at that spaceship,

but what about those things that aren't ghosts?

It's all right. They only come out at night.

Weird how that is not comforting.

- If whatever they are... - They're ghosts! - They're not ghosts!

.. have been trying to kill you, why haven't you abandoned the base?

That was my call. We have 1 trillion worth

of mining equipment here.

We're not just going to abandon it...

What? If it all goes pear-shaped,

it's not THEM that lose a bonus.

It's OK. I understand.

You're an idiot.

Come to mention it, why is there a Faraday cage on the base?

It's the mining equipment. It runs on nuclear fission.

The Faraday cage has been lined with lead

to act as a shelter in the event of a radiation leak.
