Original subtitles

This program me contains scenes of hunting, fishing,

and the killing of animals which some viewers may find upsetting

OK. Oh, can you see it? Can you...?

Oh, it's still there.

You only have time to watch down there sideways.

Yeah.

Uh-huh.

Yeah. My eyes aren't very good, but...

Oh, yeah, yeah.

God, I'd be awful at spotting them.

How did you see that from there?

Oh, shit.

Over 50% of the world's population now live in cities.

We are the most disconnected we have ever been from the natural world.

With the rapid pace in growth in which us humans live,

it would be easy to believe that there's no area left unexplored.

But you'd be wrong.

There are still majestic pockets of land

that are truly rugged, wild and untouched.

It's just brutal.

We just haven't seen proper sunlight in, like, 21 clays.

It's so dark under the canopy.

Ancl the critical thing is we need them for the health of our planet.

I'm Lucy, and I'm an explorer.

I've been leading expeditions across the world for over a decade,

and now I'm on a mission to take you with me.

On my biggest and most dangerous adventure yet,

I'm trying to cross one of these last-remaining wildernesses

located deep in the Amazon rainforest,

a journey many think is impossible.

I want to show you the beauty...

Oh, my God, look at this...!

...the surprising...

It's magic in here. It truly is magic.

...and the downright ugly.

Oh...!

With my team, we'll seek out the weird and wonderful creatures

that call this unrelenting place home.

Ancl as we journey on foot through in ho spit able jungle,

we'll learn to work with the wild, not against it.

We're very, very far from help right now.

If something happens, we are on our own.

We just got attacked by the really big wasps.

Because it has never been more important for us

to build up our relationship with the natural world...

...and protect these last wildernesses at all costs.

This is the hardest thing I have ever clone.

Guyana.

It borders Venezuela, Brazil, and Suriname,

and is the only English-speaking country in South America.

With a population of just 800,000,

most living by the coast,

it's one of the most sparsely populated countries in the world.

Guyana gets less tourists in a year

than Machu Picchu gets in a single clay,

so it's easy to see why this rainforest

is so impenetrable and unexplored.

For this adventure, I've teamed up with a group of guys

who I've known from my previous visits to Guyana.

They're all Amerindian, are all up for a challenge,

and all know the importance of protecting this forest.

We'll be attempting to cross, on foot,

almost the entire width of the country,

a journey that's never been clone before.

We are heading to King William's Falls,

and it's a journey that's going to take us, on this motorboat,

you know, a couple of clays.

Ancl then, from there, we're going to head west on foot

across the Kanuku Mountains.

And we don't know what's out there, but what we do know...

"certainly, it's going to be a big adventure.

The majority of Guyana is covered with a green blanket of trees,

and we'll be attempting to trek, climb, wade and crawl

our way through a lot of them.

We'll start on the eastern side of the country, moving west.

Ancl for the first leg, we'll be in the lowlands

and expect to be in thick forest and swamps.

At the first major river, we'll have to find our first resupply,

barrels left at specific coordinates.

From here, we'll have to find a way to cross the river

and begin the next leg.

The GPS device is unlikely to work here,

which means rescue could be weeks away.

Ancl if we're successful with leg two,

we'll reach a second river and another resupply.

Ancl after crossing the wide and caiman-infested Rupununi River,

we'll be into the Kanuku Mountains, a protected area.

This final leg will push us to our limit.

We'll be at our weakest here as we try to cross the mountains.

And so, if we can make it past all that,

we'll finish at the savannah, the border of Brazil.

We've no idea how long this might take,

or if it's even possible.

Helping set up the resupplies and joining us for the boat ride

is my good friend and jungle expert, Anders.

Well, the expedition that Lucy and the crew is about to start on

is-is-is absolutely insane, to be truly honest.

It's going to be 45 days, at least.

They're going to be covering some of the least-explored places

on the surface of the planet.

Lucy is probably the only person I would trust

doing an expedition like this.

It doesn't matter how strong you are,

you need to be able to endure this extensive stress

on your physique and your mental state as well.

And, at the same time, you need to be overseeing your team out there,

and you need to wake up,

and even though a day is looking terrible and it's raining

and you've got blisters and you're bitten everywhere,

you still have to pack up, carry on, and continue until the ultimate goal

of reaching the most western point of the Kanuku Mountains.

And I think that makes it one hell of an amazing journey

that very few could achieve.

But as well, like, very few of us could only dream of.

We've only been going for a few hours,

but already the jungle is throwing up its first surprise.

Rivers like this pose a big risk.

Tonnes of water is not to be messed with.

MAN: No, no, we're done. We're clone.

I cannot tell you how happy I am to hear that.

I am HAPPY-

Yeah, we...

We can stop before. You guys are amazing.

Now we just need to get the last boat up here.

Just when you think you're clear of trouble

is exactly the point you should never assume you're out of danger,

especially when the local wildlife is waiting.

It wouldn't be fun to capsize here.

Something doesn't feel right.

Come on.

So, we've just capsized, and we lost stuff.

Try and keep out, cos we lost a lot of important things.

Oh...!

You've seen that happen? Yeah.

It's good that no-one's hurt,

but let's just see how the equipment has fared.

WOW!

If ever there was a time to smoke a cigarette, Anders.

I'm going to have two!

Mikey, how are you? Are you all right?

I think this stayed dry.

A brand-new jumper.

Oh, my God...!

It's nearly dry.

I'm putting up my washing.

I'm washing documents, release forms here.

Nice.

You're OK, Michael, right?

None of the other guys hurt themselves, did they?

Yeah!

Wow, that could have gone horribly wrong.

I don't even want to think about it. What a way to start an expedition.

Ancl we did lose one thing. Really important that we...

You know, it's gone, and that's the water filter.

So that means, for however many weeks, months even,

however long this is going to take,

we are not going to be able to have fresh water or clean, safe water,

we're going to have to just drink it.

We don't really have a choice. There's no way we can get one.

Erm, we'll boil it as much as we can, but...

...yeah, I hope we don't get sick.

Just making our first camp, and there are red ants everywhere.

Lionel and I have been bitten alive.

So a little bit of Vaseline onto the threads,

so we don't have a little ant army coming to visit me,

or not visit, attack, in the night.

Cos they're already in my hair. I need to jump in the water.

Welcome to the jungle!

The rainforest in Guyana spans three quarters of its landmass,

which makes it home to some of the highest levels

of biodiversity in the world.

But like so many wild places, its future is uncertain.

What is certain, though, is the amount of predators

that call this place home.

The rivers are infested with black caiman

growing up to whopping lengths of 16 foot.

But if they don't get you, the anacondas and piranhas will.

On land, you've got the big cats, the sharp-toothed jaguars and pumas.

Ancl then there's the peccaries,

wild boar that charge through the jungle in packs of up to 500.

But, of all of these creatures,

there's one that my team fear the most.

Bushmaster snakes.

They are very aggressive snakes.

They're venomous. They're beautiful, beautiful creatures.

But one bite and you're a goner.

Ancl they're so invisible.

Ancl these things are sort of 12 foot long.

They're huge, but they're camouflaged.

They travel in pairs.

They have this whistle,

this whistle of the bushmaster snake,

and if you hear, it'll haunt you.

Ancl the guys have already told me that, if they come across one,

they would kill it.

I'm very much in their world here,

and I hope that we don't come across too many,

cos, yeah, they are aggressive, aggressive snakes.

It's time.

Today's the clay you leave us.

Yes, it is.

I'm going to be out there checking your every movement.

Tracking us. Yeah.

Making sure we're not slacking.

So, guys, we have been training, we have been preparing.

And this is it, right?

I want to wish you all the best.

You guys know exactly what you're doing,

so, I'm not afraid of anything.

But I will still be bold enough to ask you

to take a little care out there, take your time, enjoy the jungle.

Take care, hey?

Lionel. Yeah, man.

Fucking hell, pleasure to have you on the team, right?

Take care, Lucy. Bye-bye. See you soon.

Yeah, definitely.

Here goes the jungle commanders, ready to move into the unknown.

Yeah!

Phew, that's a pack.

This, is it.

Into the jungle we go.

The problem with moving through deep jungle like this

is you never know what's ahead.

And, at times, we might find we can walk half a K an hour,

which is actually a good pace.

Then, at other times, it could be one kilometre in a single clay.

We've found a short cut.

This unspoilt wilderness isn't just nice to look at,

it's crucial for maintaining global ecological balance

and preserving genetic diversity.

Ancl what makes this jungle even more special

is it's home to some species that are found nowhere else on Earth.

It really is an area filled with the untamed.

But that also means a lot of these creatures are ones to look out for.

Bullet ant nest.

They have been known to take down the strongest of men.

You thought you'd seen a spider's nest before?

You ain't seen nothing until you've seen this.

Whoa. They're attacking it.

Goliath bird eater.

Ancl what happens if it...?

Just hurts if their fangs get you? Yeah.

It just hurts. It doesn't kill you.

But they have big fangs. Yeah, they do have big fangs.

They are the biggest spider in the world.

One of your pets.

This spider hunts birds.

Ancl then we spot this, a tarantula hawk wasp.

This wasp hunts the spiders.

You don't want to mess with that wasp.

I'm never going to complain about the UK wasps again.

No.

Whilst we want to make good progress,

it's essential we always remain alert.

All of our senses have to be on the lookout at all times.

That's why it's vital to have a great team.

So we've got Vivian.

Vivian is head line cutter and lead snake eyes,

looking out for the deadly snakes ahead.

Vivian is so strong, and the kindest guy you'll ever meet.

Then we've got Lionel.

Lionel and I go way back. I met him in 2014,

and we've remained friends ever since.

His knowledge of the jungle is incredible.

Lionel will be cat eyes,

on the watch for any big cats around us.

Then we've got Mikey.

Mikey is the youngest on the team,

and he'll be assisting me with the filming.

And Aaron.

Aaron's a good friend and great to have around,

and his role will be lead fisherman.

Ancl my role? I'm responsible for the navigation

and making sure that we're all as safe as we can be.

We've only managed three kilometres today

and it's tempting to want to press on,

but, in the jungle, there are hard-and-fast rules

you must never break.

Number one, by 3:00pm, the wildlife come out.

Ancl I'm not even kidding. It's like they have a clock on them.

3:00pm, and you have to start getting your camp ready,

you have to be by some sort of water source.

Whatever that water might look like,

you need to be setting your fire up, eating your dinner.

And then, you know, by the time 5:00pm, 6:00pm hits,

you need to be getting your feet off the floor

and away from anything, like bushmasters and big cats.

Number two is always travel in a line.

The first person, if they spot a snake, they can tell you,

if there's wasps, you can run the other way.

A line is also there so that I can,

me being the navigator with the compass,

make sure people are on the right track, on the bearing.

Number three, you must never shout.

This is because you'll upset the Bush Dai-Dai.

The Bush Dai-Dai is this spirit.

Well, it's a mythological creature

that is very much believed by Amerindians.

Ancl it's sort of half animal, half human,

a sort of yeti-like creature a lot of the time,

bigger than a human, though,

and it's sort of like the guardian of the forest.

Ancl you do those three rules,

and hopefully the jungle will be kind to you.

So it's ten to three, and we've just made it to a little water source.

Erm...

Oh, good. Good to be at our first camp.

Firewood comes in the form of standing deadwood,

and that means chopping it down.

So, the problem with doing these things is, where we want to camp,

the wildlife want to come and hang out for the night.

There's just no getting around it, everyone wants water.

Some fire.

Fire, firelighter.

In our bags, we've got tarps, we have hammocks,

we have a medical kit.

Ancl then we have a lot of filming kit.

But the other thing we carry as much as possible as we can

is noodles and farina.

Erm, and the farina is the local food.

It's the best field food I've ever had because,

as soon as you add water, it just expands like nothing else,

so it fills you up.

It's made from cassava, and we're just adding it to everything.

We're adding it to noodles, we're adding it to our oats for porridge.

Ancl when we catch fish, we can add it to that as well.

But it is the best, the best thing to make you feel satisfied

after a long clay on the hill.

WHISTLING

Already the sound of bushmasters.

So, it's clay one. We're in our camp.

We've already heard the bushmasters.

Shows we're already in the wild, so we don't need to go far for that.

But, yeah, I'm looking forward to tomorrow

and gradually seeing us move across that map,

albeit slowly.

I've got the fire going, I'm up above the ground,

and, er, we can start the night.

WHISTLING

We're trying to sleep, but the bushmasters are getting closer.

I want us all to keep our feet above the ground,

but the guys have other ideas.

WHISTLING

We're surrounded, and it's terrifying.

We try to locate them,

but can't go too far without getting into more danger.

WHISTLING

There's no choice but to roll over and hope a bushmaster

doesn't slither underneath any of our hammocks during the night.

That was a bad night's sleep, but no-one was bitten.

Ancl another reminder that nothing here can be taken for granted.

So, this morning we realised that

we didn't actually cover much ground yesterday,

and that was a little bit worrying

that this expedition might take much longer than we thought.

Bushmasters last night, but they're not going to stop us.

Atchoo! Bless you.

Atchoo! Bless you.

We're really in no-man's land here, and a long way from help.

So, I had forgotten that walking through this jungle

is like walking through a compost bin.

The forest needs to be in a constant state of decay,

it's what keeps the soil rich in nutrients

and the overall forest healthy.

BIRDS WHISTLE AND CHIRP

The birds, they're called piha.

When they're chirping and happy like this,

it usually means that there's going to be rain on the way.

So we'll probably be expecting a bit of rain as we walk.

WHISTLING AND CHIRPING

They're very happy-

Well, the pihas were right, it is...

It's raining.

Makes a nice change from being wet from sweat.

Because of the rain, it now smells more like a compost bin.

Woohoo.

I knew it wouldn't be long before Aaron was bringing out the rum.

Yes. yes!

Mikey was about to duck under this little tree,

and, yeah, there's a snake.

So it's our first snake of the trip that we're seeing.

Luckily, this is just a vine snake, not deadly to humans,

but a little reminder that snakes really can be anywhere here.

We have to keep alert.

The terrain has changed and we're moving faster today,

but what's good for us is also a good area for wildlife.

So the guys have noticed evidence of a jaguar,

who's been around here recently.

Generally, they're OK if you're in a big group.

But if you stray, get behind, or if you crouch,

say, for example, you're getting water or going to the loo,

that's when they might get you.

Or, if they're going senile,

they've been known to just go for you.

So...

...these big cats are not something to mess with.

I can definitely see why big cats like this area because,

I'll be honest, I like moving through this area as well.

Oh, last night I kept hearing the sound of, like, footprints,

what you could imagine, like, a cat paw to be going on the leaves.

Sol kept shining my torch out into the forest.

They're always watching.

We might not know it, but they know we're here.

Rainforests not only produce oxygen,

allowing for every living being to breathe in clean air,

they are also the solution to our biggest problem.

They literally take in carbon dioxide,

and, by doing so, regulate the Earth's climate,

the very thing we are building man-made machines to do.

The answer is right in front of us, ancient forests like this one

that have been doing it for millions and millions of years.

It's never been more important to preserve them.

The jungle is the place to look if you want to, like,

spark up that childlike curiosity again.

Everything here is just incredible,

despite it being, like, a lot of things, like, very deadly.

Ancl the jungle really does sometimes feel like

everything just wants to kill you.

But once you start sort of getting into the way of things,

getting into the swing of things, it sort of becomes manageable.

And, of course, as soon as you relax,

then something else that you hadn't heard of,

something else as deadly that you're about to stand on or touch.

Ancl this is pristine rainforest that you don't want to mess with.

Ancl we have to keep it that way. There's so few ancient forests now.

We're cutting them down at crazy rates.

Look at how much biodiversity and how much life,

and these are the lungs of the planet.

And, yeah, it's magic in here. It truly is magic.

We're behind schedule.

Two weeks in, and with only 40 kilometres covered,

our rations are running low.

Our first resupply is another 50 kilometres away,

but what stands between us and that is thick and unpredictable jungle.

Good morning, Vivian. Good morning, Lucy.

It's so wet out here, they're just...

They very easily get manky and rot.

Ancl they will eventually.

But it's just a case of trying to stop them rotting as fast.

Wild places are not uniform,

but instead are magnificently unpredictable.

But that also means we faced a gruelling start

and haven't progressed as much as I would have liked.

Already I sense some of the guys might be having second thoughts.

Come on, guys, happy. Yeah.

We are happy-

So, in all honesty, the team's working really well,

but I'm a little, a little bit worried about Aaron.

He's just not his usual happy self in the clay,

and I can tell that he's finding the whole thing a little bit daunting.

So I've just got to monitor him.

If we need to, like, get him out, we'll have to figure something out.

Vivian is an absolute trooper,

he's been cutting the line every clay since we got here.

He is a strong, strong, strong guy.

We're not even in the Kanuku Mountains yet.

We have got such a long way to go.

The team's lack of fresh food is causing spirits to drop a little.

Napoleon famously once said that an army marches on its stomach,

and we need more than noodles to keep this one up.

Monkey pot. Can you eat it?

Oh, you can't eat it. It looks like a fried egg.

It looks tasty.

Give it...

Give it a few more weeks and I might eat it.

We'll see if it's poisonous or not.

The guys are always showing me the secret wonders of the forest,

including things to eat,

and they take fresh food to a whole other level.

This nut, on the other hand, has a little gooey goodie inside of it.

A kukrit grub.

Cheers.

Cookies? Yeah.

It doesn't taste like cookies.

Oh, when you toast it? Yeah, when you toast it.

It does taste better.

Still, definitely not cookies.

Whoa, today was the hardest day so far, I would say.

Yeah, we struggled to find water at the end of the clay.

We just went a bit longer than normal.

Ancl we are camped next to a sort of vaguely running little creek.

That looks really idyllic, right?

But our bathing system is not.

SHE CHUCKLES

We bathe in the puddles, in the muddy puddles.

LAUGHTER

Urghg

Slow terrain today.

This is the worst place.

Bush cow flies. It's horrible.

They've been following us all morning.

The first time I've seen proper blue sky in ages.

It's nice.

It reminds you that not everything is in the shadows.

Urgh, I'll tell you what are in the shadows,

these bush cow flies.

Yes.

Oh, you've got bush flies on your bum.

This is not easy.

Ow! I just got bit on the bum.

We're in thick bamboo bush, so we're just...

Well, the guys are clearing a space

so we can put the drone up and see what's beyond,

cos this is just ridiculous, this bush.

Yeah, today was hard.

Urgh, we only covered, like, two kilometres in the whole clay.

Large, thick bush.

If it carries on like this we're not going to make it.

Like, we'll just...

You know, our bodies will rot before we can get to the end,

cos we're not seeing any good rivers to wash in.

Like, we're not...

It's way harder than anyone ever thought it would be.

Ancl you can't see what it's going to be like on the map.

Yeah, OK.

A hard clay.

But we're going to have to, yeah...

...see what tomorrow brings.

It is relentless. It is...

...so hard.

Yesterday, I really struggled.

Everyone struggled.

Oh, my gosh, when the bush is thick...

...it's...

You just feel like you've got so much ahead of you,

and that what we've taken on is just too much.

I have to say, as much as I wash,

I wash and I wash...

... still absolutely reek.

Ancl there's no getting around it.

It's...

It's a smelly business.

We've actually found a spot that we can actually swim in,

so we can actually get a good wash, or rinse, as we like to call it,

it's not really washing.

But...

Oh, my God, look at this.

This is something special.

We may be the first humans who have ever bathed in this.

We're certainly not the first living things.

I'm sure there's going to be a lot of visitors during the night.

But, wow, what a place to end a good clay.

THUNDER RUMBLES

This is the first time we can really get clean.

Every clay we've been covered in tree dust, mud, ants, and ticks.

We've been craving to fully submerge in water like this.

Swimming in the tropical rainforest storm

while there's thunder and lightning above.

THUNDER RUMBLES

Ancl just when we're winding down...

...Aaron has fresh food on his mind.

Oh, yeah, quick, quick, quick.

This is the traditional Amerindian way of fishing,

and the guys are masters at it.

Dinner is served.

That is big.

Ancl how long do you think that will feed us for?

LAUGHTER

Whoa, that could give you a bite, right?

But Aaron's not clone yet, and catches an electric eel.

This is an electric eel.

Electric eel. Whoa!

Be careful.

It went through the wet wood? Yes.

LAUGHTER

I tell you it's going to shock you. Yes.

But you got an aimara.

So far we've been going 17 clays,

covering only 45 kilometres through this totally unforgiving wilderness.

But no matter how tough it gets,

I've never lost sight of the importance of this habitat.

The Amazon rainforest is made up of a whole interconnected web of life.

Every creature has a role to play.

Take, for example, the humble termite.

Its job is to clean up the forest floor,

breaking down organic matter

to create a habitat for other organisms,

recycling the nutrients as it goes.

But it's not just the small critters that play a part.

Jaguars are key in maintaining biodiversity

by preventing one species from dominating the ecosystem.

One of the jaguar's main food sources is peccary.

Peccary are a wild pig.

In this wilderness, it's the white-tipped peccary that roam,

and they travel in herds of up to 500

and can become very defensive.

You don't want to come across them.

Pecca ry.

HIGH-PITCHED GRUNTING

How many?

A lot of peccaries.

So, peccaries are super dangerous.

They take out anything in their path.

Ancl we have to climb a tree if they come.

They're only a couple of hundred metres away.

There's a lot of them.

They came through here. Whoa...

This is what I mean when they take out everything in their path.

Look at that.

That was close.

Our peccary encounter was a little too close for comfort.

But, for dinner, we've got our left over

and slightly questionable fish.

We're willing to take the risk

because hunger is really taking over.

We try to enjoy it as the light fades.

But then, like clockwork,

we hear that familiar whistle once again.

WHISTLING

So many here, aren't there? Yes.

WHISTLING

You can't help but think the snakes are communicating with one another,

guarding their territory, warning us from continuing on.

WHISTLING

Oh, I'm feeling pretty ropey this morning.

ROpéy, FOPGY, TO

just starting the clay wearing Croce...

...because it's too early to get our boots,

and our socks and our feet are soaking wet.

At this point, it's hard to tell whether we're feeling ropey

because of the 90% humidity, the unfiltered water,

or maybe it's the old fish.

Either way, it's taking a toll on our bodies,

and our feet are suffering being this wet all of the time.

It's just brutal out here. It really destroys everything.

It destroys your body. It destroys your kit.

It destroys your mind.

Oooh, la-la, be careful.

Erm, you need to get some foot spray.

All of this here. Yeah, that's not good.

All this here, and all of that.

Yeah, you're getting a bit of trench foot there, I think.

Go on, then, let's see the other one.

Oh, nice, nice, nice, nice.

Aaron's fixing his boots.

They're going through...

...going through hell.

Today was hard trying to stay positive.

But, you know, there's so much ahead.

I think some of the guys are showing signs of wanting to leave

as soon as we reach resupply one. I don't know.

Although Vivian is really up for it.

So, yeah, we're forming a really good bond.

Yeah, what a clay. This place is not easy.

It's raining again. Our energy is really dropping.

Our feet are really mouldy.

We are doing all the right things. Like, we are doing it to the book,

how you're meant to do it in the jungle,

but you just can't avoid your feet rotting

when you don't have any rest clays or any sunlight.

Trying to keep everyone's spirits up is harder than it seems.

It's been three weeks

of continuously moving through the lowlands,

but we've clone it and reached our first major river

and the coordinates for our resupply.

HE BLOWS A DEEP CONTINUOUS NOTE

We've got more noodles.

Sardines!

Yeah, sardines!

Oh, it feels really good.

I'm hoping that the next leg

isn't going to be as soul-destroying as this one has been.

It's pushed us.

We are going to try and make a raft out of bamboo

and also the barrels that were left that had our resupply rations in.

It's going to save us quite a lot of Ks, quite a few clays,

which we need to do because we're behind schedule.

So we're going to go and find some bamboo now.

Like everything in the jungle, bamboo has a defence mechanism...

...these lethal spikes.

We're cutting the final cane, but then...

...disaster strikes.

One falls right on to Vivian.

It might not look like much, but a spike's penetrated deep into his arm

on to a nerve.

I can't get it out, ancl Vivian's hand is paralysed.

I need to cut him up, but then we really risk infection.

Sepsis is a real threat here.

He needs to get help, and quickly.

I've sent an SOS for Vivian,

but whilst we wait, another fear sets in.

I'm worried that some of the team will see the boat

and want to flee themselves, because, really,

there's nothing stopping them from quitting when that arrives.

So I'm trying to keep up the excitement

of our imminent raft journey because, once we set sail,

they'll have no choice but to stay.

Hello, guys.

Go and get fixed up.

Come back.

We'll see you in a couple of clays. Yeah.

Yeah, you, too.

Yeah, I know. I've got to defend myself now.

Yeah.

Just remember to come back.

No!

You don't want to spend eight hours in a boat.

So while we wait for Vivian to return...

...we wait.

The guys fish.

Ancl we wait some more.

Yeah.

What's that one?

Oh, that's the black piranha?

Oh, hello!

This is one of the last remaining pristine wildernesses,

and the fish here are much better.

But the global water cycle means that, even here,

where there's almost no human activity,

the fish will still have a level of contamination.

So we've just heard from Anders that the medical people, or someone,

tried to get the bamboo out of Vivian's arm, but couldn't.

But that means they've cut him up a lot,

and he can't come back, at least for now.

Which means we need to get another person, which is a big shake-up.

It kind of sucks. Right, Mikey?

He was a bit like my...

Oooh, no.

Yeah.

I felt like he was a little bit like my good-luck charm.

So the fact that he's gone, it's kind of worrying.

It's silly, I know.

There'll be other good people, but...

...he was, like...

...he was the strongest team member.

So the fact he's gone is kind of a blow.

A new team member arrives.

Nice to meet you.

I hope Anders said that there was going to be a camera.

It's time to put the raft through the ultimate test.

These guys, you're amazing at building this thing.

The mountains throw everything at us.

It's hard.

I learn what it means to get up close and personal with a caiman.

This is absolutely mental. This is the real deal.

Whoa...!

Things don't go to plan.

We just got attacked by the really big wasps.

Ancl after months of hearing them,

we get face to face with the dreaded bushmaster.

Bloody hell!
