Doctor Who (1963) s15e07 Episode Script

(DOCTOR WHO THEME) MARIUS: Well, here we go.
(VISIPHONE BEEPS) Your time is up.
Surrender the Doctor! Pleasant journey, Doctor.
(PANTING) Well, what do you think? I don't know what to think.
I've never been inside anybody's head before.
Yeah.
-It's very interesting.
-Thank you.
Hey, why are we wet? Because we're too small to break the surface tension.
(BEEPING) -What was that? -Ah, just a passing thought.
Electrochemical reaction in the synapses.
Leg wants to move.
I don't think he can hold up much longer.
The virus is strengthening its grip.
(VISIPHONE BEEPS) Marius.
You have not replied to my ultimatum.
I shall destroy this centre.
No, wait! I agree to your terms.
I have no further use for the Doctor.
He's yours whenever you want him.
A wise decision.
Tell me, Professor, is the woman, Leela, with you? No, as you can see, there's simply myself and my two assistants.
She is somewhere in the Foundation, but I have no idea where.
No matter.
She will be destroyed.
Stay where you are.
We are on our way.
Leela.
They're coming now.
We must hold them up for -Can I borrow K9? -Yes, certainly, certainly.
K9, cooperate with Leela.
Master.
What we need is that corridor.
Corridor X3.
Yes, if we can just make some sort of barrier Recheck.
First we must eliminate the service shaft.
Of course! They can attack us from behind.
-You haven't got much time.
-Right.
K9, you destroy the shaft and meet me in the corridor.
Affirmative.
Suppose they fail? Have you ever used one of these? Thank you, sir.
Parsons, if by any chance I'm taken over by the virus, I hope you won't hesitate to use that on me.
Because I certainly will on you.
We must give the Doctor his 10 minutes.
I understand, sir.
(SIREN WAILING) -Doctor.
-Yes? I do not think you have any idea where we are going.
What do you mean, I've got no idea where we are going? We're travelling along my neural pathway, looking for a bridge, a crossover point between the left lobe and the right lobe.
Is that where the virus will be? It seems to control the conscious and unconscious.
-It's a good enough place to start.
-Suppose we meet it? What? No, no, no.
It came here through the optic nerve.
We are somewhere between the spinal cord and the cerebellum.
But keep your eyes open for tissue deterioration.
Like this? (BEEPS) Ah! -That's me you're kicking.
-Oh! Sorry.
Mission accomplished.
Service shaft destroyed, mistress.
Thank you, K9.
Now, what we need here is some sort of barrier.
(BEEPING) Acceptable? Perfect! Thank you, K9.
There is no need for gratitude.
I am an automaton.
Really? I am without emotional circuits.
Only memory and awareness.
Attention! Four hostiles approaching.
It's the reject.
Leela.
Leela, bring me the Doctor.
Come and get him.
Eight minutes to go.
Anything? PARSONS: It's all there, sir.
Leela's tissue profile, adaption, disease resistance.
Bit of a mongrel, isn't she? I imagine that's why her race survived.
There's no sign of any physical immunity.
There is a wide variation in blood characteristics, sir.
It'll take hours to check them all.
On the other hand, there could be a psychological factor.
-You mean, not physical at all? -Yes.
Something in her mind, her way of looking at things.
Aggression.
Determination, stamina.
The predator's instinct.
(ORGANS BEATING) Doesn't look like the most advanced computer system ever, does it? Ugh! What's that? That is why my brain is so much superior to yours.
-Doctor.
-What is it? -I can sense danger.
-Rubbish! If there was any danger about, I'd be the first to scent it.
I know this brain like the back of my hand.
Danger What do you know about brains, anyway? All right, all right.
Don't get excited.
I'll get excited if I want to, it's my brain.
Danger, I'll tell you something about brains.
-Do you want to know something? -Not much.
I'll tell you anyway.
Somebody once tried to build a machine as efficient as the brain.
Only trouble was, it would have had to have been bigger than London.
Do you remember London? And powered by the entire European grid.
And that was just a human brain.
Mine's much more complex.
Left and right sides, working in unison via the specialised neural ganglia, thus combining data storage and retrieval with logical interest and the intuitive leap.
-And here Are you listening to me? -Yes, Doctor.
That is the reflex link.
Whereby I can tune myself into the Time Lord intelligentsia.
Thousand super-brains in one.
-Why don't you do it now? -What? Oh, well I lost that particular faculty when they kicked me Oh, look! -Kicked you out? -Oh, look! Connection seven.
-Hello.
-Hello.
Don't be funny.
Doctor, you're wasting time.
Keep moving.
No, no, no.
Come on over here.
This is recent damage.
-It's a virus? -What else? We must be getting close to it now.
-What's that? -What? (LEELA SCREAMS) Doctor! Doctor, help me! I can't.
It's my body defence mechanism.
They're my own phagocytes.
Use your knife.
(SCREAMING) -Oh.
-What did you do? I think I told them my liver was disintegrating, I think.
-That's very clever.
-That's very clever.
What was that? It only proves they are in there in some sensitive area.
(GUNS FIRING) They're coming closer, sir.
Seven and a half minutes.
Not much chance.
K9: Contact has been made.
Master.
(BEEPING) Oh! After you.
-Are you afraid? -Not necessarily, no.
From now on, we're on the trail of the virus, -and that's the path it took.
-Where to? Well, if I knew that, I wouldn't have brought you along.
From now on, this is where your tracking skills come in.
Kill.
Kill the reject.
Affirmative.
Kill the reject.
Reject liquidated.
K9 into self regeneration.
Non functional Good.
Now for the Doctor.
-Ah! -What is it? Something banged my head, a real bump, but -What? -There's nothing there.
-That was your outside head.
-Oh.
-That's all right, then.
-No, it isn't all right.
You and I have only got a limited life in here.
Your outside self and your inside self are made of the same tissue.
Your outside self is hurt, then you feel a shock.
Your outside self is killed Yes.
We better make the most of the next six minutes, then.
-Yes.
-Where are we? This is the gap between one side of our mind and the other.
-But it's dark on the other side.
-Well, of course it's dark.
It's the gap between logic and imagination, passing one side from the other side.
-But it is there -What? There is something on the other side.
This is the mind-brain interface, Leela.
At least I think it is.
That's the mind and that's the brain.
Two things entirely different but part of the same thing.
-Oh, like the land and the sea? -That's right, that's right.
-It's very deep.
-Yes.
Sometimes, I don't quite understand it myself.
Five minutes to go.
Don't move, Professor.
-Release the Doctor.
-No, I can't.
Contact has been made.
Release him.
-We must make contact with the Nucleus.
-No, no, wait.
-The Nucleus is in danger.
-What? Micro-cloned copies have been injected into his brain.
And are even now trying to hunt down and destroy the Nucleus.
-If they succeed -They must not succeed! We can't stop them.
There is no time.
I say we must! Mistress.
Why did you attack me? I had to.
I was temporarily overpowered.
And my motivational circuits were in confusion.
I have now regenerated and await your further orders.
Where are the others? Have they got the Doctor? Affirmative.
(BEEPING) They've got Professor Marius.
He's been taken over by the virus.
-And they've killed Dr Parsons.
-What are they doing now? Well, they're cloning Lowe and they're going to inject him into the Doctor's brain.
Then we better stop them.
Negative.
We must wait.
Maintain surveillance.
Why? We cannot interfere while there is still a possibility that the Doctor will succeed in destroying the Nucleus.
-Bracing, isn't it? -Very.
The interface.
The mind unsullied by a single thought.
Where are we going, Doctor? Into the land of dreams and fantasy, Leela.
Hurry.
Hurry.
NUCLEUS: Hurry! Hurry! They are closing in.
Hurry, hurry, hurry! Is this your land of dreams and fantasies? Well, on the way to it.
The evil thing Very close.
And another.
Doctor, we're going to be trapped.
Who are you? I am the Nucleus.
You're trespassing, you know? Treading on my own conscience, affecting my metabolism Nucleus of what? The Nucleus of the Swarm.
Oh.
Oh, I see.
Why did you choose my brain? Because of your intelligence.
Well, I can understand that, but do you realise you have no right I have every right! It is the right of every creature across the Universe to survive, multiply and perpetuate its species.
How else does the predator exist? We are all predators, Doctor.
We kill, we devour, to live.
Survival is all.
You agree? Oh yes, I do, I do.
And on your argument, I have a perfect right to dispose of you.
Of course, the law is survival of the fittest.
Touche! Your time is running short.
How do you intend to dispose of me? You have no weapons.
And in minutes, you will cease to exist.
I am the virus of the Nucleus of the Swarm.
For millennia, we have hung dormant in space waiting for the right carriers to come along.
Carriers? What do you mean, carriers? I'm not a porter.
Consider the human species.
They send hordes of settlers across space to breed, multiply, conquer and dominate.
We have as much right to conquer you, as you have to strike out across the stars.
But you intend to dominate both worlds, the micro and the macrocosm.
We have waited, waited in the cold wastes of space.
Waited for mankind to come.
And now we have not only space, but time itself within our grasp.
Time? Through you, Time Lord.
(GROANS) (SCREAMING) So, Doctor, how can you puny creatures compare yourselves to us, the Swarm? The new masters of time, space and the cosmos.
New masters? Not if I can help it.
But you cannot.
Your time is up.
You have fallen for my stratagem.
Already, you cease to exist.
Get out of my brain.
Get out of my brain! DOCTOR: A tear duct.
A tear duct.
A tear duct.
A tear duct.
A tear duct.
A tear duct Destroy them.
Destroy them now! No! We must find out what happened.
We must restore them to their full size and interrogate them.
