keith: Hey, alana, get out. Get out.

Sea snake.

They bite you, you're done.

I'm gonna go "rambo."

alana: Of course you are.

Oh, damn it. Where'd he go?

It's right there. Whoa.

Narrator: Two strangers...

One man and one woman, both experienced survivalists,

have chosen to put their skills to the ultimate test.

Just one victory, please!

They have no water, no food, and no clothes.

Their challenge is to survive for 21 days...

I don't want to go home.

...Knowing that the human body

can only live three days without water

and begins to shut down after three weeks without food.

Get out of there!

This is the everest of survival challenges.

Can a man and woman

survive alone in the wilderness naked and afraid?

Keith: I want off.

I want off this island.

Narrator: In the south pacific lies a large cluster of islands

whose scenic beauty obscures a harsh reality.

Beneath crystal-blue waters,

ravenous blacktip and whitetip sharks prowl the depths.

Highly-venomous sea snakes lurk in the pristine shallows.

Along it's white beaches, the crippling heat

can climb into triple digits,

and cyclones can devastate entire islands.

Beautiful on the surface, but deadly at heart --

this is fiji.

[ boat engine humming ]

I think the location's gonna be deceptively gorgeous,

and I think it's gonna be hot.

My name's alana barfield.

I'm in luxury retail -- freelance makeup artist.

I'm definitely a girly-girl

and kind of frilly on the outside,

but don't judge a book by its cover.

I grew up hunting and fishing.

I'm good with fire. I'm good with weapons.

And I can get definitely get things done.

I'm surprisingly calm.

I'm ready to go get it.

I am nervous, anxiety, a little bit of fear.

This is now real.

My name's keith busch.

I'm from seattle, washington, and I'm an a sober coach.

Quitting drugs and alcohol

was the hardest things I've ever done,

and I think that this will be right up there with it,

if not harder.

I was in the army as a reservist for 10 years.

I love the outdoors.

I've always considered myself

as someone who could survive under any situation.

But the heat is intense.

I don't have a lot of experience in this type of environment,

so that's gonna be a major concern out there --

getting things done.

Alana: I hope he can look past my appearance

and doesn't try to treat me like a damsel in distress

or a helpless little girl.

That will drive me insane.

This island's not gonna know what hit it.

Keith: I'm a little nervous. I might be attracted to her.

Here we go.

There's certain things that happen to the human body

that I can only pray don't happen.

See you guys in 21 days.

[ grunts ]

alana: I am single, but romance?

I think it's highly unlikely, just given the circumstances.

But you never know.

Well, hi there. I'm keith.

[ laughs ] I'm alana.

Nice to meet you, alana. Nice to meet you.

It's so embarrassing we wore the same thing.

[ laughs ]

keith: I first see alana and I'm thinking,

"wow, here's a very attractive girl,

and hopefully she's capable."

and then, also, I notice that she's very pale,

so I'm instantly concerned about the sun and exposure.

Let's see what we got.

Narrator: Alana and keith are each allowed one survival item.

Well, I brought a machete.

Nice.

So at least we'll be able to make a shelter pretty easily.

I brought a fire starter.

Yes. Thank you, lord jesus.

Keith and alana are also given personal cameras

to document their experience.

Day one on the island.

We'll see how we look on day 21.

Of course the woman would have the map.

Obviously. [ laughs ]

narrator: From the barren strip of land

where they have been dropped off,

alana and keith will make their way inland

through coarse and dense sawgrass

to this small beach on the opposite side of the island

that they hope will provide a more plentiful harvest

of plant life and, most importantly,

a source of fresh water.

After 21 days, they will break camp

and journey around the east side of the island

through stingray and sea snake territory,

tackling dense jungle,

and finally climbing the steep lava cliff

to reach their extraction point.

Head out?

Yep. Let's do it.

A small crew will follow alana and keith

with orders not to intervene

unless there is a medical emergency.

Keith: That way?

Yeah. Straight through.

Keith and alana underwent a tough selection process.

Their physical and psychological survival abilities

were evaluated by experts according to three categories --

skill, experience, and mental toughness.

Keith's numerous survival and outdoor adventures

earned him high "skill" marks,

but his addictive personality and need for thrills

could lead to erratic behavior and a lack of focus.

Alana ranks in the top percentile

of problem-solving and mental fortitude,

but her reluctance to rely on others

could hurt her and her partner.

Keith and alana have each been given

an overall primitive survival rating, or "psr."

keith scores an overall psr of 6.3, and alana scores a 6.1.

Our survival experts will reevaluate their psr

at the end of the 21 days.

It's so fricking hot.

Yeah, it's hot, hot, hot.

It's like when you open the oven door

and that heat just blankets out.

I'm a ginger.

There's a reason that island civilizations

are not made up of redheaded people.

This is not where I'm supposed to be.

This is gonna hurt.

Careful right through there. It's a lot of thorns.

Oh, yeah. Sticks with the ferns.

[ grunts ] son of a --

walking through the grass is like having paper cuts

on your entire body from the waist down.

I -- I'm getting to where I really hate grass.

Hate grass.

Oh, you're too young to hate.

Doing okay? Yeah.

My feet are already bleeding.

Ow.

Careful, it's -- it's painful. [ chuckles ]

speak for yourself. [ laughs ]

oh. Oh, my bad.

I'm just fine.

He's a little older than I was expecting.

He seems like the type who thinks that women are helpless

and weak and dainty and can't do anything.

Women are tough.

Ow.

We need to really get a handle on our water source,

and then start checking out --

build a fire. ...Possible little --

I'd like to build a fire before rain gets here.

Yeah.

I plan on boiling anything we --

yeah, always a good idea.

The beach.

We're here.

The beach. No more grass blades.

Keith: We've used up a lot of water today,

and we need to replenish those fluids.

Actually, that's perfect.

We can pull water from there and boil the hell out of it.

Yeah.

Where's your flint and steel?

In the bag.

In your bag? That's what I though.

So, I was just -- wasn't taking over.

Trying to help out.

Alana: I might be picking up a little bit of stubbornness,

but I'm willing to play sidecar for a little while,

just to kind of feel things out,

see how the partnership kind of develops.

I just feels really damp,

even just when I grab hold of this nest to shape it.

Just, the whole thing just feels damp.

There's no escaping the moisture around here.

Oh, don't go out. Don't go out. Don't go out.

Hey, keith!

Bring some wood with you. We got fire.

That is so awesome.

I'm in love... With the fire.

But I'm just kidding.

Keith: We're gonna use a bamboo container.

They're watertight.

You can actually drop hot rocks in the water

and boil by hot rocks and kill 99% of the bacteria.

Instead of having our heating pan,

you put the heating pan in the water.

Come on, baby.

I see bubbles. I see bubbles.

It does work.

Not even close.

We need a lot more rocks. Mm-hmm.

Eventually that will boil.

It's never a good idea to drink untreated water,

and I do not feel like having the squirts for a few days

because I was too thirsty to be smart and boil water.

[ spits ]

no.

Don't swallow that.

[ spits ]

perfect growing temperature for bacteria.

I have to admit defeat.

Narrator: The average human body

loses 2 pints of water per hour of work.

After a 3-mile hike in the scorching heat,

alana and keith have easily tripled that amount.

Without replenishing it, they run the risk

of slipping into hypovolemic shock in under 24 hours.

But now, with daylight fading quickly,

they must construct a temporary shelter

before night descends on the island.

I'm gonna have to use infrared 'cause it's getting dark.

So, the shelter's just about finished.

We've got a fire going.

Too bad there's -- I mean, there might be some water vines

within...Right here, but --

not tonight.

Yeah, not tonight. Not tonight.

I'm [bleep] exhausted.

That's one of the things we have to really look at tomorrow --

just water supply.

Keith: [ chuckling ] I want to go to sleep.

Keith: Morning of day two.

Last night wasn't very good.

It kind of sucked.

It was freezing and, you know, we're not a couple,

so we're not -- we're not snuggling.

We went back-to-back, which warmed me up a little bit.

But it was just cold as hell.

So, our biggest issue, I think right now,

is sourcing water, treating water.

We need water.

Narrator: Nearly 30 hours into their survival challenge,

alana and keith have yet to secure a method

to purify drinking water.

They head inland

to search for any alternate hydration source

that won't require boiling.

Keith: Hypothetically, if you chop a banana tree

about 6 inches to 8 inches off the ground

and then hollow it out, it will then fill up with water.

Alana: And then we twist up a little piece of --

I think we have the same idea.

Yeah, that's gonna work. That's gonna work.

[ groans ]

ohh, man. Yeah.

Tastes like a -- battery acid.

Yeah.

I'm thirstier now than I was the first time I tried it.

You see that coconut tree there?

Yeah. That lower...?

Yeah, I got my eye on that.

We can go chop that down.

It'll take all of 15 minutes.

It's a big base.

It's gonna take -- it's gonna take all day.

I think we should see what's on the ground first.

I think. No. Really?

I've been looking hard for coconuts.

Alana: I'm seeing a lot of ambitious ideas from keith

that spend a lot of energy,

and I'm all about trying to conserve calories,

'cause we're still operating on minimal intake.

It will come down.

[ buzzing ]

25% there.

It's a -- it's a third of the way through.

But I'm starting to get blisters,

and I don't want to get blisters.

Well, you don't have to do it all at once.

15 minutes.

We have water right here.

If we just work together on containing it

and making it purified,

that could save a lot of elbow grease.

[ chuckling ] I'm worn out.

Oh, come on.

There we go. There we go.

Timber!

Bitch.

See if it was worth it, huh?

It's empty.

There's nothing coming out.

He was really adamant

about chopping down this huge coconut tree.

We have the green coconuts,

which were empty of water 'cause they were too young.

He tries to perform,

and all it's doing is hurting him

and using up calories that we don't have.

We just need to find water.

Keith: I am hurting.

I mean, bad.

We're still thirsty.

This is the worst I've felt in a long time.

This is the hardest thing I've ever done.

Narrator: Coming up...

Keith: Pouring down rain.

The wind just picked up.

You bitch more than anyone I know.

Alana: No, I do not. You are a prima donna.

Yes, you are.

Whatever, mister "I need a pillow,"

"I need more padding," "my feet hurt."

I'm sorry to let a lot of people down.

Just stupid. My body can't do it.

I'm just bone-tired.

[ voice breaking ] you know what? Just leave me alone.

Timber!

It's empty.

Narrator: Two days into their survival challenge

on a remote fijian island,

alana and keith have failed to purify

or secure drinkable water.

Now, on day three,

with their bodies beginning to shut down from dehydration,

they're in dire need of a fresh-water source.

They risk further dehydration

by heading inland in search of fluids.

Keith: We're heading to get water now.

Part of the trek is through this area

that really sucks for the feet.

We're gonna go because we need water.

We decided to start early, before the heat, today.

That way. Yeah.

Just trying to find the path of least sawblade bushes.

Alana: We've had no water.

It's really draining on my mental state.

It really is.

Keith: It is hot.

It has been the most hellacious day, as far as heat.

Got to be the hottest day. Got to be.

Incredible heat.

Yeah, see, I wouldn't drink that.

Even though it's water.

Alana: If it's rain, I'd say go for it.

Keith: I don't think it's rainwater, though.

Narrator: Without knowing how long the water has been there,

keith and alana risk infection from parasites or insect larvae.

I'm not gonna pass up clean water.

Yeah, I think -- I think our chances are pretty good.

Just, where it is, it's had some sun exposure.

And there's -- only things I'm seeing in it

are freshly-fallen little plant pieces.

It's better than nothing.

[ slurps ]

mm.

I think this is as clean as we're gonna find.

This whole trek was worth it to me at this point.

Yeah, this is worth the walk, no matter what.

Keith: Clean water.

We both are drinking as much of that as we can.

Oh, the first, like, complete gulps.

We got completely hydrated for the day,

so we'll be good at least until tomorrow, now.

I drank a lot.

Yeah, I drank a ton.

Narrator: The rainwater pools have saved keith and alana

from extreme dehydration for now,

but the tropical environment is always ready

to throw down a new challenge.

[ thunder rumbles ]

[ raindrops falling ]

[ groans ] mm-hmm.

Fricking sucks.

Keith: Pouring down rain.

Our humble abode leaks.

Alana: Pretty miserable.

Um, and now the wind has picked up.

[ chuckling ] tough night.

I'm just bone-tired.

This is the worst I've felt in a long time,

as far as body-wise.

My body can't take it.

[ thunder rumbles ]

all right, so, it's been raining pretty hard

all late night into the early morning.

[ sighs ]

alana?

Keith: Something's giving me diarrhea.

Uh-oh.

And I'm guessing it's the water.

Well, it's not affecting me, so maybe it'll --

something it'll -- maybe it'll just pass.

How you holding up?

You around the edge of throwing up?

Yeah.

Okay. For a little bit.

Keith: My intestines are cramping up.

I feel like vomiting.

I'm 100% dehydrated.

I just feel like absolute [bleep]

and that's not the bad part.

The bad part is, I'm letting my partner down,

and she's got to do everything while I'm bedridden.

I suck right now, and it's just b.S.

Alana: I don't want to have to do this by myself,

but if he's gonna get over whatever this bug is,

he's gonna have to ease up on the tarzan shenanigans,

like cutting down the tree, and just let his body rest.

'cause if he gets taken out of here --

I just don't want that to happen.

I'm just not even gonna think about that.

That's not an option. He'll feel better soon.

[ groans ]

keith: By far the worst night ever in my entire life.

So...

Just can't do it.

I bit off more than I could chew.

Physically, it's just not happening.

It's just not -- it won't keep up.

My body will not keep up.

And, um...

Sorry to let a lot of people down.

I want off.

I want off this island.

Keith: This is harder than I ever thought it'd be,

and it's reminiscent of the day that I checked into rehab.

It is the same exact feeling inside.

And my body is telling me "that's enough."

so, um...I guarantee you, I'm not being a wussy about it.

But my body's telling me "stop what you're doing

or we're gonna kill you."

you got to listen to your body and what it's telling you.

But one of the main things is,

is I don't want to let you down.

Now, are you absolutely sure you don't have it?

I'm 98%.

What if we just take today

really, really slowly, you know?

Let's improve the roof --

yeah, we do have to improve the roof,

but if we keep it simple, we can patch,

just kind of address the leaks where they are.

We'll fix the shelter and stuff,

and I'll go on as if I'm not leaving.

And, you know, see -- see how I feel.

[ voice breaking] knowing how much I went through

to try and get to this point,

I don't want to let down my family or my partner here.

Ooh, now it's getting steamy.

Yep.

There's a couple pretty big ones.

Okay.

Can you stack them so we can drag them?

Oh, here's some bananas.

Alana! There we go.

The meal in a peel.

[ laughing ] that was so corny.

[ laughs ] but I actually like it.

That was definitely a great find.

This makes me feel great,

to find a nice little bounty of fruit.

It's awesome.

Nice.

Finding the young bananas,

I think it kind of snapped him out of his blues.

Keith: This is the hardest thing I've ever done.

Just gonna approach it just like I do sobriety --

one day at a time.

If one day doesn't work, break it down to one hour.

When an hour doesn't work, break it down to one minute.

We can do anything for one minute.

Narrator: After another two-day period of no rain

and searing temperatures,

keith and alana once again find themselves

fighting imminent dehydration.

With their freshwater pools almost dried out,

they cut new bamboo water containers and hope for rain.

I'm feeling really light-headed.

Keith: Just take a break. I'll -- I'll do it.

You're no good to me passed out.

[ jamaican accent ] yeah, man.

[ normal voice ] take this baby home.

I just need a minute.

You doing okay? No.

It's like I can't breathe, and I'm dizzy.

I feel like I'm this close to passing out.

Things get blurry.

It's creepy.

You never got blurry vision

after working out really hard when it was too hot?

I don't know. Maybe.

I can't think of a story about it right now.

Just asking to try and see if there's some correlation.

The correlation is I'm [bleep] like, dehydrated

and hungry and sunburned.

That's the correlation.

Keith: I know she's exhausted,

and I need to be supportive for her.

But bitchy behavior does get old.

[ buzzing ]

narrator: In the past 10 days,

keith and alana have consumed mere hundreds of calories

when they need thousands daily.

The pain of malnutrition forces them

out into the searing heat of day in search of food.

Alana: Got to get a little more protein into our diet.

Probably gonna focus on crab,

'cause we've seen a lot of those along the rocks,

to the point where I'm gonna start throwing

some of the methodology out the window and just going for it.

If it see it, I'm gonna grab it.

Oh, hi.

[ grunts ]

aah! [bleep]

keith, come here. There's a crab.

Keith: Coming. Kind of like stone looking.

I'm probably gonna fling him at you onto the beach.

Oh. Hey, buddy. How's it going? Hi.

Oh, so unlucky.

Hey, alana, get out. Get out.

Narrator: Keith spots one of the island's deadliest creatures.

[bleep] a [bleep] big.

One bite from a banded sea krait can cause paralysis

within six hours and is fatal if untreated.

If they bite you, you're done.

Alana: I wouldn't mess with the sea snake.

Really?

I think they're edible if you cut below the poison packs.

I'm gonna go "rambo."

alana: Of course you are.

Hey, buddy.

You digging -- are you digging for something?

[ grunts ] oh, damn it.

Okay, now we got pissed-off sea snake.

Where'd he go? It's coming back around.

Okay, watch out.

It's right there.

Damn it. Whoa!

Oh, damn it.

Now we got pissed-off sea snake.

Where'd he go? Alana: It's coming back around.

Okay, watch out.

It's right there.

Damn it. Whoa!

I think he's fine.

Just injured him.

I'm okay with injuring a sea snake.

If you're gonna injure it,

you should at least kill it all the way.

Alana: I mean, there's crabs there.

He doesn't need to mess with a sea snake.

He's just trying to be macho, show off, or whatever.

I honestly think that whole thing unnecessary.

Didn't need to mess with it.

Stupid. Unnecessary risk.

I'm gonna leave this by you

so we can keep the flies from getting in there and...

I have more flies attracted to me than these guys.

But okay.

Fine, I'll -- just leave it over here.

I'll -- I'll do it if it's too much trouble.

I'm kidding. Can you try and relax today?

'cause you're being a major, major

over-sensitive person right now.

It's getting very, very old.

Well, you're not my favorite person today

after that little "rambo" display,

which was so awesome, on the beach.

Oh, did that hurt your feelings?

It was just stupid.

I actually don't need your approval on that.

That really makes me question our chances here --

your doing crap like that.

The thing is, if you're mad at me today

'cause of the snake thing,

you've been this way for four days.

I've been --

this way for four days.

Attempting to kill things and leave them there --

you've been a total hyper-sensitive person

for four days.

I'm just tired of hearing you complain

about every little thing.

That's what is making me in a bad mood for the four days.

You bitch more than anyone I know.

No, I do not. You are a prima donna.

Yes, you are.

Whatever, mister "I need a pillow,"

"I need more padding," "my feet hurt."

you said the exact same things.

Maybe you can't hear yourself,

but you say the exact same things.

You did.

I guess I can't, 'cause I don't complain as much as you.

You're right. You complain twice as much.

Whatever.

Like, I'm just --

I'm just trying to stay focused on what we need.

We need water and we need food.

Keith: My hope after catching these crabs

was that this meal would be all fun.

Instead, it was kind of a downer.

Alana: I'm here to survive and get out of here in one piece.

So we got to tell it like it is and be honest,

and if people's feelings get hurt, so be it.

But we got to be on the same page.

Keith: Oh, my god.

I don't know if I can do this for 10 more days.

Keith is not doing too great.

Just gonna turn it around a little bit.

May have had a seizure.

The medic's on his way, check him out.

[ radio chatter ]

narrator: Alana finds keith barely conscious

after suffering an apparent seizure

in the early morning hours of day 11.

Crew medics quickly evac keith

and rush him to the nearest hospital on the mainland.

Fearing head trauma, local doctors

immediately admit keith and begin neurological testing.

Halfway through the challenge,

keith has lost nearly 10% of his body weight,

and he's displaying symptoms

usually associated with seizure and head trauma.

While keith's mri results are inconclusive,

he's severely dehydrated

and exhibits signs of acute fatigue.

Local medical staff recommend that he remain hospitalized

for further testing, forcing keith to tap out on day 11.

Alana: Well, today -- so much going through my head.

Um, it's down to me, myself, and I.

Just me and this big island all to myself.

I'll give it my best shot.

I did not come here

for anything less than the full stretch.

Was hoping to have a partner for the duration of it --

at least more than halfway.

But it's just another challenge that I'll need to overcome,

just one more thing for me to contend with.

I may be biting off more than I can chew with this load.

No one's gonna be watching my back.

It's all up to me --

whether I eat, I sleep, I drink, I'm warm at night.

It's all up to me.

Narrator: With her extraction still seven days away

and her body dramatically weakened,

alana decides to brave the dangerous shallow waters

in search of protein.

Alana: I get to the beach,

and I immediately see these little black tips.

I see two right there.

Narrator: These young blacktip sharks have come to feed,

which is when they're most aggressive,

and their serrated teeth

could easily inflict a deep and painful bite.

Alana: There's a lot of protein in one shark.

I mean, that's probably all the protein I'd need

for the next couple of days.

[ grunts ]

ah, it's three of them now.

[ grunts ]

I hit him.

I just couldn't -- couldn't penetrate that tough skin.

I'm so beat.

I'm really disappointed.

I don't have the fat reserves to keep going,

so it's a little worrisome.

[ shuffling ]

whoa [bleep]

okay, something just ran away.

Like, scuttled fast.

I still hear it.

[ shuffling ]

I don't see anything.

Something's going on out here.

What the hell?

Oh, my gosh. My heart is pounding.

Something is charging me.

Oh [bleep ]

narrator: Two weeks into keith and alana's 21-day survival challenge,

only alana remains.

Before they began, they were both given

a primitive survival rating, or "psr,"

and will be reevaluated at the end of the challenge.

Since keith had to be removed from the island,

his final psr will be significantly reduced.

Alana's psr has remained steady,

but now, without a partner, she faces the daunting reality

of completing the 21-day challenge alone...

Alana: I'm really nervous.

So much harder doing this by myself.

Narrator: ...A feat never before accomplished.

[ shuffling ]

alana: Whoa [bleep]

okay, something just ran away.

Something is charging me.

I'm hoping to find something to explain that sound,

'cause it was -- it was pretty intense.

It's like I was being charged by animals.

Some loose rocks over here.

I might've been one of those.

But it sounded so much closer.

When you're alone in the dark in the middle of the night

with no one around and you hear these crazy sounds,

I mean, your imagination just goes wild.

My brain is starting to slack off on me a little bit.

I'm crashing.

All I've had today is bananas, pretty much, to eat.

I need some protein.

Narrator: With no energy left to hunt,

alana resorts to scavenging whatever resources she can find.

Alana: The wrong place at the wrong time.

Much better cooked,

but it was too small to bother trying to pick apart,

so I just ate the whole thing, shell and all.

Narrator: Starvation tightens its grip on alana.

Her body is consuming itself from within.

With each passing moment,

completing the grueling extraction journey on day 21

seems less and less likely.

Now alana's greatest enemy is time.

Alana: I'm getting out of here.

But my energy level's so low,

I don't know if I can't make it up there,

which is gonna take every ounce of energy that I have

and every muscle in my body.

Fat termites.

Just the protein boost I need.

[ snaps ]

looks like I have quite a ways to walk ahead of me.

Whatever it takes, I got to get out of here.

Narrator: In order to be rescued,

alana will have to journey around the island,

wading through stingray and sea snake territory,

traverse a dense jungle, and scale a sharp, rocky outcrop

to a high point on the east side of the island.

There, she will wait for a helicopter

to take her back to civilization.

[ sighing ] all right.

Let's do this.

The hike is tough.

Lots of rocks.

Then you got to watch out for stingrays.

With all the sea snakes we've spotted around here,

I have to watch for that.

It is very hot and very sunny.

The heat is just oppressive.

That must be it -- the top of that big hill.

That's my ticket out of here.

Just get to the top of that rock.

I'm a little concerned about my energy levels.

I'm already tired.

Ow. [bleep]

razor-blade grass.

Really thick over here,

so I'm taking my steps very carefully.

I don't want to bleed to death.

Oh, my god.

So, this is it.

I am so ready to get out of here.

I have to admit, when I realized that keith wasn't coming back,

there was a split second where I thought

that I would go ahead and tap out, too.

[ helicopter blades whirring in distance ]

[ sighs ] I hear my ride coming.

I can't wait. It's gonna feel so good to get in there.

I have learned how I deal with solitude,

not knowing where my next meal's gonna come from.

And I've learned a lot about what's important to me

when everything's stripped away.

I definitely hear some propellers.

[ chuckling ] and it sounds so beautiful right now.

There it is! There it is!

Whoo!

[ radio chatter ]

I feel changed.

The hardest thing I've ever done in my life.

Knowing that I came out of it --

that's just gonna be a source of strength and inspiration

to me, probably for the rest of my life.

Whoo!

Yes!

Narrator: Over the course of the 21 days,

alana and keith went through massive transformations.

Even though he abandoned the challenge on day 11,

keith lost 18 pounds.

Alana lost a total of 17.

Upon completing blood work and other medical assessments,

keith was discharged from the hospital

with a clean bill of health.

Alana showed tremendous mental fortitude after keith left.

She is the first person to ever reach the end

of the 21-day challenge without a partner.

This brings her survival rating up from 6.1. To 7.0,

while keith's rating falls to a 4.5,

proving that it takes more than meets the eye

to survive naked and afraid.

The girl that works at the fancy store in the mall

and does makeup -- I did it.
