03x05 - Argentina Impossible

[bunniefuu]

[ thunder crashing ]

Lisa: Takes
everything out of me.

Coldest night ever.

Lisa: I don't think
I'm gonna make it.

Tom: This is -- it's for real.

Like, our lives could
seriously be in jeopardy.

Narrator: In the world's
harshest environments,

two experienced survivalists

put their skills to
the ultimate test...

[ crying ]

aah!

...Without food,
water, or clothes.

I'm really cold.

Rain's coming down like crazy.

Narrator: Now, high in
the rain-soaked cloud forest

of argentina

two strangers must work together

to survive in the
extreme cold for 21 days...

Tom: It's really just
bone chilling right now.

Hey, "naked and
afraid." it's tom mcelroy.

I -- this is my diary camera,

getting ready for
heading out to argentina.

My name's lisa coray,

and this is the
morning that I leave.

Feels like it's already
about 70 degrees

out here in california.

I have no idea

what the temperature's
gonna be in argentina.

Love the winter.

Narrator: Along the 34th
parallel in south america,

argentina's cloud-covered
mountain jungles

are being pummeled
by a massive storm front.

16 inches of rain, twice
the monthly average,

have fallen in the
last three days,

causing deadly flash floods, a
10-degree drop in temperature,

and the wettest,
coldest conditions

in "naked and afraid" history.

Fully aware of the
heightened risk,

both survivalists have agreed
to proceed with the challenge

as planned.

[ thunder rumbling ]

tom: It is raining, it's
wet, everything is soaked.

It's gonna be a long, long day.

I'm a wilderness
survival instructor.

Having taught survival
for the past 20 years,

I've got a large bag of tricks.

I've taught everything
from bows and arrows

to basket making, pottery.

Being somebody that likes
to run off into the woods

also lends itself
to being a loner.

There's definitely times I
get impatient with people.

Looking at these
conditions of cold and wet,

I'm concerned my partner's
gonna tap out in the first hour

and I'm gonna be
alone for 21 days.

All right, day 1 of the
21-day survival experience,

and it is pissing down rain.

I am a pediatrician.

I enjoy working with people,

and I have been
studying survival

for the last several years.

I love minimalist camping,

building shelters,
building fires.

I've also spent a lot of time

working in an
emergency department,

so I understand how
to get things done

when I'm under stress.

I hope that my partner
isn't a micromanager

because that's kind of
one of my pet peeves.

Here we go.

After everything I
was thinking about,

this is the worst-case
scenario I was planning for.

It's cold, it's wet,
it's pouring rain.

This is gonna be rough.

Lisa: The nakedness
-- "ooh, I'm naked,"

meeting somebody
I've never met before,"

it's gonna be odd.

I hope that my survival
partner's a nice person,

I hope that they have
a sense of humor,

and I hope that we
get along together.

All right, here we go.

Nice to meet you.

Great to meet you, too. Tom.

Lisa.

So, this is awkward, huh? Yes.

[ both laugh ] yes, it is.

Nice outfit. Thanks.

I got mine at the gap.

[ laughs ]

but anyway...

Uh, yeah.

Narrator: Lisa and tom are
allowed two basic survival items

and will be documented
by a small crew

who will only intervene in
case of a medical emergency.

I have the map.

Let's check this out.

Tom and lisa have
been dropped off

on the eastern side
of the andes mountains

at an elevation of 4,000 feet

and a temperature
of 63 degrees --

the highest and
coldest insertion point

of any previous survivalist.

Being wet and
naked at this altitude

drops core body temperature
by several degrees

and severely increases
the threat of hypothermia,

and food sources will be scarce

as animals such as wild
turkeys, poisonous toads,

and deadly pit vipers

also have to protect themselves
from the cold conditions.

Let's check it out. Sounds good.

Tom: So, you're
from new England?

Yeah, currently. I
live in massachusetts.

Cool. Where are you from?

Santa cruz, california.

What do you do in santa cruz?

I teach survival. Oh, you do?

Yeah. Cool.

How about you?

I'm a pediatrician.

Oh, wow. That's awesome.

That's cool.

Lisa: Tom seems
like a really nice guy.

He seems like he has a
lot of experience at this.

I definitely appreciate having
somebody who's done this a lot.

So, I'm not super
cold right now.

Are you doing all right?

Um...I'm doing okay.

It's definitely pretty
cold out right now.

Yeah.

Tom: I'm already
getting pretty cold,

so we're gonna
have to really get on it

and build a shelter and a fire.

Looks like a nice opening
up there would be nice.

It's high up above the river.

Honestly, like, I don't
know if it's getting any better.

Lisa: If we can --
let's spend a little time

trying to find a better path.

If we can find a
better path, cool.

If we can post up here,

I'll feel a little
bit better about it.

Lisa: I think it's
entirely likely

that tom's the one used
to being the one in charge,

the one running things.

Sound good? That's cool.

Cool.

Funny thing is I'm used
to being the one in charge

and the one running things,

so it's gonna be an
interesting pairing.

So, thoughts on shelter?

What kind of structure do
you think you want to build?

Well, I usually
talk about a-frames

or, like, lean-tos, but...

Um, okay.

It's a hard one 'cause
I kind of disagree.

So, I'm not sure
how to handle that.

Lisa: What is your
disagreement with that?

I think for now, the
day's getting late,

so if you're cool with it,
build, like, a small wikiup.

We'll run up here and see if --

seems like there's some decent
stuff up there for straight poles.

We need every
minute that we can get.

Hopefully when we're
warm and dry tonight,

we can really hash
out our teamwork

and how things are gonna go.

Right now, it's just
the pressure of day 1

to get some stuff done.

[ thunder rumbles ]

takes a long time to
make a good shelter,

and generally, when I
go in a situation like this,

from the second
I start the first day

until it's too dark to
see, I work on my shelter,

even if I think it's overkill.

Hey, tom? If you want
to take a break doing that

and let me do
it for a little bit.

I don't want you to get,
like, super crazy tired.

No, I'm good.

All right.

[ grunting ]

aah!

Tom: I was whacking
away at a log,

and it just kind of
deflected, nailed my wrist,

and gave me a pretty
good gash on the arm there.

It's a deep enough gash

that it's gonna need
something to keep it closed.

In this environment, if I
get a ton of dirt in there,

bad water in there,
it's gonna get infected.

Come on. Let's go wash it out.

I've seen bigger guys
than you pass out.

Lisa's a doctor,
and she tried to help.

Thing is, I know what it's like

to be on a first-day
survival situation.

You really just need to go
into this animalistic mode

where you just go, go, go.

Lisa: Not 10 minutes
after I suggested

that tom maybe take a
break with the machete,

he cuts himself.

And then he keeps on
working while he's bleeding,

so I'm frustrated because
he's not listening to me,

and that's just the way it is.

[ thunder rumbling ]

tom: It's freezing cold.

Do we really need
a fire right now?

From my experience,

I can definitely make
a fire that's gonna last,

you know, at least
a solid half an hour.

Narrator: Tom's
friction fire skills

will not work in
these wet conditions,

making lisa's fire
starter an invaluable tool.

I'd really rather not do the
mad scramble for firewood.

Uh-huh.

Lisa: Tom wants to make a fire.

I agree that we absolutely
are gonna need fire,

but without having
our shelter ready

and without having had
time to collect firewood,

starting a fire right now,
if it doesn't last the night,

then I don't think we
should necessarily

be spending this
energy on it right now.

I don't think
that's a good idea.

Keep in mind, we don't
have a whole lot of wood,

and it's getting dark.

Tom: There's certain
things I feel strongly about.

Obviously, I have

more wilderness survival
training and background,

and so there's some things

I'm just gonna
completely disagree with.

Everything is soaked through.
It just does not want to light.

If we don't get a fire
tonight, it's gonna be rough.

If we don't get a fire
and it rains tonight,

this is -- it's for real.

Like, our lives could
seriously be in jeopardy.

Oh, god.

Never seen anything like this.

Never, ever.

[ inhales, exhales deeply ]

wow.

Okay, it's go time.

Lisa: Obviously, having a fire

is gonna be really
important for us,

but not having our
shelter done could k*ll us.

Tom: Last night was rough.

Basically just shivering to
keep myself warm all night.

Lisa: We're at 5,000 feet.

We're in a cloud
forest in argentina,

and it's wet here,
it's chilly here.

I would say the
temperatures last night

got probably into the 50s.

We still don't work
fantastically well

as a team together.

I'm going for a walk.

All right.

I've been frustrated when
trying to work with tom

because he likes to do things

the way that he
likes to do things,

and sometimes less
of a collaboration.

Narrator: The unprecedented
conditions of argentina

are already putting tom
and lisa's patience and skills

to the ultimate test.

Before arriving,

a team of primitive survival
and special forces experts

assessed lisa and tom's skills,
experience, and mental fortitude

and assigned them each

a primitive survival
rating, or psr.

With 20 years as a
survivalist instructor,

tom was given a very
high initial score of 8.4,

squarely in the expert range.

But his frantic pace and
reluctance to work as a team

have already started
to lower his score.

Lisa possesses a solid
stable of basic skills

combined with high intelligence
and team-building abilities.

She scored in the
intermediate range with a 6.8,

and that number has
thus far remained steady.

They'll receive a
final psr evaluation

at the end of the 21-day
challenge if they make it.

Lisa: I could...If I so desired,

make this a real kind of
battle of the sexes thing.

Anything you can
do, I can do better.

There's no point in that.

Do I have any doubt

that I could do this
even if I didn't have tom?

Not really.

I think I could do this.

It's just been kind of a
funny realization to have.

Tom: The biggest challenge
that's just gonna be constant

this entire time
we're here is the cold.

And that's huge
because it never lets up.

Decided after a cold night

to build up rocks in
the front of the shelter

and to try to close off

as much of the front of
the shelter as possible.

Hopefully, that's gonna just
throw heat into the shelter

and not just have
it go up and out.

Until I'm confident that
that shelter is waterproof,

there isn't much point in
moving on to anything else.

Last night, tom was really
cold and really frustrated.

And so, I brainstorm.

How about if we
just make a wall?

He was like, "oh, I don't
know. I'll think about it."

in the morning, I came back
and he was building the wall.

And I felt like I
had a good idea,

and there was no acknowledgement
that it was a good idea

until he decided that he
was gonna make the wall,

and I would've helped.
I wanted to help.

Yeah.

Top end's looking better.

The bottom's
looking a little shy,

but we can always --

we can always add more.

In situations where
I've had disagreements

with people that I
was working with,

my m.O. Is usually to
say, "you know what?

I can take it."

we're gonna be here for
another 18 days together,

and I want and need a
partner that'll work with me.

If we are going to make it,

tom and I going to have to
figure out how to work together.

I totally understand that as
you get cranky and hungry,

stressful situations happen

and team dynamic
starts to break down.

The thing is, I know that
the second the sun drops,

things get miserable

if you haven't prepared
yourself enough.

I'm a little nervous

that there is possibly
thunder on the horizon.

Our shelter's just
not ready for that.

Things are looking a
little ominous out there.

I hope it's just a scare.

Narrator: High above the jungle,

another massive front
of cold mountain air

is on a collision course

with the warmer jet
stream of valley air below.

It's thundering out like crazy.

Just starting to rain.

And I'm definitely
nervous that, you know,

there's already drops
going on in our shelter.

[ thunder crashes ]

we got the fire going,

but honestly, I'm not
feeling too much heat off of it,

and the rain is
really coming down.

Tom? How exhausted
are you feeling?

Just hitting a low. I'm okay.

I'm getting kind of concerned

and maybe a little bit worried.

I just need a rest.

Tom: Last night was hard.

[ chuckles ]

a lot of suffering,
a lot of shivering.

We need to find a
way to stay warm.

That's our number-one
priority at this point.

Lisa: Tom lives in
santa cruz, california,

which is a lovely, lovely place

where it is 75
degrees year-round,

which I think has a big effect

on his ability to
handle the cold.

I live in boston, massachusetts,
and for the last two weeks,

being aware that I was coming
someplace that was kind of cold,

I've kept the heat in
my house at 50 degrees.

I'm hanging out in a tank
top and shorts in my house,

which is currently 54 degrees.

I think that I'm probably
a little better equipped.

He seems like he's really
struggling with the cold.

Narrator: Over
the next four days,

seven more inches of
rain drench the jungle,

and temperatures
hover in the mid 50s.

Tom's constant shivering
is burning essential calories

that he is unable to replace,
making him ever weaker.

Tom is sounding very
kind of despondent,

and, um...

I really hope he doesn't tap.

Tom: If it gets colder

and things don't improve
from what we have right now,

with the level I'm at,
I'm near hypothermic,

and if it gets worse,

it's just not gonna
be physically possible

to stay here.

I don't really want
to contemplate

going through this alone.

It's true that I ask myself the
same questions that he does,

but he's cold,

and he's saying that he's
not sure that he can do this,

be cold like this for long.

[ sighs ]

we can get through it.

Tom. Hey.

How you doing?

I'm good. I'm just, uh...

You know, just feels good
to lay down for a second.

You got to slow down, buddy.

I wish I had packed
on more pounds

before coming
out here, for sure.

By day 21, I'm gonna be --
I'm gonna be pretty emaciated.

Lisa: As a doctor,

I've been taught to
put emotion aside

and also to be very patient.

"no, it's okay."

tom and I have had some
differences since day 1,

but I think right now

the important thing
is to be there for him.

Narrator: A brief
pause from the rain

gives lisa the
opportunity to dig for food

that is more exposed
with warmer weather.

All I know is they
like rotted wood,

so I figured I'd come break
open some rotted wood

and see if I could
find any grubs in there.

We were kind of hoping that
we were gonna find snakes,

frogs, birds,
something decent-sized.

But because of all
the cold and the rain,

our options for food are pretty
much limited to grubs and worms.

But that's okay. It's
better than nothing.

They're not very exciting,
but we just need the calories.

I got something for
you. I got a fatty grub.

No way.

I also caught a
whole bunch of worms,

so I was gonna
cook them up, but --

cool. Yeah.

Getting the worm thing, I
think, is gonna be a great idea.

Here you go. Thank you so much.

I've actually got three more,
but the other ones are teeny,

and I've got like 10 worms.

Yeah, I think this is gonna
be our go-to food supply

for a while now.

Want to try this one?

Narrator: The small but
welcome meal of grubs and worms

has provided the survivalists
with about 120 calories

and 11 grams of protein each --

the equivalent of two
medium-sized eggs.

That's so good.

I'm really grateful for lisa
providing me with calories.

Mmm.

Their relief, however,
is short-lived,

as another massive storm
races toward them as night falls.

[ thunder crashes ]

so, tomorrow is
bark shingle day.

It's about the only
material that we have

that's realistically actually
gonna be waterproof

over a long period of time.

No more messing around.
No more messing around.

[ thunder rumbles ]

so, I was planning on taking
a long-ish hike up the creek.

Just gonna go up that way

until I find more
shelter stuff, collect it.

Yeah, I'm gonna -- I'll try to,
as I'm walking around today,

maybe find some bark
shingle type of stuff.

Lisa: Things with tom,

it just feels a little
different this morning.

Not great, not
fabulous, but better.

At times, this
situation in teamwork

is a little bit difficult,

but we're in a very
unique situation.

This is a difficult situation
with the cold and rain.

One of the issues that we've
been having with our shelter is

that we need to have it covered
in case a rainstorm comes in.

The only other solution
is to use bark shingles,

which is what's
gonna insulate us

and keep us warm
and keep the rain out.

Lisa: The sad thing
about doing this is

that I'm essentially
k*lling this tree,

but I told the tree that I
really needed the bark

so that I could
stay warm and dry.

Hopefully, it'll understand.

Tom and lisa are using the
bark of the eucalyptus tree

because of its pliability
and high oil content,

which makes it
more water resistant.

Lisa: The bark will
actually keep the water out

and the shingles will
let it run off to the sides,

and it won't wilt,
it won't weather,

the wind won't blow it away,

and it should keep
us dryer better

than the shingling
that we already had.

The next time that
torrential downpour happens,

we will be dry.

[ sighs ]

tom: Got a turkey right
up in the tree there.

I'd love to get him.

Lucky day, turkey.

We cross him again,
hopefully I'll get a shot.

The next nine days are gonna
be spent focusing on food.

Definitely looking a bit skinny

and concerned about
how skinny I'm gonna be

by the time this is done.

And I think my body is starting
to say, "we need a real meal."

tom: This is a turning point.

I've been super
focused on shelter,

but I need to
start looking ahead

and start thinking about food.

So, yeah, trapping is
a big thing right now.

I think today what I'd like
is making a fish basket trap,

just 'cause that could
be very reproducible.

That sounds good.

Lisa: Tom's got a
lot of experience.

He's studied way more
types of traps than I have.

So, the way the fish trap
works is you create this cone.

Fish are gonna enter.

They're gonna enter
this kind of cage or trap.

Once they pass through there
and they're in the actual trap,

because of some sort
of nature of the fish,

they don't swim right
back out the middle,

and therefore, people
are able to trap fish.

So, you're going up and over one

and then down
and around the next

and up and over one
and down around the next?

It's not really a weave.
I'm just tying them on.

Lisa and I are falling
into different roles,

and I think her
experience with trapping

is a little bit minimal.

Right now, my strength
is in making the fish traps,

making the turkey traps,

to make sure that they
are as perfect as possible.

There we go. Got a fish trap.

Looks good, tom.

Narrator: Tom
spends days 13 and 14

setting up a variety of
traps in the surrounding area,

including a turkey trap.

Tom: Now, when the
turkey comes through

and he's pecking at the
ground, he's gonna hit this stick,

releasing the toggle,

which is gonna tighten the
noose around the turkey's head.

Trapping is an absolute art.

It takes years to
get good at trapping.

I've set hundreds of traps.

If you slack on making a
trap at all, it's gonna fail.

I'm making it possible for him
to do things like make the trap,

which is hopefully
gonna feed us.

Lisa: Hey, good job, man.

I really, really, really
hope this works.

I really appreciate
the work you put in.

Thanks. Me too. Fingers crossed.

[ thunder rumbles ]

tom: Thunder is
cracking outside,

the rain is dumping,

and we are huddled
in the shelter.

So far...

Significantly better.

Dry-ish.

[ thunder crashes ]

narrator: The storm
thrashes the forest

throughout the
following day and night.

We're kind of concerned
that this might be a long one.

Hit a little bit
of a wall today.

Mostly a physical wall.

Tired and hungry.

No fish.

The worms, as I suspected,
were either eaten away,

or more likely, the river
just washed them away.

So, this trap
hasn't been hitting.

I don't see any evidence
that the turkey's come by.

You know, with the rain,

I knew that, you know,
this is just gonna get pelted

over and over like
our shelter was.

That, you know,

that was gonna knock
the bait around everywhere.

I pretty much
realized last night

that it wasn't gonna be my
day for catching a turkey.

How'd it go down there?

Well, the rain and the storms

really kind of messed
up our trapping situation.

Holy crap, it's cold up here.

You know, don't
make yourself too tired.

The traps haven't really
worked, so I'm getting frustrated.

I'm not looking at mother nature
as being my furry little friend

that's gonna wrap me in her
warm arms and take care of me.

What I need to
do is adapt myself

so that I can blend in
with my environment.

I'm gonna start dappling
myself up with other colors

that would create shadow
and blend into the dirt.

All right.

This is one of the areas
that I've seen turkey the most,

so at this point,

I just need to
stay still, not move,

and let them pass by.

[ turkey gobbles ]

that was the closest
I've been to a turkey yet

as I've been out here.

And unfortunately, it's just,
you know, it's one spear shot,

and then you got to
go back and warm up,

and so it's just been --

it's just a constant challenge
out here with the weather.

It's really limiting
our ability to survive.

Ugh! I almost had one.

Missed it by like a foot.

Mm-hmm.

Maybe not worth it,
but it was a close one.

Lisa: You can't be guaranteed
of getting food from hunting.

The traps haven't really worked.

Now that extraction is
just three days away,

I'm getting nervous that I
won't have the energy to make it.

[ thunder rumbles ]

here comes the downpour.

[ thunder crashes ]

narrator: More torrential rains
continue to pound lisa and tom,

confining them to their shelter,
unable to search for food.

Conditions are so dangerous

that the production crew
cannot reach them for two days.

[ horn honks ]

[ indistinct conversation ]

[ thunder rumbling ]

now on day 20,

their bodies are
depleted of energy

as extraction looms ahead.

Lisa: I'm tired.

I'm feeling the
effects of hunger.

My body is kind of done.

Tom: Unfortunately,
what we're battling

is the fact that we're 20
pounds, 30 pounds less

than we were the first day.

Sounds like we got at
least a solid day's hike.

I don't know if we're
gonna be able to do it

in one day, though.

No, I mean, considering how
much we're both broken down,

I think we should
probably plan for two days.

Narrator: In the event
of more overnight rain,

lisa and tom construct
a crude version

of a native-american
sled known as a travois

to transfer shingles
for a makeshift shelter.

Tom: Not 100%
confident in the travois,

but I hope to god it works,

'cause it would be nice

to not be soaking wet
and hypothermic tonight.

Narrator: On the first leg

of their treacherous
10-mile extraction journey,

lisa and tom face
an uphill battle,

dragging their
makeshift shelter supplies

up and over the steep hills

in hopes of making camp at
the halfway point by nightfall.

If they survive the night,

they face another five-mile
trek across streams and rivers

in order to arrive at a road

where they'll be extracted
by an evac vehicle.

Lisa: That's heavy, you know?

Getting that up over the
hill is gonna take a lot.

All right, well, just take
as much as you can.

I'll take as much as I can,

and we'll have to figure
out the rest as we go.

Oh.

Tom: Getting up the hill
without anything right now

at the energy level we
have is gonna be hard.

Getting up with an extra 30,
40 pounds of bark strapped to us

is really gonna be hard.

We should get going.

Let's do it.

I just got to take it slow.

Yeah.

This is kind of
what I was fearing

is that we're gonna get snagged
on everything gets in our way.

Yep.

[ grunts ]

aah!

What? Thorns.

Freaking thorns
everywhere, this whole forest.

I swear to god, like half the
plants here are made of thorns.

All right. You see
the hill up ahead?

Oh, yeah.

That's what we
got to do. Oh, god.

Just take a couple
steps at a time.

I'm very tired. But
this needs to be done.

So I just need
to get through it.

[ grunts ]

ow!

[ sighs ]

oh. Aah!

Tom: At this point, we
both have cuts in our feet.

We're both exhausted.

It's time to dig in, dig deep,

and find whatever
source of energy we can

to get the job done.

[ sighs ] give me a
second to breathe.

Oh. Aah!

[ sighs, grunts ]

oh, yeah.

I'm on my way.

Tom: Those are not happy clouds.

[ thunder rumbles ]

we're in a lot of trouble

if we don't get this shelter
up before that comes.

Lisa: That took every last
ounce of everything I had.

I am wasted.

Tom: We need to
get the fire started.

This is definitely a race as
I try to get this thing going.

Please, please, please.

Lisa: We need to
keep that fire going.

This is not gonna [bleep] do it.

It's so cold. This is not good.

Gonna be near hypothermia
the entire time we're out here.

Lisa: I'm really, really tired.

I'm really cold.

Sorry.

We're kind of concerned
that this might be a long one.

I'm really cold.

Narrator: It's been 20 days

since lisa and tom climbed
into the mountains of argentina,

and their individual
primitive survival ratings

are being reevaluated
at every step.

Tom's significant level of skill

has proven to be less effective
in this extreme environment,

and he has struggled
with both the cold

and the concept of teamwork.

While less skilled
than her teammate,

lisa has demonstrated
great patience

as well as a willingness to
put the success of the team

over her own sense of pride.

Their overall performance

will be re-evaluated at
the end of the challenge,

and their psrs will be
adjusted accordingly.

I'm really cold.

Narrator: The storm
rages into the evening,

and temperatures fall
into the coldest yet --

the low 40s.

Lisa and tom's bodies are
on the verge of hypothermia.

It's so freaking cold right now.

I'm surprised we
made it this far.

Definitely concerned
about myself and about lisa.

It's really just bone
chilling right now.

Hoping that, you know,
night doesn't get any colder.

A few hours later,

temperatures drop to
their lowest in three weeks.

Got about two or three
hours to go, hopefully less.

We don't really know, but
things are dismal right now.

I can only hope
morning comes soon.

Tom: It's day 21.

Last night was probably the
toughest thing I've ever done.

Just sitting there being
cold and wanting to tap

and knowing that it's right
within reach if I wanted to.

Narrator: To reach
their extraction point,

lisa and tom still face
a difficult five-mile trek

through thick jungle
and overflowing streams.

Lisa: Last night was
my breaking point.

I needed a lot
of help last night.

Tom was a huge help.

He kept me going,
he kept talking to me,

and now we're on
to our extraction site.

Watch these thorns
to the right here.

Okay.

Just ignore the pain.

Couldn't be doing
this without you, tom.

You holding up okay?

Doing all right.

Watch this one.
It's thorny as hell.

Okay.

We're doing great.

Ow!

Sounds like the
river's right up there.

It's getting louder.

Maybe this is the place.

I think it's gonna have to be.

Oh.

Narrator: The intense
rains of the past three weeks

have caused the rivers to swell

and flow at speeds of
over 20 miles per hour.

In their weakened condition,

one slip could wash
them away downriver.

All right, you up for this?

Yeah, man. Just be real careful.

That's a lot of water moving.

All right, real solid
foot placement.

Just be real careful, dude.
This is not the time to slip.

If you need me, just
yell and I'll reach for you.

All right.

Right behind me?

I'm right behind you. Okay.

Oh, it's cold.

How you doing? You all right?

Staying close behind you.

Yep. Grab a hand.

You okay? Okay.

Got a little push.

Okay, coming up right
here. You okay? Stable?

I'm all right so far.

Stay there? Yeah.

Yeah! Nice, lisa. All right.

Whoo! Made it across.

Tom: Oh, there it is. Nice.

Ah, yes! Yes! Whoo!

Tom: For me, being
out in the woods

has always been
somewhat of a loner activity.

But after everything lisa
and I have been through,

we've become such a team

that it seems really nice
to, you know, care about

and worry about the other

and make sure
that they're gonna be

just as successful as you are.

Yes! Yes! Yes! Yes! Yes! Yes!

Lisa: I think it would take
a significant amount of ego

to say that this makes
me an expert survivalist.

I still have a lot to learn,

but then when
the chips are down,

I am pretty tough.

Oh, we did it!

We did it! We did it! We
did it! We did it! We did it!

Let's get out of here!
Goodbye, yungas!

Bye, yungas!

I will not miss being
cold, but I will miss you.

Oh, thank you so much!
Thank you so much!

Narrator: Surviving the
unprecedented conditions

in the mountains of argentina

took an exceptional
physical and emotional toll

on the survivalists.

Over the course of the
wet and frigid 21 days,

tom lost a total of 30 pounds,

while lisa lost 26 pounds.

Tom was slow to realize the
benefits of working as a team,

and even with
his superior skills,

he struggled mightily
with the extreme cold.

Despite having less
experience than tom,

lisa's preparations
before the challenge

helped her handle the cold,

and she exhibited
great mental fortitude

in cultivating a positive
working relationship with tom.

As a result, lisa's psr score
improves from 6.8 to 7.4,

while tom's drops
from an 8.4 to a 7.9.

Lisa: First thing that
happened after I got back

was realizing how
crazy I smelled.

I smelled very, very strange.

Yes, I know. Yes, I know. Hi.

Wasn't just, like, smelled
bad. I smelled different.

It was weird.

Morning. It's day
22, and it's so cold.

Just kidding.

You know, seeing my girlfriend
when I got back from the trip

was just, you know,
it was amazing.

And it was really
good to see her.
