Somebody help me, please.
I'm suffocating.
Quickly.
Somebody help me, please.
I'm suffocating.
Help me, please.
Yeah, but what about me, brother?
I'm afraid I've got something more serious to look into first, miss.
If this young man's telling the truth, a colleague of mine's been murdered.
Doctor, there's a man here who wants to talk to you.
Oh, who is he?
There you are, sir.
Detective Inspector Crossland.
Scotland Yard.
I've told him everything.
Have you ever seen that man?
That's the man we found in the chameleon tour's hangar.
The doctor's body.
Where is it?
He escaped.
His intelligence is far above normal beings.
Above yours, perhaps.
I must leave.
The flight to Zurich is ready to take off.
You will remain here.
For what purpose?
To atone for your incompetence.
The doctor must die, and you must do it.
All right, then, Doctor, we'll go and see the commandant.
I want him to hear your story.
Well, he wasn't very impressed with it the last time.
This time, he's going to believe you.
Well, if you think so.
Jamie, stay here and keep an eye on the kiosk.
We shall be long.
And don't you worry about your brother, miss.
We'll find him for you.
That's not a good that inspector's going to be.
Ah, but he believes us.
Oh, yeah, but that doesn't mean it's a he's going to do anything.
I think I'll go and have a look around that chameleon hangar.
Ah, not by yourself.
Well, I suppose it would be better if I had a man with me.
Aye.
If only that doctor hadn't told me to watch this place.
Oh, do you always do everything you're told?
No.
But the doctor trusts me.
Yeah, that's your trouble, isn't it?
All right, stay here.
After all, they can only murder me.
Ta-da.
Oh, wait a minute.
I don't suppose anything will happen here, do you?
Well, since they've closed the kiosk, it's hardly likely.
And we won't be long away, will we?
Well, that depends on what we find.
Ah, come on, kid.
In any case, you'll need me to show you the way there.
Tower, Control, Mayor, clear to aid right.
All right, all right, I'll accept that you've found a body,
but I still want to know where you come from and why you have no passport.
Oh, but surely that's unimportant.
It is not unimportant to break the law.
Sir, I think we're going to have to let him tell us in his own way.
Oh, very well, make it brief.
Thank you.
I have just carried out a search of the Chameleon Tours hangar.
In a packing case, I found the body of a man.
You never told me that, Doctor. Another dead man?
No.
He was in a stupefied state, a sort of coma.
Who's this one?
I don't know his name, but I have a feeling he's one of your employees.
Oh, indeed.
In fact, I think he may be in here.
Taxi following Southern Taxiway for departure runway 27.
Sir, please show that picture to me.
Do you know what this is?
Looks like a fountain pen to me.
Things are not always what they seem.
Careful, it's dangerous.
Chameleon Tours are not quite what they seem, either.
Oh, and what's your theory?
Well, I'm afraid you won't believe it when you hear it.
First, Inspector Gascoigne was murdered with a ray gun.
A ray gun?
A weapon that has not yet been developed on this earth.
Oh, really?
Oh, you see, I knew you wouldn't believe it. What's the use?
No. Now be patient, sir. We are trying to understand you.
Very well.
Next, I believe Chameleon Tours to be merely a front, a cover.
For what?
For the mass kidnapping of young people.
And is all this supposed to be taking place in my airport?
Yes, at this very moment.
Oh, that's quite enough.
Can't you take that fellow into custody?
I'm very sorry, sir, but you know he hasn't broken any law except for this immigration business, and that's not my responsibility.
But Brian Briggs is your responsibility.
And who is he?
He's a young man who went on the Chameleon Tour and vanished.
Oh, now, come on, Doctor, wait a minute. We're not certain of that yet.
But he's nowhere to be found.
Well, no.
And neither are my two friends.
Which, to my mind, proves my point.
Chameleon Tours are a cover for the abducting of young people.
And just where do you think they're taking them?
Well, in view of the facts that I've already presented, the ray gun, this pen, and one or two other things,
I think we're dealing with people who are not from this planet.
That hardly answers my question.
What did you say?
Let me see. I knew you wouldn't believe me.
Oh, this is absolute harem nonsense!
Look, Doctor, I think you ought to produce some evidence to support all this.
Evidence? What about this pen?
A pen? You call that evidence?
I'll demonstrate it for you.
Excuse me.
Would you mind helping us?
I don't understand.
Could you hold this cup out in front of you?
Very well.
Oh, perhaps you've seen one of these before.
No, no, I...
It's turned to ice!
Would you call that arem nonsense?
Dear Mum and Dad, I've arrived safely in the Black Forest.
We'll write again soon. Love, Tim.
Dear Dad, I... Dear Mum...
Janey!
Janey! Look what I've found.
There must be 50 postcards here.
That should make that inspector do something.
Aye, you're right, and I know where to find him.
You're a brave wee lassie. No time to greet now.
Oh, get off! I've got something in me eye. Come on!
Where are we going?
Commandant's office.
Doctor, here are the remaining flight schedules for Chameleon 2 as you wanted.
What a nasty little device.
I think I'd better get that checked over, sir.
What the... Doctor! Doctor, don't hear...
I will not have my control room invaded!
Well, not even for these.
Why, what have you got there?
I think it's the further evidence you require, Inspector.
Yes, just as I thought.
Where did you get these?
In the office, in that hanger. Do you see what they mean?
All falling into a pattern.
This envelope is addressed to somewhere in Germany.
Yeah, Dane Chameleon Dreysen Freiburg.
That means Chameleon Tours.
Just what are you all talking about?
Well, you see, they give out these cards
and get the kids to write home to their parents
before they go.
Then the Chameleon Tours lot take the cards abroad
and they post them back to Britain.
So the parents think the children have arrived safely.
Doctor, what do you think does happen to them?
Now, now, now, this is all mere supposition.
Oh, to you maybe, but one of those kids happens to be my brother.
Your brother?
Aye, sir, this is the young lady whose brother's missing
and you see, she did get a card from him in Rome.
But why would anyone want to abduct these young people?
Well, if we knew that, we wouldn't be sitting here.
Inspector, can I have a word with you?
One minute for takeoff, two minutes left.
Go round.
You don't think this fellow's a little unbalanced, do you?
Oh, maybe a wee bit unorthodox, sir.
But after all, he's given us the only lead we've got so far.
If you could just see a way to give him a free hand.
A free hand?
Just to poke around a little bit, sir.
Don't you think it's safe to let the fellow roam around the airport?
He can rely on us to keep an eye on him, sir.
All right, but on your head, be it.
Well, I personally will investigate Chameleon Tours.
Then I'll report back to you here if I've found out anything.
But in the meantime, if you could just keep everything going as normal, you understand?
We don't want them to get wind of anything.
No, no, no, no.
Doctor, I'll give you the freedom of the airport,
for 12 hours, if heaven help me.
At the end of that time, I shall expect you back here with some real facts this time.
Thank you, Commandant.
Did they believe the doctor?
I don't know.
What do you mean?
I think he suspects me.
He turned one of our own weapons on me, forced me to leave.
You fool.
You should have stayed.
Now we do not know how much he has discovered.
Even if he has discovered the secret of our mission here, they will never believe him.
These earth minds cannot stretch that far.
Of course, the truth is beyond their intelligence, except for that doctor.
I know where he is. I could kill him.
You're going to, but not at the risk of your own safety.
We still need you in air traffic control.
Here, take this.
Attach it to him.
When we are ready, I shall activate the mechanism with this.
That should put pay to him once and for all.
Very well.
Don't delay.
I want him dead before Captain Blade returns.
Doctor, I've made out a pass for you and for your two friends.
Thank you very much.
Excuse me, sir. There's a chameleon flight coming in now.
Alpha Delta Sierra X-ray Lima calling Gatwick Airport Control.
Gatwick Control to Alpha Delta Sierra X-ray Lima.
I'll miss the takeoff two weeks left.
Gatwick Control to Alpha Delta Sierra X-ray Lima.
I will now give you your heading.
How many flights do they use a day?
Seven or eight.
How many planes do they use?
Four. I could get their registration numbers if you like.
Why do you ask?
Eight flights a day and only four planes. Is that normal?
Oh, yes. They have a very quick turnaround.
I mean, after all, they're only on short-haul flights.
You know, all the holiday centres, Spain, Rome, Athens...
Jean, where's the file on winter schedules?
Excuse me.
Which is the chameleon plane?
Oh, that one, sir.
Look, he's turning left at Dunsfold.
I shall hold him now over Epsom until I can give him landing clearance.
What's the range of your radar?
130 miles, sir. Why?
I was just wondering when this plane first appeared.
I've no idea, sir. We don't notice them until they start to call in.
Excuse me a moment.
Gatwick Control to Alpha Delta Sierra X-ray Lima.
Climb to 10,000 feet and hold in Epsom control zone to await landing clearance.
Alpha Delta Sierra X-ray Lima to Gatwick Airport.
X-ray Lima to Gatwick Airport. Climbing to 10,000 feet and to hold...
You were saying, sir?
How long do you hold them after take-off?
Once they've left Gatwick Control Zone, we finish with them.
Oh, I see.
That means they might be anywhere.
Aren't you rather wasting your 12 hours hanging around here, disturbing my people?
I don't think I've been wasting a minute, but I'll go if you insist.
Sam? Jamie?
Sorry.
Oh, it's all right. It's quite my fault.
Haven't I met you somewhere before?
I don't think so.
You must have a double.
Thank you.
Excuse me. Are you the manager?
I'm looking after bookings. Can I help you?
I'd rather like to speak to the man in charge.
Er...
I'm a police officer.
Is there some trouble?
I'd prefer to speak to the person in charge.
That's Captain Blade. He's just returned from one flight.
He's taking off for another. He's rather busy at the moment.
Perhaps I could go out to the plane.
I'll see about that. Just a moment, please.
The detective wants to see you.
Does he suspect anything?
I don't know.
All right. Send him over to the plane.
We'll deal with him.
Are you sure this is the right room, Doctor?
Jamie, have you ever known me to be mistaken?
Aye.
Hey, I'm not a doctor.
I'm a doctor.
Jamie, have you ever known me to be mistaken? Aye.
Hey, now watch out.
What?
That's the wall the gas nozzles came out of.
Well, there's nothing here now.
You're right.
That's clever. That's very clever.
Well, it makes life simpler for us.
Now, the man I froze came from here somewhere.
Aye, he would. A solid wall.
Well, somewhere in that solid wall there's a door.
And we still haven't found Ben and Polly.
What do you think's happened to them?
I don't know.
Perhaps if we find that door, we'll find them.
Come on, you take that and I'll take this.
Aye.
We must hurry.
Inspector Crosswell is keeping them busy at the moment.
But he'll be no match for them if he presses them too far.
You'll find that the whole plane conforms strictly to the international standards of air safety.
I don't think why anybody should have complained about us.
Did I say anyone had complained?
I'm not inquiring about safety.
My inquiries are about a missing boy, a passenger on one of your flights.
And it's also the business of a colleague of mine, Detective Inspector Gascoigne,
who was last seen in your hangar.
He's believed to have been murdered.
That is indeed a much more serious matter.
I'm afraid I'm going to have to ask you to hold up this flight a while while I ask you some questions.
If you wouldn't mind coming to the Commandant's office.
If you'll just excuse me for a moment, Inspector, I have some arrangements to make.
Excuse me, please.
I am sorry, lass.
Captain Blake!
I shouldn't move any further if I were you.
This gun proved remarkably effective in dealing with your colleague, Inspector Gascoigne.
You killed him.
Unfortunately, an error.
You Earthmen are more used to us alive.
Sit down there.
That's better.
This Earthman is a particularly fine specimen, don't you think?
Perhaps the Director himself.
Exactly.
Look, I don't know what you two are planning for me,
but I must warn you of the long arm of the British law.
I don't think it'll reach where you're going.
Chameleon flight 413 to control.
Request start up.
Jimmy!
Hey!
What's that, Doctor?
Someone who's not used to the Earth's atmosphere.
Any interesting...
Ah, a TV monitor set.
Let's see what we can see.
Hey, what's that?
Well, it looks like a hospital.
Jimmy, we're getting warmer,
which is a change from the last time I was here.
Come on.
Let's see if there's a first aid post in Gatwick Airport.
Shall we clear up the mess, Doctor?
No. Let's get along to the first aid post.
My back!
What?
Jimmy, my back!
Please take a seat.
You can listen as you are now.
Thank you.
Are you all right?
I'm fine.
You wanted to know what was the secret of Chameleon Tours?
Well, Inspector?
You'll find out soon.
