Original subtitles

Where we are in Argentina, on this shore,

I can look across and see Paraguay.

Want to go to Brazil?

I just go a little bit up this river right here,

I'm in Brazil.

It's perfect.

I'm looking for one thing:

places where Nazis can go hide, one in particular.

Here we are in northern Argentina,

and we have found just that,

the perfect hiding spot for a Nazi on the run.

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.

narrator: Previously on "Hunting Hitler"...

Argentina, it's exploding.

Hitler "is living in a great underground establishment."

Charata's our place.

Did they fly the swastika flag?

Find me a bunker?

It's definitely an area of interest down here.

Holy moly. Look at this.

It may have been that Hitler was in Charata

and then got up and moved several months later.

"The Nazis in Misiones are reported to control

a system of roadways known only to them."

We need Tim Kennedy there on the ground.

We've got to do it now.

narrator: 600 miles north of Buenos Aires,

in the remote region of Misiones, Argentina,

Tim Kennedy, U.S. Army Special Forces,

heads into the dense jungle to follow a lead

in a declassified FBI file that could place Hitler

living in this area at one point.

I'm in a 4x4 truck,

and it takes forever to get out here.

As an archaeologist, whenever I look at a new site,

I try and stay very neutral about it,

don't get too excited, so I don't bias my judgment.

narrator: Bob has arranged for Philip Kiernan,

expert on German archaeology, to join Tim

in the investigation.

This site in particular is--

it seems very problematic not to get emotionally involved

to it because there's so much mystery.

You know, there's so many unknowns.

narrator: For decades, only legends and local folklore

have provided an explanation for three mysterious

stone structures isolated from society

and inaccessible by roads.

But recently, a team of archaeologists

began unearthing artifacts that suggest

that this site served a sinister purpose.

To provide a safe haven for Nazis on the run.

This would've been way out of town.

narrator: After driving through the night,

Tim and Philip reach base camp.

Hello. Daniel?

narrator: Daniel Schavelzon, the director of the dig,

is responsible for dating this complex to the 1940s.

Tim and his crew will be the first outsiders

to investigate this site.

What we are trying to do

is to understand who was living there,

what the purpose of the buildings,

when the building was in use.

A lot of these cans seem to be same size.

I don't know if these are sardines or what.

Sardines, corned beef, milk.

From my perspective, when you have a hideout,

it's pre-positioned and planned,

and you would find stuff like this that's sitting there,

that's ready to be used. - Yeah.

This was all canned food, canned meats.

Whoever lived here could've lived off that food

for a long period of time.

narrator: Daniel shows the team the newest discovery

pulled from the site just days earlier.

This is a box made 1940.

It's engraved, and we found inside the wall.

We was lucky to find it.

Inside, there are several things.

Here we have the coins.

This is very interesting.

There we go.

That's a swastika.

There you are, a Nazi coin

from the period of the Third Reich.

Oh, my God.

To see a Nazi coin takes your breath away.

The swastika, even now, is so powerful,

and finding this coin

is an indication

that Nazis were living here.

We have a kid wearing a Nazi uniform

with a swastika on his arm.

It's an incredible picture.

If you see the other things,

that's the picture.

Oh.

Yeah...

They just have Hitler and Mussolini,

taking a stroll.

Without a doubt, this is forensic evidence

that there were Nazis here.

After seeing that, I want to get on that property so bad.

I want to understand what was going on there.

narrator: At first light, Tim, Philip, and Daniel

hike deep into the jungle to investigate the complex.

I'm coming to this site with a bunch of questions.

I want to know who built this complex.

Why did they build this complex?

If I get these questions answered,

I can discern if it was possible

a high-level Nazi could've come here.

Here you have building one.

It's an impressive construction

in the middle of the jungle...

made by stones.

That's the door, and you have a veranda.

What's the purpose of a veranda in the middle of the jungle?

This is very cosmopolitan.

This the kind of entrance you might see to a house in Europe.

For sure it's not made by a local architect.

This is majorly labor-intensive to build this.

The choice of material indicates that,

so if you wanted to build something quick and cheap,

you would use wood or bricks,

but here they've actually quarried stone.

It's a lot more work than shipping bricks here.

Oh, absolutely, but if you buy a great amount of bricks,

at the city, everyone know it.

- Yeah. - But two or three, four people

working in the middle of the jungle, nobody knows.

We have two bedrooms, a kitchen, a restroom,

and the remains of the original floor,

blue and yellow tiles.

See the yellow?

And the blue.

This is too much floor for a jungle house.

- Whoa. - It's a real modern restroom.

That's the place for the toilet side.

That's the reservoir for the tank.

For the tank.

And here you have the-- for toilet paper.

It's too much work.

This is ornate.

Did you go in this?

Wow, look at that.

- The tiles are glass tiles. - This is weird.

It is a two-bedroom,

one-bath house

in the middle of the freaking jungle.

narrator: Adolf Hitler was known for his opulence.

A declassified U.S. military file from 1943 reports

that at the height of the war,

Hitler had a special plane bringing him asparagus

and bonbons fresh daily from Paris,

and he set up ten intricately built headquarters

throughout Europe,

with his private Berghof residence in Bavaria

adorned with rare marble and wood walls

and priceless antique furniture.

We know there were Nazis here,

and this house was built for somebody

that has a very high standard of living.

Obviously, Hitler is the figurehead

to the entire Nazi movement,

so if that man's on the run,

it's gonna be a place like this that he would run to.

We are on to something.

This Compound Misiones is turning out

to be something important.

narrator: CIA veteran Bob Baer

and war crimes investigator John Cencich

review the on-the-ground findings

from the jungles of Misiones,

where a declassified FBI document led the team

to a mysterious Nazi complex in the north of Argentina.

Who builds a tiled bathroom

in the middle of the jungle?

If we were talking about the 1970s

and the 1980s, we're gonna be looking

at some drug dealers,

but here, back in the 1940s, it doesn't fit.

What kind of Nazi withdraws deep into the jungle,

into a fortified compound,

and this opulence, except somebody very important?

Misiones is extremely interesting

because if you're protecting Adolf Hitler,

he's not gonna show up and stay at the local hotel.

And to find a facility in the Argentine jungle

tied to Nazi Germany is huge.

It gives a lot of validity to the FBI reports.

narrator: With evidence from Misiones

now providing corroboration on the FBI files,

the team considers opening a new front

in their investigation.

We need parallel inquiries.

We need Tim Kennedy to continue

digging in South America,

but the other part of this equation

is what happened in the fuehrer bunker

in Berlin leading up to April 30th, 1945?

I totally agree with you.

We simply go back and reexamine Berlin,

and that's what really interests me.

Could he have faked his death or not?

There's two sources of evidence

that we want to take a look at.

narrator: Two main sources have been used

throughout history to determine that Hitler

committed suicide in his bunker.

Source one: Testimonies from members

of the Nazi inner circle

all claim that Hitler and Eva Braun

took poison, and then Hitler shot himself

before their bodies were wrapped in blankets,

carried out of the bunker, and burned.

Source two: Official reports

from the Soviet troops who stormed Hitler's bunker

and controlled the crime scene,

along with all forensic evidence.

I want to get Lenny DePaul on the ground in Berlin

to look at both sources.

Former U.S. Marshal, he's done this,

manhunts, and if he can establish

that he did die in the bunker, this investigation's over,

of course. - Right.

narrator: Lenny DePaul, one of the most skilled

man hunters in the world, makes his way

through a Nazi bunker built in 1942.

I was the commander

of over 380 full-time investigators.

We were mandated by the United States Congress

to go after the most violent felony fugitives

around the world.

If somebody's on the run,

we're the ones that's chasing them.

The first step in any investigation

where somebody has allegedly killed themselves,

is to find out if, in fact, they did do that.

And I've had fugitives drive cars off of bridges

not even being in them.

If you can prove to me that Hitler committed suicide

on that day, then I pack up and go home.

If not, I continue this investigation.

narrator: Lenny will start his investigation

with the first source used to confirm Hitler's suicide,

the eyewitness accounts.

- Sascha. - Yo.

narrator: But seven decades later,

all of these witnesses are dead,

so Lenny has reached out to Sascha Keil,

chairman of Berlin Underworld,

an organization that has preserved

the little-seen archives from the Third Reich.

What I'm looking for is eyewitnesses,

uh, anybody in his inner circle

that could positively ID the body of Hitler.

Okay.

Mm-hmm.

narrator: After the Nuremberg Trials,

Michael Musmanno, one of the presiding judges,

conduced interviews with over 200 members

of Hitler's inner circle, many who claimed to be

witnesses to his final days.

The most important question was always,

"Is Hitler still alive and could he escape?"

Wow.

And it's all collected in this database.

narrator: Sascha is the first person

to compile these hundreds of hours of testimonies

into a searchable database.

What words do you need?

Uh, let's search for, uh...

"body,"

"dead," "identity."

- Searching. - Look at that.

I see we got some hits, okay. - Looks good.

Hmm.

"Did Linge say he was actually present

when Hitler took the poison? No."

Who's Linge?

Linge was his personal butler of Hitler,

and he was during the whole wartime.

He was the first person he saw at the morning.

He's an important guy.

One of the most important eyewitnesses.

So Linge can't say

that he was present when Hitler took the poison.

I don't buy it.

Can I see the next one?

Yeah.

Who's Jackubeck?

This was one of his SS guards.

"Linge carried Hitler's body upstairs and outside,

and Kempka carried the body of Eva Braun.

She was wrapped up too.

That is why Kempka could not tell

whether he really had seen that Hitler was dead

because he had not seen the body."

All right, so basically, what Jackubeck is saying is,

he's getting it as a third-party person.

It's hearsay.Wow.

Can I see the next one?

Here we go again.

"Gestapo member Erich Mansfeld,

he could recognize the body as being that of a man

but could not be certain it was Hitler."

He couldn't even tell himself,

'cause he hadn't seen the body.

That's his testimony.

No one did.

You know what, Sascha, nobody's really identifying

either one of them, because they can't see them.

They're wrapped up in blankets.

Nobody sees his face and said, "That's him."

- Yeah. - Unless it wasn't Hitler.

It's easy to say he is, but no one can prove.

That's my whole point.

No one can prove it. There's no evidence.

There's nothing that points

to either Eva Braun or Adolf Hitler.

That's the problem.

If it wasn't Hitler

or Eva Braun,

who do you think this body was?

Well, in a dictatorship,

it's a common instrument to have doubles.

You had guys like Osama Bin Laden,

- Osama Bin Laden... - I think he had ten

different body doubles, so it very well could be

that the body that was wrapped up

in that blanket was not him.

No one could positively identify Adolf Hitler

as the person being rolled up in that carpet

and being taken away by the Russians, nobody.

So, at this point, it's an open case.

Lenny's found reports

from these eyewitnesses, but nothing firsthand.

narrator: Bob Baer and John Cencich

review the findings from both legs

of their investigation,

a Nazi complex in Misiones, Argentina,

and eyewitness testimony in Berlin

that was used to certify Adolf Hitler's death.

There's nobody that actually looked at the body and said,

"Yeah, that's the Adolf Hitler I know."

There's no firsthand evidence.

I mean, you're a criminal investigator.

Have you ever been in a situation where someone said,

"I didn't pull the blanket back, and I don't know

if that was that really him?" I mean, or the police--

No, it's odd.

Something is afoul.

I totally agree, and number two,

we got to get Tim to continue to dig

at Misiones, look into this compound.

A lot of money, a lot of resources,

a lot of time put into this,

and the fact that there are Nazi artifacts there,

what kind of Nazi

withdraws deep into the jungle,

into a fortified compound,

and this opulence, except somebody very important?

If you look at Eichmann, senior Nazi leaders

that did make it to Argentina,

these people had to work for a living.

They didn't live in something like this.

narrator: Thousands of Nazi war criminals

found refuge in Argentina, including Adolf Eichmann,

one of the masterminds of the Holocaust.

Eichmann lived in a small house

under the name Ricardo Klement, eventually becoming a mechanic

at the Mercedes-Benz factory in Buenos Aires.

If Nazis in Argentina could live in the open,

whoever this was was somebody that couldn't live in the open.

Some Nazi with a lot of money was scared of something,

and it wasn't somebody that Argentina

would feel comfortable about giving political exile.

This held somebody very special,

and the question is who.

narrator: In the dense jungles

of Misiones...

Let's go to the other building.

narrator: Tim Kennedy and German archaeology expert

Philip Kiernan continue their investigation

of the three-building Nazi complex.

After discovering that building number one

was an opulent residence,

head archaeologist Daniel Schavelzon

leads them to the second structure,

the purpose of which, even after weeks

of close examination, remains a mystery.

This is what we call building two.

The same kind of architecture,

the same kind of work on the stones,

but we don't have

an explanation for this building.

As the other one, it was a house.

The layout doesn't make any sense.

It had to serve some functional purpose,

but we can't discern what that is.

My first impression of building two

is that it feels like a vault.

It's gigantic, thick walls,

but there's a hole

that's six, eight inches off the ground.

It doesn't make any sense to me.

Right now we have a lot more questions than we have answers.

We're definitely dealing with a structure

where a huge amount of effort has been made to create it.

Imagine carrying all of those stones

from their source, wherever that was.

That's a heck of a lot of work

here in the middle of the jungle.

Do you mind if we look around a little bit?

Oh, yes, of course.

Yeah, awesome. Thanks.

narrator: While Philip remains

at building number two in hopes of determining

the purpose of this mysterious structure,

Tim heads deeper into the jungle

to investigate the third and final building

further up the mountainside.

If we have Hitler hiding in this house,

you're gonna have security measures.

Building three, it's high up on the mountain.

It looks down onto the area

of where building one and building two are.

My first assumption is that it's an observation post.

Oh, wow.

But once I was there and trying to find

a vantage point where you could see,

it's difficult.

Your visibility's limited

by the vegetation around you,

so it wouldn't make sense.

If I was gonna set up an observation post,

you know, I'd do it up there.

I went out looking for an observation post.

What I came across, really, what I stumbled on,

was far more important.

One of the questions that we had coming into the site--

these are gigantic buildings with a ton of stone.

Where did they get the stone from,

and how did they get it to the site?

Looks like chisel marks.

This has to be the rock quarry.

Cut there, cut there, chisel here,

you got your stone.

When you see a chisel mark

at a right angle to a horizontal line,

it brings your attention to it.

They took a chunk of stone off

right here and right here.

We'll find a whole bunch more chisel tool marks

just like this and this and this and that and this.

Oh, man, look at this.

I stepped right on top of it.

We have a perfect rectangle.

The big question is, how do you transport them?

How do you get them from here to your building site?

They didn't get them out the way I came in.

Oh, wow.

How did they do it without anybody knowing?

They were right here.

You roll them downhill, have a boat

transport them around the river

right to your building site.

This could've been completely built in secret.

It's a horrible thought,

but if you're gonna tie up loose ends,

the workers have to go too.

Hell, Saddam did it.

He'd build a palace, have a safe room,

and the contractors that built it,

they just disappeared.

We're in the middle of the jungle.

It's not hard to hide a body here.

narrator: Deep in the Argentine jungle,

the team follows a declassified FBI report

that could place Hitler at a suspected Nazi refuge

months after he was believed dead.

While Tim Kennedy searches a quarry to determine

how the site could've been constructed in secret,

Philip Kiernan joins a team of archaeologists

investigating building number two.

The purpose of the mysterious structure

has baffled experts for years.

Based on the finds that Daniel tells me

he's recovered in house number two,

fragments of iron, fragments of iron tools,

it seems much more likely that we're dealing here

with a workshop than a domestic structure.

narrator: After days of working the site,

the team makes a significant find.

Wow.

Wow, it goes at least eight, nine feet back.

It's clear there's a tunnel underneath the house,

and it occurred to me it must be some kind of drainage feature,

a feature for moving water.

The water input seems to be here.

It entered the building through this hole,

and it looks like the water's almost flowing into there.

So if this theory's right,

the water's flowing in here

and then into this hole,

and then it should be coming out down there.

As I thought about it more and more,

it occurred to me that this tunnel was leading water

from a higher point behind the house,

through the house, and out.

What purpose could that be for?

I think we're looking at a mill,

something that uses the power of water

to turn a wheel to generate electricity.

The big question, of course,

is, "Where did that water come from?"

The next thing to do is to go up the hill

to see where in a straight line,

that might be coming from.

narrator: Philip's climb leads him

to building three, near the peak of the mountain.

That's the real beginning.

That looks very convincing.

It might be that there was a metal tank in this room

that filled up with water, and the mechanical force

of gravity is being used to speed up water

to reach the mill down below.

narrator: Philip believes rain would collect

in building three, and flow through a series of tunnels

downhill to building number two,

where the water would turn a large mill wheel,

creating a reliable source of electricity

completely off the grid.

This isn't the kind of technology

that one would expect to find

out in the middle of the jungle.

This site is producing

a heck of a lot of finds.

You know, if they had power and batteries,

those are big checks

regarding the feasibility

of this being a real hideout location

for somebody on the run.

Looking at this compound,

they had everything that they needed

to be completely self-sufficient.

They had canned food.

They sourced their materials from right here,

so that they didn't have to buy them.

It has running water, so they might have electricity.

It is pristinely designed to hide a high-value target.

narrator: On their last night in Misiones,

Daniel shows the team the latest stash of objects

his archaeologists just unearthed from the site.

Adolf Hitler suffered from

severe, chronic stomach cramps

and digestive problems.

In 1943, a secret U.S. military document

reported that Hitler was "in fairly good health

except for his stomach ailment,"

and a diary of Hitler's physician reported

that by December 1945, his abdominal pain

was the strongest affliction "of his whole life."

I can't even believe I'm seeing this.

Hitler has a serious ailment,

and stockpiles of medicine for that type of problem

are found in this building in Misiones.

It's something that you certainly

can't cast your eye away from.

For me, it's a huge breakthrough.

We are just simply looking at the possibility.

If the Nazis had moved him from Germany,

could they have hidden him in Argentina,

and taken care of his health problems and his security?

And the Misiones compound says yes.

In Misiones, we've got Nazi artifacts,

a fugitive's lair of somebody of extreme importance,

and now we've got stomach medicine

which matches the type of medicine

that Adolf Hitler took.

My imagination runs to figure out

who else could this be,

other than somebody very important

on the level of Adolf Hitler.

We do not have an independent,

reliable, objective view

of Hitler's last days.

There's so many witness statements that were given.

Not one says that they saw Adolf Hitler kill himself.

What they saw was a body come out of the bunker,

presumably Hitler's, but it's in a blanket.

They take it out in the garden,

throw gasoline on it, and burn it.

Then the Russians come and they see bodies.

And one's in a blanket,

and somebody says, "That must be Hitler."

But how do they even know it's Hitler?

I mean, they don't know. - They don't.

You don't collect forensics

in the middle of a war.

You don't hold up your hand and say, "Oh, excuse me,

"I'd like to get the DNA off this corpse

because I don't know where he's from."

It doesn't happen that way.

I want to see

some scientific evidence,

just a piece of forensics

that would suggest he really died here.

narrator: Bob shifts the investigation

to the second source used to confirm Hitler's suicide,

the forensic reports from the Soviet troops

who collected Hitler's supposed remains.

There's the potential for that.

There's the skull that remained

in Russian control.

narrator: The Soviets kept the skull

they allege to be Hitler's

under lock and key until 2009,

when the first and only American scientist,

Dr. Nicholas Bellantoni, was granted access.

He took samples back to his lab and using DNA analysis,

determined the skull belonged to a woman in her 30s.

It could've been Eva Braun's.

We don't know. It's female, right age,

but if we could prove that was her DNA,

we are now in a position to say,

"We don't have a clue what happened to Hitler."

Okay, so let's call Nick.

We need forensic science to help

make this picture clearer,

and he's our only hope.

So, you went to Russia, huh?

We did have an opportunity to examine

the cranial wall fragment that they believed was Adolf Hitler,

but the cranium was actually housed in a rolodex container,

and it had been jostled by movement,

and it was charred.

You could see black scorching around the edges,

and it had an exit bullet wound

coming out the back of the head.

There was an exit wound?

It was clearly an exit wound, absolutely.

You think it was Eva Braun's skull?

You know, Eva Braun

clearly fits the profile.

The only contradiction would be the interrogations

of the Germans that were in the bunker

who don't refer to her being shot

but do refer to Adolf Hitler as being shot.

Now, if we had a sample

from a living relative of Eva Braun, would we

come closer to identifying whether or not the skull

was indeed Eva Braun's? - Yeah.

Wouldn't that be exciting to be able to

try to match that up?

And if new samples were available,

that would just be great.

If the DNA from that skull

turns out to be Eva Braun's,

and in fact, she died of a bullet wound,

everything we've been told

about the final days in the bunker

is thrown into doubt.

We have to, first of all,

demonstrate just how bad the evidence is.

If it is her skull,

and there was only one shot coming from the bunker,

we know that shot didn't kill Hitler.

And the plot really thickens because that suggests strongly

that Hitler was complicit in her death,

and then she dies on the scene,

and he flees.

I think that's huge. It's huge.

So we are way far from certifying his death.

narrator: In a small suburb in southwest Germany,

Lenny DePaul and German private investigator

Stephan Schlentrich are on the hunt for forensic evidence.

We have a very good chance

to get good DNA if we need it.

That's extremely important.

narrator: They head to the home of the only known

living relative of Eva Braun.

My suggestion is that we do

a very smooth approach, and maybe I go alone.

We need to see if we can get some DNA

from Eva Braun's only living relative

and try to prove that the skeleton remains

that were found by the Russians

were, in fact, Eva Braun's.

If she consents,

we should be able to break this case wide open.

I think we got one shot at this.

You go up by yourself.

- Yes. - You know, work you magic.

I'm really thinking about how far I can go

and how she will react.

You know, everything can happen.

So, Buddy, I leave you here, huh?

Yeah, go work your magic, man.

Come back with some good news, will you?

Okay.

Any luck?

Bad news.

She refused to give me any information.

Oh, no.

It was very clear for me

after a couple of minutes that the family

would really like to end with all that,

not to talk about their history,

not to talk about the relationship to Eva Braun.

I was not so happy with it,

but I think we have to respect that.

She's the only living relative?

Yes, absolutely the only one.

That's the only shot we had.

So the forensics window is shut,

is that what you're telling me? - Yeah.

No more living relatives?

For here and for Germany, yes, unfortunately.

It's too bad that Stephan was not successful

in drawing any DNA, but he did it right.

He respected her thoughts and her family's decision,

and we're moving on.

Well, we're gonna have to go down another road.

We got to figure something out.

So it's a wash on the DNA.

We're just not getting any DNA.

We're missing all sorts of evidence

that he died there.

We have no forensics,

no eyewitnesses.

Based upon this lack of evidence,

it's certainly a strong possibility

that some aspects of suicides that occurred

in the fuehrer bunker were staged.

It is possible that he faked his death.

The question now is, how did he get out

without anybody noticing

and certainly getting around Russian lines?

Berlin at this point, is under artillery fire.

This late in April 1945,

this is a city under siege.

Been in a lot of firefights and around a lot of war.

It would've been very difficult

for Adolf Hitler to get out of Berlin.

The problem, of course,

is we don't have the crime scene.

narrator: In 1999, Hitler's fuehrer bunker

was filled in and paved over to make way for a parking lot,

destroying critical evidence of Hitler's possible escape.

In any criminal investigation,

it's always best to go back to the scene of the crime.

In this case, we can't do it,

but we have access to the next best thing.

That's the forensic reconstruction

of the fuehrer bunker.

narrator: Forensic historian

and 3-D artist Christoph Neubauer

has spent a decade scouring historical evidence

to create the world's most accurate simulation

of Hitler's bunker.

It's based upon looking at documents,

interviewing eyewitnesses, all of this put together,

synthesized, distilled, made into 3-D images.

It's allowed us to peer in

to the bowels of the fuehrer bunker.

You never want a bunker to become a prison.

You always want to have an escape route.

The escape route clearly

couldn't be across Berlin in a car.

It just--you can't make it.

Even in a tank, you couldn't make it

at that point. So what you want to do

is, like any sort of rodent,

you want to go underground and appear someplace else.

There's a massive web of tunnels

that are underneath Berlin that go in all different directions.

There's four exits to the fuehrer bunker.

What intrigues me the most are exits number two and four.

They both make their way to underground tunnels.

What we need to do now, really, is to

get Lenny DePaul over there.

Let's see--is there a way for him to get out of Berlin

via this massive web of tunnels?

Yep, I like it.

This is it? Right here?

That's the entrance.

- Wow. - Yeah.

Please help me here.

narrator: To give Lenny a sense of

the massive scale of the tunnel system

built under Hitler's regime,

Sascha accesses a rarely-seen section

of Berlin's underground.

Boy, this is really tucked away and nowhere.

So this isn't open to the public?

Nobody goes down here?

Nobody knows,

so they cannot go down here.

- Wow. - The neighbors don't know.

It's a hidden place.

Let's go, man. This is exciting.

To take a look at what the possible resources

that Adolf Hitler could've had

gives me a great idea as a fugitive investigator,

in what was at his disposal and how he could've used them.

Yes.

- You okay? - Yeah.

Wow.

Whew, that's quite a drop.

Wow, look at this.

Look at that.

How many of these tunnels exist under Berlin?

When was this tunnel built or tunnels like this?

Wow.

narrator: Under Nazi rule,

Berlin's underground was expanded

into a sprawling web of 93 miles

of interconnected tunnels and bunkers.

This multi-storied underground

had independent power, heating, and ventilation.

Hitler and Albert Speer built this city beneath a city

to move hundreds of thousands of people

efficiently throughout Berlin,

but once the war was lost, these tunnels provided Nazis

with safe shelter and a means of escape.

Look how dark it is. Shut your light off.

Yeah, these tunnels go for miles.

So they had no idea that the underground world

existed in Berlin.

Wow.

Boy, what a perfect escape route.

In a subterranean environment like this,

not knowing the lay of the land,

it would be hell trying to find somebody.

You could get lost for days, probably weeks down here.

So you're up against it.

It's dark, you don't know where you're going,

and the people you're looking for

are armed and extremely dangerous.

What a perfect place for Hitler and Eva Braun to escape in.

Yeah, it makes no sense.

Knowing the Russians were not gonna come down there,

why would he kill himself?

So, was he able to escape and get out of Berlin?

We're gonna find out.

narrator: Next time on "Hunting Hitler"...

A German submarine?

That's the way I'd get there.

Underwater, there's no way to detect these things.

Where there's smoke, there's fire.

Three crewmembers

clearly saw a submarine emerge and submerge.

What happened to the sub?

They don't know.

We need to find out where this leads.

Look at this.

Adolf Hitler, his mindset was escape, escape, escape.

He's gonna do whatever it takes.

Do you think Adolf Hitler was on one of these submarines?

- As if a king had arrived. - As if a king.

Oh, man, I've got something right here.

Holy [bleep].

Hey, whoa, whoa, whoa, whoa, whoa, whoa.
