[ muffled screaming ]

[ muffled ] Help!

[ fires ]Man: uhh.

[ starts engine ]

[ upbeat pop music plays ]

[ music ends ]

Wake up, ladies.

Sam sanford, bright and cheery On a wednesday morning.

Got something on your mind You want to get off your chest?

Give me a call. The lines are open.

[ telephone beeps ]

Okay, our first caller.

Okay, lady, You're on the air.

What's on your mind?

Woman: listen carefully And do not interrupt me.

The son of byong sunahara Has been kidnapped

And is being held In an airtight capsule

With a limited supply Of oxygen.

Unless $1.5 million Is paid for his release,

Tadashi sunahara Will suffocate

In exactly 52 hours.

L.P., run a standby tape, Please, fast.

Instructions Regarding payment are

On the coffee table Of the sunahara home.

Okay, officer, Get them out of here.

What have we got, Danno?

The kidnapped boy

Is the son of one of japan's Leading industrialists.

The family's Been vacationing here.

Well, we'll get a call From the state department.

You can bet on it.

Apparently, the house boy Caught the kidnappers

In the act.

He also caught one In the back.

Who else was in the house?

Only the mother. The father's In hilo on business.

We found her unconscious.

Doc bergman's with her now.

Here's the ransom note, Steve.

As you can see, It's dime store stationery.

They want us to communicate With them on k-poi radio,

Tomorrow at 12:30.

How did they make Their initial contact?

By telephone On a live radio talk show.

A woman's voice.

We've arranged To trace their next call.

A woman? Huh.

I'd like a tape of Her conversation, danno.

Right.

I see they want The ransom money

Dropped off at sand island Outflow point

9:30 a.M. Friday At water's edge.

Let's get a complete set Of maps of the area,

And station a man there Round-the-clock

To monitor Any advance activities.

Right.

Chin ho: steve?

Looks like they Approached in a boat.

You can see where They put it up on the beach.

There are two sets Of footprints.

Let's get photographs And plaster casts

Of the footprints, chin.

Check with the neighbors.

See if anyone heard a shot Or saw a boat.

Right.

Doc?

How is she?

She'll be okay.

Probably be a little nauseous When she comes to.

I found this piece of gauze Saturated with some anesthetic.

I don't recognize it.

Wow.

Boy, that's potent stuff.

Get it to the lab.

See if che can find out What it is.

Right.

Hurry it up, Will you?

Look, I'll only be Just a minute, all right?

Mankind's salvation will not be Found in the stars.

Millions of years ago, Man crawled out of the sea.

Now, it is time to think Of returning to it once again.

I left the space program

Shortly after the first Successful mercury mission,

Because I realized then

That all the knowledge Gained from space exploration

Will be of very much use

To island countries such as Japan, indonesia, and britain,

When their populations explode And they run out of land.

When that day comes, As it obviously must,

Mankind must develop The technology

To build underwater cities

That can house these teeming Populations of the future.

But before science Can attack theseproblems,

Man must be made to see

The absolute necessity For the research,

For the funding of --

Oh, I've run overtime.

Sorry about that.

That'll be all for the day.

Well?

It didn't go well.

What?

A servant came in.

Asuko shot him.

I think he's dead.

Paul, no. But you assured me --

You assured me there would be No shooting, no violence.

Philip -- philip, It wasn't planned.

It was the only way To get the boy.

But murder?

No, I'd-I'd rather We abandon the whole plan.

It was too late to turn back.

Look, philip...

I regret this as much as you,

But what has happened is done.

Try and remember what we -- What we have to gain --

The money that we've needed For so long.

The money to start The experiments.

Philip, asuko's Waiting for me outside.

I'll call you later.

Try not to worry.

My primary concern, jonathan, Is for the boy's safety.

Jonathan: And so is mine.

It's a matter of how The problem is approached.

Any attempt to track down The kidnappers

Before the boy is returned Could trigger a rash response.

May I remind you that they Have already killed one man?

There is no reason for them To spare the life of the boy,

Especially if he's seen them And can identify them.

Steve, I'm only Urging caution.

Jonathan, we will exercise Caution. Don't worry.

But if we sit by and let these Murderers call the shots,

It will be an open invitation

To every criminal In the islands.

Keep me posted.

Count on it.

How is the, uh --

How's the weather In washington?

Raining.

Why don't you come to hawaii And get a little sun?

You get the boy, I'll be there.

Good.

I spoke to a neighbor Who reported hearing

An outboard motor At about 5:30 this morning.

And no gunshots?

No. Neither did Anyone else in the area.

He must have used A silencer.

When is the boy's father Due here?

He's on his way now. Duke is Waiting at the airport.

Let's hear the tape.

Asuko's voice: Listen carefully

And do not interrupt me.

The son of byong sunahara Has been kidnapped

And is being held In an airtight capsule

With a limited supply Of oxygen.

Unless $1.5 million Is paid for his release --

That's it.

Chin, send a copy Of that tape

To the bureau In washington.

Maybe they have a matching Voiceprint in their files.

Tolvar worries me, Paul.

I don't think He can take pressure.

Look, philip Will be all right.

I know him. I know him very well.

[ sigh ]

I've worked with him.

I ought to know.

You make sure! Huh?

Because we're going to Need him later.

You know, I mean, after The money's been paid.

[ sigh ]

Look, asuko, He is in it already.

He designed the capsule, Didn't he?

[ quietly ] Yes.

He's in it All the way.

I know.

Thanks to you, paul.

Okay?

[ exhales ]

Shigemi.

What are you doing here?

Came to see if you're okay.

I'm all right.

Everything is going As planned.

Tolvar -- how did he take The shooting of the servant?

He's accepted it.

And colburn?

There's no problem.

You're sure?

He's a means To an end, shigemi.

I like him, but that Won't stand in the way

Of what we have to do.

I'll see you In a few hours, asuko.

The chemical from the gauze Used on mrs. Sunahara

Was made from a lionfish.

A lionfish? What's a lionfish?

One of the most beautiful Fish in the world,

And one of the most deadly.

Would the venom from one fish Be strong enough?

It could be fatal.

But this mixture worked Through the respiratory system.

It was distilled from venom Of four or five fish,

Then cut with a buffer.

A catalyst induced The anesthetizing vapors.

That's a first for me.

Chin, check with the tropical Fish places around the island.

See if anyone bought an unusual Number of lionfish recently.

Okay.

Che, the ransom message said That the boy was being held

In a capsule with a limited Supply of oxygen.

Does that suggest Anything to you?

It suggests that The capsule is isolated,

Perhaps underground Or underwater.

And a limited supply of oxygen

Would suggest air tanks.

How long would one standard Tank last, for instance?

A standard diving tank

Of 2,000 pounds of pressure Per square inch

Would last half-hour To 45 minutes,

Depending upon depth And breathing consumption.

We'll say a half-hour. That would be 2 an hour.

Times 52 would be 104 tanks. That's not likely.

Could the pressure Be increased

To get between 5 and 10 Hours out of each tank?

They would have to Be specially built

To withstand Extremely high pressure.

But if they were Specially built,

They wouldn't be hard To trace, would they?

Danno, check the local Dive shops.

Get as much help as you need. We've got to move fast.

Can I help you?

Five-o.

We're trying to locate a man

Who might have bought a large Number of lionfish recently.

I haven't sold any For six months.

They're too easy to come by.

Any diver Worth his weight in salt

Can get them right Off bamboo ridge at cocoa head.

Thank you.

Sure. About a week ago.

Strangest-looking tanks I ever saw.

I asked him What they were for,

And all he said Was "Special dive."

But they were okay.

The regulators And all were legal.

Something happen to him?

How many tanks did he have?

Uh, six.

How big were they?

Phew. Big.

About 5 foot.

Took 3,500 psi apiece. 1/4-inch-thick tank walls.

I never seen Anything like it.

Do you have the guy's name?

Yeah, I should have it.

Oh, here it is.

Doesn't live far From here, either.

Paul colburn.

Did he show you proper Identification to verify it?

Sure. Had to. It's a state law.

You got to record Each refill.

Thanks a lot.

Uh-huh.

Mr. Colburn's apartment Is upstairs,

But I don't know What you want with him.

He's a nice man.

We'd just like To look inside, please.

Well, I don't think I could do that.

I don't like To disturb my tenants.

Madam, This is a search warrant

Authorizing us To enter his apartment.

Now, I'd prefer Not to break the door down.

No, no, that won't be Necessary...

I'll take the key.

Not if It's that important.

Step over there, please.

Huh.

Steve, lionfish.

Lionfish.

What's mr. Colburn done?

We don't know yet. Can you tell us where he works?

He's an assistant professor At the oahu pacific institute.

We'll need a complete Description of him.

He's slender, Very nice-looking.

Always polite. Never gives me any trouble.

Pays his rent on time. Never brings any girls here.

That's a character reference.

How tall is he? What's his age?

Is he caucasian? Color of his hair?

He's blond, about 6 foot.

Why, there's Mr. Colburn now.

Officer, stop that man!

Let's go, danno.

I lost him, sir.

Okay, danno, Put out an apb

On mr. Colburn, "A nice man."

[ knock-knock ]Yeah, come in.

We're looking for some Information on paul colburn.

I understand He's one of your associates.

Uh, yes, we are working Together on a project.

How well do you know him?

We've been associated For some time.

He was originally a student In one of my classes.

When was the last time You saw him?

Why are you looking for him?

We have some questions To ask him.

Well, I hope He's not in trouble.

All right.

Now, tell me, what happened?

There were police cars In front of my building.

They were just standing there, Waiting for me.

That future generations will Have to move into the sea?

Right. Tolvar says he doesn't Know much about him.

Most of it came from An interview he gave

To the university newspaper When he first arrived.

Stay on it, danno. Colburn's in this thing.

I'm a little cold, Father, but...

But I am all right.

You are not alone.

Your mother and I Are with you.

Steve, their signal

Is coming from somewhere Around fort derussy.

When do you think I can come home?

Cars 5, 12, and 15,

Proceed immediately To fort derussy.

Silent approach.

Mcgarrett: repeat, Silent approach.

Danno, Do you read me?

The signal could be coming From somewhere

From your immediate area.

Now, we can't pinpoint it yet, But get ready to move.

Steve, we're boxed in Heavy.

Make an end run or something, But get out of there.

[ tires screech ]

Chin ho: we're clear, steve.

Steve, something's wrong.

I can't contact Truck number three.

I can't get an exact Position on them.

We need that third leg to get An accurate fix, victor.

Now keep after it.

Be brave, tadashi.

Everything Will be all right.

We are going to have you home Very, very soon.

I am trying To be brave, father.

Man #3: the antenna's stuck.

Wait, I think It's turning now.

Yes, it's working.

I read a position On kanai street.

All cars, proceed Immediately to kanai road.

Kanai road. Danno, can you read me?

Yes, steve.

The location is not More than two miles

From where you are now.

Tadashi: father, I am under--

[ radio clicks ]

Asuko: the money is to be Delivered by byong sunahara

At 9:30 tomorrow morning On sand island

At the outflow point.

Any departure from These instructions

Will mean death to tadashi.

[ click ]

Tadashi -- tadashi...

[ speaking japanese ]

[ speaking japanese ]

It's a radio relay Setup, steve.

It receives incoming signals On one frequency

And transmits them On another.

Unfortunately, we were Monitoring only one signal --

The wrong one.

But how did sunahara Talk to his son?

Well, the kidnappers Must have had the radio

In the capsule set up So that they could

Turn it off and on By remote control.

Does the equipment Tell us anything else, che?

Yes. Judging from The strength of the signal,

We can make A rough assumption

That the capsule is within 8 miles of the shed.

Okay, let's assume That this mark is the shed.

An 8-mile radius...

Would be a circle...

Like that.

It takes weeks to cover That entire area.

Months, danno, months.

And we've only got hours.

Okay, let's review The facts once again.

One -- we can assume From the evidence

That the kidnappers arrived At the sunahara home by boat

And left the same way.

Two --

One week Before the kidnapping,

Colburn filled six custom-made Tanks with compressed air.

Three -- colburn Is studying oceanography.

And four -- The boy's last words

Were, "Father, I am under--" Under.

So I think the conclusion Is pretty obvious.

The capsule's underwater.

Right.

The next question is Where is the capsule?

The only section of the ocean

That is within an 8-mile Radius of the shed

Is this area right here.

So the boy must be In the bay off sand island.

Should we call harbor patrol And sweep that area?

No, I don't think so, chin. It's too dangerous.

If, uh -- if we don't Find the boy

And the kidnappers Spot us doing it,

It's goodbye for the boy.

But call harbor patrol Anyway

And ask them to stand by In case we need them.

Get me commander fredericks In the coast guard, please.

[ radio beeps ]

Cape corwin.

Mcgarrett To commander fredericks.

Stand by.

Commander fredericks, Mcgarrett.

Commander fredericks.

Commander, the kidnappers Want the money

Left at the water's edge,

But, you know, They won't go near it

If they know They're being observed.

So, how sensitive Is the electronic equipment

That you have for monitoring Such an operation?

We have some new Electronic equipment

That should do the job.

You know, it's possible That they'll use a scuba diver

To pick up the money.

This equipment can Monitor his heartbeat.

Good, commander. That's Exactly what we need.

We're glad to help.

I'll have the ship Positioned by 0600.

Thank you, sir.

If they use a diver, You could rendezvous

With a car on one Of those back roads.

Yeah, that's A good thought, danno.

Let's stakeout all The surrounding roads.

But I don't want Anyone to move in

Until I give the order.

Steve, that tape we sent To the bureau in washington --

They found a voiceprint That matches.

It belonged to a woman Named asuko sunata,

A member of a japanese Terrorist group

That calls itself The "Red army."

Didn't you say that Colburn had been in japan?

Yeah, two years ago, Doing graduate work.

Yeah, well, That's it, danno.

That's the connection.

Well, on his record,

I can't see colburn As a terrorist.

Well, you can forget About past records.

Let's quit, gentlemen.

It's been a long day. Get some rest.

You brief the men, Danno,

And I'll meet you At 6:00 a.M.

[ air sprays ]

[ knock on door ]

[ knock on door ]

Yeah?

Paul, it's philip.

What are you doing here?

Where is asuko?

Well, I'm meeting her Later.

Why did you come?

Paul, I've got To talk to you.

This thing has gone too far. We must release the boy.

Release the boy?

We're close To getting the money.

At what cost?

A man has been killed,

And I am not sure We can trust asuko.

Look, asuko has The same goals as we do,

But perhaps a different Way of achieving them.

Are you sure?

I'm sure.

You just be ready To meet us in the morning.

Nothing will happen To the boy.

I promise you that, philip.

Einstein once said,

"Mankind's great problem Is a perfection of means,

But a confusion of ends."

It's been quiet All evening, sir.

I'll get the back roads Staked out.

You two officers Come with me.

This is mcgarrett.

Patch me through To commander fredericks

At the cape corwin, please.

Man: mcgarrett Calling cape corwin.

Come in, mcgarrett.

Commander, any action?

Nothing, so far.

We're standing by If you see or hear anything.

Roger.

Mr. Sunahara.

We have evidence that this Operation is being conducted

By a radical Japanese organization.

I'm afraid there might be An assassination attempt

On you after The exchange is made.

Now, mr. Sang li here

Is a police specialist Trained in this sort of work.

He'll be glad to take Your place if you wish.

Mr. Mcgarrett, I appreciate Your concern for my safety,

But I would not risk My son's life by a deception,

Nor will I allow anyone

To jeopardize their life For mine.

Well, I don't consider it A deception,

But I understand your decision And I'll abide by it.

All right, gentlemen, Let's go.

[ radar beeping ]

Cape corwin to mcgarrett.

Yeah, go ahead, Commander.

Mcgarrett, we've picked up A small craft

Approximately 6 miles West of your position

Moving east at a high speed.

Very well, commander. Thank you.

Keep me posted.

[ beeping ]

Cape corwin to mcgarrett.

Mcgarrett.

We've picked up a diver Heading towards sand island.

Don't fire Unless I order it.

Fredericks: cape corwin To mcgarrett.

He's dropped the sled.

Thank you, commander.

There is your money.

Where is my son?

Do not harm my son.

I have done What you asked.

Don't worry. Your boy's okay.

You'll be told Where to find him

Before the 52 hours is up.

Cape corwin to mcgarrett.

We've picked up the diver. He's headed towards the boat.

[ gunshot ]

[ radar beeping ]

What's the current position Of the boat, commander?

Heading towards Diamond head.

You think we could Intercept?

Negative. Too late.

All right, let's make A sweep.

You'll have to check Every buoy and mooring

In the harbor.

Right. Come up to 0-8-0.

Danno, let's go.

Gentlemen, take mr. Sunahara Home, please.

[ engine starts ]

Well?

As planned.

Commander fredericks To mcgarrett.

Yes, mcgarrett. Come in, commander.

Thank you, commander. We're on it.

We'll handle it.

By a dr. Philip tolvar.

That's the missing piece We've been waiting for.

He also checked out The institute's airplane.

Let this be a warning To all members

Of japan's imperialist Ruling class.
