Doctor Who (1963–1989): Season 15, Episode 18 - Underworld: Part Two - full transcript

Crashing inside a newly formed planet, the Doctor and others find it inhabited by a slave labor mining society, where rocks are harvested for their radioactive energy and human life has little value. With a population controlled by deliberate cave-ins, poison gas, and periodic sacrifices to an Oracle, the miners, called Trogs, are also descendants from Minyos, and who desperately desire freedom.

Is there a way out?
- I don't know.

You could try the laser cannon.

Blast a tunnel
and blow our way out on ion drive?

Hmm.
- Tala.

It'll take up all our reserve fuel.

It's either that or we're stuck here
for the rest of eternity.

- We'll try it. Herrick?
- Sir.

Fire one.

Fire two.

Ninety meters, increasing.

Ninety-five meters, increasing.



Carry on, Herrick.

Skin's overheating.
The forward hull's buckling.

Carry on, Herrick.

We're melting our own hull.

Herrick, keep on!

It's no use.
The cannon's disintegrating!

One hundred meters. Penetration.
You have penetration.

Now, Tala. Full acceleration.

That's the P7E.
Captain, the fuel's going.

- What do you mean? That's a planet.
- That's where the signal is coming from.

- Where?
- Right in the middle.

The planet formed around it.

Captain, the fuel's gone.

That's it, then,
there's nothing else we can do.



Sit down, we're going to crash!

Full speed.

Mach 12, impact in 11 seconds.

Ten, nine, eight, seven, six, five...

- Hold tight.
... four, three...

- Hold tight?
... two, one, zero.

Stand by for impact.

You can relax now.

Relax, everyone. It's a soft planet
in the process of formation.

Only the core will be solid,

and with any luck,
this stuff should slow us down

so we don't hit it
with too much of a bang.

Two hundred and fifty kilometres
below planet surface.

- Speed, mach.3, decreasing.
- Orfe, the signal.

Tune in on the signal.

- That's it.
- We've got it!

Fascinating.
The Quest and nothing but the Quest.

Contact. R1C to P7E. R1C to P7E.

We must be right on top of it.

The sky is falling!

The sky is falling!

Help, damn you. Help us.

They won't, Father, they won't.
Don't say any more.

Then may the sky fall on them!

- May the sky fall on your families.
- No, Father.

The guards... They'll tell the guards.

May the sky fall on yours
as it has on mine.

- Please, Father, dig.
- My children, my children!

Skyfall on eight
and a Trog making trouble.

Many dead?
- Not enough.

There were two more bursts yesterday.
What we need is a good sacrifice.

Trogs always work harder
after a good sacrifice.

I'll take a patrol out, pick him up.

- Ready, sir?
- Well, Jackson?

Right, Orfe, open up.

Solid rock?
- Yes, solid rock.

- Igneous hematite, I should imagine.
- Igneous hematite?

That means we're at the core.

But I thought planets
had fire in the middle.

Well, old ones like Earth, yes.

But new ones have a molten slurry
down a solid core.

What we'll have to do is burrow our way
out of here, enter the core.

- Oh, is that all?
- But we've no power,

no energy source to recharge.

I don't know about that,
what about a shield gun?

Yes, a shield gun. Herrick, jump to it.

Sir.

We all know we're slaves to the guards
as the guards are slaves to the Seers.

- Say no more, Father.
- And the Seers to the Oracle.

We're all slaves.
All of us, of every class...

- slaves to the Oracle.
- They're coming, Father.

But we all know the answer, don't we?

We all know the answer
because it was prophesied.

- And the answer is to escape.
- It isn't, Father.

Escape through there,
through the sky to the stars!

Now!

- No.
- No, Idas. Idas, run!

- Run!
- Two of you, after him!

Heresy, treachery, incitement to escape.

There's nothing you can do
to me now, Rask.

You know the penalty, Idmon.

Stop, Trog, or I'll fire!

Suspect sighted on eight, moving nine.

Herrick!

Give it a blast.

Hold it. Like that, I think.

Fire!

We're through, Captain.

It looks like a cavern or a tunnel
or something.

Skyfall on nine.
Rask, we have Skyfall on nine.

Approaching nine.

Remain in position
till Skyfall investigated.

It's hyterrasan. Solid rock.
Hacked out by what, I wonder?

Get down, Herrick.

Minor fall, no structural collapse.

I'll check out the rest,
then you go ahead, Rask.

Checking now.

It's moving on.

- You think it was looking for us?
- It was looking for somebody.

This planet is inhabited, all right.

There is a tunnel
and a surveillance system,

so whatever life there is
is intelligent

and we must be on our guard.

- Oh, get on with it, Jackson.
- All in good time, Doctor.

Our objective is to locate the P7E

and remove the race bank cylinders
to a place of safety.

The Quest is the Quest.

The Quest is the Quest.

Shield gun.

- Silent routine.
- Sir.

- No, Doctor.
- The Quest is the Quest.

- Our Quest, Doctor, not yours.
- Of course.

- Welcome to the Underworld.
- Are we going to follow them?

- Of course.
- Good.

- Oh, what about K9?
- Oh, he'll be all right.

- He's building up his strength.
- Well, how? There's no power source.

- Mmm-hmm. Radiation.
- Radiation!

- That is lucky.
- Not at all.

Igneous rock core, new planet,
bound to be radiation.

Luck? Physics isn't luck,
physics is fact.

Are facts, is fact... Anyway, why do you
think these tunnels were dug out?

- I don't know.
- Exactly!

Energy. Can't survive on a new planet
with a soul full of hope

and fresh air, you know.

- Shall we go?
- Shh.

Shall we go?

Did I ever tell you about the time
I went to Aberdeen?

- Yes, the Granite City.
- That's right.

Do you know, the people there absorb
more radiation from the granite

than people who work every day
in nuclear power plants?

- Is that good for them?
- Well, of course it is.

It shows that organisms can adapt
to any kind of environment,

even one like this
with a high radiation concentra...

Look out!

- Looks like a wounded animal.
- Hmm.

- Why is he so frightened?
- I don't know.

- I'll ask him.
- Look. Get back.

You two, that pile of rubble.

After them!

Quick, in here.

Keep still.
- Hmm?

Keep still! Oh, for a weapon.

Not here. Must have doubled back,
damn Trogs.

Know these warrens
like the back of their hands.

Security, getting nowhere.
Not enough men, we're clearing out.

I want tunnel nine, main and ancillary
workings closed down once we're clear.

Stand by for fumigation.

Fumigation?
I don't like the sound of that.

They're going to smoke us out
like badgers. Come on.

Look, Doctor, blood.

- No. No!
- Surrender or die!

Don't, don't, don't. Get off him, Leela.
You're terrifying the poor fellow.

- Oh!
- He's wounded.

It's all right. We're friends,
she won't hurt you.

- She?
- Leela.

- She is like the guards.
- Really?

- Is it bad?
- I don't know.

Fetch me a tissue, Leela,
from the command deck.

Tissue? Tissue from the command deck.
Tissue, tissue...

- What's your name?
- Idas.

Idas?

- Hello, Idas.
- Hello.

Are you frightened?

These tunnels could stretch
for miles.

P7E must be at the end of one of them,
but which one?

- Split up, sir?
- Two pairs? No.

- Herrick?
- Sir.

- Reconnoitre.
- Yes, sir.

I'll just put a marker in, sir.

We three stay here.

Klimt here, possible suspect on nine.

Now, where in heat is...

Stop, Trog.

- Stop, Trog, or I'll fire!
- Hey, who are you?

- Stop, Trog!
- Don't Trog me, you...

Officer Klimt? Officer Klimt?

Clear tunnel nine. Clear tunnel nine.

Tunnel nine is being closed
for fumigation. Officer Klimt?

Officer Klimt?

Klimt? Come in, please.

Oh, Officer Klimt has retired. Suddenly.

Who is that? Who is that?

Well, this is Trog Herrick here,
who's that?

A Trog and he's armed!
Close down tunnel nine for fumigation.

Tunnel nine closing down.

Captain!
- Herrick!

- Tunnel nine closedown completed.
- Fumigate.

Fumigating now.

- Well, that shouldn't take much fixing.
- Are you a Seer?

What? Oh. Leela, thank you.

This is the one. Go back and unplug K9.

- Go back? But I've only just been there.
- Yep.

Linked up like that,
he's recharging the whole ship.

I'll need him soon,
the ship can look after itself.

Yes. Yes, Doctor.

Sting, did it? That's good.

Now, what was it
you wanted to know? Hmm?

- Are you a Seer?
- No. No, I'm just a traveller.

- Where? Where'd you come from?
- The sky.

- You lie.
- What?

There's nothing but chaos above the sky.

- The stars, then?
- Stars?

Yes, Idas.
This ship comes from the stars.

My father...
My father talked of the stars.

There's a prophecy amongst the slaves

that one day gods will come
and set us free.

Are you a god?

Well, no. But could you take me
to your father?

Why not?

There was a Skyfall.
All our family were buried.

My father said we should try and escape.

But the guards have taken him

and he's going to be sacrificed
to the Oracle.

- There's nothing anyone can do.
- We'll see about that. Come on, get up.

- I've unplugged K9.
- His name's Idas.

Hello, Idas.

Doctor. Doctor, look.

A trap. A trap to kill me.

Doctor? Doctor?
Doctor, where are you?

Doctor.

Get him to the command deck.
He'll be all right there.

- Where are you going?
- Out.

- Out there? You'll suffocate!
- Get him to the command deck.

Yes. Yes.

Whatever blows can be sucked.
