Synopsis: The space shuttle Churchill is assigned to observe the Halley's Comet under the command of Col. Tom Carlsen. They see a strange form attached to the comet and Carlsen goes with a team to investigate. They find three humanoid life forms in caskets and they bring them to the Churchill. However, Earth loses contact with the shuttle and the Space Research Center sends another spacecraft to search the Churchill. They find the crew dead and the shuttle burnt and one rescue pod missing. They bring the humanoids to Earth and soon Dr. Hans Fallada and his team discover that the Space Girl is a sort of vampire and drains the life force from people transforming them into zombies. When the authorities find that Col. Tom Carlsen has survived, they summon him to explain what happened in the Churchill. Carlsen tells an incredible story about the three aliens and he teams up with Col. Colin Caine trying to save mankind from the evil vampires from the space.

Greenwich Mean Time.

The H.M.S. ChurchiII,

outward bound.

On board:
a joint

British-American space team.

Their mission:
to intercept and study

the comet bearing Dr. HaIIey's name.

The ChurchiII is the first spacecraft

equipped with the Nerva engine.

It propeIs the ChurchiII

with constant acceIeration...

enough to create Earth-type gravity for

the first time on an extended fIight.

The ChurchiII is on course

for its rendezvous.

- Sir, this is odd.

- What?

I'm getting a smaII radar

cross section...

just ahead of the nucIeus

in the coma of the comet.

I've got it too. Check the Iength.

It's at the Iimit of my scan angIe.

- What's going on?

- You run an equipment check?

Every five minutes.

- Radar states 150 miIes.

- 150 miIes what?

- Length.

- 150 miIes Iong?

What's 150 miIes Iong?

It's a radar trace.

- Something in the coma of the comet.

- Show me.

- E.G.R. is confirmed.

- Looks good.

E.G.R. is optimaI.

Track three on three.


What's its height?

I've got a verticaI reading

of two miIes at Ieast.

Ambient temperature: six degrees.

Less than two percent traces

of manganese, titanium--

Try and raise base.

TeII them we have an artificiaI

object out here hidden--

- Are you sure you want to say ''hidden''?

- It's Iocated in the head of the comet.

Keep sending that

untiI they acknowIedge.

Use a secured downIink.

Sorry, Commander, everything's

been swamped by the coma winds.

We can't get anything back to base.

How Iong is the bIackout period?

AII the way.

What are you gonna do?

Go on in.

We're onIy gonna get one chance,


That thing won't be back

for another 76 years...

and we'II both be dead.

We have to take a Iook now.

- Shut down Nerva.

- Shutting down.


- SoIar paneIs retracted.

- Check. Give me a readout, Bob.

Executing E.V.A. maneuver.

Where do you suppose

this thing came from?

- Was it expIoring the comet?

- Come on, guys, Iet's do it.

The surface Iooks badIy pitted.

In that case,

it's been here a Iong time.

It's dereIict, whatever it is.

Stand by, ChurchiII.

We're going in.

Roger, CarIsen.

We copy. We have you going in.

ChurchiII, it Iooks Iike

some giant artery, organic.

I aImost have the feeIing

I've been here before.

Oh, boy.

This is incredibIe.

I hope you can appreciate

the scaIe of this on the video.

Roger. We're getting it.

It's aII on tape.

Oh, shit.

Whoa. Here they are.


it Iooks Iike we found the occupants

of the ship.

They Iook Iike giant bats.

- There must be hundreds of them.

- Thousands.

Dead, I hope.

Looks prehistoric.

It's compIeteIy desiccated.

- CrumbIes.

- Yes, it wouId.

AII the fIuid's been Iost

to space over the years.

We'II bag this one,

take it with us.

We're depIoying

the specimen bag.


What the heII is that?


the ship has just depIoyed a--

It Iooks Iike some sort

of big structure that's just unfoIding.

It's enormous.

God, what is it?

We must get out of here.

Nobody's going anywhere.

Stay where you are.

ChurchiII, this is CarIsen.

What's happening out there?

The thing stopped opening.

The onIy way to describe it is

it's Iike a giant umbreIIa.

Good God.

It's absoIuteIy enormous.

What's it doing now?

Nothing, sir.

It's stopped opening.

It's just sitting there.

- Can you teII what it's made of?

- Not metaI.

It's radar transparent.


If it starts up again,

Iet me know.

Any activity out there.

You understand?

Yes, sir.

That's where we're going.

There's something there.

Commander, this is ChurchiII.

We're Iosing our signaI.
