All language subtitles for Lost Gold of World War S01 E01_track3_[eng]

[dramatic music]

‐ For 70 years,
legends have been told

of a buried treasure,

shrouded in danger.

One of the great mysteries
of World War II.

‐ Something very
secretive and strange

has gotta be buried
in that mountain.

‐ A covert operation,

led by the notorious
General Tomoyuki Yamashita.

‐ Whether it's gold,
weapons,

military secrets...

whatever Yamashita hid

would be hunted
for decades to come

by treasure hunters.

‐ A tale that has
intrigued world leaders...

‐ Rumor has it that

MacArthur knew
about the treasure.

Truman knew
about the treasure.

Churchill knew
about the treasure.

‐ And even the CIA.

‐ How was the U. S.
government involved?

‐ Now a team of Americans
is on the hunt

for this lost chapter
in World War II history...

‐ We have a secret weapon.

We have an eyewitness.

‐ With the help
of a local farmer...

‐ Hello.

‐ I've traveled
a long way to meet you.

‐ His story...

May be the key
to finally unlocking

this lost chapter
in World War II history.

‐ There's something
right here in this area.

‐ The question
we have right now is,

what is the best way
to get inside this mountain?

‐ The Japanese didn't want you
to find their treasure.

We're not gonna give up.

Peter:
For the past 15 years,

John and I
have worked together.

John: When I was about
8 or 10 years old, my grandpa

used to tell me stories
from World War II

about Yamashita's treasure,

and I...
I caught the bug.

As far as Pete and I
are concerned,

we both share the same mindset
of solving mysteries.

Solving this mystery,
you know,

is definitely gonna be

one of the pinnacle
achievements of our career.

It'll change how people
think about World War II.

‐ During the Second World War,

Japan conquered vast areas
of the Pacific

looting gold,
ancient artifacts

and other riches.

‐ The Japanese were
looting all of China

and Southeast Asia,
Thailand, Taiwan, Burma.

They were just taking everything
that was not nailed down,

anything of value.

‐ By 1945,
the Japanese knew

that they were
gonna lose the war.

‐ As the U. S. forces
blocked the way to Japan,

General Yamashita,

commander
of the 14th Area Army,

allegedly buried that treasure
here in the Philippines

using prisoners of war,

many of them Americans.

‐ Once everything is buried,

Yamashita, he surrenders.

‐ The commission finds
you guilty as charged

and sentences you
to death by hanging.

‐ When the war ended,

he was tried
and quickly executed,

taking his secret
to the grave.

‐ This mystery hasn't been
solved for 70 years.

And we've been given
a chance to solve it.

‐ Now, drawing on decades

of experience
and historical recovery

and excavation,

partners Peter Struzzieri
and John Casey

arrive at a remote mountain
in the northern Philippines

where General Yamashita
made his last stand.

‐ Look at how
rugged that place is.

‐ Their mission?

Find what he buried
here decades ago.

‐ I have been treasure hunting
for about 50 years.

As far back
as I can remember,

even as a kid,

I dreamt
of Yamashita's treasure.

I've become obsessed.

‐ Passionate.
‐ I like "obsessed" better.

‐ Okay.

‐ It's rumored that
175 treasure sites

are scattered
across the Philippines.

Peter and John believe
this mountain

may be one
of the most significant.

‐ I've done a lot of research
on this mountain.

But I had to come here
and see for myself.

Something was going on here.

‐ Strange symbols
are carved into rocks

all over the mountain.

Some experts believe
these a part of a unique code,

one studied for decades

and allegedly used
by a secret society

of Japanese royalty

called "The Golden Lily."

The code was designed
so only they

could recover the treasure
after the war.

‐ When you look at this place,
it's so vast,

it could be anywhere!

I've treasure hunted
all over the world.

I've seen
some amazing stuff.

Based on the photos
of the symbols that we've seen,

I knew that there's Yamashita's
treasure on this mountain.

And I want to be
the one to find it.

‐ In partnership with
the family that owns the land,

Peter and John have arranged
an introduction

to the eyewitness
known as "Grandpa."

‐ This must be the place.

‐ You must be Grandpa.

My name is Peter.
‐ Hi.

‐ I'm John.
Pleasure to meet you, sir.

‐ Here?
‐ Over here.

‐ Oh, my goodness.
There, I see it.

Look at that.

Look at all the nice
little creases

and valleys in it.

Grandpa, tell me about

the Japanese bringing
treasure here

in World War II.

‐ Was it General Yamashita
that come here?

‐ So the trucks came here.

The treasure, how‐‐

how did it
get up the mountain?

‐ Grandpa said
that the Japanese Army

cut a road
into the mountain.

Now, if we can find
that same road,

it would certainly
make finding a way

into the mountain
a lot easier.

‐ Came from where?
Wh‐which?

Point where they
came from over...

‐ In that point.
‐ From over there.

‐ Yes, from over there.
‐ Okay. Very good.

‐ Boxes?

‐ Many, how many?

‐ You cannot count them?
‐ Yes.

Peter: According to Grandpa,

when the last treasure vault
was completed,

Yamashita set off a series
of dynamite charges...

trapping his engineers
and workers

inside the tunnels.

This mountain has
one unique thing about it.

It's something that
the locals call Breach 6.

John: Breach 6 is supposedly
a dig site

that was dug by previous
treasure hunters

looking for a tunnel.

From what we've heard,

for whatever reason,
they stopped digging.

We just don't know why.

‐ Grandpa, tell me
about this Breach 6.

How can I find it?
Where exactly is it?

What...what, what
should I look for?

‐ Pyramid.

Was Breach 6
near the pyramid?

‐ Very near.

‐ Danger?

‐ These people got sick

when they were
digging Breach 6?

‐ Thank you, Grandpa.
Thank you so much, okay?

This is a dream
of a lifetime.

We have a tool,

an eyewitness that
survived from the war

that can give us clues
on how to find the treasure.

‐ At base camp,
John and Peter

meet up with the remaining
four members of the team.

‐ Brad,
certified crane operator,

certified excavator.

He goldmines in Alaska.

‐ We need him to dig a hole,
he'll be there to do it.

Welcome to the jungle.

Manny,
he's ex‐military.

Manny's job is
to keep us safe.

‐ There's fresh coconuts
out the back door.

‐ Yeah, I wonder how many snakes
are down in here too.

Jeremy,
he's from West Virginia,

so he's a coal miner.

When we need some heavy lifting,

I'm gonna count on him
to take care of it.

‐ Hey, Martin!

‐ Well, how y'all doing?

‐ Martin's an expert
in treasure symbols,

all different types,

Spanish, Japanese, Jesuit.

And he's here
to help us determine

what these symbols mean

and how we can get
to Yamashita's treasure.

Come on, we'll get you
out of the rain in our porch.

‐ So, Pete,
what's the plan?

‐ This is a view
of our mountain.

We're...we're right there,

and our object is to go out
and find Breach 6.

‐ Where are the roads they
brought all the treasure in?

‐ Probably buried under
that canopy somewhere.

‐ Did Grandpa give us
a starting point?

‐ The pyramid.

‐ In The Golden Lily code,

a pyramid means
it's a major treasure site.

‐ So we're systematically

going to go
up the mountain

and look for the pyramid
and Breach 6.

We'll spread out
and work our way up,

looking for signs
and symbols.

‐ In search of the pyramid,

Peter is leading his team
north‐northeast

as Grandpa suggested,
along a steep ridge

that rises up the side
of the mountain.

‐ You guys all right
back there?

‐ Can you believe
how dense this is?

‐ But thick foliage is masking
any obvious landmarks

or markers.

‐ What the hell
is this stuff?

Some kind of thistle grass.

It's really, ouch!
Spiny.

Hey, Brad!
‐ Yeah?

‐ Where's your machete?

Can we make a pass right
around the backside of this?

‐ Oh, man, I tell ya.
Can't get back...

‐ Right there?

‐ What the hell?

Hey, John, come here!

You gotta check this out.

‐ Oh, wow.
‐ Can you see that?

‐ Yeah.

We should take
some pictures of this.

‐ Oh, that looks
like a heart.

‐ Oh, yeah.

Yeah, that really looks
like a heart right there.

That's for sure.

What does a heart mean?

‐ Maybe it's showing us a way.
‐ There you go.

‐ In The Golden Lily Code,

hearts are believed
to be a directional marker.

‐ Martin, we're talking
about going back 70 years.

Can you tell
if this is hand‐done?

‐ I think so.
It's not jagged.

It's cleaned and cut out
and made that way.

Could be a way to lead
to the pyramid.

‐ I love that theory.

‐ Well, let's
keep trekking up.

See if we can
get a better view.

‐ So we're
in the right area.

Probably? Maybe?

‐ Hang on a minute.

‐ Holy crap!

‐ Now that's
a frickin' pyramid.

‐ I've never seen
anything like this.

Do we have
a genuine site here?

‐ Absolutely, yeah.

‐ The key eyewitness
known as Grandpa

says he saw
Yamashita's men

carrying many crates,
possibly containing treasure,

into this mountain.

‐ Let's look around.

‐ Grandpa said the pyramid

would mark the location

to an abandoned dig site

known as Breach 6.

‐ Holy mackerel!

Holy cow!

Watch it, guys.

Don't get too close
to the edge now.

‐ Look at the size of this.
‐ Oh, my gosh.

‐ This is Breach 6.

‐ The identity of those
who dug Breach 6 is a mystery.

The theory is they were
trying to dig a vertical shaft

to intersect
underground tunnels

allegedly dug
by General Yamashita's men.

According to Grandpa,

these tunnel entrances
were closed with explosives

and protected
by booby traps.

‐ That's a hell
of a drop down there.

‐ No doubt. I can't even see
the bottom from here.

‐ No, I can't.
I'm looking over the side

and I can't see it either.

‐ This is a big hole.

‐ This is a big hole.
‐ Lot of digging.

‐ How long you think
it might've taken to dig this?

‐ If you would
have 40 or 50 people,

it would still take
a couple of months.

‐ This is...this is huge.

‐ You've seen
a lot of holes dug.

Would you dig a hole
like this by hand?

‐ Not unless
I knew for sure

there was something
down there.

‐ Guys, we're gonna pick up

right where they left off,
right here. This is...

‐ You want us
to go down there?

‐ Well, I don't want
to go down there right now.

‐ I don't think it will be safe.
There could be traps under here.

There could be bombs
under here.

Who knows
what's under here?

‐ The traps set by Yamashita

may be more than legend.

In recent years,
numerous reports have surfaced

of treasure hunters

found in tunnels
around the Philippines

killed by booby traps.

Most notably toxic gas,

sarin, methane
and hydrogen cyanide

were known favorites
of the Japanese Army.

‐ So, what's the plan?

‐ Most likely,

there's something right
here in this area.

The hole may be the entrance

that goes all the way
through the mountain.

‐ We need to come back
with a probe camera.

We don't want to risk
going down there

without knowing what's
inside this hole.

‐ Now that Grandpa's
information

has led Peter and John
to Breach 6,

they reexamine
their expedition maps

to plot their next move.

‐ How old is this map?

‐ 1990.
‐ 1990.

So this map
isn't enough for us.

‐ Yeah, we need something
a little bit older.

‐ Yeah, I agree with you.

We need to see this mountain
as Yamashita saw it.

Bingo may be able
to help us with that.

‐ To locate old
war maps quickly,

Peter and John reach out
to their head researcher,

Bingo Minerva,
back in the United States.

‐ Bingo's our
head researcher.

His family grew up
in this very area.

He knows this mountain
pretty well.

‐ Hey, you guys.
‐ Hey, Bingo. How are you?

‐ Good.
How are you guys doing?

‐ You know,
we have a problem.

We need some better maps.

We need something
that's older,

70 or 80 years old.

We need something

that Yamashita may
have had in his hands,

something that would give us
a better perspective

of what he was looking at
when he looked at the mountain.

That's what we need.
‐ Yeah? Got it.

Let me go see what I can
turn up for you guys.

‐ Knowing the dangers
of Breach 6...

The next day, the team
returns to the pyramid

with a video probe
equipped with a gas detector

to investigate what's
at the bottom of the shaft.

‐ We're gonna see the bottom
of this damn hole.

And this camera's
gonna help us do it.

It's a really versatile
piece of equipment.

‐ Well, how are we gonna
see what the camera's seeing?

What they got for that?

‐ Well, you got a wireless...

‐ Wireless monitor, cool. okay,

‐ We can clip the gas detector
right on the cable

and see if it goes off.

I think we should send
the gas detector down there

before we do any excavation.

We can't see all the way down
into the bottom of Breach 6.

And there could be gases
or something in there.

Camera working?

‐ Yep.
I can see in your mouth.

‐ Ready to go in the hole.

‐ If Yamashita's men
rigged this tunnel

with a gas booby trap,

an alarm will
alert the team.

‐ Going down, Brad.

‐ Good.

‐ That's a good shot
right there.

What is that?

‐ This gas detector,

if it starts to beep
on the way down,

we know that there's
some bad air down there.

The faster the beep,

the higher the levels
of toxic gases.

Right now, it's beeping
at a normal level.

‐ Hold it right there, John.

Look how smooth that look

compared to all
the rest of 'em.

‐ Look at that.
‐ Yeah.

‐ As we're sending
the pro camera down,

we're starting to see
what appears to be man‐made.

Now we're really intrigued.

‐ That could be some cement
that was put in there.

‐ The Japanese were infamous
for using bunker‐grade concrete.

That would mean
it could be a plug,

or it could be the wall
of the tunnel.

It's really hard
to say at this point.

‐ Concrete is a signature

of Japanese Army
tunnel construction.

On islands like Iwo Jima,

the Japanese used
a unique cement mix

to build an 11‐mile
network of tunnels

and underground bunkers
to protect them

from the impending
American invasion.

The discovery of similar
cement here

could mean the Breach 6 shaft

really did intersect
a series of Japanese tunnels.

And diggers were on the right
track before they died.

‐ That is just
a great find, guys.

Great find.

‐ I'm gonna go down
a little deeper.

[ beeping ]

The beeping noise
is getting more intense.

That means there's
dangerous fumes down there.

Is it a piece of glass?

‐ Looks like a broken bottle.
‐ Holy [ bleep ]!

ok at !

Guys, we have a problem here.

‐ Inside the shaft
called Breach 6,

the team looking
for General Yamashita's

World War II treasure

has detected what
could be contaminated air

and now has just discovered
a mysterious bottle.

Grandpa, the key eyewitness,

says an unknown team

dug Breach 6
years after the war,

reportedly searching
for a tunnel...

but in the process
was killed by poison gas.

‐ Well, what could that be?

‐ It could be
a cyanide bottle.

‐ Cyanide bottle?
Do they come in bottles?

‐ A small bottle like that?
Cyanide?

‐ Possibly.

‐ It's believed
General Yamashita

used various booby traps
to deter looters

from reaching the treasure.

Some reports say
he ordered his men

to lace the tunnels
with cyanide

he kept
in small glass vials.

If anyone attempted
to breach these entrances,

the traps would
be triggered.

And the slightest concentration
of hydrogen cyanide

could kill them instantly.

‐ This definitely will
hamper our investigation.

Breach 6 is possibly
contaminated.

Pull the camera up.

‐ While the team plans

how to further
investigate Breach 6,

head researcher,
Bingo Minerva,

is on his way to Stanford
University in California.

He's looking for maps that date
closer to World War II.

By 1944, the Japanese Army
was losing the war.

But instead of
concentrating their defenses

on mainland Japan,

they sent their top general,
Tomoyuki Yamashita,

to the Philippines.

According to legend,

he would soon shoulder
a great responsibility

to ensure the bounty
looted by The Golden Lily

from the temples,
bank vaults and museums

across Asia did not fall
into allied hands.

Arriving at Stanford,

Bingo is set to meet
with Dr. David Fedman.

Fedman is one of the world's
leading authorities

on Japanese wartime maps,

and is familiar
with Yamashita.

‐ So these maps do offer,
I think, an opportunity

to put ourselves
in the shoes of someone

like Yamashita during the war

as he was using these maps
on the ground.

‐ Is there anything
particular that stands out?

‐ Here we have
the classification

of the map itself.
‐ Okay.

‐ "Top secret."

‐ So what was the year
this one was produced?

‐ If we begin to read
this passage here,

it tells us this map
is from 1938 into 1939.

‐ A 1938 map

suggests the Japanese
might have been planning

something in the Philippines

three years before
their 1941 invasion.

‐ A lot of the information
added to this map

was gathered through
covert intelligence.

‐ Wow.
‐ Yamashita and those around him

quite likely were using
maps such as these

to think about where
he might stash away war loot

in the closing months,
weeks of...of the war.

‐ That's some crazy stuff.

So is there anything
on this map that you can see?

Any kind of identifier
that just jumps out at you?

‐ Uh...

this is a "packhorse"
pathway

that leads up
into the mountains.

Something was being hauled,

and it doesn't
necessarily specify what.

But we can only speculate.

‐ Grandpa spoke of a road

the Japanese forces
built into the mountain.

If they knew about
the packhorse trail,

it's possible Yamashita's men
used this same route

to transport crates
into tunnel systems.

‐ Interestingly,
if you follow this pathway,

it just stops there.
‐ Oh.

‐ Why don't we compare
this map to satellite images?

Here we go.

So this is the digitized
version of your mountain.

‐ This horse path is the one
that really intrigues me.

I want to see if we can
find out more about that.

‐ There is
no packhorse trail at all.

There's really nothing,

no indication of any route
through this particular area.

‐ The path is likely
overgrown today.

But knowing where it was
may help the team find it.

‐ Wow, that's really cool.

‐ Sounds like your mountain

is well worth
further investigation.

‐ Meanwhile,
back at base camp,

the team figures out
how to safely explore Breach 6.

Earlier, they discovered
what they believe is cement

in the side wall.

The team thinks this
could be a concrete cap

sealing an entrance
to a tunnel.

But upon finding
a potential cyanide bottle

at the bottom of the hole,

their investigation
was put on hold.

‐ So the bottom line is,

there still could be
cyanide or explosives

in Breach 6.

‐ We still definitely
need to go down there

and get a closer look
at this concrete cap.

‐ I'm still reluctant
to send a crew down there

to start exploring.

There's gotta be a better way

of seeing what's down there.

‐ I think we should send
the infrared camera down first.

It'll see any
temperature changes.

So if that's manmade concrete,

it'll be cooler in temperature
than the surrounding.

Brad, if you put
your hand on the tree

for a couple of seconds.

All right, take it away.

You can see, like,
the color variations.

Everything that's hot
will go red,

and everything that's cool
stays blue.

‐ That is cool.

‐ So we can do that first.

And then if there's
something to be said

about this concrete cap,
you know,

then we can go in
and excavate it out.

That'll clear the air

and we'll get a firsthand look
at it then.

‐ I like that idea.

‐ Here we go.

‐ As the FLIR camera goes down,

if there's concrete
down there,

that should radiate cold.

And that'll show up
as blue.

And that's what
we're looking for.

‐ Got a visual?
‐ Yep.

‐ So we have like
an orange right now.

So I have all reds,
all reds and oranges...

Whoa, whoa, whoa, wait,
wait right there!

Hold it there!

It's turning
a purplish‐blue.

It's pointing to me?

‐ Yeah.

It's turning.

‐ Facing towards
the pyramid right now.

‐ Well, that's when
you're picking up

the colder temperatures,

between me and the pyramid,

where the coldest
temperature's so far

going down the wall.

Look at this.

Look at that.
Look at that.

The dark blue.

We found a change
in temperature

radiating out
of the side wall

that lines up
with the pyramid.

Could be a concrete cap.

Could be a side tunnel

going right underneath
our pyramid.

That's exciting, guys.

‐ It is. [ laughs ]
‐ That's something else.

There's something there,

and we're gonna find it.

‐ So what do you wanna do now?
‐ I want to dig.

I want to dig right here.

I want this
to be our work site.

All right?
Let's get the excavator.

Let's make this happen, guys.
I want to see what's down there.

‐ All right.
Let's do it.

‐ Now that the team
has found evidence

of a possible side tunnel
intersecting Breach 6,

the excavation process
can begin.

The plan is to open up
the side of the shaft

to vent any potential gas,

allowing direct access
to the suspected concrete cap.

Back at base camp,

Bingo shares a new lead

he uncovered
while at Stanford.

‐ I was able to find
a map of our area,

and here's the cool thing.

At the very top of it,
it's labeled "top secret."

There was a trail that
leadeth off into our mountain.

There's handwritten details
in Japanese text.

And it says that it was
a packhorse trail.

‐ This could be the trail
that Grandpa used.

That trail was probably
used by carabao

taking boxes up
to the top of the mountain.

‐ It could be
that same trail.

‐ Using coordinates
from Bingo's war map,

John and Manny
head into the jungle

to search for the mysterious
packhorse trail

possibly used
by the Japanese Army

to haul treasure
up Grandpa's mountain.

If they can locate the trail,

it could lead them
to an entrance

into the mountain.

‐ Manny, keep your eye open
for an old trail.

‐ In the decades
since World War II,

overgrowth has obscured
any sign of a trail.

And even though John and
Manny are in the right area,

locating the packhorse
route won't be easy.

‐ You okay?
‐ Got it.

‐ You know, the Japanese
didn't want you

to find their treasure.

But one way or the other,
we'll get there.

We're not gonna give up.

Manny, this looks like
an old wash or something.

‐ Yeah, looks like a creek.
‐ Yeah.

I don't think
it's a creek.

I actually think it's
like a trail of some sort.

‐ There you go!

‐ It's a pretty
damn wide trail too.

This is where Bingo
said it would be.

‐ John and Manny may
have just discovered

what could be
the pack animal trail

Grandpa says
General Yamashita used

to move crates
up the mountain.

‐ What do you got?
‐ I got 12'6".

This road is
definitely wide enough

to drive a Japanese
truck up.

Manny, let's see
where this road goes.

Manny.
‐ Yeah.

‐ It looks like
the road stops here.

Like they...
like they pushed it up,

and then just pushed it to there
and that's it.

Look what you're standing in.

Everywhere we look,
just fractured rock.

These rocks, even.
Look at this one here.

Look at how it's just
shattered to death here.

‐ I got some broken
pieces here too.

‐ I know.

See how it's nice
and round on one side?

‐ Yep.
It's all over.

‐ I've seen a lot
of heavy highway work

where they actually
blow the cliff face off.

And the rocks
were just like that,

really cracked,
angular, sharp rocks.

And remember
what Grandpa said.

You know, Grandpa
heard the explosions

going off the mountain.

The Japanese told him,

we'll kill you
if you dare come up here.

There wouldn't be...

it wouldn't be
fractured like this

if just nothing happened.

It just doesn't fit in
with this jungle.

It should not be here.

So the only other thing
that it can lead to

is that this was an entrance
into the mountain.

The trek went freakin'
awesome, Pete.

You're not
gonna believe this.

We actually
found this trail.

It's not
a pack animal trail.

It's a road,
and it's like 13 feet wide.

‐ Yeah, the fact that
you found a road up there,

we're not talking
about pack animals anymore.

We're talking
about vehicles.

We're talking
about trucks.

‐ Yeah, and it verifies
what Grandpa said.

But it actually takes it
to a new level now.

You can move a lot
of treasure across this road.

So that little bit of treasure
that I may have

thought came up on carabaos
and horses is now....

‐ So you're talking
tons and tons of stuff

going up this road.

A lot of treasure
coming up into this mountain

for them to even think
about building a road,

like just the engineering
alone to do that.

It had to be something
worthwhile to do it.

That makes this treasure

way bigger
than we even thought.

‐ Massive.

‐ While the exact scope
and value of Japan's war loot

remains a mystery,

it is estimated
Yamashita's treasure vaults

contain untold billions,

possibly even
a trillion dollars

by today's gold standards.

That total doesn't include
the priceless artifacts,

religious relics

and even plans
for top secret weapons

allegedly stolen by
the Japanese Imperial Army.

The Nazis conducted
a similar looting campaign,

prompting many European nations

to keep their valuables
in Asian banks,

never suspecting they
can fall into the hands

of the Japanese Army.

‐ This treasure
could be massive.

‐ Absolutely.

‐ So with that said,

where is Breach 6

and the pyramid
in relation to your road?

‐ It's actually
pretty close by.

If you go up the mountain,
say another say 250, 300 feet,

you know, here you have
the pyramid rock

and you got Breach 6,
you know, right next to it.

It's weird, though,

cause the road
goes right along

and then it kinda
hugs the mountain.

Then all of a sudden,
whoosh, it dead‐ends.

You know, maybe somewhere
along the line

they actually had a tunnel
that went into the mountain.

They blew it closed
and it all came crashing down.

‐ I wonder if there's
any connection

between the pyramid
and Breach 6 with your road,

considering that it's
so close in proximity?

‐ It could be the reason

why they dug Breach 6
to begin with.

Maybe they were going
after this collapsed tunnel.

And maybe our road actually
does connect to it.

‐ I‐‐I like that idea.

‐ The question we have
right now is,

what is the best way
to get inside this mountain?

‐ We gotta get down
in that hole and find out.

The story
and the treasure itself

is getting bigger
and bigger.

All right, guys.

Let's turn this jungle
into a job site.

‐ To avoid any booby traps
or potential poison gas

at the bottom of the shaft,

Peter and the team
are planning to access

the possible concrete cap
from the side

instead of from
inside Breach 6.

‐ Let's clear out all
of those weeds over there.

‐ Before excavation
can begin,

the area is cleared
for heavy machinery

with the approval
of landowners

and local officials.

‐ Look at this.
What is that?

‐ Looks like a chisel mark.

‐ John!
‐ Yes, sir?

‐ Come over here, please.
‐ What'd you find?

Peter! Hey, Pete!
Check this out.

They found some box markers.

‐ In The Golden Lily Code,

a "box marker" usually
signifies a vault.

The number of boxes will
indicate the number of vaults.

To date, at least
26 different variations

of box markers
have been identified.

The markers'
proximity to Breach 6

could point to vaults buried
deep below.

‐ There's two right here.

Square marker hole,
square marker hole.

‐ This is definitely man‐made.

‐ There's something
right here in this area.

‐ This is really a remarkable
indentation in the rock.

There's something
underneath it.

Or maybe the rock
was over there.

And they moved it over there
so they could dig.

John: It's possible.

This marker may have sat
directly on top of Breach 6.

‐ This is where
we're gonna be digging.

You'll make that happen?
‐ I'm going to.

‐ All right,
thank you guys. Let's go.

‐ To avoid any potential
poison gas in the hole,

heavy equipment operator,
Brad Carr,

intends to use
the team's excavator

to open up the side
of Breach 6

to verify the existence
of a cement cap

in the wall
of the mysterious shaft

which could provide
a way to access

a potential tunnel network
buried within the mountain.

‐ Here we go!

Breach 6 is about
to become Breach 7.

‐ At Breach 6,
Brad breaks ground

next to the giant shaft
that could prove to be

the team's entrance
into the mountain.

The theory is
that Yamashita's men

allegedly dug a network
of horizontal tunnels

and hid the treasure there.

After completion,

the surface entrances
were sealed by an explosion.

‐ How big do you think
the tunnel is, John?

‐ It don't matter
how deep it is.

We get there.

‐ That's for sure.

A lot of people
that did come

and search
for this treasure,

they dug the hole.

The chemicals got to them

and they died in the hole

because they just
weren't prepared.

We have to be very careful
how we proceed with Breach 6.

This is serious stuff.
You can die.

‐ To avoid triggering
any potential booby traps

and what might
be contaminated air,

the plan is to excavate
alongside the hole

and lower the excavator
down in steps.

Once the side wall is open,

they can safely dig
straight into Breach 6.

Jeremy: Hey, why's it look
like you're makin' a mess?

‐ Just for you.

‐ Yeah, I'll have it
cleaned up in no time.

Definitely keep an eye out
for signs and symbols because...

‐ All right.

‐ The team is finally ready

to peel open the side
of Breach 6

in order to vent
any dangerous gases

possibly still lingering
inside the hole.

‐ Well done!

‐ To dig down the 45 feet
needed to open Breach 6,

Brad and Jeremy continue
working through the night.

‐ Now all the real work starts,
that's for sure.

‐ Excavation is now level

with the potential
concrete cap,

allowing the team
their first clear look

at the possible entrance
to a side tunnel

extending under the pyramid.

‐ You gotta get over here
and take a look at this.

‐ It's exciting. [laughs]
‐ On our way.

‐ You guys did
a hell of a job!

Wow.
Oh, yeah, look at that.

Oh, you're 10 feet
from the bottom.

‐ It's still a long ways
down there.

‐ Look at the difference
in that rock,

as opposed to everything
else around it.

It's definitely
a different texture.

‐ It looks like nothing else
around here at all.

‐ Let's get the excavator
in here and tear it up.

‐ We can do that.

‐ And if there is
a side tunnel there,

you can be the first one
to go through it.

‐ I'll rip right through it
and go right into it.

‐ Let's make it happen.

‐ It's...it's
pretty tight, John.

I don't know if
I'm even gonna fit.

‐ Yeah, you only
got like 10 inches

off your right track
to the wall.

Go ahead.

Keep going.

Two feet of clearance
on the counterweight.

‐ All right, here we go.

I'm gonna punch in right now.
‐ Go for it, bro.

‐ Been here for days
just for this moment.

‐ This season on "The Lost Gold
of World War II"....

‐ We have a new technology
that's coming in.

It's called LIDAR.

‐ Ooh.
‐ There are the trails in there.

‐ In all my years
of treasure hunting,

I've never seen
X marks the spot.

‐ Maybe the cave
on our mountain

was one of Yamashita's
headquarters.

‐ Yamashita didn't make
anything easy for anybody.

There was a waterfall

and something that looked
like a monkey head

behind the waterfall.

‐ You see that?
See the hexagon?

And that's showing you
there's treasure in here.

‐ Holy [ bleep ]!
‐ What do ya got?

‐ This has been
worked in here.

This could be
the back door.

‐ That could be good or bad.

‐ What do you mean?

‐ It could be a bomb in here.

‐ Ah, dammit.

‐ Constantly fighting
Mother Nature.

Mudslides are getting bad,

could wipe us right
off the hill.

‐ Timber!

‐ Absolutely incredible.
Thank you.
