The Curse of Oak Island

Tonight on The Curse of Oak Island...

Time to drain the swamp.

Do it.

The swamp holds secrets to the mystery.

-Oh, ho, ho! Look. -Oh.

That's interesting.

-What do you got? -Holy crap.

It seems like jewelry.

A symbol found on Templar churches

pointing directly to Oak Island and is believed to represent

-the Holy Grail. -Oh.

If there's gold in that void,

that'd be huge.

There's something there.

There is an island in the North Atlantic

where people have been looking for

an incredible treasure for more than 200 years.

So far, they have found a stone slab

with strange symbols carved into it,

man-made workings that date to medieval times,

and a lead cross whose origin may be connected

to the Knights Templar.

To date, six men have died

trying to solve the mystery.

And according to legend, one more will have to die

before the treasure can be found.

-Hey, Roger. -How's it going, guys?

What have you got for us today?

Ah. The guys are down there right now.

So we identified a water source. It looks like it's

-confined to one space. -Okay.

An especially anxious morning

has begun on Oak Island

for brothers Rick and Marty Lagina and their team

as they work to solve a 229-year-old mystery.

So quite a bit of water.

We're looking at about 250 gallons a minute,

and I think that's our biggest problem down there.

Right.

-We want to look. -Absolutely.

That's-- Absolutely.

-I'm ready. -Sounds good.

-Let's go. -All right.

In the Money Pit area,

representatives from Dumas Contracting Limited

believe they have finally identified the location

where a mysterious inflow of water

has been flooding the 87-foot-deep

mid-18th-century Garden Shaft for nearly two weeks.

What remains unknown is if it may be related

to a legendary man-made flood tunnel

that was reportedly triggered during an excavation

of the original Money Pit back in 1804,

and which has thwarted the efforts

of treasure hunters ever since.

A long, bloody way down.

-Yeah. -You know?

Now, Rick and Marty are descending

the Garden Shaft themselves to inspect the cavern

and the mysterious inflow of water

in order to help Dumas

not only identify what each feature may be,

but also decide how to achieve

their ultimate goal of extending the Garden Shaft

down to a depth of some 95 feet,

where they hope to breach a seven-foot-high tunnel.

A tunnel which runs westward towards an area known

as the Baby Blob, where high traces of gold,

silver and other metals have been detected

between 80 and 120 feet deep.

Okay, here we be.

Do you think it is all right here?

Without all this water coming in.

Yeah.

Now that the team from Dumas Contracting Limited has

identified the source of the water,

over the coming days, they will attempt to seal it

using an industrial-grade compound known as multiurethane

that expands when wet.

In there, there's a,

it's like a little cavern.

One week ago,

while Dumas was searching

for the water source at a depth of nearly 65 feet,

their team also discovered a strange cavity

just outside the shaft containing wooden timbers

and in the same general area where, last year,

a sample of wood from the Garden Shaft

was found to contain high trace evidence of gold.

I think that we were all quite interested

in what this cavity void represents.

We have spent a lot of time

to try to follow the gold and the silver.

If there's gold in that void, that'd be huge.

That cavity might prove to be very interesting.

What about the wood that we heard was in there?

Some of it's still there, and some of it's

at the bottom of the void, I guess.

Oh, yeah, I do see it.

How far in is it?

Uh, here, take a look.

Just looks like a little grotto.

Right about three feet back there?

Four feet, maybe?

Yeah. It goes back and up.

There's a board right there.

You got it.

Come here, you.

What's that, then?

That's from the original shaft.

I don't see enough wood

to represent some other construct.

I think, at this point, it's probably associated

with the original shaft construct.

There are some pieces of wood in there.

They don't look ancient to me.

I think whoever dug the original Garden Shaft,

as they were going down,

might have needed a little bit of work room.

That's what I think we're looking at.

So, more importantly, we have metals in the water

by the Garden Shaft.

And the metals are inclusive of gold and silver.

So the next thing that has to be done in the Garden Shaft is

we have to get control of this water.

Okay. We've sort of got two issues going here, right?

-We've got this water... -Yeah.

...and then we've got this issue over here,

but we know on the outside of the Old Shaft,

-we found traces of gold. -Okay.

Yeah. We've got some good samples here.

We've got a piece of wood from the cavity.

Our job here is done.

As representatives from Dumas continue their work

in the Garden Shaft...

...later that morning...

Billy!

-I was hoping you'd leave some work for us.

...Rick and Marty join Billy Gerhardt

on the south shore road

bordering the triangle-shaped swamp.

It's that time of year again, isn't it?

-Time to drain the swamp. -Yeah.

Having just acquired a government permit,

the team is ready to drain

the brackish water from the swamp

to search for clues that may be critical

to solving the Oak Island mystery.

So, what's the plan, Rick?

You know, I-- I avoid all things swamp.

Well, I think the swamp holds secrets and I--

but I don't know where they are, to be honest with you.

Yeah, I think I'm more excited about the swamp

probably than I have been to date.

-Really? -Yeah.

Because we have the ship's rail,

you know, we got the road, we got the path, a ton of stuff,

and we've-we've only done one of the three sides.

Yeah.

In addition to ancient coins,

ship pieces and fragments of cargo barrels,

in recent years, Rick, Marty and the team have uncovered

a number of stone structures such as a road, or ship's wharf,

near the south shore road.

I'm most interested in what lies at the end of the stone road.

If it's a slipway, that's important.

If it's a wharf, it's important.

So, if I started anywhere, it would be--

-The stone road. -The stone road.

Mm-hmm.

Once the area is drained,

Billy will help the team excavate the south shore road

in the hopes of finding definitive answers

of who built the massive stone feature

and if any evidence of valuables remains hidden nearby.

When're you going to start that bad boy up?

Well, I think I did lots of times,

so one of you guys should have the honor.

-So... -Big brother? -Let's get going.

In accordance with environmental regulations,

rather than pumping the water into the ocean,

it will be diverted several hundred yards away

to the center of the island.

-Time to drain the swamp. -Let's do it. Do it.

Drain the swamp!

As the swamp begins to drain,

on Lot 5, located on the western side of the island...

-I just want to get this level done. -Okay.

...Alex Lagina and members of the team are

carefully excavating a circular stone feature

that has been determined to set atop

a much larger foundation.

Oh.

Huh? That's cool.

That's really cool.

It's a little, tiny ring.

Wow.

Hey, guys, do you want to come take a look at this?

Sure.

-Sure. -It seems like jewelry,
