[Phil] I heard that splash.
Did you see something
over there?

[Josh] On this episode
of Expedition X...

-Something's swimming there.
-[Heather] Look, there.

[Phil] I got it.
Going straight at it.

[Josh] ...we're joined by
special guest, Rhys Darby...

I didn't think I would
ever see some evidence

that made me think
it actually is real.

[Josh] ...to investigate
the world's
most-famous cryptid.

As Heather and Phil
dive deep on the tail
of the Loch Ness monster...

-What's that? Yeah.
That is big.
-Ooh.

[Josh] ...with shocking
new evidence.

Is the most iconic monster
of them all
about to be discovered?

[Phil] Oh, wow.

[Heather] Phil, you okay?

[Phil] I think I saw something
out of the corner of my eye
and it wasn't small.

-[vibration noise on radio]
-[bleep]

[Phil] Oh, my God.

[Josh] Okay, I'm gonna skip
the usual game

where I make you guess
what we're investigating.
I am too excited.

We are going after
the Loch Ness monster.

-Nessie?
-No way.

-[Josh] Yes.
-Are you serious?

Wait a second. Why now?
Did you run out of scotch?

I am absolutely serious.

And don't even joke
about running out of booze.

And the reason we are
investigating this now

is that maybe the most
compelling piece of evidence

of Nessie's existence
just came to light.
Look at this.

This is a sequence
of more than 70 photos

that were snapped at the loch
by an amateur photographer,

and they clearly show
what look like
these dark humps

coming to the surface
and then submerging again.
Look at this!

-[Heather] Am I looking
at Nessie?
-[Josh] You might be.

[Josh] Phil, you tell me.
What is this?

[Phil] I mean, I would love
to be able to debunk
that right now

but I I don't know.

The way it undulates,
it could be.

There's humps clearly
coming out of the water.

[Josh] Absolutely.

[Phil] Wow.
And it's moving quick.

There is something there,
and there is more, much more.

This is just the latest piece
of evidence

in a century-long search
for this monster

that has been equal parts
compelling and controversial.

The first recorded sighting
of a monstrous creature

in Scotland's river Ness
dates back to 565 BC,

when St. Columba,
an Irish missionary,

was said to have
stopped the beast
from attacking a swimmer...

...banishing it downriver
to the loch
by the power of God.

Local folklore kept the legend
of the monster alive
for centuries

until documented reports
began regularly emerging
in the 1800s,

including a diver in 1880,
who claimed to see a creature

resembling a huge frog
staring up at him
from the lochs deepest depths.

Perched on the edge
of the wilderness
in the Scottish Highlands,

the 23-mile-long,
750-foot-deep Loch Ness

remained hard to access
until 1933,

when a major road was created
along its north shore.

As soon as the road opened,
sightings began to pour in.

In 1933, a hotel worker
and her husband

reported seeing
a huge black whale-like beast

rolling and plunging
on the surface of the loch,

creating waves big enough
to be caused by a steamship.

In April 1934,

a photograph was taken
that instantly
catapulted Nessie

to become the world's
most iconic cryptid.

The so-called surgeon's photo
seemingly shows

a long-necked monster
prowling the loch.

And while the photo was
later debunked as a hoax,

it did nothing
to diminish the belief

that Nessie was perhaps
a dinosaur that had somehow
survived extinction,

a plesiosaur, to be exact.

After decades
of further sightings,

in 1962, the Loch Ness
Phenomena Investigation Bureau

was founded
by the UK government

to collect scientific data
and footage of the monster.

It disbanded 10 years later
with no conclusive proof

for or against
Nessie's existence.

But evidence
continues to emerge
right up to the present day.

In 2020,
a fishing boat's sonar

registered a 33-foot-long
mysterious shape
557 feet down.

And now comes
what is potentially

the most extraordinary
evidence yet,

a series of images
taken by photographer,
Chie Kelly,

which capture what seems to be
a huge creature
moving through the loch.

Remarkably, despite global
scientific scrutiny,

these photos
have not been debunked.

Is the Loch Ness monster real?

And is it finally ready
to be discovered?

And here we are with the man
who broke this evidence
to the world,

actor, comedian,
monster enthusiast.

-Yes.
-Rhys Darby.
Good to see you, man.

Thank you.
And thanks for having me.

Of course. The last time
I spoke to you,
we were in this very room...

-Mmm-hmm.
-...and I was amazed,

first of all, by your,
uh, impressions
of old creaky doors.

[mimics door creaking]

-It's staggering.
-[mimics bird cawing]

Always a bird.
There's always a bird
trapped inside.

And also, I was amazed

by your genuine passion
for cryptozoology
and for the unexplained.

-It's my thing.
-You love this stuff.

-I love it.
-When did you first
get into this kind of stuff?

-When you were a kid?
-Definitely, about
the age of eight.

Monsters, UFOs, ghosts.

What about Nessie?
When did you get into Nessie?

Every year,
the Nessie phenomenon

is the only one
out of all the cryptids,

now and again, when it's like
drying up a little bit,

there's a... [vocalizes],

and then all of a sudden
something... the ripples
come up,

and there's a great photo,
or there's a sonar,
or a radar image.

It's... What is it?
Is it an ancient dinosaur?

And it didn't make sense
that there was one

-that lived forever. [laughs]
-Right.

-That is... That is the tricky
thing about Nessie.
-We don't think about that.

-You really need Nessies.
-[Rhys] Yeah. Yes, absolutely.

-That's the $100 question.
-[Josh] Right.

-Yeah.
-And probably
a bit more than that.

-Probably worth at least
a few thousand.
-[Heather chuckles]

Thankfully, these photos
that Chie Kelly took

were high-def
and they were on sports mode.

There was a lot of them,
and then gave them
to Steve Feltham.

He's the legendary
Loch Ness hunter.

-Been there for 30 plus years.
-[Phil] Wow.

And Steve gave the footage
to my podcast,
The Cryptid Factor

because "Buttons" Kirkbeck,
who works on my team,

is an amazing video
and audio analyst.

Three days later,
after no sleep,

he came up with the results,
and we shocked the world.

How many times have you
watched this footage?

-I'm watching it
right now. Wow.
-[Phil] Yeah.

-[all laughing]
-Pause it. Oh, that is good.

-That is good.
-Yep.

I didn't think I would
ever see some evidence
that made me think,

-"Oh, gosh,
it actually is real."
-Right.

[Rhys] And this
is the first time
I've seen that.

And there's been hoaxes
and what have you.

It's hard not to look
at those images
and be drawn in...

-[Rhys] Yeah.
-...by the question
of "What if?"

-Yeah.
-Is that some unknown,
huge, unknown creature?

-Yeah.
-Yes.

-Heather says yes.
-[Rhys] Yes.

-Phil, you'll learn quickly
is our resident joy kill here.
-[Rhys] Okay.

He... he probably
is not convinced.

But even you have to admit,
those photos
are very compelling.

They're really compelling.

It does look like
a big animal in there.

But it could just be something
that we we do already know.

And there is precedent
for these large
marine species,

something like
a Greenland shark,

something like a dolphin,
something like a seal

to be able to enter a lake
and live there
for a long time.

Except what we have
in this footage,

it's indefinable.

-It feels alien
for a lack of a better word.
-[Rhys] Yes.

Honestly, I think you guys
should get out there.

Okay. I can connect you
with Steve Feltham.

You'll be the first team
to get out to the exact area
where this was taken

since the evidence dropped.

We've got something
special here and I think
you need to find it.

-It's exciting.
-This is
a bucket-list investigation.

-I mean, I can't wait
to get out there.
-Let's do it.

Well, I couldn't have said it
better myself.

You guys have
your marching orders.
Head out to Loch Ness.

See if you can separate
fact from fiction

and get to the bottom
of this new evidence.

And since you're gonna be
in Scotland, Phil,

you should probably
wear a kilt.

-I'm not doing that.
-Oh, come on.

-You ever wear a kilt?
-Oh, yeah.

-It's great, right?
It's breezy.
-I love it.

-Nothing underneath.
-Yeah.

We'll see. We'll see.

-[mimics Scottish accent]
Okay.
-[laughs]

[Josh] It's an
eight-hour flight

from New York
to Inverness, Scotland.

Then, Phil and Heather
make the 30-minute drive
along the River Ness

to Dores Beach
on the northern end
of the loch,

to meet with top Nessie
researcher, Steve Feltham.

[Phil] Okay, well, beautiful
Scottish countryside.

That is beautiful.

[Phil] But it is way more
remote out here than I thought
it was gonna be.

-Do you know what
we should do?
-What?

-We should listen
to bagpipe music.
-Oh, yeah.

-Ready?
-Ready.

-[bagpipes playing]
-Now we're talking.

-[Heather]When in Scotland...
-[Phil] Twenty-three
mile lake.

I imagine once we see it,
you can't miss it.

It is a huge lake.
It is extremely deep.

A lot of places
for things to hide.

I'm feeling lucky.

-You know what I'm feeling?
-[Heather] What?

-I'm feeling lochy.
-[laughs]

[Phil] Is that it?

-Oh, my gosh, yeah.
-The distance down there.

Yeah, yeah, yeah, yeah.

-[Phil] There it is.
-[Heather] We're here.

[Phil] Loch Ness. Ooh.

I'm guessing that guy
down at the end of the beach

with that giant
spotting binoculars,

-it's got to be Steve.
-[Heather] Definitely.

[Phil] Steve Feltham
is a Nessie researcher

who's been living
on Dores Beach,

and searching
for the Loch Ness monster
for over 30 years.

He holds
the Guinness World Record

for the longest
continuous vigil
in the search for Nessie.

Hey, Steve, I'm Phil.

Hi, Phil, nice to meet you.

-Good to meet you.
-[Heather] Heather.

-Hi there.
-Nice to meet you, Steve.

Anything out there today?

Not so far.

But you've been watching
this lake for how long now?

Thirty-three years, full time.

-Thirty-three years.
-Yeah. Mmm.

And how many times
have you seen it?

In the first year,
I saw something,

as if a torpedo shot through
the water.

Waves this high
all going that way.

So something
was just below the surface,
pushing through.

How fast?

Pretty fast.
Less than 10 seconds.

This thing just went
boff, boff, boff, boff,

as it hit each oncoming wave.

Just a white spray,

And I just froze
and pointed at it.

And then it was gone.

-So, we've seen these amazing
photographs that Chie took.
-Yeah. Yeah.

Where did she take
those pictures?

Just here on Dores Beach.

She'd been
for something to eat
with her husband

in The Dores Inn.

They came out for a walk
along the beach,

and just out here,
only 200 meters
from the shore,

she became aware
of a disturbance going on.

She had a very good camera
with her.

She set it to sports mode
so it would take a succession
of pictures.

And in total,
over three minutes
she took 71 images.

Normally, if we get
a sighting here,

people take one
or two photographs.

Historically, they're normally
grainy and out of focus,

and normally,
I can explain it.

But those, I looked at them
and I thought,

"That really does
defy explanation."

So, have people
analyzed these images

to give theories
on what else it may be?

The theory is that
it's the bubbles caused
by a couple of divers.

[Phil] Did she see any divers
active on that day?

-[Steve] Very much not.
-[Phil] No boats came by
to pick them up.

No. No.

Is there any other recent
evidence that stands out
to you?

Yeah, very much.

In fact, the piece of evidence
that eclipses this
in the quality

was taken by Ronald Mackenzie.

He drives a pleasure boat

that comes out
of Fort Augustus
on hour-long trips.

He's been doing it
for 40 years.

He's got state of the art
sonar equipment on there,

and as he turned,

it went across the middle
of Loch Ness

His sonar picked up
this single target.

-This one right here.
-That one right there.

[Phil] That is amazing.

Yeah. It's like a bathtub.

The sides com
straight down like that.

So it's totally flat-bottomed.

[Heather] The depth of water
where this anomaly
was captured

is 189 meters, or 620 feet.

Using the sonar data scale,
we can estimate
the object's depth

to be approximately
557 feet down
and 33 feet long.

[Steve] That's massive.

So that to me,
is the absolutely best piece
of evidence

I've ever seen from here
of a big animal swimming about
in these waters.

[Phil] So,
after all these years,
you do still think

there is something
big out there
waiting to be discovered.

I am absolutely
convinced, yes.

This is probably
the world's greatest mystery.

Thank you for all the
information you've given us.

We will keep our eyes
on the lake
and see what we find.

If you can find
an explanation, let me know.

Do what we can.
All right, Steve,
appreciate it.

[Heather] Now that we know
the exact location of Nessie's
most recent sighting,

Phil is heading out
to the same orange
and white buoys

we saw in Chie's photos.

Some believe
what Chie photographed

was just scuba divers
and their bubbles.

So we plan to put that theory
to the test.

While Phil dives
near the buoys,

I'll be on shore
with my camera

in the exact same location
Chie was when she
took her photos.

[Phil] Okay, Heather,
I'm at the buoy.

I'll get my dry suit on.

Let me suit up
and get in the water
and blow some bubbles.

Can't wait to see
what you see.

Okay, let's get suited up.

Okay, put away the walkie.

Once I'm in the water,
we'll switch to water comms.

-Copy?
-[Heather] Copy that.

Say hi to Nessie for me.

[Phil speaking]

Phil, how's it looking
down there?

[Phil speaking]

[Heather speaking]

Or a loch monster.

Be safe out there.

[Phil speaking]

[Heather speaking]

I mean, the spacing
is completely different here.

I'm seeing constant bubbles,

and with Chie's pictures,
there are gaps.

-[camera clicking]
-The shape also seems
very different.

This doesn't look like
Chi's pictures at all,

which is exciting because
that means we might have

real images of Nessie.

I got the shots.

[Phil speaking]

[Heather] Hey, Mr. Mermaid.

Let me see how these bubbles
turned out.

-That's the buoy.
That's your bubbles.
-[Phil] Yep.

That's my bubbles?

They're tiny. I'm sorry.

-Hold up. Let me compare
to Chie's photos.
-Yeah.

All right. So this is
what is really interesting,

and I think
you're gonna like it.

Okay.

There's her...
whatever she saw.

[Heather] Look at that.

[Phil] Come on.
Keep scrolling through.

That can't be as big
as the bubbles got.

-Really?
-I... Yes, I'm telling you.

I looked at all these images
and they're
teeny-tiny bubbles.

And that It is huge.

Let's look at the shape
of the bubbles.

Here, and then the shape
of whatever that is.

[Phil] They look
nothing alike.

[Heather] No,
and that's exciting.

It's true,
but here's my thought.

So, have you heard
of Diel Vertical Migration?

-No, Phil.
-[Phil] Okay.

So, it's this pattern
that organisms exhibit

when they're either
in marine environments
or really deep lakes,

where by day,
they stay at the bottom,

and then they do
this vertical migration.

At night, they come up
closer to the surface,

which means if there's a lot
of other animals

big and small
that exhibit this behavior,

maybe if there's something
big living in this lake,

it would do
that behavior, too.

Oh, okay. So you've already
got a plan in place?

Oh, yeah,
we're looking for Nessie.

I'm not messing around
with this investigation.

I like it.
I feel the exact same way.

[Phil] With our equipment
in tow,

we meet with local skipper,
Les Butterworth...

...and board his
31-foot fishing boat

capable of scanning
the deepest depths
of the loch.

I'm guessing you spent
a lot of time on this water.

And do you think Nessie
is out there?

Okay,.

You believe there's something
in the water.

[Phil] Mmm-hmm.

They've all seen.

I don't know about you,
but I'm eager to get out
on the water today.

Okay.

[Heather] We set off towards
the northern end
near Dores Beach.

Our plan is to divide
the loch into a grid,

methodically scanning
every stretch with the sonar.

Okay, so I've got this laptop
hooked up to the boat's
on-board sonar.

So as we travel the loch,

we will document
every single thing
underneath us.

I mean, look how deep
we are already.

[Phil] Six-hundred...
Almost 600 feet.

[Heather] So, what are
some animals that you think
might live in the loch?

-That could be
mistaken for Nessie?
-Yeah.

Well, it has been documented
that the occasional
bottlenose dolphin

or seal comes
up the River Ness

and actually gets trapped
inside the loch.

Those are easily big enough
for someone to see it quickly

and think they're
seeing Nessie.

And then there's the theory
that Nessie herself
is just a giant catfish.

This species,
called the wels catfish
can live over 100 years,

can be up to 15-feet long
and weigh 600 pounds.

I mean, I hope
it's not a catfish.

I eat way too much
fried catfish

to come all the way over
to Loch Ness
to just discover a catfish.

[Phil] Well, if we do find it,
you're not frying
this one, Heather.

[Heather] I know. I'm not.

As the hours tick by,
our search continues
into the night.

It's two hours after sunset.

We've investigated the loch
from end to end
without spotting anything.

We're now back
where we started,

at the place Chie
took her photos.

Phil tells the boat to idle.

He wants to explore
if the Diel Vertical
Migration theory,

also known as DVM,
might apply to Nessie,

seeing if we can spot it
traveling to the surface
in the early night to feed

[drone beeping]

Phil flies the thermal drone
while I use
the night-vision binoculars,

scanning the surface
of the loch
for any signs of life.

Scanning the waters.

[Heather] You're not seeing
any fish.

Nothing right now.

[Heather] And are you sure
that'll pick up over water?

[Phil] Yeah, because
if you calibrate a drone

to the temperature
of the water,

anything a little bit over
that temperature
could show up.

But I'm really not
seeing anything.

I'm gonna get
a little bit lower

to see if maybe
get better resolution.

But I'm just seeing
cold water right now.

So much for your DVM theory.

The science is sound.
It's just, uh...

It's just not
sciencing tonight.

[Phil] Yeah, I guess so.

[water splashes]

-[Heather] Oh, my God.
-[Phil] I heard that splash.

Did you see something
over there?

[Phil] Holy [bleep], Heather,
there's something in there.

-[Heather] Do you
see anything?
-[Phil] Okay, hang on

So that is on the right side
of the boat.

Bring the drone back.

Okay, I got the boat.
Right side.

I'm basically right overhead
where that splash was.

Something splashed
right there.

I've got the drone right over.

Come on.

Show yourself.

Seeing anything?

[Heather] Nothing.

I'm not seeing any big waves.

[Heather] No. No, nothing.

And we heard something.

[Phil] Yeah. Big splash.

I mean,
the one thing to consider

is they talk about the lake
as one giant bathtub

where the currents can go
from one side to another.

Possibly

what we just experienced

was energy from
one side of the lake

colliding with energy
from another side of the lake

and we got
a single giant splash.

[Heather]
But I'm not buying that

because whatever I heard

wasn't a rogue wave.

It was what caused the wave.

If so, where did it go?

A lot of hiding places
on Loch Ness.

[Phil] Yeah.

The next morning, we arranged
for a group of passionate

Nessie researchers
to meet us at a lochside pub

to see if we can get
more leads.

Well, thank you guys
for joining us.

The reason we want to
come here now is essentially

in response to Chie's photos.

Those images
that just came out

that are hard to explain.

Indeed.

We're really eager
to get more intel

on the history and some of
the recent sightings that
have been happening here.

You have essentially lived
and breathed it,

and your families have,
for generations.

Yeah, yeah, yeah, yeah.

My own personal experiences

relates to my late father,
Ian Cameron,

who had probably
one of the most

amazing sightings
of something in the loch.

What can you tell me?

[Willie] So he saw an object

rise in the water
off Urquhart Castle,

and it was rotating slowly

in the water as it was moving,

went against the headwind,
and disappeared.

But the most interesting part
of the story was

the time scale was 50 minutes.

It is regarded
as the longest sighting
on record of something.

Multiple witnesses saw this?

Nine in total that we know of.

If there were nine people
that saw something

that big in the water,

it just brings up
the question,

what was it?

So I run a group
called Loch Ness Exploration,

and we use hydrophones,

and we listen
to the loch's story.

And through that,

we're trying to figure out
what is natural

and what is man-made.

So what's the most
interesting evidence

that you've discovered?

-The most recent I got was
probably about a month ago.
-Ooh.

Um, we picked up
a very interesting,
bizarre sound.

Um, and I've
actually got audio
if you would like to hear it.

-Yeah.
-Do you have the recording?

I've got it with me, yeah.

[Alan, on recording]
That's wind turbulence

coming down
from the surrounding hills.

Hitting the loch, it's...

[eerie sound]

What was that?

I have no idea,
but it caught me off guard.

[Heather] So theories on
what it could be.

Could well be wildlife.

It could be man-made.

It could be pipes.

It could be a sudden rush
of water. We don't know.

Can I get a copy
of that recording?

I definitely want
to listen to it

-multiple times.
-Absolutely.

So obviously the loch is huge.

Where do you guys think
we should be looking?

You could check out the caves,

because that's what
we're looking at now.

Is Nessie even in Loch Ness?

Do you think there are caves

where Nessie may live?

Yeah.

What we found were these deep,
dark pools of water.

And we know
after about nine meters,

visibility goes to nothing
in Loch Ness.

And when we were
looking at them,

they were pitch black.

[Phil] On the eastern side
of the loch,

11 miles south of Dores Beach,

lies the River Foyers.

It winds up through
the Scottish Highlands,

but many believe
it connects to the loch

through secret
underground caves and tunnels.

Some theorize these caves
are where Nessie

gives birth to offspring,

and is how she's stayed hidden
for all these years.

Well, those caves
sound fascinating.

Could you get me
those coordinates?

Yeah, absolutely, guys.

I'm willing
to share that with you.

Thank you.

[Heather]
With two solid new leads,

we head back to the loch
and check in with Gates.

[in Scottish accent]

What's that? I feel like
we have a bad connection here.

I cannot understand
what you're saying.

[in normal voice] No,
I'm saying, "How's it going?"

Scotland style.

Uh, sure.

Okay. More importantly,
how's it going with you?

Well, I gotta say,
it does seem like there's

something strange
happening here in Loch Ness.

Phil tried
his scuba diving best,

but we could not debunk
Chie's photos.

Yeah, and when we were
on the boat yesterday,

I didn't see a monster,
but I heard a splash.

[Heather] Yeah, something
breached the surface,

and then there was
this loud splash.

Well, hold on a second.
What do you think this was?

Phil, you're saying
you might have

genuinely encountered Nessie
out there?

Sure, there's always a chance,

but there's also
probably a better chance

it could have been a seal

or a big salmon just flying up

and flopping down.

-A big salmon?
-Yeah.

-[Phil] Who knows?
-[Heather] Look, I'm not

the only person
that has been seeing things.

We just met
with a bunch of locals

that have their own
encounters with Nessie.

So I'd like to
follow up on some

weird sounds that
have been heard on the loch.

And I want to
check out these caves
that some people think

could be
the Loch Ness monsters'

hiding place
or even birthing pool.

Oh, baby Nessie.
How great would that be?

All right, listen, guys,
solid leads. And also,

I have just secured
something for you that could

break this case wide open.

Okay.

I got you access
to a world-class

Deep Trekker submersible.

This is one of the best

remote-controlled subs
out there.

It is capable of reaching
the bottom of this loch.

So if Nessie is down there,

this thing should find her.

That is amazing.

Nice.

Oh, and, Phil,
Heather texted me

that you refused
to wear a kilt.

Wear a kilt.

You'll love it.
It's breezy. Trust me.

I'm not wearing a kilt.

He's wearing the kilt.
I'll keep working on it.

Excellent. All right,
stay safe, guys.

Oh, my God, behind you!

[Phil] What are you seeing?

Made you look.

Oh.

That's a lesson. Never sit
with your backs to Loch Ness.

I'll see you later.

[Heather] While Phil
heads to Paige's coordinates

on the hunt for caves,

I get back out on the loch,

sailing to where Alan recorded

the weird
potential Nessie audio.

I'll use the sound itself
to see if I can perhaps

provoke whatever created it
into making another noise.

I connect our tablet
to a wireless speaker,

secure it in a dry bag
weighed down with heavy rocks,

and lower it into the loch.

Alan's weird sound
will broadcast underwater

on a continuous loop.

[audio playing on loop]

[Heather] After 20 minutes,

I retrieve it.

Can you hear us, Nessie?

We've been talking to you.

And then use the hydrophone
to listen for any response.

[Phil] As I head upstream,

the GPS coordinates
take me away from the river,

and I find myself

in the heart
of the Scottish Highlands.

So we just gained
a bit of elevation

moving away
from that river. Now,

the GPS is telling me
I've got to go back down.

There should be
a stream down there.

Oh!

Oh, I was afraid of that. Ooh!

Ooh, that is steep.

This is officially
getting interesting,

because any time
you have running water

and rocks,

you get erosion,

and you get an opportunity

for a cave to form.

So, I think we're
in the right place.

I've just got to find
a way down there and not die.

Let's move.

This is really steep
coming down.

All right. [bleep]!

[grunting]

Oh! [grunts]

[grunts softly]

I think that'll leave a mark.

Okay.

One more step.

Okay.

Woo-hoo-hoo! We made it.

Now, that

is a beautiful stream.

Oh.

Okay, okay.

Let's find those caves.

If there are caves
that connect to the loch

via underground tunnels...

Got to be here.

...this really could provide
a plausible explanation

of how Nessie
has remained hidden

for so many years.

[grunts]

Oh, yeah.

Marine animals,

including seals,
dolphins, and whales,

can use secluded
breeding pools like this

for protection.

This is so slippery here.

So I've brought with me
an eDNA kit.

This test will detect

any DNA found
in the environment,

identifying the presence
of any creatures,

known or unknown.

Oh...

my goodness.

I think we found it.

I think we found it.

That, my friends, is a cave.

I cautiously maneuver
the slippery terrain,

slowly making my way
along the river

to what looks like a cave.

This must be
what Paige was talking about.

Oh, my gosh. It's here.

That looks like a cave
beneath the water.

She's right. It's pitch black.

How deep does that go?

Little pools like this

look like they
go down forever.

But because of all the peat
in the water here,

the thing that makes the loch
so dark itself,

it's hard to tell.

But I brought
my syringes to take

an eDNA test of the water.

It's a way of
collecting water and filtering

all of the DNA
that's in that water.

The E in that
stands for environmental.

Every single known species
around here will show up

when we analyze it.

Whether it's a salmon,
whether it's an eel,

or, you know,
whether it's a Nessie.

[Heather]
After an hour and a half
of monitoring,

I hear nothing unusual.

That is, until...

[eerie sound on hydrophone]

[eerie sound continues]

Oh, my God.
What the hell was that?

After capturing
that incredible audio,

I urgently need a way
to search the area

for whatever made it.

I race back
to the dock to meet Phil...

who's now equipped
with the ROV Josh sent us.

I play the sound for him.

[eerie sound on recording]

Sounds like a whale.

What are we talking about?

But what would
a whale be doing in the loch?

[Phil] I'll admit,
that does sound

kind of like an animal
communicating underwater.

Where did you
get this recording?

A couple of miles
north of here.

I know exactly where it was.

As we go full throttle
back to where I recorded it,

we need to get the ROV
in the water fast

to see if what made that noise
is still in the area.

[Phil] Okay.

So, this is the Deep Trekker.

It is rated
up to 1,000-foot depth,

meaning we can literally

get to the bottom of the loch.

-All right. Should we
get in the water?
-[Heather] Yeah.

[Phil] Built to withstand
depths of 1,000 feet,

the Deep Trekker
is fitted with a 4K camera

and a highly sensitive
built-in imaging sonar

with a 200-meter range.

It also features
20,000-lumen floodlights

to illuminate the murky waters

of the bottom of the loch.

Deep Trekker's in the water.
We are going down.

What we can see
with our eyes here

is obviously
a little bit different

than what the sonar can see.

It's amazing that
this looks so murky,

but we're still able to get,

visually, some hits
on the sonar.

[Phil] Yeah.

Whoa, there's something.

Something's swimming there.

First eel!

Apparently, this loch
is full of eels.

Okay, back down
to the bottom here.

What's that?

You see it?

-Ooh!
-Yeah. Yeah.

Yeah. Based on the scale,

-that's huge.
-How many feet?

That is big.

Keep the depth still
so we can really look at it.

-Okay, I'm gonna go down.
-Okay.

Slight... slight right.

-[Phil] It's gone.
-It's gone.

-There was something there.
-There was.

-But we lost it.
-[Phil] No.

-No. Come on, come on.
-[Heather] We lost it.

-No, I don't see it.
-It's gotta be there.
Okay, so,

-I'm gonna go up and down
to scan the sonar...
-[exhales]

...because we're seeing far--

[exclaims]

I got it!
I'm going straight at it.

Going low, going low,
going low, going low.

Keep your eyes
glued to that sonar.

Forty meters.

[Phil] I'm steering the ROV
in the direction of it.

[Heather] 35 meters.

[Phil] This thing is huge.

[Heather] 30 meters.

[Phil] Come on,
come on, come on.

[Heather] 25 meters.

You see anything?

[Phil] Getting closer!

Fifteen meters.

-What...
-Look at it. Look, look,
look, look, look.

There's a huge cloud.

The most recognizable photo
of the Loch Ness monster

happens to be both the first

and the most controversial.

This iconic shot

was originally
published in 1934

in the Daily Mail newspaper.

For 60 years,

it stood as
the strongest evidence

that the monster was real.

Then, in 1991,

Christian Spurling,

a former employee
of the Mail back in the '30s,

admitted the shocking truth.

The photo was a hoax.

Christian explained
he created it using

a toy submarine
and forced perspective.

His monster

was actually
only 14 inches high.

In the years since,
there have been many more

Loch Ness monster photos
proven to be fake.

As any good Scotsman
will tell you,

just because some have taken
liberties at the loch,

it doesn't mean that Nessie
isn't still out there

waiting to be discovered.

[Phil] There was a huge,
huge dust cloud.

Wow. Look how still
everything is right now.

It is not moving naturally
from the water,

meaning something
must have stirred up

the bottom
of the lake right here.

And also, it's gone.

It's not on the sonar.

What would make that?

I don't know.
I mean, I guess conceivably,

it could just be a big fish

that was hunting down there
and it kicked it all up.

But the whole reason
we went here

was that strange sound
on the hydrophone.

Right in this spot.

[Phil] Look at
the depth right here.

About 15 meters.

I can dive that.

I'm gonna get my diving gear,
I'm gonna get in.

Hand over the controls to you.

-I'll gear up.
-[Heather] Okay.

Come on, Nessie.

[Phil] Okay,
I'm now descending.

Copy that. Just be careful
when you're going down.

[Phil speaking]

[laughs]

[Phil speaking]

[Heather speaking]

What are you seeing
down there?

[Phil speaking]

Copy that.
Keep your eyes peeled.

[Phil speaking]

[Heather speaking]

We're not even on
the edge of the loch.

[Phil speaking]

[Heather speaking]

Keep to the side of the trench

and don't lose
your orientation.

[Heather speaking]

[Phil speaking]

Whoa, whoa!

[Heather speaking]

Phil?

[Heather speaking]

[Phil speaking]

What do you mean, something?

[Phil speaking]

[Heather]
It's not on the sonar.

I'm not seeing anything
on the ROV either.

[Phil speaking]

[Heather speaking]

[Josh] My team
scoured the length, breadth,

and depth of Loch Ness

on the hunt
for its eponymous monster.

We came to investigate
the extraordinary photos

that Chie Kelly captured.

Fascinatingly, we were unable
to debunk them.

[Phil speaking]

[Josh] Whatever it was
she photographed,

it was certainly
something extremely unusual.

Phil was unable
to determine if there were

secret Nessie caves
along the River Foyers.

But he did take an eDNA sample

to discover what was
in its waters.

The results came back
with matches

for various fish,
including sturgeon,

trout, and lamprey.

But curiously, there was also

a match for
what was termed unexpected.

We were informed this could
just be a sampling glitch,

or it could indicate
uncatalogued DNA.

[eerie sound on hydrophone]

Oh, my God!
What the hell was that?

[Josh] We sent Heather's
hydrophone recordings

to marine biologists
for analysis.

They agreed the sound
was not man-made,

but said it was
most likely methane

released by the loch's
ancient sediments.

[Phil speaking]

[Josh] We commissioned
a sonar scan

of the so-called trench

Phil spotted
while scuba diving.

It turned out
to not be a trench at all,

but rather a typical 30-foot
underwater shelf.

[Phil] Okay.

But that's not to say
the mission was a bust.

The sonar readings
recorded from the ROV

right before that dive

proved very intriguing.

[Phil] What's that?

-Ooh.
-Yeah.

[Josh] Analyzing the raw data,

it appears the team was
chasing an aquatic creature.

And it was big,

over 20 feet long.

Perhaps it was a large
undiscovered Wels catfish,

as others have
theorized in the past.

Or could it
have been something

even more extraordinary?

The question remains,

is the Loch Ness monster real?

Our evidence
only deepens the mystery.

But I wouldn't
write Nessie off.

After all, that loch
is vast and deep.

So keep those cameras
pointed at the water.

Perhaps one day soon,

Nessie will be ready
for her close-up.

Oh, and speaking of close-ups,

we did finally get Phil
into a kilt.

[sighs] I mean...

[Josh]
Just don't look too closely.

-Feels great. Okay.
-Whoa! Too much.

-Too much.
-Forgot about the wind.

[Heather laughs]
