Original subtitles

This was a neutral country during World War II.

There's a space behind this wall.

I'm going to hand this down to you.

This camera, GoPro. Can you get down there?

There's one simple question that I would really

like answered:

why aren't we being told the truth?

We came looking for the footprints of Adolf Hitler

and his escape through Spain.

Is that a swastika carved down there?

And I think we pretty much found them.

male narrator: In 2014, an executive order

declassified over 700 pages of secret FBI documents,

revealing that the U.S. government

was investigating Adolf Hitler's whereabouts

months and years after he was believed dead.

In these files, there are thousands of leads.

This is report... after report...

after report.

They had an active investigation looking for this guy.

narrator: Bob Baer, 21-year CIA veteran

and one of the most renowned intelligence minds

in the world, has reopened a 70-year-old cold case,

the death of Adolf Hitler.

All the witnesses are dead. There's no fingerprints.

There's no decent forensics.

It's the biggest mystery of the 20th century.

narrator: Armed with newly declassified FBI documents

and the most cutting-edge technology,

Bob has assembled a team of the most respected experts

in the world to carry out an international investigation.

We are not gonna make our conclusions in advance.

I just want to do the definitive investigation

on Hitler, for once and all, settle this damn thing.

All the evidence we have suggests to me

that Hitler could have made it to the airport.

narrator: Bob Baer

and war crimes investigator John Cencich,

focus their investigation

on Hitler's possible escape from Berlin.

You've got all these people leaving on the 21st.

Eight to nine airplanes

he could have gotten out in this mass exodus.

narrator: April 20, 1945.

As the Soviets tighten their stranglehold on Berlin,

Hitler makes his final public appearance.

The investigative team on the ground has discovered

that the very next day a massive evacuation

of Nazi planes left from Berlin's Tempelhof airport.

A review of the flight records revealed

that one of the flights carried the Fuhrer's

personal belongings.

And that's a whole week

before the Russians take Tempelhof.

The timeline fits,

but the question is, could he have made it to the airport?

Lenny's found a route that goes from Hitler's bunker,

close to the airport.

narrator: The team in Berlin has determined Hitler

could have used subway tunnels

to travel safely underground from the Fuhrerbunker

to within 300 yards of Tempelhof.

The discovery of a walled-off passage under the airport...

That's big enough for somebody to crawl through.

It's a small tunnel, but yes.

narrator: Leads to within 50 yards of the subway.

If the team can prove the two tunnels connect,

it could be a major breakthrough

in the investigation.

There are documented reports that say a tunnel

was built for the purposes of supporting Hitler's escape

and if we could find an additional tunnel,

it's very feasible

that Hitler could have gotten out of Germany.

You still need to close the last 50 yards

of this choke point to find that tunnel.

The best thing to do is to get some ground penetrating radar,

and see if the subway's tunnels align with the tunnel

where he's come to the dead-end.

Let's see what we can find.

Let's get him on it.

narrator: Man hunter Lenny DePaul,

along with expert on the Berlin underground,

Sascha Keil...

narrator: And ground penetrating radar technician,

Joerg Clasen, prepare to scan

in search of this tunnel connection.

Okay, let's see if we can find something.

Work your magic, partner.

narrator: Ground penetrating radar

is a state-of-the-art military technology

that can scan through almost any surface.

It creates images of what lies up to 30 feet

below the ground.

Boom, right about here.

Here's the airport.

Show 'em where the U6 would be, right here?

Yeah.

We were in a tunnel down below, ten feet.

Took us to right here. Stopped.

Ground penetrating radar is the best tool

to find any sort of object in the ground.

This radar is so powerful

it can find something as fine as almost a hair.

We need a tunnel, Joerg.

Okay.

There's something there.

- What are you seeing? - This looks reasonably wide.

Let's see if I can find some other targets

to compare to.

Throw a flag in there,

Just in the middle, yup, yeah.

That's fine.

Assuming that it's going this way,

just move over a little bit.

narrator: The radar has uncovered a void

8 feet underground.

Joerg scans in the direction of the subway system

to see if it continues.

You still picking it up there.

Yup.

Take me right to the U-6.

Perfect.

As he kept going...

Yup, it's still there, same pattern.

He kept getting consistent hits.

Yup, there it is again.

That line was so accurate,

it just kept going and going and going.

That's exactly the direction to the subway station.

We are in the game.

So from the scans, you have a tunnel.

It's roughly about 8 to 10 feet down

and about four feet wide

so it matches exactly what you would expect

from a tunnel.

Better proof you can't really have.

There's the exit from the subway, but if you

remember when we walked off the train, the tunnel,

it runs this way, correct? - Yeah.

So looks like it's a straight shot

into the side of the tunnels somewhere.

They may have done an opening in the side of the tube.

Joerg, here's my question. - Yeah.

Subway probably runs maybe another fifteen feet that way.

- Uh-huh - I'd love to connect

the dots underground.

With a little bit of luck, maybe we can find a hole.

narrator: If this tunnel connects

directly to the subway,

it will prove an underground escape by Hitler

would have been completely feasible.

Phew, all right so we were right about here,

Joerg, I mean anywhere between that sewer top...

- Uh-huh. - And this wall.

Okay.

narrator: Joerg uses a handheld GPR unit

that can detect anomalies as small as fiber optic cables

through solid concrete walls.

How deep can we look, Joerg?

Up to about five feet.

- Five feet beyond this wall? - Mm-hmm.

Oh, man.

Oh! Stop right there, Joerg. What's that?

That's definitely different.

That sure is.

That's a transition of some kind.

Okay let's see if it repeats. - Huh?

Do you hear the sound?

Joerg.

- Yeah? - I think you found something.

That's amazing. There is a deviation

from the normal pattern so there is definitely

something there.

- 100 percent? - 100 percent.

Whew, that's what I want to hear, Joerg.

That's what I want to hear.

To find, there was a direct connection

between Tempelhof Airport to the Fuhrerbunker.

This is so monumental, so huge.

It's very hard to believe.

That's it right there, Sascha.

That could've been the opening to the tunnel.

We just now put the last piece of the puzzle together,

we connected Tempelhof airport to the Fuhrerbunker.

If he wanted to choose this route to get out

of Dodge in a hurry,

ample opportunity, it's a direct shot.

By Joerg, I believe we've got a tunnel here,

takes me right to the airport.

Here's Adolf Hitler that supposedly

took off seventy years ago,

but right now I feel like I'm right behind him.

Hoo, hoo, hoo!Boom!

I love it.

Completely underground,

he could've ended in the middle of Tempelhof.

narrator: With the field team determining that an escape

from Berlin was indeed feasible for Adolf Hitler,

CIA veteran Bob Baer

and war crimes investigator John Cencich

shift their attention to the investigation

where Hitler could have arrived in a U-boat in Argentina,

as reported by the FBI files.

Evidence is piling up the U-boats were coming in here.

narrator: All evidence has been pointing

to a small cove known as Caleta de los Loros.

This place fits the profile

of where you would land a high value target.

narrator: Most German submarines

surrendered after Germany's defeat

46 U-boats went missing and operated in secret.

What we have is on-the-ground reports of U-boats

being sighted there, post World War II.

narrator: The team has uncovered

an Argentine naval document

that reports that an unknown German sub

surfaced near Caleta de los Loros

months after the war was over.

The team also found a fresh water, man-made well.

This makes no sense to be here,

this is unbelievable. Holy crap.

This is a tremendous find.

Hitler, or any other Nazi,

coming into Argentina on a U-boat,

is going to need supplies,

is going to need fresh water,

and then there was also a witness, a woman who,

in 1945, saw this U-boat surface.

She claims that she saw a submarine

once they disembarked the people,

they had nowhere to go back to.

The war was lost.

So it was scuttled.

narrator: During World War II, scuttling,

or the intentional sinking of U-boats

to avoid secrets falling into allied hands,

was a common Nazi practice.

It is estimated that over 200 Nazi U-boats

were scuttled during the war.

If Paesani's eyewitness testimony is true,

and the U-boat she allegedly saw

was carrying out a secret mission,

that boat is now likely on the bottom of the ocean.

I mean, the point is there's a lot of noise

around this location.

In a 70-year-old case,

there aren't a lot of eyewitnesses.

So in order for Caleta to have been credible,

we need to determine whether or not this woman

would have had a field of vision relative to this U-boat.

We need to take this out of the realm of, you know,

hearsay and myth. - Let's rock and roll.

narrator: Nazi hunter Steve Rambam

and US Army Special Forces Tim Kennedy

head to the location of the suspected

scuttled U-boat to verify the eyewitness report.

I'm going to go out into the area

where the sub was sighted. See what's credible.

See whether or not somebody could've seen a sub

from that location.

Tony.

narrator: The team meets Tony Brochado,

the diver on a 1997 Argentinean naval expedition

to locate the suspected scuttled U-boat in this area.

What was the distance

that the woman said she saw the sub at?

And then she sees the submarine

over in the distance.

As an investigator,

eyewitness testimony is not always accurate.

We want to see for ourselves.

We want to visit the scene of the crime, so to speak.

- All right, have fun. - Yeah.

If that looks believable,

we find an indication that in fact subs were landing here,

and it's time to prepare, to look for the sub

that was scuttled.

narrator: Although this eyewitness is no longer alive,

the team will verify her testimony.

Steve's on a boat heading out to the area

that the U-boat was supposed to be in...

and I'm going to go from her vantage point

and see if she's lying.

Okay, this is okay. Aqui es bueno.

The vessel that we're on now is 21 feet, 7 meters long.

That makes us almost exactly one-tenth the size

of the types of U-boats that we know traveled in this area.

If Tim can see us that would tend to confirm

that it was at least feasible.

narrator: After gaining access to the property,

Tim goes to the precise position

where she claimed to have seen the U-boat.

Hey Steve, this is Tim. Do you have me?

Yeah, five by five, you ready?

All right, let's go.

narrator: Because Steve's boat is ten times smaller

than a U-boat, Tim uses the magnification

of a camera lens to level the playing field.

She has a perfect view of this entire bay.

Possible to see something, but nothing.

Tim, how did that look to you?

Oh yeah.

Definitely got you guys now.

You can actually see us?

I still have eyes on you guys.

All right that's pretty conclusive.

You guys are just a 20-foot inflatable,

there's a really good chance we could see a 220-foot boat.

Understood.

I cannot believe I can see this.

It's suddenly feasible

that a sub could've come to this area.

Now it's time to get proof,

we need 2015 tech,

we need to bring in experts,

and frankly, if there's something here,

we are absolutely gonna find it.

If that U-boat was sunk by the Argentinean navy,

or if the Nazis scuttled it, either way,

there should be something there on the bottom of the ocean.

narrator: With the eyewitness report verified,

Bob and John shift their focus to finding the actual sub.

We need to get some real evidence.

Joe Hoyt's our guy.

He's become well known for finding U-boats

that were scuttled or otherwise sunk.

He's the man with the right technology.

Joe Hoyt, he's the best in the world.

He found U-boats off of the coast of North Carolina

that nobody knew were there;

I mean it was surprising

that the Nazis were that close to the U.S. coast.

If that submarine is down there, he's the man that can find it.

Hello Joe? Let me get right to it.

We're looking for a German U-boat off an area

called "Caleta de los Loros."

In 1997 the Argentinean Navy went down there

and they couldn't find anything, which brings us to you.

Yeah, so, the basis of the technology is similar,

but it's really the back end,

the post processing that has gotten a lot better

with the ever-increasing power of computers.

If there's something in the survey area,

if there's a U-boat there, we will definitely find it.

Great.

The problem we're gonna have is we're gonna have

to narrow it down very quickly because the bad weather.

Right, it's about to be winter down there isn't it?

You simply can't be cruising

up and down that shore in storms.

The faster we do it, the better.

Great. Yeah. Sounds great. Um, I'll be in touch.

Great. It's a deal.

If that submarine is down there,

it will be a treasure trove of evidence.

We could be onto the very escape vehicle

that was used by Adolf Hitler.

Let's go find a U-boat.

U.S. Marshal Commandernarrator: Former

Lenny DePaul, and expert on the Berlin underground,

Sascha Keil, have uncovered a secret tunnel connection

that would have allowed Hitler to travel

from his bunker to Tempelhof airport

completely underground.

Believe we've got a tunnel here,

takes me right to the airport.

narrator: With an escape to Tempelhof

during the final days of the war now feasible,

the investigation turns to the heart

of the airport itself.

Knowing what we know now,

that idea of Hitler using the airport

to escape to me is very possible.

Big question is, "What was his plan

once he got to Tempelhof airport?

So they manufacture 'em right here,

they put them together right here and roll them out?

- Yeah. - In and out.

So Hitler would have a lot at his disposal.

narrator: During World War II, the Focke-Wulf Condor 200

was used by the Axis powers for long-range reconnaissance

and bombing runs.

Hitler's custom-built Condor

was equipped with extra large fuel tanks,

armor-plated seats, and an automatic parachute.

Hitler kept those planes here?

Yeah.

If an aircraft decided to take off from here

loaded down with the right people,

you can get out of here in a hurry.

If he did take a Condor out of Berlin,

I can tell you one thing, he's not getting to Argentina.

I mean it's out of range. Too far.

There are no places to stop.

So, uh, you look east, of course he didn't go to Russia,

Red Army is all the way up to Berlin,

it's just impossible.

He didn't go north

into the Scandinavian countries, he didn't go to Britain.

In Africa, got the American army there.

If you look at the political map

with a range of 2,200 miles Spain is the only alternative.

We have FBI document

and it states here, "The United States Army

is spending most of its efforts to locate Hitler in Spain."

I mean, that's extraordinary,

we think that Hitler lived and got to Spain.

It's not we've heard rumors that he's here,

it says they were out and out looking for him.

This is another document,

from the O.S.S., it says,

"Hitler refused to involve Spain in the war

because he has a promise of sanctuary there

when Germany is defeated."

There is one man that Hitler could go to for salvation.

It's Franco.

narrator: Generalissimo Francisco Franco

was a dictator and fascist leader,

who ruled Spain from 1939 until his death in 1975.

Franco seized power in a military coup,

sparking a bloody civil war.

His forces crushed the opposition with help

from bombers and ground troops sent from Hitler's Germany.

without Germany's help.

I mean Hitler, in a sense, created Franco.

In any investigation,

known associates are very important.

We have a dictator who has the money,

and the power to assist somebody like Adolf Hitler

and they also have a debt of gratitude.

Spain's a big country. Where does he go?

Um, Franco had his summer retreat in Galicia.

Yeah, I mean I think his residence,

it's one of the better possibilities.

If Franco had agreed to protect Hitler,

he would want to put him someplace

where he could trust the guards and trust people to be quiet.

Someplace that he knew was out of the public eye.

I think that's the most likely place to look.

Let's see what's up there.

Is it on this road?

narrator: Lenny DePaul and investigative journalist

Gerrard Williams head for Franco's summer palace,

one of the dictator's most secure compounds.

After these houses, we will be able

to see Franco's palace.

narrator: They are joined by translator

and Galicia native Pablo Casasola.

You can see there, on the right hand?

- Okay. - Look at that.

Any known associate of anybody on the run

is very important and critical

when you're trying to find somebody.

We call it "who's who in the zoo?"

Hitler trusts a certain amount of people

that he is going to associate with.

General Franco was one of them here in Spain.

Look at those walls, Gerrard.

What a stunning place, though.

You think we'll be able to get out of this property?

Eh, I really don't know eh.

Well, let's park up and see if we could talk to somebody.

Having a local interpreter and a partner like Pablo

is a huge asset for me.

He speaks the language, he walks the walk,

he talks the talk, so that'll help us immensely.

Hopefully we'll get lucky and get inside.

narrator: Pablo passes the team off as tourists,

gaining them access to the grounds

for a small window of time.

Apparently, we are allowed to come in.

I'm shocked.

Incredible place.

It's a fortress.

Lenny take a look right.

Yeah, oh look at that.

Look at this property.

It's fortified; you got 7-foot stone walls

that surrounds the entire perimeter.

You got houses that I'm sure armed guards were in.

You know you take this route coming in...

Look at this, it's wide open.

It's a perfect spot to land a plane.

It's a fortress, it was well protected

I'm sure there was plenty of eyes and ears around here

when Franco was here.

Any aircraft could have landed anywhere in that area,

but I'm trying to prove that Adolf Hitler was here.

So, I want to get inside this compound

and find some factual evidence that proves it.

Can imagine what's beyond those walls.

Behind those walls, there'll be many, many, many secrets.

There's a story here from May 1945.

Franco's driver allegedly said

a German gardener appeared called Addy Lupus.

Addy is the name that Eva Braun used for Adolf,

and Hitler loved being called Mr. Wolf

and Lupus is Latin for wolf.

So Addy Lupus.

I haven't been able to find a single piece of evidence

that leads me to think that any part

of this story is true,but--

Could be behind those walls.

Let's take a look.

In my career in looking for violent felony fugitives,

I mean I've tracked down plenty of people on rumors.

Even if the entire rumor is not exactly the truth,

there's bits and pieces of what's said in that rumor

that can lead you to a direct hit

on a fugitive that's been running for many years.

There's another entrance right here to the south.

Do they sort of look 40s-ish, or--

- Yeah, yeah. - g Spanish]

What's he saying?

They say we're not allowed to stay here.

We'll tell 'em to shut it off. just give me five minutes,

I just want to look over here.

We have to go.

I don't want to get you in trouble, all right.

Come on, guys! Hey, come on, let's go.

Let's go find a U-boat.

narrator: Tim Kennedy and a team of world-renowned

marine archeologists begin their search

for a scuttled U-boat

that could have transported Adolf Hitler

to southern Argentina as reported in the FBI files.

That a U-boat dropped the most evil person in history

off onto this shore right here

and that's what we're here for.

We're out here to find truth.

Here we go, our boats. - Oh there's the boat.

Is that it?

narrator: Leading the search is Joe Hoyt,

the world's premiere U-boat hunter.

Joe is the chief archeologist for a federal agency.

He's the guy that masterminds searches

across the entire eastern seaboard.

He is, without a doubt,

the peak, the pinnacle, of marine archeology.

Yeah, so we just gotta set the magnetometer station here,

and the side-scan station will be forward,

and I'll kinda go between the two.

To put it to you this way... - Okay

If someone lost a stapler out there,

the package that we put together will find it.

Gotcha.

narrator: Joe's team is armed with the most cutting edge

underwater survey equipment.

This is the brain of the system,

and one of the most advanced side-scans on the market today.

narrator: Regan Lipinski will man the side-scan sonar,

which uses acoustics to creates to-the-millimeter

accurate images of the sea floor.

narrator: Michael Krivor will run the magnetometer,

a highly sensitive magnet that locates trace amounts

of metal buried on the seafloor.

This technology helped maritime archeologist

Robert Ballard locate the wreckage

of the Titanic, some 12,000 feet

below the surface of the north Atlantic.

Again, we're looking for a German U-boat,

it's going to give us a huge magnetic signature,

uh, we have no doubt that the magnetometer

will pick it up even if it's buried.

And if anybody is going to find a U-boat out there,

it's going to be this team.

The water is cold, winter is coming,

and we don't have much time.

Obviously, you guys are ready for it.

Joe we good? - Ready to go.

- Crew good? - Good.

All right, let's rock and roll.

narrator: Two miles off the coast,

the search begins.

So we're like right in the vicinity of where we need to be?

Yeah we're right at the beginning of our search grid,

so we're gonna go a little bit

away from the start point so we can get all

the instruments to settle out and lay out

behind the boat nicely,

make sure everything's working.

We're getting imagery and data. - Yeah.

And the we'll just start going.

narrator: Based on military files,

eyewitness reports,

and the Argentine navy expedition,

the team has narrowed down the location

of this potential sunken U-boat

to a 2-mile search area.

Depending on weather and sea currents,

they should be able to complete their grid search in 10 days.

A little anxious, honestly I'm, like, a little nervous,

like, lets find this [bleep].

- Side-scan's going in first? - Yup.

- We're good to go. - All right, drop it in.

We're ready to put the magnetometer in.

Oh, yep.

So we are going to let this out, 50 feet.

All right, we're there.

- We're up and running and-- - Start line right here?

Yup, start a line.

If I were escaping, this is where I'd come to.

The evidence could be out there.

We have the equipment, we have the guys

to get it done, now we just gotta execute.

So the hunt begins.

narrator: With the newly declassified FBI files

placing Hitler in Spain and the investigation

of Hitler's key Spanish supporter shut down,

Lenny and Gerrard turn to a new approach

to uncover potential Nazi supporters in this area.

If you're looking at a story that's 70 years ago,

most of its participants are dead,

and where do the dead live?

The dead live in graveyards.

So you can go and see if there's a sizeable community,

if there's a German area through the graveyard.

I think it's important to walk the ground,

step in those footsteps. You may find nothing.

There are many times I've found nothing.

There are other times you will come across something

and that something will change

your whole approach to the story.

Two German graves, families,

three or four dead from the civil war, uh--

Okay.

Nothing which establishes a major German community here.

I'm sure the Nazis and the German names

aren't too well-liked around here now, right?

I mean maybe they just bulldozed them over and they buried them.

This is like a whole different section over here.

Yeah, its much more modern now.

- Pablo - Yes.

All these walls are relatively new?

I can see, like, an existing wall

that was pretty much new,

20-30 years old... What is that?

And then behind it was another wall

and it looked pretty old.

You think its possible that I can get a ladder,

and maybe get up and take a look.

Yeah.

Evidence is certainly, uh, scarce

and especially with a case like this that's 70 years old,

so you've gotta look in every corner

of every crevice underneath every rock.

You leave no stones unturned.

Oh look at this, this is all,

this must be an old wall over here.

- You got spaces behind Lenny? - Yeah.

There's a space behind it. - Pablo.

- Yes? - Come on up here.

Take a look at this. - Let me see.

Look on the backside of this stone, see right here?

Can you get down there? - Yeah.

This is a camera GoPro, just set it in front if you can.

Stick that down in there, see if I can see anything at all.

Just drop it down.

Are there words?

What'd they say?

- Gerrard. - Yeah?

- You got a pen and a paper? - Yeah, yeah.

All right hold on.

Lower that down maybe a little bit more.

Um--

H, I--

There's an R.

U, H, E, D, E,

U, T, S, C, H.

Literally it's, "Here lie German soldiers."

It's a bit weird, a bit strange.

Here behind a wall,

in a quite graveyard in a little town in Spain,

it looks like there is actually physical remains

in this cemetery of German soldiers.

- It'd be interesting. - Yeah, very.

Hold on there might be dates or something here,

No way.

Is that a swastika carved on that?

You gotta be kidding me.

You've got the swastika,

and you've got in German, "Here rests German Soldiers."

I mean this whole idea

of a cemetery there tells the whole story.

narrator: Bob and John have uncovered a photo that supports

the field teams' findings of a cemetery with Nazi ties

in Spain, a neutral country during World War II.

I mean could you imagine this in another part of the world?

A country allowed supposed enemy soldiers

to be buried there? I think it's pretty amazing.

The fact that German soldiers, Nazi soldiers,

were buried in Galicia tells us

even though Spain remained neutral,

it was still pro-Nazi.

narrator: Despite confirming Nazi activity, Bob and John

have yet to find direct evidence

Hitler was in Spain.

They turn to a new investigative approach.

If Hitler had escaped from Germany

we need to narrow the focus of where he may have gone.

In the investigative world there is an adage

that the money doesn't lie, people can,

but the money really is going to tell us the truth.

In this case Adolf Hitler had enormous wealth,

so for him to get out of the country

and to be supported, the money had to go somewhere.

The Office of Strategic Services

was following German money and going to

different parts of the world.

narrator: In 1944 the O.S.S., which later became the C.I.A.,

launched a secret project known as "Safe Haven"

to track down the movement of Nazi gold and assets.

In 2009 these records were released

in their entirety to the public.

Let's do an analysis and see where the money takes us.

Okay.

narrator: Using state-of-the-art software,

the team analyzes the data from project "Safe Haven"

to uncover patterns in the movement

of these Nazi funds.

Wow look at that.

Spain is really lit up, but look at Galicia,

this is like really bright hot.

What is that?

Let's go a little closer here.

Vigo, Spain?

294 thousand.

Largest export: Tungsten.

What's the importance of Tungsten?

It's a--it's a substance that's used to make metal,

to make weapons of war.

So it's actually crucial for the Nazi war machine.

- Absolutely. - Now, can we take a look

and see what sort of money's involved here

in the tungsten in Vigo, Spain?

1945 total: 22.7 million

or 299 million.

It's a third of a billion dollars.

That's a lot of money.

During these years,

the Nazis are spending this amount of money.

They certainly have people on the ground

helping to facilitate this entire operation

and hence provide this infrastructure for Nazis.

This infrastructure would have been unaffected

by the defeated Germany.

This becomes absolutely crucial area in terms of

moving money, people, supplies and the rest of it.

When you're doing something like moving a fugitive,

you can only go to trusted networks.

Hitler's going to take a place like Vigo

with so much money very seriously.

We can finally narrow Spain down

to one likely transit route for Adolf Hitler.

Let's get Lenny on the ground

and see what we have there. - Let's do it.

narrator: Lenny and Gerrard arrive in the small town

of Vigo, which sits on a 14-mile bay

leading to the Atlantic ocean.

narrator: Joining the team is Eduardo Rolland,

an historian and expert on the German presence

in Galicia, Spain.

So that's to make tungsten steel?

To make the hard steel, yeah?

Enormous?

So if there were U-boats activities here,

it was in the early part of the war?

'39 to '42?

So in 1945, German soldiers were here in U-boats?

That's, that's-- I mean that really is shocking.

What amazes me, I mean...

we have submarines in a Spanish port in late '45.

These are all meant to have surrendered

It's shocking, Eduardo.

U-boats were refueling and replenishing here

after the war.

That's interesting because Nazi Germany

is defeated militarily,

so there's no obvious reason

why submarines would be coming here.

They had to be on a mission, they had to be doing something.

It's very likely they were carrying out some sort

of clandestine operation.

Were people using this port to escape?

Were the Nazi criminals using Vigo to escape from Europe?

The money trail's brought us to the port of Vigo,

trying to figure out where Hitler could have gone,

but what I got was bigger.

I got an exit for Hitler.

There were U-boats popping up all over the place

and if Hitler got on a U-boat right here in Vigo

and made it to the Atlantic ocean,

he was home free.

What a perfect opportunity and a perfect spot

for him right here.

narrator: Off the coast of southern Argentina...

- Anything Mike? - Negative.

I've got nothing but flatline data.

narrator: Tim Kennedy and a team

of elite marine archeologists

are in search of a sunken German U-boat

that could have transported Adolf Hitler to South America,

as reported by the FBI.

We're almost at the end of the line right now?

About ten seconds away.

narrator: But after 3 days,

the team has come up empty handed.

- End of line. - It's end of line right there?

Yeah, we can go ahead and shut it down.

- All right. - End of line!

Ah, there we go.

To find a submarine in the ocean,

it's not just something that just happens.

You know, it takes time, it takes work,

it takes repetitions, just going back and fourth.

We're out there, it's a waiting game,

we're just patiently looking for one thing,

It's just like, you know, being a sniper.

You have to be ready at any moment

for something to cross that scope.

We're getting towards the end of the day anyways,

so I think we wrap it up now and re-group tomorrow,

hopefully, if the weather holds out for us.

narrator: With the seas picking up,

and temperature dropping fast,

the team is forced to pack up their gear

and head back to port for the day.

This is by far the coldest it's been out here,

tomorrow they're saying that the wind's gonna be way up.

We don't have a lot more time.

the conditions are becoming less and less favorable

for us to really be efficient in searching.

We have covered so much area in our search.

It's been completely barren.

I really want to find this boat.

The evidence is there, that it could be out there.

It's always a drag to not find anything

Yeah.

Stop it here?

narrator: The boat's fishing sonar picks up

an abnormal signal from the seafloor.

That's a pretty hard target. It could be wrong,

it could be fish, it could be a very dense

school of fish, but it's a hard target.

Sebastian, can you loop back and go back over that spot?

Okay.

narrator: The team circles back to the location

where the fish finder pinged to scan

with their more sophisticated technology.

Let's see what this target's got.

We're going to 3D scan it

from a side-scan, see if we can see anything.

How far to target?

One minute, 363 feet.

Let's find something.

How far to target?

52 feet. Six.

Oh big pod, we got a pod.

- Five, four, three-- - It's going up, up, up.

Two, one.

We got something, fellas. What do you got on the screen?

Anything on the side-scan? What'd you get?

Oh there we go, we got something manmade.

For sure, yeah, right there.

That's a--it's a solid straight line with a--

with at least one right angle in it.

That could be a U-boat.

Having the real possibility

that this is a U-boat off the coast of Argentina,

and we're going to be the first people

to be on it is-- is unreal.

That's a good-sized target.

I think we've got something for you guys to dive on.

- Yeah! - Whoo.

We gotta get in the water and see what this is.

- I'm a little excited. - See what's there.

- Ready to go, man. - Absolutely incredible.

narrator: Next on "Hunting Hitler"...

Wow, what a perfect escape route.

Hitler was here?

The things that we've seen in Spain...

Is he telling me there was an enigma machine

at his grandfather's place?

Have just been mind-blowing.

The Nazis build underground like cathedrals above ground.

They were planning on something huge.

There is a chance that there's a U-boat right here.

Three, two, one!

It could completely change history.

It looks like I can see something.

Here we go.

It looks like some steel of some kind.
