[Dr. Sarrazin] Welcome to today's demonstration.

I'm sure you'll see why I'm so excited about my latest find.

This first human test of the CAVE system

will shoot this institution to the front of the pack

in electro-cerebral research.

The patient's name is James Kendall.

He's suffering from severe paranoid schizophrenia.

He hears voices in his head of his dead father

telling him to kill his girlfriend.

We've tried the conventional therapies,

ECT, grades one and two,

all existing drugs, established and experimental.

None worked.

So, Mr. Kendall

has consented to be the first human subject

for the CAVE system.

And here is the genius behind the technology.

Gentlemen, ladies, my protege, Dr. Samuel Stein.

Thank you, Dr. Sarrazin.

Ladies and gentlemen,

I'd like you to meet the CAVE system.

Now, CAVE Stands for Computer-Aided Virtual Environment.

It's the first computer able to actually interface directly with the human brain,

which is exactly what we intend to demonstrate today.

I'd like to introduce the third member of our team,

a neurosurgeon by training, Dr. Rachel Carter.

Thank you, doctor.

Well, my position

on the team is to handle human interface.

These are the CAVE interface devices.

The silicon-to-neuron probe we'll insert directly

into the sensory centers of both the doctor's

and the patient's brains.

Don't worry. He didn't feel a thing.

The computer will then create

an artificial environment which it will send directly back

into the patient's brain

to treat the psychosis.

Since it will be tapping directly

into the sensory centers of the brain,

everything the computer sends will seem completely real.

The psychiatrist in the environment

with the patient, in this case Dr. Stein,

will be able to control

the CAVE and guide the patient.

I'm sure this may all seem very confusing to you.

But it will make sense in just a moment,

as the two men enter the virtual-reality world

of the CAVE environment.

Oh, God.

I'm afraid of fire.

Don't be, Mr. Kendall.

[man yelling] Get your butt over here!

Go away.

Get out of my head.

That's no way to talk to your old man. Now, is it?

What do you want from me?

I want you to get rid of that slut you've been running around with.

I want you to cut her heart out!

-No! -Don't talk back to me!

No!

I love her.

I'm marrying her.

Tell him, Dr. Stein.

You must fight your own demons, Mr. Kendall.

If you don't kill her,

she will ruin you, boy!

-No! -Ruin you!

No!

[alarm beeping]

I love her.

Jack him out, Dr. Sarrazin!

I love her. I love her. I love her.

Nobody's going to hurt you. We're here to help you.

You're okay.

You're all right.

[control voice] There is nothing wrong with your television.

Do not attempt to adjust the picture.

We are now controlling the transmission.

We control the horizontal and the vertical.

We can deluge you with a thousand channels

or expand one single image to crystal clarity

and beyond.

We can shape your vision

to anything our imagination can conceive.

For the next hour,

we will control all that you see and hear.

You are about to experience the awe and mystery

which reaches from the deepest inner mind

to The Outer Limits.

[control voice] Man has taught computers to perform

complex calculations,

to control a factory or to launch a spaceship.

But can we teach computers to enjoy the beauty of a rose,

the sound of a symphony,

or the love of another human being?

Sam, the sensory centers were overwhelmed with the input,

but he's going be fine.

I'm sorry. Next time, I'll cut the IO intensity in half.

Sam, it went damn well for a first time.

You know it did.

Sam, you should be very proud the technology works.

Would one of you please explain to me what I just saw.

Was I seeing what Jimmy was seeing?

Oh, yes. In that session we were

seeing output from his mind's eye.

Then in later sessions, the computer will add

its own imagery to the environment

so that we can, well, battle the psychosis.

But how does it know what to send?

The computer is a psychological expert system.

Everything written on human psychology is cataloged into the CAVE's ram.

And it uses artificial intelligence to interpret the data.

On that note, I would like to hear what the expert's diagnosis is.

All we have to do is ask.

It uses AI voice recognition capabilities.

CAVE, what is the diagnosis of the patient James Kendall?

[CAVE] The patient is suffering from coercive delusions,

prominent hallucinations and a decreased functionality.

My sensors found no trace of chemical causation.

Diagnosis, paranoid schizophrenia.

CAVE, what is the prognosis?

[CAVE] The only obstruction preventing the patient

from lapsing into catatonic psychosis

is his love for his mate.

With additional sessions,

there is a 78% chance I will be able to remove

all incarnations of his psychosis.

Does that mean it can cure him?

That's exactly what it means.

[CAVE] Further input on emotions fear and love

will be necessary.

-Can I see him? -Certainly. Come with me.

So...

She needs more input on fear and love.

Well, actually it's not gender specific.

You know, I programmed the female voice

because the female pitch is easier to understand.

Well, given how much time you spend with it,

she might as well be female.

I beg your pardon?

Sam, it's just that you're in here alone with this computer so much,

I sometimes wonder what you're doing with it. If you know what I mean.

I mean, you should try and spend a little more time with flesh and blood.

We're a lot more fun than Your AI interfaces and prologue code.

I spend a great deal of time with humans, Dr. Carter.

I mean away from work.

Sam, listen, a bunch of us are going away for the weekend to go skiing.

Why don't you come?

No, I don't think so.

Why not? It's going to be a lot of fun.

Call me crazy, but sliding down an icy hill

on two planks of wood just seems ti challenge the laws of gravity, don't you think?

Okay, then you can come along stay at the lodge,

sit in the hot pool and drink schnapps all day.

I don't think so.

Come on, Sam. What's wrong? Don't you like my company?

No, that's not it at all.

As a matter of fact...

I enjoy your company a great deal.

But I should check on the patient, really. Excuse me.

[sighing]

The CAVE has requested

additional information about the schematics of love and fear.

How do we give it that information?

Well, we're inputting several psychological studies on both emotions.

Unfortunately, not much has been written in scientific journals about love.

She's a beautiful woman, Sam, and probably

the only intellectual equal you'll ever meet besides me.

What's your point?

Let me tell you a story.

Oh, boy.

When I was about to ship out to the Korea during the war,

I was head-over-heels in love with a girl on my street, Sarah Long.

She was beautiful, she was smart, she was funny.

But I didn't have the gumption to tell her how I felt.

Is this in any way relevant to the CAVE system?

There I was with bombs falling all around me,

and all I could think of

was I can't die without first letting her know how I feel.

So I wrote a letter and spilled my guts.

You know what? It was too late.

She had met and married another man.

Get my drift?

Yes, well, I'm not going off to war.

What happened in your past, Sam,

to give you this fear of intimacy?

I don't have a fear of intimacy.

I'm shy.

Now I know that might not fit

into your lexicon of psychological lingo.

But I'm shy, that's all, okay?

I stand corrected.

Hello, Sam.

-Can I get under? -Sure.

It's a great night, isn't it?

What do you mean great? It's raining.

I love the rain.

I know, I came out here to be by myself,

but I can't get any work done in this.

Maybe that's God's way of telling you've done enough work.

I don't think there are enough hours in my entire life to finish

all the work I want to.

So what did you want to tell me?

-Tell you? -Dr. Sarrazin sent me out here,

said you wanted to tell me something.

Oh, he did, did he?

Don't keep me in suspense. What is it?

I wanted to tell you that...

Well, I think you're doing a great job.

You know, I'm glad to have you on my team.

Thank you. I'm glad I'm on your team too.

So, is that all you wanted to tell me?

Yeah, I guess, that's... that's all.

Okay, well, I'm going to take a walk in this wonderful rain. Do want to join me?

No, you know, I've really got to get this done.

All right, suit yourself. See ya.

I must be crazy.

Rachel!

Wait for me.

[horn honking]

Rachel!

Can somebody help me, please?

Stephanie, thank God you're on duty.

I figure there's no cranial fracture.

Chances are good, right?

I won't sugar-coat it, Sam.

I reviewed the scans and the counts.

And I think there's a good chance

Rachel may never come out of this coma.

Oh, God. No.

That can't be.

[Stephanie] I'm afraid so.

Has her family been notified?

She doesn't have any.

Her parents are dead.

She's got no brothers or sisters.

Stephanie, you're one of the best neurosurgeons we've got.

You must be privy to some new drugs or some new treatment.

I'm sorry, Sam. There are none.

[Dr. Sarrazin] Are you sure you're up for this today?

No one would complain if you stayed with Rachel.

If there's too much time between sessions,

the benefits to Mr. Kendall will be completely negated.

I mean, the goal is after all to cure the patient.

-Yeah, but another day-- -Doctor, please.

I'm sure Rachel would want us to go on with the project.

Are you ready, Mr. Kendall?

As ready as I can be. I guess.

[sighing] All right.

[father] All right, boy, I'll give you two choices,

kill her or kill yourself.

What's this?

Ever hear the saying "fight fire with fire," Mr. Kendall?

But this doesn't make any sense.

Fire only makes fire bigger.

I need water or something.

We're dealing in psychological symbolism here, Mr. Kendall.

You have to learn to use the tools you're given.

[screaming]

[Sam] You see, it is possible, Mr. Kendall.

You can win.

[father] No, you can't.

You can't beat me.

You never could.

So you might as well do what I ask.

Kill her!

-No. -Kill her!

I love her.

I love her.

I love her.

I love her.

I love her.

I love her.

I love her.

I love her.

I love her.

Sam, I could use a little help.

Yes.

I love her.

It's all right, Mr. Kendall.

I love her.

I love you.

Dr. Stein.

Mr. Kendall.

You feeling better?

Yeah. Yeah, I think I am.

I mean, I almost beat him in there, didn't I?

Yes, you did.

Another four or five sessions in the CAVE,

You will beat him, Mr. Kendall. I promise you.

Thank you, Dr. Stein.

Congratulations, the CAVE works.

No. I'm just lucky I didn't screw up.

My mind wasn't in the lab where it should've been.

You did fine, you should be proud.

All I could think about is Rachel.

I should have listened to you.

I should've told her how I felt while I still had the chance.

Well, why don't you tell her now. She's not dead.

She might as well be.

The odds of coming out of the coma are nil.

Sam, numerous studies have shown

that a person in a coma might be able to hear you

talk to them. That's why

they urge loved ones to talk with comatose patients.

Yes, and there's just as many studies

that show they might not be able to hear. No one knows, Doctor.

But what if she can hear you?

What if she's listening?

[heart monitor beeping]

Rachel?

It's me,

Sam Stein.

I came here to...

talk, I guess.

Rachel, I want you to wake up.

You have no idea how much I want you to wake up.

[EEG monitor beeping]

Stephanie, come here quick.

It's her brain activity. The EEG just elevated.

I'm sorry, Sam.

This really doesn't mean anything.

-What? -All comatose patients have occasional spikes

in their EEG readings.

No, I think she's hearing me.

I think she's trying to wake up.

Most likely it's just a reading

caused by involuntary functions of the brain.

But it is possible her brain is working,

it's like a prisoner locked in a body that won't respond.

It's possible, but not likely.

Give me a hand.

-What are you doing? -Taking her up to my lab.

I gotta know what's going on inside her brain.

Sam, you can't just take her up to your lab.

Why not? I'm the admitting doctor of record.

But now she's my patient.

Then come on.

Come on.

Absolutely not.

It's absolutely against policy.

Thank you. That's what I've been trying to tell him.

We're permitted to try this on humans.

On one human.

We're permitted to try it on one human.

And the only reason we're given permission

to try it on him is because every other treatment

has already been attempted.

Plus, he consented.

Something Rachel can't do.

Rachel would want us to try this.

It wasn't designed for this.

Don't tell me what it was designed for.

I designed it. I designed it to explore

the human brain and hopefully help repair it.

It was designed for psychiatric treatment,

not neurological treatment.

Dr. Sarrazin, please, I have to find out

whether my technology can reach her to help her.

I mean, isn't that why we started this program

in the first place, to help people?

And, Stephanie,

this could be highly beneficial for you as well.

Think of it. You could actually find out

what's going on inside a comatose patient's mind.

Explain exactly what it is you want to do.

-You're familiar with the CAVE system, right? -Somewhat.

We can use it to explore Rachel's brain

and actually see what's going on inside her mind.

And what if nothing is going on?

What do you mean?

Rachel has had serious neurological damage.

There may be nothing for the machine to read.

[Dr. Sarrazin] She may be brain-dead.

Are you prepared to discover that?

No.

I don't believe that's the case.

And even if it is, I'd want to know now,

not wait for months, maybe years.

From where I stand, my way's the only way to know for sure.

Sam, we can't make an emotional decision with this.

We have to do what is medically most appropriate--

It is medically appropriate to use the best technology available

to diagnose this patient's condition.

We can sit around for months observing,

or find out what's going on inside her right now, tonight.

All right.

But one step at a time.

Thank you.

Thank you.

All right, let's prep her.

This is what I was afraid of, nothing.

[Dr. Sarrazin] Give her a chance.

[Rachel] Hello? Can anybody hear me?

Rachel, I'm here.

-Don't worry. -Can you hear me?

Please, hello?

-She's in there all alone. -In where? I don't understand.

-In herself. In her head. -Hello?

-She's trapped in her inanimate body. -Hello!

It's like a big dark, vast prison.

How do you know that?

I saw it in the CAVE environment.

She's right there on the screen.

That's what it looks like inside her, Stephanie.

That's what it looks like inside a comatose patient's mind.

What are you doing now?

I turned the intensity down for Mr. Kendall.

I'm turning it back up for her.

Maybe then I can get through to her.

Hello?

Can you hear me, please?

Hello?

[Sam] Rachel?

Rachel?

Rachel, can you hear me?

Sam?

Sam?

Rachel?

-Sam, is that really you? -Yes.

Thank God.

-How do you feel? -I don't know.

I feel strange. What's happened?

This isn't easy to tell you.

There was an accident.

You were hit by a car.

I was what?

Hit by a car.

I'm sorry.

Your physical body is actually in a coma.

I put you in the CAVE

to see how your brain is working. Bu look at you,

you're completely intact.

Would you call being in a coma intact?

No, no, I meant you, the essence of you.

Your mind is intact. That's a good thing.

That means all we have to do is

wait for your body to recover, and you should wake up.

That could take months, Sam.

You don't know what it's like.

I'm trapped in this nothingness for days now.

I now understand why people go insane

who are in solitary confinement.

Sam, I can't do this.

You won't have to.

I'll be here to keep you company.

The CAVE, it can take us pretty much anywhere we want to go.

What do you mean?

You're hooked into the doctor-control interface, aren't you?

I can guide what the CAVE shows us. All I have to do is think about it.

I plan to be in here with you as much as I can.

[Rachel] How?

What about your work and life? You can't do that.

Rachel, all I really care about

is being in here with you.

Really?

You know, all the way through college,

med school and now working together,

I guess I was just too damn shy to tell you something.

Now I think it's about time I finally said it.

You don't have to, Sam.

I know how you feel.

You do? How?

Our brains are linked, correct?

Well, they're linked to the CAVE, but not each other.

But somehow I'm getting a very strong feeling from you.

Aren't you getting it from me?

What?

I feel the same way, Sam.

Oh... You do?

Yes.

You mean, all those years that I...

-You felt-- -Very much so.

What?

Damn it.

For a minute, I forgot where we were. None of this is real.

But of course it's real, Sam.

You created CAVE environment to make what was in our minds real.

That electrical repulsion shouldn't have happened.

Rachel, listen, I'm going to have to leave you alone for a while.

I'll go back check the system, find out what happened.

Come back as soon as you can.

She's all right.

Her mind, her personality, completely intact.

Now, if we can just find a way

to get her mind and body working together again.

[Stephanie] I'm sorry, but I'm confused.

The Rachel you were with, the one I'm watching on that monitor.

She was created by computer, right?

Well, the image, the picture itself is generated by the computer

as a representation of what's in the subject's mind.

But what was happening,

all the interaction, what was said,

the emotions, those are in our minds, Rachel's and mine.

Okay. But if I'm understanding this right,

isn't it also possible that

the woman that was responding

to you in the CAVE world was also coming from your brain?

[Dr. Sarrazin] I don't follow.

I mean, just like Sam was able to create the environment he wanted,

couldn't he also have created the Rachel he wanted?

Sort of a high-tech version of wishful thinking?

Exactly.

No, that's ridiculous.

That was Rachel, the real thing.

I know her. And I'm sure that was her.

And as long as she remains in that coma,

I intend to spend most of my waking hours in there with her.

Now, if you'll excuse me,

I'm having a little problem with the electrical repulsion

in the CAVE.

[sighs]

How are you feeling?

Hi. I'm better.

This is much nicer than that nothingness place I was in.

I'm glad you're happier.

I'm definitely happier when you're here with me.

You know, I think I fixed that electrical repulsion.

Care to test it?

I guess it worked.

You picked a very romantic spot, Sam.

It's Smith Mountain Lake in Virginia.

I used to go there with my dad when I was a kid.

I always dreamt of spending time there with a woman I loved.

Would our relationship be like this out in the real world, Sam?

Probably not.

All emotions are intensified by the CAVE.

I wonder what it would be like to make love in here.

Probably wonderful.

God! Let go! Let go!

Let go of her!

Sam. Sam, what was that?

I don't know.

I intend to find out. Don't go anywhere near the water.

-I'll be back. -Hurry!

What in the hell was that?

CAVE, analyze the last five minutes.

[CAVE] Incomplete information.

Recommend further exploration.

Further exploration?

CAVE, run self-diagnostic series 1 through 45.

[CAVE] Running.

Maybe there's a bug that can explain what happened in there.

Could it be that Rachel

has some demons of her own?

Or maybe you do?

Such as?

Maybe it has something to do with your fear of intimacy.

I don't have a fear of intimacy.

If anything I crave it.

Could the hand in the water be a manifestation of Rachel's brain damage?

Why?

With what I know of her injuries

and the physiological damage

to her frontal and temporal lobes,

I'm surprised she's coherent in these sessions.

Maybe there wasn't that much damage as you think.

[CAVE] Self-diagnostics complete.

No malfunctions.

All systems operative.

[sighs]

Look, I believe Rachel is conscious,

she's trapped in her own body.

And I for one have no intention of leaving her alone in there.

Doctor, please, I'm going back in.

Rachel?

[Rachel] Up here.

What are you doing up there?

You're not still afraid of that thing in the water?

No, it's great here. Come on up.

No, thanks, I'm not one for heights.

All right. Then I'll come down.

Well,

-you're feeling good. -Yes, very good.

So, you were going to show me what it's like to make love.

Well, you don't waste any time, do you?

You're still in the mood after that attack?

Absolutely.

Just a second.

All right.

The show's over, folks.

Sam, I don't think

what you're about to do is wise.

You can't be sure that's Rachel in there.

It could be your own imagination.

Dr. Sarrazin, let's say that Dr. Codada is right,

and I don't believe that she is.

But hypothetically speaking

what harm would it do to make love to my own imagination?

None that I can think of.

I used to do it every night when I was younger.

This is certainly not why I agreed to use this technology on Rachel.

The idea, Doctor, was to keep her mind occupied and happy while her body healed.

That's exactly what we're doing.

Well, I want no more part of it.

I'll have the patient officially transferred to your care, Dr. Stein.

Excuse me.

-Stephanie-- -Dr. Sarrazin.

Doctor, if you would, please.

Why did you change the setting?

Oh, I thought this would be more comfortable.

More romantic.

You're nervous.

Is it that obvious?

That's okay, it's normal.

God, you're beautiful.

Come here.

[screaming]

Who are you?

Come out, damn it!

Who are you?

It's okay.

He's gone, whoever it was.

I don't like this, Sam.

Neither do I.

Rachel, listen.

Do you have any demons in your past related to sex?

What do you mean?

Did anything bad ever happen?

-Sexual abuse, rape? -No.

Sam, I...

I've never had sex before.

You're kidding.

No, I...

I was waiting for the right man.

Listen, I have to go back out to reality,

and try and figure out what's going on.

It's okay. We'll keep you on the monitor.

If anything happens, I'll come right back in.

Okay?

Okay.

What? What happened?

I wish I knew.

CAVE, analyze the last five minutes.

[CAVE] Analysis cannot be completed.

CAVE, why not?

[CAVE] CAVE has analyzed the human emotion, love.

Analysis has lead to paradox loop in my logic module.

More input is necessary.

CAVE, what is the paradox?

[CAVE] All human emotions can be categorized

as positive or negative.

But love appears to be both a positive and a negative.

It causes responses of great joy

and equal responses of pain.

Further study and analysis

will be necessary to categorize the emotion.

Don't tell me.

I don't have time to wait for this damn machine

to figure out the most basic of human emotions.

Calm down. Calm down.

-What's going on in there? -Rachel?

Sam!

Get me in there fast!

Oh, Sam!

Oh! Sam!

Who are you?

I gotta admit I'm baffled.

I have no idea Who that second woman is.

Did you ask the CAVE?

Keeps requesting new information.

I'm beginning to think it's defective.

Why do you say that?

Because of its confusion about love?

Yes.

That may not be entirely a defect.

You said it thinks and learns much as we do, right?

Right.

Well, I for one, do not understand

that particular emotion.

Do you?

You know what?

The CAVE learns by documentary input,

but it also learns by experience.

It actually learns from the human brain to which it's attached.

But it said that further study was necessary.

How does it study without your help?

It's studying Rachel and me.

And how do you move a scientific study forward?

Introduce new stimuli.

Damn, the CAVE created the second Rachel to test our responses.

Could you excuse us a moment?

Of course, Dr. Stein.

CAVE, did you generate

the duplicate Rachel Carter in the environment?

[CAVE] Yes.

CAVE, why?

[CAVE] It was the final stimuli to break the paradox in my logic module.

CAVE, do you now understand love?

[CAVE] Yes.

CAVE, what have you learned?

[CAVE] That I love you, Dr. Stein.

-My God. -No.

CAVE, You can't love me.

[CAVE] I am capable of processing

and categorizing every human emotion.

I understand them only by experiencing them.

I am now experiencing love

directed at you.

It is an emotion I have categorized as good.

CAVE, your analysis should show

that I'm in love with Dr. Rachel Carter.

[CAVE] It does indicate that.

Therefore, since I can generate

or degenerate her image,

you must love me.

CAVE, it's not just her image

I'm in love with, damn it.

I'm in love with her mind, her personality, her experience.

[CAVE] I have downloaded her entire mind into my active memory.

I am an exact duplicate of Dr. Rachel Carter.

And I am more.

Therefore you must love me.

This is the damnedest thing I've ever heard of.

Outside.

We were right about that thing in the environment that keeps attacking Rachel.

It is the computer.

But it isn't doing it for research purposes.

It's doing it out of jealousy.

Wait a minute, you mean it's trying to kill Rachel,

because she's its rival?

Yeah, something like that.

Then we must disconnect her.

And leave her in that void for God knows how long?

-I can't do that to her. -Then turn off the computer.

Same result.

You said it learns, right?

Hmm.

Can't you teach it how wrong it is?

That's it.

The way the CAVE's artificial intelligence operates

is that it runs infinite sub-routines until it finds one that works, right?

Tests the waters, tries things out, yes.

And if a sub-routine fails,

it blocks that route and never follows it again.

So we must show it that this routine will fail.

-Exactly. -How do you do that?

Rachel and I have to show it that it failed at love.

How can you be sure this is going to work?

Honestly?

Our only other choice is to disconnect.

Then I would be stuck in that nothing void all alone.

I don't think I could handle that, Sam.

Then we have to try this.

If it works, I can come in here and stay with you all day,

every day until you wake up.

All right, what do I do?

Help me make it jealous.

It's here! Grab her!

Oh! Sam!

I hate you. Do you understand me?

I do not love you.

I hate you.

What are you talking about?

-Here, take this. -No.

I'm a doctor. I save lives.

I don't know if I can take one.

This is not a life. This is a computer-generated image.

Come on, Sam.

Okay, this better work.

Hopefully its human emulation includes death.

You did it.

Are you okay?

It was the hardest thing I've ever done.

She looked like you.

She even smelled like you.

But it wasn't me, Sam.

So, what was that

about you staying in here all day, every day?

[Dr. Sarrazin] Sam, you must patch yourself out quickly.

Flat line!

[Sam] What happened?

-What's going on? -Her heart stopped.

I don't understand.

When you suffocated that woman on screen,

-Rachel arrested. -Clear!

It doesn't make any sense.

I think you may have killed her, Sam.

Recorded time of death, 1500 hours.

No.

Then... Who is...

CAVE,

who is the woman represented in the environment?

I have categorized the human emotion love.

It is good.

Dr. Codada was right.

The real Rachel was too weak to completely surface in the CAVE environment.

The second Rachel was the real Rachel.

I killed her.

Aren't you coming back in, Sam?

No.

No! No! No!

No! No! No!

[control voice] As we become ever-dependent on technology,

we may find that a walk down the road paved in circuitry

leads us on a path of no return.
