Thank you.

Wake up, ladies.

Sam Sanford, bright and cheery on a Wednesday morning.

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

Give me a call. The lines are open.

Okay, our first caller.

Okay, lady, you're on the air. What's on your mind?

Listen carefully.

in an airtight capsule with a limited supply of oxygen.

Unless $1.5 million is paid for his release,

Tadashi Tsunahara will suffocate in exactly 50 hours. LP, run a standby

tape, please, fast. Instructions regarding payment are on the coffee

table of Tsunahara Homes.

Okay, officer, get them out of here.

What do we got, Dano?

Kidnapped boy is the son of one of Japan's leading industrialists.

Family's been vacationing here.

Well, we'll get a call from the State Department.

We 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.

Father's in Hilo on business.

We found her unconscious.

Doc Bergman is with her now.

Here's a ransom note, Steve. As you can see, it's dime store stationery.

They want us to communicate with them on Cape Hoy radio tomorrow at 12.30.

How do they make their initial contact?

By telephone on a live radio talk show.

A woman's voice.

We've arranged a trace of their next call.

A woman?

Huh.

I'd like a tape of her conversation down.

I see they want the ransom money dropped off at Sand Island Outflow Point, 9.30 a

.m. Friday at Water's Edge.

Okay, let's get a complete set of maps of the area and station a man there

around the clock to monitor any advance activities.

Right.

Steve.

Looks like they approached in a boat. You can see where they put it up on a

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.

Found this piece of gauze saturated with some kind of anesthetic. I don't

recognize it.

Wow.

It's potent stuff.

Get it to the lab. See if Che can find out what it is. Right.

Hurry it up, will ya?

It'll only be just a minute, all right?

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

Millions of years ago, men 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.

But 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 these problems, men must be made to see the

absolute necessity for the research, for the funding of... Oh,

I've run over time.

Sorry about that.

That'll be all for the day.

It didn't go well.

What? A servant came in.

Asuko shot him. I think he's dead.

Oh, no.

But you assured me. You assured me there'd be no shooting, no violence.

Philip, it wasn't planned. It was the only way to get the boy.

But murder.

No, I'd rather we abandon the whole plan.

It was too late to turn back.

I regret this as much as you, but what has happened is done.

Try and remember what we have to gain, the money that we've needed for so long,

the money to start the experiments.

Philip, Asuko is waiting for me outside.

I'll call you later.

My primary concern, Jonathan, is for the boy's safety.

And so is mine.

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

Any attempt to track down the kidnappers before the boys return could trigger a

rash response.

May I remind you, sir, that they have already killed one man. There is no

reason for them now to spare the life of a 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 gunshot? No, neither did anyone else in the area.

He must have used a silencer. Yeah. When is the boy's father due here? He's on

his way now. Duke's waiting at the airport.

Let's hear the tape.

Send a copy of that tape to the bureau in Washington.

Maybe they have a matching voice print 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.

I've worked with him.

I ought to know. You make sure.

Because we're going to need him later.

You know, after the money's been paid.

Look, Asuko, he is in it already.

He designed the capsule, didn't he?

He's in it all the way.

Thanks to you, Paul.

Shigemi.

What are you doing here?

Came to see if you're okay.

I'm all right.

Everything is going as planned.

Tolvar, how'd he take the shooting of the servant?

He's accepted it.

And Coburn?

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.

Chemical from the guards used on Mrs.

Tsunahara 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?

Could be fatal.

But this mixture worked through the respiratory system.

It was distilled from the venom of four or five fish and then cut with a buffer.

A catalyst induced the anesthetizing vapors.

That's a first for me.

Chen, 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 a

half hour to 45 minutes, depending upon... depth, and breathing

consumption. Well, say a half hour.

It'd be 2 an hour times 52. It'd be 104 tanks. That's not likely.

Could the pressure be increased to get, say, between 5 and 10 hours out of each

tank? Yes, but they'd have to be specially built to withstand the

extremely high pressure. But if they were specially built, they wouldn't be

hard to trace, would they?

Tano, check the local dive shops.

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

Can I help you?

Five-0.

We're trying to locate a man who might have bought a large number of lionfish

recently. I haven't sold any lionfish 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.

They were okay.

I mean, the regulators and all were legal.

Something happened to him? How many tanks did he have?

Six. How big were they?

Big. About five foot.

Took 3,500 PSI apiece. Quarter inch thick tank walls.

I never seen anything like it.

Do you have the guy's name?

Yeah, I should have it.

Here it is.

Doesn't live far from here either.

Paul Colburn.

Did he show you a proper identification to verify it? Sure. Had to. It's a state

law. You got to record each refill.

Thanks a lot.

Mr.

Colburn's apartment is upstairs.

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

He's a nice man.

He just likes 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.

Not if it's that important.

Steve.

Lionfish.

Lionfish?

What's Mr. Coburn done?

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

He's an assistant professor at the Oahu Civic Institute.

Very smart.

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, not a description.

How tall is he? What's his age? Is he Caucasian? What's the color of his hair?

He's blonde.

About six foot.

Where is Mr. Colburn now?

Officer, stop that man!

Let's go.

I lost him, sir.

Okay, Denno. Put out an APB on Mr. Corbin, that nice man.

My name is Dan Williams, Hawaii 50.

Oh, yes, Mr. Williams.

What can I do for you?

We're looking for some information on Paul Colburn.

I understand he's one of your associates.

Yes, we are working together on a project.

How well do you know him?

Well, 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?

I don't know.

A few days ago.

Why are you looking for him?

We have some questions to ask him.

Well, I hope he's not in trouble.

If you see him or hear from him, call this number immediately.

Will there be anything else, Mr. Williams?

No, no, Doctor. Just make sure you contact us if you ever.

Yes, yes, of course.

Who is it? It's Paul

There were police cars in front of my building.

They were just standing there waiting for me.

They saw me. I was lucky to get away.

Don't worry, Paul.

I mean, everything will go the way we want it to.

Everything.

Yeah, Nana. What do you got? Got a readout on Coburn.

Age 29, native Californian, graduate University of California at Berkeley,

top student.

Spent about a year in Japan doing some graduate work. Came to the islands about

a year ago.

What's he doing here?

He's working with Dr. Philip Tovar at the Wild Pacific Institute.

Tovar. Tovar. Isn't he the scientist who predicts that future generations will

have to move into the sea?

Right. Tovar says he doesn't know much about them, but I have the Institute

staked out just in case.

Where did you get this information?

Most of it came from an interview he gave to the university newspaper when he

first arrived.

Stay on it, Dano. Coleman's in this studio.

Yes? Mr. Tsunahara is here.

What do you say to a man whose son has just been kidnapped?

I don't know, Steve.

Send him in, please.

Mr. Tsunahara, this is lawyer Mr. Matsuda. Mr. Steve McGarrett.

Come in, please. Sit down.

Tell me, do you have any word for me on my son?

I'm afraid there's nothing new, Mr. Tsunahara.

But we're scheduled to communicate with the kidnappers tomorrow.

They want an answer to their demands.

I am prepared to pay the ransom,

Mr. McGarrett. But with one stipulation.

I wish to hear the voice of my son.

If he's alive, I will gladly pay any amount.

But if he's dead, I will not pay tribute to his murderers.

Well, I can see nothing wrong with that request.

Your message will be relayed. Thank you.

And now I would like to see my wife.

Of course.

Duke, will you escort Mr. Sunahara to the hospital, please?

I hope your wife is doing well. We'll keep in constant touch with you.

Good morning. This is Sam Sanford. I have a message for the kidnappers of

Tadashi Sunahara.

Mr. Sunahara will not...

Mr. Tsunahara will not deal with the kidnappers until he has spoken with his

son. Now, the lines to this station are open for a reply.

KPOI radio.

I wish to speak to Mr. Sam Sanford. I have a message from the kidnappers.

Sanford speaking.

Mr. Sunahara may hold his desired conversation with his son over Citizen

Band 3 at 4.30 this afternoon if he will show his good faith by calling off the

running dogs.

But be warned, Mr.

Sunahara will never speak with his son again if 5-0 continues to pursue us.

Hello.

Not enough time, Danny.

I think Mr. Sunahara will get his wish and talk to his son today at 4.30.

Thanks, Sam.

How's it going?

I'm checking the positions now, Steve.

Truck number one, report your position.

Truck number one in position at Pearl City.

Check. Truck number two, report your position.

Truck number two in position, Kamehameha Heights.

Antenna operative.

Truck number three, please report your position.

Truck number three in position at Punchbowl.

All trucks in position, Steve. Thank you.

Mr. Sotomayor, may I remind you, sir, to try to keep your son on the line as long

as possible. This may be the one and only chance we have to trace his

location. I understand.

Good. Step inside, please.

This is the microphone. Sit down.

Now, I'll signal you when we're ready.

Okay, roll the tape.

Let me know.

Ready.

Go.

Tadashi.

Tadashi. This is your father.

Speak to me, please.

Father? Father, I can hear you.

Can you hear me, Father?

Saraji, are you hurt?

Are they hurting you?

No, Father.

I am alone.

Then you are all right, my son. One line, honestly.

Steve, the signal is coming from somewhere around Fort Darussi.

Cars 5, 12, and 15, proceed immediately to Fort Darussi. Silent approach.

Repeat, silent approach.

Dano, do you read me? The signal could be coming somewhere from your immediate

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

Steve, we're boxed in heavy.

We'll make an end run or something, but get out of there, Dano.

We're clear, Steve.

Steve, something's wrong.

I can't contact truck number three. I can't get an exact position on it. 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.

The antenna's stuck.

Wait, I think it's turning now. Yes, it's working.

I read a position on Kenai Street.

All cars proceed immediately to Kenai Road.

Kanai Road.

Dano, can you read me?

Yes, Steve.

The location is not more than two miles from where you are now.

Father, I am under... The money is to be delivered by Bayoung Sunahara at 9

.30 tomorrow morning on Sand Island at the outflow point.

Any departure from these instructions will mean death to Tadashi.

I'll do my best.

It's a radio relay setup, Steve.

It receives incoming signals on one frequency and transmits them on another.

Unfortunately, we're monitoring only one signal, the wrong one.

But how did Tsunahara talk to his son?

Well, the kidnappers must have had the radio and the capsule set up so that

they could turn it off and on by remote control.

Does the equipment tell us anything else, Jay?

Yes. Judging from the strength of the signal, we can make a rough assumption

that the capsule is within eight miles of the shed.

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

An eight-mile radius would be a circle...

like that.

Takes weeks to cover that entire area. Months, Dano.

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, Coburn filled six custom-made tanks with

compressed air. Three, Coburn is studying oceanography. And four,

the boys' last words were, Father...

I am under, under.

So I think the conclusion is pretty obvious.

Capsule's underwater.

Right.

Next question is, where is the capsule?

The only section of the ocean that is within an eight-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, Chen.

It's too dangerous.

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 of the Coast Guard, please.

Cape Corn.

McGarrett for 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 not only pick up a diver, it can even monitor his

heartbeat. Good. Good, Commander. That's exactly what we need.

All of the ship positioned by 0600.

Thank you, sir.

They do use a diver.

He could rendezvous with a car on one of those back roads.

Yeah, that's a good thought, Denner.

Let's stake out all the surrounding roads, but I don't want anyone to move

in until I give the order. Steve, that tape was sent to the Bureau in

Washington. They found a voice print that matches.

It belonged to a woman named Atsuko Tsunada, a member of a Japanese

terrorist group that calls itself the Red Army.

Wait a minute.

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

Yeah, two years ago, doing graduate work.

Yeah, well, that's it, Dano.

That's the connection.

Well, on his record, I can't see Colburn as a terrorist.

Oh, well, you can forget about past records.

Let's quit, gentlemen.

It's been a long day.

Get some rest.

You brief the men, Dano.

And I'll meet you at 6 AM.

Yeah? Paul, it's Philip.

Philip, what are you doing here?

Where's Izuku?

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. I don't know what's going to happen next, and I am

not sure we can trust Izuku.

Look, Izuku has the same goals as we do.

but perhaps a different way of achieving them. Are you sure?

I'm sure.

Can't 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 of the Cape Corwin.

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. Tsunahara?

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. Seng Lee here is a police specialist trained in

this sort of work.

And 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.

Kick Corwin to McGarrett.

Yeah, go ahead, Commander.

McGarrett, we've picked up a small craft approximately six miles west of your

position, moving east at a high rate of speed.

Very well, Commander.

Thank you. Keep me posted.

Cape Corman to McGarrett.

McGarrett. We've just picked up a diver heading towards Sand Island.

Right on schedule, Commander. Thank you.

They're on their way.

Better get down there.

Take your position.

Don't fire unless I order it.

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.

McGarrett. Steve, we picked up the diver. He's headed towards the boat.

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 080.

Dano, let's go.

Gentlemen, take Mr. Sanahara home, please.

Well? It's planned.

Commander Fredericks to McGarrett.

Yes, McGarrett. Come in, Commander.

Steve, we've tracked the boat.

It's under the Sand Island Bridge.

Thank you, Commander. We're on it. We'll handle it.

There's something up there.

There it is.

Find out who signed this boat out.

General, William speaking.

Match me to the Oahu Pacific Institute.

10-4.

This is Officer Williams of Hawaii 5-0. We found an abandoned boat belonging to

you next to the bridge on Sand Island.

We'd like to know who signed that boat out today.

Chen, give me a progress report.

Nothing yet, Steve.

But we've got seven frogmen working.

Chen, we've got one hour of air left.

Now, press on it. Keep me posted.

Will do, Steve.

Steve, the boat was checked out by Dr.

Philip Tovar.

That's the missing piece, Dano. That's what we've been waiting for.

And guess what? He also checked out the Institute's airplane.

Oh, he's been busy, hasn't he?

Where do they keep the plane?

The old airport, Lagoon Drive.

Let's go.

Thank you.

Sam Sanford speaking.

You're on the air.

Tadashi Tsunahara will die for the sins of his family.

Let this be a warning to all members of Japan's imperialist ruling class.

Liberation is at hand.

The Red Army will prevail.

have an exact location for the plane down? Yeah, the Institute keeps it

hangar at a 210 Lagoon Drive.

Call the FAA and see if you can get an identifying number of the aircraft.

Then alert HPD that I want a full tactical squad at that location

immediately. Central, this is William.

Under buoy 1-1-3-4-H.

1-1-3-4-H.

Chin. She get me? Hurry up. Take off now.

Chin, do you read me? Come in.

Read you, Steve.

The capsule is under buoy 1-1-3-4-H.

Repeat. 1-1-3-4-H.

11-34-H. 1-1-3-4-Hotel.

Bridge, Vance. Give me a course to 41134 Hotel.

Tactical Squad, they're getting away.

Yes, Chin. Come in.

We got him, Steve.

He's all right.

Good work, Chin.

Good work. I'll notify his parents.
