- We've lost it. - Must have ducked under the radar.
- I want it found. - We've done pretty well.
We've destroyed three and two have been shot down.
One unlocated UFO is one UFO too many.
Find it.

- This your car, miss? - Yes.
- Not a very clever way to park. - I don't remember.
- Anyone with you? - No!
No.
Could I see your driver's licence please, miss?
(Message on radio)
Reed to control. Red sports,
registration B bravo, M Mike,
W whisky, 189.
Would you get out the car please, miss?
What? Why?
Get out of the car, please.
I don't understand. I was just driving home when you stopped.
- Hey! - (Tyres screech)
(Siren blares)
(Horn honks)
(Tyres screech)
That was a stupid thing to try, miss. I think you better give me the keys.
- (Signal continues) - Give me the keys, please.
Don't give me a hard time, miss.
This is Commander Straker. Is Colonel Lake around?
Well, where is Colonel Foster?
No, no. Don't bother. Just spread it around I'm on my way in, will you?
I find it helps efficiency.
(UFO signal)
(Tyres screech)
- What's the problem? - Could give me a lift?
- What's the matter? - My car. Doesn't want to start.
Well, I...
I live down this road. If you could...
- All right. Jump in. - Thank you very much.
- I'm sorry to trouble you like this. - Forget it. It's no trouble.
- Oh, you're an American! - That's right.
- Boston. - Oh.
I find most Americans are very... mechanically minded.
- Oh? - I'm not, I'm afraid.
Take my car. It's probably just a lead, or wire,
- or something. - What is your line, Mr...
Clark. Daniel Clark. That's what I am. A bank clerk.
I pride myself on being a good judge.
I'd say you were some kind of executive.
- Yes. You could say that. - Oil?
Motion pictures.
Oh, films. That must be a very exciting life.
Anywhere along here will be just fine.
I live over there. Just beyond the wood.
Well, there we are, Mr Clark.
- Er, thank you very much. - Don't mention it. No trouble.
I...
- appreciate... - What's the matter?
(UFO signal)
(Straker) What's wrong?
(Beeping)
Commander Straker's car, sir.
- Where? - Three kilometres from junction 14.
(Groans)
How does it feel?
Like it's been shaken by an angry orang-utan.
I'm afraid you will live, Commander.
Thank you very much, Doctor.
Ah, Paul. What have we got?
Daniel Frederick Clark. Age 44, works in a bank,
- married with two children. - Nothing else?
No criminal record. Not even a traffic indictment.
A solid, law-abiding citizen. A Mr Average.
We'll find out more when we pick him up.
Mr Average threw me across the car like a rubber doll.
Yes. There are certain psychiatric conditions
that can impart tremendous physical strength for brief periods.
Tensions, stresses of one kind or another, build up and...
(Laughs)... and explode.
- Maybe you could take some time off. - Morning, sir.
No, I'm fine.
How are the new Interceptor pilots shaping up on Moonbase?
- How soon should they be ready? - In a month.
- A month? Nearer six weeks. - Thank you, Lieutenant.
Colonel Foster, I want you to read that.
What is it?
An ultimatum.
"Notice is given that unless the terms..."
The Fairfield tracker station and then Skydiver 3 will be destroyed.
Then SHADO Control and Commander Straker?
Unless SHADO ceases all operation.
Surrender? Where'd you get it?
Daniel F Clark must have slipped it into my coat.
These conditions - "Moonbase to be evacuated, all Skydivers to surface."
If Clark did write this, he knows a hell of a lot about our organisation.
I want a security check on all SHADO installations.
Get me a link to all Skydiver captains.
- Yes, sir. - Put Moonbase on yellow alert.
While we're about it, we'll have a security drill here. In 30 minutes.
- You're taking this seriously? - I knew a police captain.
He got 100 crank letters a week. The one he ignored killed him.
- Get on to the Fairfield commander. - Yes, sir.
(Alarm sounds)
- What is it? - 'Perimeter fence, sir.'
Get someone out there.
(Man) Get two men out to the fence.
(Engine starts)
(Man) You, come with me. Bring that Jeep over here!
- (Alarm winds down) - Over there!
Stay where you are!
On the ground! Move!
- Right. On your feet. Up. - Come on.
- Hands over your head. - Get to the Jeep!
Move!
We've got him, sir. We're coming in now.
(Communication on radio)
Has he been cleared by security control?
Yes, sir. We gave him the works. X-ray. Everything. He's clear.
Right!
Wait outside.
What's your name?
Clark. Daniel Clark.
But I seem to be... a little confused.
Well, Mr Clark, you do realise you've entered a restricted area?
- No. - You didn't see the notices?
Notices? No!
Do you own a typewriter?
No. No, I don't.
I see.
Guard!
Lock him up somewhere. And get me a security line to Control.
- I really can't remember... - Just keep walking.
(UFO signal)
Move!
'Well, Mr Clark, you do realise you've entered a restricted area? '
- 'No.' - 'Do you own a typewriter? '
- 'No. No, I don't.' - 'I see. Guard! '
(Door opens)
'Lock him up somewhere. And get me a security line to Control.'
64 seconds later an explosive detonation, force 17.
Well, Captain, you're the expert.
I have to admit, I'm baffled.
This man is stripped, checked electronically,
cleared on all counts.
These results show - radiation check negative,
X-ray negative, bio-sensors negative.
A force 17 detonation would take four pounds of our latest explosive.
Or two pounds of nitroglycerine.
The explosion centred on the main electrical switch panel.
Yes. A 10,000-volt input. If he'd tried anything there,
he would just have blown the fuses or electrocuted himself.
At worst he may have started a fire.
Was there anything already on the base that he might have used?
No. No explosives of any kind. No nuclear material, nothing.
You know, you can make a bomb out of a bag of flour,
but not a detonation of this magnitude.
Captain, I want you to go to our naval installation.
I'm putting you in command of security
on Skydiver 3, the next target.
We need to take this section down further.
We won't be able to get near it till the end of the week.
End of the week?!
- We're behind schedule. - What?
I said, we're behind schedule as it is.
- What you have to do is... - (UFO signal)
...move some of the men. - You OK, Mr Mason?
Get out the way! Get out the way!
(Car horns honk)
I'll need the file on the cost estimates and a copy of that report.
It should be ready this afternoon. I made the reservations in Geneva.
- Good. Tickets? - In your briefcase, with the cash.
Thank you. That takes care of everything.
Just finish that report and get me those couple of calls.
Yes, sir.
(UFO signal)
And cancel all appointments for me on Friday.
I'll speak to the accountant first.
- Miss Simmonds? - Excuse me, sir. I must go.
- Are you all right? - I have to leave!
I don't understand. Is anything wrong?
- I must go. At once. - You don't feel well. Sit down.
No!
'Skydiver 3 was due to sail tomorrow.
'But changes its departure time to 2100 hours tonight.'
I'll be aboard.
'I told the captain to remain at sea until further orders.'
Good idea. Once we're mid-ocean, we should be safe.
'Let's hope so.'
(Doorbell)
Hey! What do you think you're doing?
(Groans)
(Moans)
- (Crackling) - (Screams)
- Commander Straker for you, sir. - Right.
'I want to check on your departure time, Captain.'
We'll make 2100 hours all right, sir.
'Have you searched the ship? '
Yes, sir. We've been all over her with electro-scanners.
That's fine. Good luck, Captain.
Well, there's nothing more we can do, except wait.
Isn't there, Paul? I seem to recall an unlocated UFO.
- I want it found. - Yes, sir.
- Security. - (Man) 'Captain Lauritzen's here.'
Good. We're expecting him.
Captain Lauritzen's here.
Good evening, Captain.
May I have your pass, please, sir?
- Thank you, sir. - Can I check your case please, sir?
Travelling light, sir?
Fingerprints please, Captain.
Thank you, sir.
Well, everything seems to be in order, Captain.
Go right ahead, sir. They're expecting you on board.
Get me Skydiver.
(Beeping)
- Skydiver. - Security, sir. We have an intruder.
- Is he armed? - 'No, sir.'
Right. Sound a general alert.
- This is an alert. - (Alarm)
Get me Commander Straker.
(Man) 'Voiceprint identification.
'Request voiceprint identification.
'You have five seconds.
'Voiceprint negative.'
- Where is he now? - 'In the voiceprint trap.'
- 'Get that submarine out to sea.' - We'll be right underway.
- Clear fore and aft. - Sever ship to short umbilicals.
Yes, sir. Sever ship to short umbilicals.
- Clear the deck and secure hatch. - Clear the deck.
Yes, sir.
Hatch secure, sir.
Let's go.
- Slow ahead. - Slow ahead.
Check it.
- He's gone! - He must be aboard.
What?
- How? - It seems he forced the doors.
- Get Skydiver 3. - Yes, sir.
How could one unarmed man cut through five centimetres
- of steel plate? - Captain on the line, sir.
Captain, it's highly probable that you have a saboteur aboard.
'Lf there is, sir, he can only be up top.
- 'We can handle it.' - Yes, I'm sure you can, Captain.
- Keep me informed. - 'Yes, sir.'
- Break out the small arms. - Yes, sir.
He's on the conning tower, sir.
Out of the question.
'We could open the hatch and rush him.'
I said no, Captain. Have you reached the safe dive area?
- Yes, sir. Just about. - 'Then take her down.'
- Sir? - 'I said submerge.'
Commander, there's a man up there. One unarmed man.
'Captain, I gave you a direct order.'
Take her down.
Dive! Dive! Dive!
Dive one and two.
- What a mess. - What did that to his hands?
I don't know.
Let's take a look around.
Paul.
Clem Mason. 35. Construction manager.
Suddenly walked off the site yesterday afternoon. No record.
Another Mr Average.
It doesn't add up.
He kills Lauritzen, tries to get through the security net,
is discovered, gets caught in the voiceprint trap,
and then gets out through tungsten steel doors.
He was unarmed and had nothing on his person.
Right! He gets aboard Skydiver 3,
a ship that's been checked with the most sophisticated devices we have,
and yet, minutes later, it's blown out of the water.
You said he was a Mr Average.
But no normal man could have clawed his way out of those doors.
So he possessed or was possessed by some superhuman force.
Hmm.
In place of superhuman...
try alien.
And you are next on the list, Commander.
More important, so is this control centre.
Feed every scrap of information into the computer,
no matter how insignificant.
Bend the program if necessary.
- Morning. - Hello.
Hey, take a look.
Yeah, that could be something. I'll check the details.
- (Knock at door) - (Man) Come in.
- Morning, sir. - Miss Simmonds. I didn't expect you.
Didn't expect me? I want to make sure you catch that plane.
We've been looking for you. I contacted your parents.
- Are you all right? - Fine. Why?
Miss Simmonds, leave all that. Yesterday afternoon, you...
- Yes, sir? - I think I ought to call someone.
A doctor or...
(UFO signal)
I wouldn't do that if I were you.
Yes, that's right. Immediate.
- We may have something. - Good.
Clark and Mason live in the same area.
The computer's produced a police report.
Two nights ago a patrolman was murdered.
The police surgeon states that almost inhuman strength
- was used to strangle him. - The time of death was 2200 hours.
The patrolman reported in at 21.54.
He was checking on a car by the roadside.
The car is registered to a Miss Linda Simmonds,
who lives less than a mile from Mason. We have her address.
That's the best lead we've got so far. Let's go to work.
(Beeping)
Got anything for a size A problem, deluxe version?
A stomach upset's easier to cure.
Yes, I'm sure it would be.
Doctor, you said something the other day that stuck in my mind.
You were talking about psychiatric conditions,
how tensions and stresses can build up in a person until finally...
- Subject explodes mentally. - And physically?
Yeah. I have a theory.
But I must warn you,
it's pretty wild.
Go ahead, Doctor. Try me.
A human body - muscles, brain -
operates in a series of minute electrical charges,
flowing around a complex of low voltage electrical circuits -
the nervous system.
Sometimes the electrical balance is disturbed.
Mental disorder?
Imagine the situation where, for some reason,
the balance swings violently off centre.
The body becomes supercharged.
Like a thunder cloud before a storm.
If such a charged being could exist,
it may be able to draw on all the primitive forces of the universe,
attract them to itself.
Space, time, light...
electrical potential, energy -
they're all related!
- The result... - A human bomb.
A psychobomb.
Foster to Control. I've checked Miss Simmonds' apartment. She's not there.
(Horn honks)
Can I see your pass?
- Thank you. - Thank you.
- What happened? - A man's been killed.
- Who did it? - We don't know yet
but whoever it was beat his head to a pulp.
- Miss Simmonds. - Yes?
My name's Paul Foster.
That looks very impressive.
A couple of nights ago you were driving along route 107.
- Yes. - In this car.
Yes.
- Oh, the police. - What about the police?
A patrolman stopped me. I still don't know why.
- I'd like to talk to you about that. - OK.
Why not?
Let's take a walk.
Paul, it looks like Miss Simmonds is it.
She must be considered highly dangerous.
Paul?
'Come in, Paul.
'Come in, Colonel Foster.'
Well, Mr Foster, you wanted to talk to me.
Er, yes. Er...
How about some lunch?
The UFO's been in the earth's atmosphere nearly 48 hours.
It must move soon before it starts to disintegrate.
Let's concentrate the search area... here.
Yes, sir.
- Mobiles are moving in now, sir. - Good. What about Foster?
Still can't contact him.
Been in the office at all today?
- How d'you know I work in an office? - We have our methods.
My boss is flying out to Geneva. He's a big man.
- You don't like him? - Yes. I think he's sweet.
I always call him sir.
Look at the fish!
There's a big one.
It's funny. I feel I've known you a long time.
Four hours.
(UFO signal)
- Well? - Search still negative, sir.
- Keep them at it. - Yes, sir.
To all sections. Repeat, to all sections,
SHADO Mobiles 1 and 2 are proceeding into new search area.
- Paul? - Hmm?
Why did you come to see me?
I don't know. Maybe it was your personal magnetism.
Seriously, why all the questions?
- Routine. - Just routine?
There's nothing to worry about.
(UFO signal)
But you do believe me?
Don't you, Paul?
(Echoes) 'Don't you, Paul? Don't you, Paul? '
He's what?
Foster is bringing Linda Simmonds to the studio!
Commander, did you hear what I said?
- I heard. - She is programmed to kill you.
Her target is also this control.
I'd rather fight that situation on my own terms.
When she arrives, take her to room 22.
- But... - That's all, Colonel.
Still nothing, sir.
This is Commander Straker to all mobiles and search aircraft,
it is imperative, repeat imperative,
that the UFO be located as soon as possible.
Commander.
I can't explain it. I believe she's innocent, but to bring her here.
Forget it, Paul. In the end it was my decision.
- Where is she now? - In 22.
- Who's with her? - Colonel Lake.
Now don't give me "I don't know." I want answers!
- Why did you kill your boss? - I didn't!
- And the patrolman. Why? - I don't understand...
You put your hands round his throat and choked him.
- Stop it! - You pressed and pressed!
Stop it, please! (Sobs)
Guard.
Can't believe it.
That she could cave in a man's skull with her bare hands? A psychobomb.
The ability to call on the potential of the entire universe.
- What triggers it off? - UFO lifting off.
(Sobs)
(UFO signal)
Stay back.
That's far enough.
I said that's far enough!
One step more and I'll fire.
Area Four green. Ground radar have it on positive track.
(Man) 'Sky 4 to Control. Have UFO on radar.'
- How far? - 'In range in three minutes.'
Miss Simmonds!
You gave us an ultimatum.
Surrender. Surrender SHADO.
You know that we can never do that.
You have no alternative.
High voltage. That's the trigger!
The UFO that controls you has been destroyed!
Miss Simmonds!
If you touch those cables...
Surrender!
(Screams)
- Emergency circuits! - Linda!
(Man) 'UFO destroyed. Returning to base.'
How did you know Sky 4 had got that UFO?
I didn't.
