[ Birds chirping ]

[ Snake hisses ]

Russell: We swim with piranhas.

Whoa.

We hunt boar.

Man: That's a lot of blood.

[ Animal grunting ] Shannon, hold up, hold up.

We have big cats coming near our camp.

There's something angry out there.

But it's the little things that are trying to take us out.

Oh! Crap!

Fernando: We're being picked off one by one by this jungle.

It's like the jungle's, like, hunting us.

♪♪

Russell: The Amazon's a [bleep] devil.

Narrator: The most daunting survival challenge in the world is back.

It began on the blistering savannas of Colombia.

Yeah!

Narrator: Next came the deadly bushlands of South Africa.

- Hey! - Look out!

Now the most relentless challenge yet

takes place in one of the most remote locations on earth...

Ecuador's Amazon basin.

Sprawling 2,000 square miles across the equator,

this vast, dense rainforest

is crawling with deadly insects... [ Thunder crashes ]

- pummeled by thunderstorms... - Whoa! -Holy [bleep]

Shannon: That was [bleep]

and submerged in snake-infested water.

Here, nine hardened survivalists

are about to face the ultimate challenge...

Amber: The Amazon's very remote. People may get hurt out here,

it is one of the deadliest areas I've seen... very dangerous.

Narrator: To last 40 days and 40 nights,

all with no clothes, no food, no water, and no help...

This place is uninhabitable.

It's... it's freaking miserable.

Narrator: In the return

of the most extreme group-survival challenge

on the planet.

[ Groans ] [Bleep]

We'll spend the next hour

previewing the grueling journey

nine "naked and afraid" veterans are about to begin

and few will complete.

Woman: Holy [bleep] [Bleep] you, Amazon!

Narrator: In an exclusive sneak peek,

we'll meet the men and women who have chosen to venture

deep into the heart of the amazonian darkness

and reveal their strategies, motivations, and fears.

Lacey: I have yet to be afraid.

But tonight, I have a feeling I'm going to be very afraid.

We'll also get an inside look at life in the Amazon...

- Your butt is bad. - This is what happens

when you go try to be a survivalist in the Amazon.

- It will eat you alive. - Mm-hmm.

[ Rain falling ]

as they try to survive an environment

where weather is relentless,

insects have no mercy... [ Insects buzzing ]

and unseen threats lurk in the dark.

[ Women scream ]

And it all builds to a staggering twist...

Giovanna: What is that?

That will change the course of survival

for everyone in the challenge.

Oh, my god.

This is "naked and afraid XL."

the Ecuadorian rainforest is a vast and complex ecosystem

uniquely unfit for human survival.

Over 15 feet of annual rainfall wreaks havoc on the land,

creating an endless maze of flooded mangrove swamps,

dense with caiman, piranha, and giant anaconda.

But the jungle's most serious threats

lie in what you can't see,

from deadly microscopic bacteria

that invade the smallest open wound

to the predatory jaguars

that stalk under the cover of night.

To survive this hostile environment for 40 days

will take a level of skill and discipline few possess.

What am I doing here? This just seems insane.

40 day versus a 21 day is gonna be incredibly hard.

Just because you made it 21 days on the beach

doesn't mean you can make it 21 days in the jungle.

I am excited, but I am cautious.

Narrator: Starting in three separate environments

over a 25-square-mile area,

each team of survivalists will convene in groups of three,

where they will have to work together

to survive 40 days.

Entering the riverbanks in the southern basin

is an all-male group

that consists of Charlie, Matt, and Russell...

An experienced pack of head-strong hunters.

The trio will set up camp at Punta Araña,

an area with dense vegetation

and a river swarming with man-eating piranhas.

You know, the way I see it, like, 21 days is kind of a test

to see if you can just emotionally make it.

Yeah.

40 days... you don't have everything in line, you can die.

You know, if we make it 40 days,

we can make it, you know, 400 days.

My name is Matt. I live in Lakewood, Colorado.

I teach survival, I'm a guide,

and I also make survival products.

I've hunted a lot of things in my life.

I've hunted a lot of alligators, a lot of snakes.

And when I was in Thailand on the previous challenge,

I really felt like I was starting

to actually become kind of one with that jungle.

I see dinner.

- Oh, my god. - Ah!

I will eat pretty much any creature out here.

Matt W.: Oh, bam. We got a rat in the deadfall.

I'm just telling you right now, it's delicious.

Lindsay: I don't eat meat. Have at it.

There is pretty much no bounds to what I will eat.

Well, I'm just gonna eat the tail,

if you don't mind, then.

It's about to get ugly.

One of the biggest obstacles on the previous challenge

was the weather.

And there was days that my morale would just plummet.

[ Thunder crashes ]

Yeah. [ Sighs ]

I just... I just want it to stop.

Stop raining.

The one thing that I learned from Thailand

was if you're not winning, you keep fighting,

because there is no retreat... Hold on!

We got this.

And the only way out of it is to succeed.

I am excited as hell to get out here in this jungle.

I have dreamt about the Amazon for my entire life,

and I think there is no better place on earth

to run out here butt naked

and take on essentially everything the Amazon's got.

Charlie: This is really dense jungle.

It would be tough to be alone out here...

Especially at my age.

- How old are you? - 55.

- 55? - 55.

That is a spring chicken.

55, and I don't recuperate as quickly as I used to.

My name is Charlie. I'm from New York.

I build high-rises.
