Original subtitles

‐ Did you see Mr. X?

‐ I did. You got to listen to this.

‐ What is this?

‐ Keep it coming.

‐ Announcer: John Casey,

a construction contractor from the U. S.,

is back in the Philippines with a new team...

continuing his search for Yamashita's gold.

‐ We're gonna find a way to get to this treasure.

‐ Like many others,

John believes Japanese general Tomoyuki Yamashita

took billions of dollars in treasure

looted by Japan in World War II

and hid it in the Philippines,

including somewhere inside this mountain.

‐ The Japanese, they bring the boxes up the mountain.

‐ According to an eyewitness,

mysterious wooden crates were hauled up this mountain

by prisoners of war

and buried in tunnels, which were then destroyed.

‐ ...boom.

‐ Based on that account,

John followed a series of mysterious symbols

to three promising sites‐‐

a waterfall...

‐ This waterfall's hiding something.

‐ ...a crater known as Breach 6...

‐ I've never seen anything like this.

‐ ...and a camouflaged tunnel they uncovered last year.

‐ We are in the mountain, boys.

‐ Can they finally discover the...

‐ This place is totally overgrown from last year.

‐ With monsoon season over,

John Casey is ready to pick up where he left off,

and he's got a new crew,

including his brother Rob.

‐ We're back on the mountain,

and I'm taking Rob over to the tunnel.

This was the biggest find we had last year.

This tunnel could possibly lead us

right into a main network of tunnels

that goes throughout the mountain.

You know, for me, it's not about the money.

Treasure hunting is a passion.

That gold, it tells a story

of the people that lost their lives,

you know, for that treasure to even be where it is.

You know, and that's what we're trying to do.

We're trying to uncover the truth.

We get that treasure out,

that could change what we think about World War II.

Oh, this is not looking so good.

So totally overgrown, you wouldn't even know

that there was a tunnel here.

‐ That looks really tight.

‐ Looks like it's collapsed a lot.

‐ [ sighs ]

It looks extremely unstable.

‐ I expected, when I was bringing Rob up here,

that we were just gonna walk back into the tunnel

like last year.

But the mountain had different plans for us.

‐ The mudslides from torrential rains

have blocked the tunnel‐‐

an unexpected setback.

‐ You know, last year, when we were here,

we threw some smoke bombs in there.

‐ Fire in the hole!

‐ Coat it with a tarp.

We waited to see if the smoke came out anywhere.

‐ Look! ‐ What?

‐ So all the smoke plumes we saw last year

could indicate that there's a tunnel system

that goes deep inside the mountain.

You have those smoke bombs with you in the bag?

‐ Yeah. ‐ Let's do that.

Let's put the smoke bombs in,

cover it up with the tarp,

send the drone up.

Wherever the smoke comes out in the mountain,

we'll do to that spot and see

if that's an entrance to get in.

Head straight for the gully right in there.

Yeah, right about there

is where we saw the smoke last time.

I'm not seeing any smoke. ‐ Me, either.

‐ I can't see anything right now.

‐ What does that mean? What are we gonna do?

‐ There must be more than one collapsed in that tunnel

because we should be seeing smoke by now.

‐ Yeah.

‐ 'Cause we have five different spots of smoke

coming out of there.

Now we got nothing.

The mountain is really stacked up against us

at this point.

‐ John and Rob head back to basecamp

to meet with the rest of the team.

Joining the hunt are father and son miners

Geo and Levi,

geophysicists Max and Colin...

And Rick Hurt‐‐ ‐ It's great to see you.

‐ ...who searched this mountain 20 years ago.

‐ You guys, welcome to the Philippines.

I appreciate y'all coming out here.

We traveled halfway around the world

to go after one of the largest treasures

in modern history.

I acquired some information

that's gonna help us find that treasure.

It's called nuclear magnetic resonance.

Through a contact that I have in Russia,

uh, who has access to the satellite system there,

they were able to commission a scan of our mountain

that would show any metal anomalies

or any metals underground whatsoever

at this location.

‐ Nuclear magnetic resonance, or NMR,

is an advanced satellite scan technology

that uses targeted frequencies

to detect large underground metal deposits.

‐ You know, I've seen this stuff used before

to find precious metal deposits in mining,

and it definitely works, man.

‐ Rob, if you'll run the slide machine,

we'll tee up some of the scan.

‐ Yep. It's showing.

‐ Whoa. ‐ Wow.

‐ That's impressive.

‐ You can see that the satellite made multiple passes

and picked up multiple targets.

This is the one that sticks out the most to me.

It's multiple hits all in one spot,

right on the waterfall.

All the signs and symbols were pointing last year

to the waterfall,

and I believe there was a treasure under there.

[ gong sounds ]

‐ John believes these symbols were created

by the Golden Lily,

a secret society of Japanese nobles

and royal family members

who allegedly orchestrated

the looting and burial of treasure.

‐ Now the satellites, you know,

are actually showing

that there's a huge target hit there.

‐ That's awesome, man.

‐ That's cool. ‐ It really is.

‐ And that gives you an idea

of the depth, too?

‐ It won't give us the exact depth,

but we'll bring a tech team in,

and they'll help us narrow the playing field down.

So they'll tell us exactly where it is

and the relative location the satellite pinpointed.

Along the bottom here we got this line.

The weird thing is

is that Breach 6 sits right in the middle of this.

‐ Breach 6 is a site further down the mountain

with a deadly history.

According to an eyewitness

who was a child during World War II,

the Japanese planted a booby trap in the area.

Treasure hunters were digging a shaft

down to what they believed was a treasure vault

when they reportedly triggered the booby trap.

Though many have tried...

To date, no one has been able to access

what lies beneath Breach 6.

‐ Whatever is on that line is pretty significant

metal‐wise.

It could be metal boxes of things.

Could be, you know, munitions.

Could be trucks. Could be a lot of different things.

But whether they're actually in a tunnel

is really hard to say at this point.

‐ You don't think that's possibly

an ore vein of some sort running across there?

I would think not

because, "A," it wouldn't be so straight.

And if there was more ore on this mountain,

it would be elsewhere,

and they just didn't get it there,

so it's looking like it's just across this bottom side

with Breach 6 smack dab in the middle.

But, Rick, you know,

I think that starting right here at Breach 6

might be the way to go.

‐ Never in my wildest imagination

I ever dreamed I'd be back here.

Left here 20 years ago.

I felt like I left a job undone.

I'm ready to get the treasure.

We're gonna finish the job.

‐ So where does that leave us at?

‐ It's not here on the map,

but last year we found a tunnel.

It was collapsed.

If you can open that tunnel up,

it could lead to everything.

All right, guys,

these are our three main targets‐‐

waterfall, tunnel site, and Breach 6.

Let's get at it. ‐ Rob: Yeah.

‐ The team disperses across the mountain.

Miners Levi and Geo are charged

with clearing the tunnel.

‐ Okay, I'm gonna start moving some dirt.

Make sure you're clear. ‐ Okay.

‐ Once we get the vegetation scraped off,

we'll move the dirt that's there that was closing this thing off.

They we can actually open this tunnel up

and actually see what the heck we have inside this thing.

This ground is super moist and super freakin' muddy,

so there's a potential

that this dirt and rock can slide down the hill,

and I don't care what anybody says.

These rocks don't care about your feelings.

‐ Not a lot of hard rock yet, is there?

‐ We got to stop for a minute here.

We got to take a look at this.

‐ What have we got?

‐ I don't know. Look at that.

What the heck is that?

‐ Well, this thing here's strange.

I don't know what the heck this could be.

I don't know if this was a gate for the front of it

or if they had it for support in the back of some sort.

‐ We've got round stock here, too.

‐ Yeah. ‐ From the posts in the back.

‐ Looking at the round stock,

to me, that's a told‐tale sign that this thing is old.

Usually in the old days,

when they were in a hurry to put these mines up,

they'd go‐‐ go out in the woods.

They'd saw a tree down.

They'd take it, cut it into length,

take it right inside of the mine,

and use it for ground support.

We'll roll this thing over,

and then we're gonna look at it.

That way, we can see the bottom of it.

‐ It's a friggin' gate, isn't it?

‐ Boy, it looks like a gate. ‐ It is a gate.

It's a big heavy‐duty gate.

‐ You're absolutely right.

That's an old hinge. That's a very old hinge.

And look at all this old, old round stock.

This stuff is...old.

‐ I don't know how old that lock is that's on there.

‐ Oh it's got a lock on it, too.

‐ The gate looks way older than the lock.

We were expecting to be the first ones

to step foot in here in the last 50, 60 years,

and clearly that's not the case.

Somebody else has been in here.

Them putting a lock on it,

to me they were trying to keep somebody out of here.

Bottom line is, until we get inside of this tunnel,

we're really not gonna know what the heck's going on.

Don't know who's been here.

But I'm gonna find out.

‐ On a remote mountain in the Philippines,

a team of Americans is searching

for Yamashita's gold.

Based on a recent satellite scan,

they think some of this treasure

may be below a location known as Breach 6.

Rick Hurt's been haunted by that location

since he first came here two decades ago.

‐ My profession is precious metal extraction.

20 years ago, I was in the Philippines

on a project that was about silver refining.

And one day, Colonel Cariaso,

retired military guy from the Philippines,

sought me out,

asked me if I was interested in gold.

And I was like, "Of course I'm interested in gold."

According to Colonel Cariaso,

he told me that he was raised in the Marcos household.

As he got older, he went in the military,

became a very, very trusted man with President Marcos.

‐ Reportedly obsessed with Yamashita's treasure,

Filipino President Ferdinand Marcos

allegedly confiscated maps created by the Golden Lily,

the secret Japanese society

that coordinated looting throughout Southeast Asia

during World War II.

Many suspect that Marcos' declaration of martial law

in 1972

was an attempt to continue his search more freely.

It's thought that, before he was ousted in 1986

and fled to the United States,

Marcos entrusted one of those maps

to Colonel Coriaso.

‐ Marcos had been gone for quite a while.

Colonel Coriaso was working independently.

Coriaso had a map.

The map was the key to the whole thing.

You know, he wasn't sharing it with anybody.

He was keeping it really secretive.

The quick glimpse I got of the map 20 years ago

just wasn't enough time to figure things out.

I took a break to go back to the United States.

I never made it back here.

Colonel Coriaso's gone. The map is gone.

You know, we've got new data.

But it would be so nice just to have a translated map.

I could be sitting

right over the access to the tunnel

and not know it.

I've got unfinished business on this mountain,

and I need to find that map.

I don't know if Colonel Coriaso is still alive.

I haven't been able to find him.

I just keep thinking,

if I can find Colonel Coriaso,

we can maybe get a look at that map he had.

‐ So any luck on the computer?

‐Nothing, man. It's like the guy dropped off the planet.

I don't know what to do next.

‐ There was this guy that Pete met with last year,

and he preferred not to be called by his first name,

so we just called him Mr. X.

Mr. X claims that he was the heir apparent

to Bob Curtis.

‐ Robert Curtis was a Nevada metallurgist

reportedly approached by Ferdinand Marcos in 1974

to take part in a recovery expedition

of Yamashita's treasure.

Like Colonel Coriaso,

Curtis allegedly had access to Marcos' maps.

The team believes that, before he died in 2004

of unknown causes,

Curtis may have passed some of the maps

along to the confidential informant

they call Mr. X.

‐ You inherited some maps, didn't you?

[ voice distorted ]

‐ He was privy to all the maps that Bob had.

He was able to view all the maps.

You know, it is a longshot.

Maybe we can get a hold of him, get you guys hooked up,

and maybe by some miracle

you could sweet talk him into even letting you see it.

‐ Oh, that would be awesome.

‐ While John and Rick try to track down Mr. X,

tech team Colin and Max go to the waterfall

to pinpoint the location of the massive metal deposit

picked up in the NMR scan

that John believes

could possibly be a treasure chamber.

‐ At this location, John needs us

to find some sort of void space

underneath the waterfall here.

The seismic survey is probably our best chance of doing that.

All right, should we start laying

some seismic cable, Colin? ‐Yep.

‐ Seismic is kind of like an ultrasound

for the earth.

We send sound down into the earth.

Sound bounces off all of the cracks,

all of the voids,

and it comes back.

Colin, that's probably good.

‐ The timing of all the different vibrations

are sent to a central computer.

Our computer does some fancy math

which will tell us what's underneath us

and pinpoint exactly where it is.

‐ Seismic testing is derived from the sonar technology

that gave Allied forces a prominent edge

confronting the enemy during World War II.

[ pinging ]

Relying on sound pulses called pings,

sonar helped the Allies dominate the Pacific seas...

destroying 128 of Japan's 174 submarines.

‐ Max: All right, I think we're almost ready to roll.

‐ We use a sledgehammer as our sound source.

‐ [ whistles ]

All right, fire it up.

Looks good.

Okay.

‐ Large‐scale seismic surveys

can see as far as 3 miles into the ground.

But thanks to the restricted space at the waterfall,

the tech team's range is limited

to about 500 feet.

‐ Five hits here, and then we'll pack up.

Ooh. Good one.

Nice.

‐ Even though we got all this super‐expensive equipment,

we're still just smashing a hammer on a steel plate.

‐ Early the next morning,

miners Levi and Geo continue working on the tunnel.

They need to install a support fence

to prevent any rockslides as they dig out the entrance.

‐ I'm freakin' jacked, man.

We got the fencing in. We're rock and rolling now.

‐ With the surrounding area secured,

the miners can now safely begin

excavating the tunnel entrance.

‐ I can't even comprehend what‐‐what‐‐what's ahead of us.

I want to get inside here and take a look

and see what we have.

‐ It's looking good.

Not much yet. A little bit of brow.

About a 6‐inch hole.

‐ Ah, we're starting to get her opened up here.

Oh, yeah. We're just inches away.

Here we go.

Looks like we're there, Geo.

‐ Finally.

‐ Wow. This is pretty exciting, huh?

‐ Oh, it's definitely exciting, man.

You got a light?

‐ Yeah, let's take a quick look in there.

This is an old tunnel.

‐ It's in better shape than what I was expecting.

‐ Yeah. Look at all the round stock and everything.

It's pretty wild‐looking, huh?

‐ It's old, man.

‐ With all this mud and clay,

I'm worried about this first 10 feet coming down on us,

especially if we get some rainfall.

‐ You don't want to walk straight into this tunnel here

because there's still ground fall potential.

Wow. This ground's bad, man.

The whole world could come down on you.

Until we get it properly caught up

and bolted correctly,

you don't want to go inside of there.

General Yamashita was known for tunneling

and burying treasure inside the mountains.

They wouldn't have put that timber in there

if they didn't want this thing to last.

It's time to get in there and find that treasure.

‐ As the team on the mountain continues their quest

to find Yamashita's gold,

head researcher Bingo Minerva is meeting

with military historian P. J. Springer.

‐ Bingo. ‐ P. J.

‐ Nice to meet you.

‐ Great to finally meet you, sir.

‐ Great to meet you in person. ‐ Pleasure.

‐ He hopes to learn what types of treasure

could be waiting for them inside the mountain.

‐ So I was able to find all kinds of great materials,

particularly in the National Archives

up in Washington, D. C.

I found some phenomenal examples

of the types of loot that they're going after.

And we think of treasure,

we tend to think of gold and silver and gems.

But the Japanese are seizing all kinds of materials,

not just what we think of as traditional treasure.

You have works of art. You have religious objects,

archeological expeditions

that brought back incredible things.

And these are all looted cars

that were actually stolen

from the areas the Japanese had occupied

and taken back to Japan.

It was against the laws of war

to engage in this type of looting,

but Japan had refused

to actually sign those same laws of war.

‐ I see. ‐ As far as they were concerned,

they weren't bound by the rules

that they had never agreed to follow.

‐ After World War II,

the Allied command began the reparations process

for countries looted by the Japanese.

American forces oversaw the massive undertaking

of assessing and collecting the billions of dollars

in gold, precious metals, jewels,

and other plundered resources.

Even though billions of dollars were returned

to the looted countries,

it is believed to be only a fraction

of the amount taken by the Japanese.

‐ Do you know the total value of treasure

that the Japanese took and looted during the war

or even before the war?

‐ It's impossible to say for certain.

We don't have a consolidated record

of everything they took.

Now, from what I've been able to figure out,

you're probably looking at a total amount

of at least a hundred billion dollars'

worth of material looted,

probably more.

My conservative estimate

is maybe 20% of it has been recovered

and returned to the countries that had been invaded

and looted in the process.

‐ Wow.

What happened to the other 80%?

‐ You're talking hundreds of billions of dollars

unaccounted for,

and an awful lot of it is just a complete mystery.

‐ Now, my team's currently in northern Luzon,

and I was wondering, if they were to find any treasure,

how much do you think we would find

if we were to find anything in our tunnels?

‐ So for the purposes of your team,

if we're talking about

the northeastern portion of Luzon

and in particular Nueva Vizcaya,

in the summer of 1945,

when Yamashita finally surrenders,

that's the last place

that the Japanese are getting pushed into

for their defense of Luzon.

‐ Luzon, the largest Philippine island,

is where Yamashita made his last stand in 1945.

He lost 212,000 soldiers in the northern mountains

before finally surrendering to American forces

on September 3rd.

The surrender took place in Baguio City,

just west of Nueva Vizcaya,

where the team is now hunting.

‐ If there's a bunch of hidden gold and silver,

it's going to be in the last places

that were under Yamashita's control.

How difficult it will be to find,

well, that's up to you and your team.

‐ Back in the Philippines,

Rick's on his way to meet Mr. X,

a confidential informant that John suspects

may have access to Golden Lily treasure maps.

‐ I'm heading off the mountain now.

Mr. X,

uh, he agreed to meet with me.

I am really, really hoping,

um, that he will give us a map.

There's a lot of mountain there.

With a map, we can get honed in pretty quickly.

Okay.

We're here.

All right.

‐ Mr. X has agreed to be recorded

but asked to meet Rick in private

while the camera crew waits outside.

So Rick has been outfitted with a body camera.

‐ Hello. I'm Rick. ‐ [ voice distorted ]

‐ Nice to meet you. Thank you for meeting with me today.

Not that I know of.

Yeah. You know, I've got some guys out there working,

um, down in Nueva Vizcaya,

and we think we're on to something.

You know, I've been told that you're the guy,

and I'm really hoping you can help me with a map.

‐ At an undisclosed location,

Rick meets with a confidential informant

believed to be holding

numerous Golden Lily treasure maps.

‐ Who has the maps now?

Who controls this information?

[ voice distorted ]

‐ Who‐‐Who do I need to be worried about?

‐ The New People's Army is a faction

of the Communist Party of the Philippines.

With roughly 4,000 members,

the NPA violently targets U. S. interests

in the Philippines,

having killed several American service personnel.

It's stated goal‐‐

remove all United States presence from the country.

‐ I'm familiar with Bob Curtis.

‐ Okay.

‐ Curtis was a central figure

in Ferdinand Marcos' efforts to find Yamashita's treasure.

He was allegedly entrusted

with Marcos' Golden Lily maps...

and tasked with decoding the location

of the supposed Yamashita treasure sites.

‐ So there's just no help you can give me at all?

Wow. That looks like a lot to go through.

‐ As a new day dawns on the mountain,

John gets his first look at the reopened tunnel

he hopes connects to a network

leading to treasure.

‐ You guys did a lot of work already.

All those bolts.

‐ Looks a lot different

than last time you seen it, eh?

‐ No doubt.

Last time we were here,

I came down a tube right here

and slid right in.

Kind of stupid for going in there

without any real protection

and not knowing what we were getting ourselves into.

‐ So we'll check it out.

‐ Let's grab it and get set up. ‐ Yeah.

‐ Though the entrance is secure,

the tunnel itself is still far too unstable

for them to enter,

so Levi and Geo come up with a plan.

‐ Levi: We can go in there ourselves,

but I'd rather take this thing in there, get pictures.

If this thing gets buried and gets lost,

you're out a couple thousand dollars

rather than losing a life.

You ready?

Oh, this thing's awesome. [ John chuckles ]

‐ John: I'm looking forward to seeing

farther than I walked into last time.

There's just so much information in there

that we just need to know, you know‐‐

who built the tunnel,

if there's any markings in there,

see if there's any other tunnels in here

that go toward the waterfall.

If the Japanese left anything behind

or whoever‐‐ whoever dug this thing

left something behind, I want to see it.

‐ Just take a look at that wall right there.

‐ Is that like a chisel mark right there, these two?

‐ That's interesting 'cause it does look

like something was chiseled out of there.

You can see the rock looks like the same type of rock,

but that is such a clean cut right there.

‐ Agree. ‐ That it almost looks

like a tool mark of some sort. ‐ It does.

‐ Can you throw me some light on the other side, Geo?

It doesn't look like it's been a pneumatic drill.

Usually you get a perfectly round half barrel.

‐ Right. ‐ That's on the rib.

Them not being pneumatic drill marks,

it's looking like it was actually

hand chiseled out of here.

That's showing me that this thing can be very old.

‐ Whoa. That was a lot of work.

‐ Well, they had slave labor, though. They didn't care.

‐ Roughly 27,000 Americans

were taken as prisoners by Japan

during World War II.

It's believed Yamashita relied on those POWs

to construct his massive network of treasure tunnels.

‐ It almost looks like down the tunnel there,

like, on the posts there's, like, these numbers on them.

‐ They're American numbers painted‐‐

looks like they're painted on there like whitewash

onto the posts.

Yeah, those are not Japanese numbers

'cause I can read them.

‐ Levi: Maybe they were counting their sets

as they came in.

‐ Could mean that Americans were in here

putting this in.

What's that, a pile of rubbish in front of you?

‐ Yeah, it looks like we're coming

to a major ground fall here.

‐ What's that black thing on the floor?

‐ What is that?

‐ Is it a handle to a tool or something?

‐ There's something there. ‐ Something there.

Can we zoom in on it?

‐ Yeah. Working on it.

‐ Oh, there you go. ‐ There you go.

Now I can tell what it is?

No.

‐ It looks like‐‐ like a handle of something.

‐ It's not an old grenade, is it?

‐ I don't... ‐ It's got weird grooves in it.

‐ Yeah, it does.

‐ Oh, is that a blade right there?

‐ Oh, is that a blade right there?

‐ Looks like a knife, doesn't it?

‐ That is a knife. Look. You can see the...

‐ Yeah, it's like the shank piece there.

‐ Handle on it and everything.

‐ That's your shank that protects your fingers.

There's the blade. ‐ Exactly.

‐ And that's the end of it.

I don't know what else it would be.

‐ You think that manipulator arm's

strong enough to move it? ‐ I don't know.

You think I can roll it out of there

and get a better look at it?

‐ Try to grab a hold of it

and give us an idea what it is.

It's sure looking like that from that angle.

‐ Oh, yeah, it is.

‐ We need to get this thing out of here.

It's just like killing me.

I can't wait to see what it is.

It's really got my curiosity.

‐ There you go. It's looking right at it.

Can it come up? ‐ Whoa.

‐ It's‐‐ ‐ Oh, you flipped it.

‐ I did have it. ‐ No, you didn't.

‐ No. You were in front of it,

but now you might have it right now.

‐ Open those‐‐O‐‐ Yeah, go straight down.

‐ This is the most intense game of the claw game

I've ever played, man.

Move forward a little. Okay. Go. No. Forward.

Go easy.

‐ You got it, brother.

‐ You got it, man.

‐ We finally got a hold of this thing.

We don't want to drop it now. ‐ Okay.

‐ And there's a post right there.

‐ Okay.

‐ Ooh. ‐ Ooh. Nice.

‐ Want me to swing it over a little bit now?

‐ Yeah. Let's, um... ‐ Very careful.

‐ Man, it's hard to tell the depth perception.

‐ Yeah, you're doing real well.

‐ You're almost there. You're almost there.

‐ Oh, man, look at that. That is freakin' awesome.

Got it. ‐ Yeah, you did.

‐ It's something that's got a serrated edge

on the back of it.

Markings right here.

Looks like my Ka‐Bar.

Ka‐Bar is a military style fighting knife.

They've been used all the way back into World War I

and World War II.

They were standard issue in the Marine Corps,

and that's a lot what that handle looks like.

‐ You know, this is a really significant artifact.

If it came from World War II,

it's right in the right time frame,

and God only knows, if that thing could talk,

what it could tell us.

‐ Definitely need to get this thing analyzed.

You're holding a piece of history right there, man.

‐ Yeah, this is‐‐ this is exciting, man.

I can't wait to get inside this thing,

see what else we find.

‐ Levi: I'm a miner.

And I've found gold.

I've mined silver.

I've mined lead, all that stuff,

but it's just a paycheck.

You know, this here, this is a piece of history

I have in my hands.

It's hard saying what this knife has seen,

who carried it,

how it ended up in this tunnel.

If this was an American's knife,

he probably didn't lose it.

The reality of it is

is it was probably taken from him.

He probably was killed,

and it was probably taken as a souvenir.

That is the reality

of how this probably ended up in that tunnel.

This is my very first piece of treasure,

and I mean it.

Couldn't‐‐I couldn't ask for anything else.

The gold's awesome,

but this here has a lot of sentimental value to me.

You know, a lot of the South Pacific over here

during World War II was Marines,

and, I mean, Marines are brothers, man, you know?

You have Marines

that you don't see for 10 years,

and it's like you never missed a day, you know?

I think that's why it hit so hard home to be

is 'cause it was probably a Marine

that lost the knife, you know.

It's become real personal to me at this point.

I need to get this mountain.

We need to figure out what's going on.

‐ At basecamp,

Colin and Max present the findings

from the waterfall scans.

Numerous symbols around the waterfall

make John suspect it could be hiding a treasure vault.

He hopes the tech team has found evidence

to confirm his theory. [ beeping ]

‐ We've plotted all of our data,

and as we go in, this is your waterfall

in this area.

We did collect a seismic line.

And we found, I think,

something that you're gonna love.

‐ John's satellite scans

showed a large metal deposit under the waterfall,

so the tech team performed a seismic survey...

to pinpoint a possible tunnel entrance

to the deposit.

‐ We think we've got either a tunnel

or some type of void space.

‐ So where's our seismic data,

and it's quite deep,

um, way deeper than I thought it was gonna be,

and it's way down here. ‐ Wow.

‐ It's like about 300 feet down.

‐ Whoa. 300 feet?

That's a long way down.

But if the Japanese are burying big treasures

like the one that's up there,

it could be that deep.

‐ If it is that far down,

there's no way they dug that straight down

from the‐‐the waterfall.

They had to get at it from a different way.

‐ No one's just gonna come

and start digging to 300 feet through solid rock.

‐ They had to come in from a different direction.

‐ There would be a back door somewhere.

Now we just got to figure out how we're gonna get there.

‐ Later that night,

Rick finishes the day‐long journey

back to the mountain,

returning with a box of tapes

from the confidential informant

that could contain clues to their mountain.

‐ Did you see Mr. X?

‐ I did. ‐ Did he give you the map?

‐ I didn't get a map.

He was really adamant about no maps.

‐ Ah, crap.

‐ But you got to listen to this, man.

‐ What is this?

‐ Wow.

‐ There's 90 minutes on this tape.

‐ We've really got our work cut out for us.

If there's information about this mountain

on those tapes, I want to know about it.

We could be missing something that's really crucial.

All the answers about this mountain

could be on those tapes.

...on "Lost Gold of World War II"...

‐ John: You got all these signs and symbols

that have been leading me to this location,

saying there's something here.

It's one thing to know where something is.

Doesn't mean you can always get it out.

‐ The whole process is a huge gamble right now.

‐ It's pretty steep.

I don't know if he's gonna make it.

‐ The closer you get to the treasure,

the more careful you have to be.

‐ What is that? ‐ Is that a tooth?

‐ It felt to me like he was running for his life,

that someone could kill him.

‐ There are people that are gonna secretly observe

everything you do.

‐ All right. Good.

‐ And if and when they think you've found a treasure...

‐ You're saying he's brought you

Yamashita treasure maps?

‐ They might step in

and either steal it from you

or just kill you right then and there.

‐ What if we made our own tunnel?

‐ We found the symbol for gold.

‐ Six fingers. This has got to be the one.

‐ This is what this map is for.

‐ Look at that. ‐ It's all been sealed up.

‐ Hey, wait. ‐ Something's coming up.

‐ Is that what I think it is?
