Alien Crash-Lands on the Deadliest Planet Filled With Giant Immortal Monsters

On the planet Yaya Prime, a runt

predator named Deck is on a training

session. He uses a variety of tools to

travel the land until he enters a cave

where his scanner tells him that his

brother is hiding nearby. Deck attacks

behind him with his sword and Quay

blocks it just in time. The brothers

begin to fight and Quay keeps taunting

Deck as they move, reminding him to use

the cave to his advantage. Swords keep

on clashing as they move all over the

cave and after exchanging enough blows,

Quay manages to corner Deck but doesn't

kill him. When Deck refuses to yield,

Quay cuts the pillar they're standing

on, and Deck falls into the abyss. He

manages to save himself by holding on to

the wall. He climbs back up and attacks

Quay again. Later on their ship, Quay

tells Deck it's time to choose a prey so

he can earn his place in the Aya clan.

Deck wants to go to Jenna, also known as

the death planet, to hunt the unkillable

monster, Callisk. Even their father

fears it, and that's why Deck wants to

go after it. He's tired of his dad

seeing him as a weakling. Quay doesn't

approve. However, Deck makes his vow. At

that moment, their father, Njar,

returns, and Deck welcomes his honor

with a sample of his blood. Jar wonders

why Deck is alive, revealing he ordered

Quay to kill him because he's too weak

to be part of the clan. However, Quay

thinks Deck deserves a chance to prove

himself. An angry Jar throws a device

that captures Deck and tells Quay to

kill him now, but instead, Quay frees

him and activates his laser to send him

into the ship. Then, Quay activates his

shield to protect his brother since Jar

opens fire. After closing the ship to

keep Deck from escaping, Quay starts

fighting Jar and in just a few moves, he

manages to disarm him. Jar activates his

camouflage cloak, but Quay keeps

punching. Sonjar stabs his hand before

chopping his arm off. Then Jar strikes

his son down and Quay starts crawling

away, reaching for his arm rather than

his sword. Jar calls him weak and stabs

him. So Quay uses his last breath to

activate the ship so his brother can go

to Jenna. Deck watches Nar Lequay's neck

as the ship's launch knocks him out.

Sometime later, Deck is awakened by an

alarm. The ship has been damaged by the

debris in orbit and is hurling towards

Jenna. Deck rushes to the seat and

ejects it, so it starts falling at great

speed through the Jenna sky. When a bird

almost crashes into him, he activates

the shield. He ends up crashing in the

jungle and he roars in frustration.

Determined to find the monster, Deck

takes stock of his weapons to confirm

everything is working well. He's

startled by a noise nearby and starts

searching the area. Suddenly, a

vine-like creature takes him by surprise

and steals one of his weapons. Deck gets

his sword ready, but a second vine grabs

his arm, and he has to cut this one

while the first one escapes.

Unfortunately, more vines appear and

reach for him until they grab his leg to

drag him on the ground. Deck manages to

take his bow to shoot his captor to

force it to drop him and punches the

vine to keep it back. Then, Deck runs to

retrieve his sword and quickly slashes

the vines that keep attacking him. No

matter how many he cuts down, though,

more and more keep coming and they even

start attacking together. Deck quickly

dodges a few blows and jumps on top of a

vine to run on it, which helps him get

to the top of a cliff. The vines can't

reach him up there, and now Deck has a

good view of the planet, which looks

terrifying. Afterward, Deck washes his

wound in the river and uses his scanner

to find a medicinal plant that can serve

as a bomb. On a leaf, he finds a worm

that starts growing red spheres, and

when he throws it away, it explodes.

Then, he goes out to explore and search

for the callusk. On a big field, he

finds some strange red plants that keep

hissing at him. So, he moves carefully

to avoid them. At that moment, Deck

hears a voice talking in a strange

language and looks up to see Thea

trapped in a huge nest. Realizing he

can't understand her, Theia changes to

the universal translator, which confirms

she's an android known as a synthetic.

Suddenly, a Jenna Vulture appears nearby

and grabs a rock to throw at the strange

plants. This makes the pods explode with

red smoke and shoot their needles, which

Deck quickly dodges. Thea explains that

the needles can paralyze him so that the

vulture can eat him. When Thea offers

her help, Deck says that the Yaoya hunt

alone, and Thea guesses he's here for

the callusk. The vulture throws more

rocks and multiple plants are activated,

so Deck is hit by the needles. As he

starts feeling dizzy, Thea asks for a

weapon, so he tosses one of his blades

at her before collapsing. The vulture

flies down and is about to eat him when

Thea tackles the beast and brutally

kills it with the blade. Deck sees her

wave before passing out. Minutes later,

Deck wakes up because Thea has given him

an antidote made from the same flower.

Deck stands up and helps Thea do the

same, only to notice that she's missing

half her body. She explains she's a

synthetic scent by the Way and Utani

Corporation because humans can't live on

this planet, but Deck doesn't care and

drops her. Thea then points out that

many Yaoya have come for the callus and

none of them survived, but she did. If

he takes her with him, she'll guide him

to the call's den. That way, she gets

her legs and he gets his trophy. Deck

realizes that it was the callus who

destroyed her, but he's still not

interested. However, when Thea calls

herself a useful tool, Deck doesn't see

it as breaking the code anymore and

agrees to bring her along. While they

travel, Thea never shuts up and keeps

asking questions. At the river, some

peculiar worms begin shooting acid at

them. So, Deck carries Thea on his back

to run faster. Unfortunately, he finds

the way blocked and Thea uses the chance

to teach him a lesson. She throws a

sticky fruit on the ground and the

creatures rush to eat it. Now they

aren't shooting anymore. Once they leave

the river, Deck cuts down a bunch of

vines and ties Thea to his back to move

more easily. In the evening, they

stopped to camp for the night and Deck

uses his device for light. Thea shares

that her crew arrived on Jenna 2 years

ago and she was trapped in the vulture's

nest for almost 2 weeks. She had hoped

that another synthetic named Tessa would

come for her and tells Deck that they

have a higher sensitivity than other

models. Dex sees sensitivity as a

weakness, but Thea thinks it's an

advantage to understand other creatures.

Thea used to be stuck in the lab, but

one day Tessa brought her out to

explore. Unfortunately, that was also

the day that the callusk attacked them.

Meanwhile, at the crew's new base, it's

revealed that Tessa looks just like

Thea. She received severe damage during

the callusk attack. So, now she's in a

pod being repaired. Tessa keeps

repeating Thea's name and remembering

the incident, so the computer reminds

her that her priority is to catch the

callusk. The computer also detects the

presence of a Yaoya and classifies him

as a threat. When Tessa finally wakes

up, she's told that Theo was captured by

the Ya. In the morning, Deck goes out to

hunt for food. He comes across a bone

bison, which is usually callous food.

Deck tries to move ahead, but has to

move back when he discovers that this

field is covered in razor grass. When

Deck's about to throw his blade, a small

creature jumps from a tree and lands

next to the duo. Thea can't identify it,

and Deck roars at it, but the little guy

just roars back. Then the creature

starts chasing after the bison without

issues because its hard skin isn't hurt

by the razor grass. Furious about having

competition, Deck starts jumping from

tree to tree to follow the bison, too.

The weight breaks a branch and the duo

falls. So, Deck pierces the tree with

his blade and stops the fall right

before they touch the dangerous grass.

When the bison runs near them, Deck

jumps on it and stabs it. However, the

bison throws them off by using another

tree. The small creature rolls ahead of

them and a frustrated Deck tackles it to

start a fight, which means Thea often

gets smooshed. The little guy has

surprising strength, but after some

struggle, Deck manages to grab it by its

neck. At that moment, the bison comes

running toward them. So, Deck throws his

sword and holds the bison's mouth open

as the blade proceeds to cut it in half.

Deck roars to celebrate a successful

hunt, only for a tentacle to suddenly

grab his leg and lift him. The duo has

been captured by a Luna bug whose tight

tentacle tongue is stopping Deck from

activating his devices. When they're

about to be eaten, the little creature

jumps into the Luna Bug's mouth and

blocks its teeth with its hard skin,

breaking them. The Luna bug is in so

much pain that it spits them out and

leaves by walking on the razor grass.

Desperate for revenge, Deck cuts down a

tree to use it as a bridge. The little

creature is rolling down the field

already, and the Luna bug captures it

with its tongue, but at that moment,

Deck lands on its head. He stabs the

monster with his sword and makes a large

cut that finally kills it. Meanwhile,

Tessa and her crew of synthetics are

searching for Thea. They find Deck's pod

before they're attacked by the vines.

The crew quickly opens fire to slow them

down. Then, they activate their

flamethrowers to burn all the vines

down. In the evening, Deck and Thea make

camp again. The little creature is still

following them and copying every move of

Dex because it's impressed by how he

hunted the bison. Thea names it Bud

while Deck shares the roasted meat. Thea

asks Deck about his family, so he tells

him what happened with his brother and

father, but he refuses to accept he's

grieving when Thea uses that word. He

points out that Tessa counts as her

sister, and Thea likes the concept. In

the middle of the night, Tessa and her

crew find Deck's ship, which crashed

after he jumped out. There are many Yoja

weapons that Tessa finds interesting,

including a grenade that freezes her

hand. The next morning, Deck grabs Thea

and leaves without Bud, insisting that

he hunts alone, and Thea doesn't count

because she's a tool. Thea tells him

about wolves and how they hunt in packs,

but the alpha isn't the one who hunts

the most, it's the one who protects the

pack. Deck misses the point and says

he'll be the alpha who kills the most.

After finding a call fang near the

river, the duo continues traveling in

that direction and reaches Thea's base,

which has been completely destroyed by

the beast. Among dozens of synthetic

bodies, Thea finds her legs. Thankfully,

the repair machine still works and she

can use it to reconnect both halves of

her body, although the process will take

a while. She thanks Deck for his help,

but also apologizes and tells him to

leave because she's activated the beacon

to call her crew. Thea explains her team

is also after the call, so she can't let

him kill it. Deck refuses to leave,

saying he'd rather go down with honor

than run like a coward. In the middle of

the wreckage, there's some spilled oil,

so Deck sets it on fire to create a

smoke cloud. The callusk soon appears

and throws Deck down, damaging his

sword. Deck uses a piece of metal as a

shield and slides under the callusk to

slice its belly. Then he throws his

small blade at its head and cuts its

tail. However, the tail quickly regrows

and the wounds close because the callus

has regenerative powers, which explains

why it's considered unkillable. The

monster captures Deck and throws it

against the repair machine, which causes

Thea's legs to fall off the table. When

it grabs him again, Dell cuts its tongue

to free himself. The fight continues and

Deck has to dodge several attacks while

Thea tries to retrieve her legs. At that

moment, she sees a gun on the ground and

opens fire at the call to distract it.

Deck uses the chance to throw a chain at

the call's mouth and activates a machine

that starts rolling up the chain, which

drags the beast back. Next, Deck takes

Thea's gun and starts shooting. When the

monster attacks him with its tail, Deck

dodges it and closes a storage unit door

to trap it. Now, he can run up the

call's body and make a big jump above

its head to successfully decapitate it.

Sadly, this is still not enough to kill

it, and the head quickly reattaches

itself to the body. The callusk holds

Deck down with its hug paw and sniffs

it. The smell it finds prevents it from

attacking. The moment is interrupted

when Tessa throws a grenade to freeze

both Deck and the callusk so she can

capture them. Sometime later, Deck wakes

up strapped to a table in the crew's

vehicle. Thea is in suspension mode

because she's connected to the repair

machine, and Tessa has read all her

logs. She doesn't understand why Deck's

alive since the Yaya usually kill weak

children and says that belonging to her

company should be an honor for him. Then

Tessa wakes up Thea and congratulates

her for getting two specimens. She gives

Deck a painful injection to experiment

on him. So Thea tries to smoothly save

him by pointing out he's a rut and

therefore not ideal for science. She

thinks they should keep his weapons and

let Deck go. Tessa still wants a sample,

so she connects two cables to his head

that cause him lots of pain. A desperate

Thea turns off the machine and tells

Tessa they should be more than robots

that only follow orders. In fact, she

wants them to be sisters. However, Tessa

reveals she didn't come back to rescue

Thea. She came for the callusk. She

agrees with Yaoya's tradition of getting

rid of the weak and calls Thea broken.

At that moment, Tessa gets a call from

Earth. So, she leaves to take it after

ordering a guard to box Thea up. Since

the guy can't speak Ya, Deck asks Thea

to make him open one of his devices.

Thea tells the guard that Deck's device

is a map, and when he opens it, his head

explodes. Then, Thea frees Deck an alarm

is triggered, so more guards come to

open fire at him. Thea opens the back

door, and Deck jumps into a waterfall to

escape. Sometime later, Deck finds his

crashed ship and takes care of his

wounds. However, there are no weapons

left. He considers leaving the planet,

but he looks at his brother's helmet and

remembers that the best wolf is the one

who protects the pack. Deck returns to

the jungle and starts gathering natural

dangers to use as weapons, like blades

of razor glass and the spikes from the

red flowers. He also gets the acid worm

by using the fruit. While working, he

comes across Bud and smells its spit. He

finally realizes that Bud is the call's

child and he was spared for smelling

like it, so Deck covers Bud with his own

spit instead. Lastly, he frees Thea's

legs so he can follow them to their

owner. At the new base, Deck appears

wearing the bison bones as armor and

throws acid at a guard to bring him

down. The legs follow a signal from

Thea, who is in suspension inside a box.

When two guards try to attack the legs,

Deck quickly defeats them with a whip

made with vines and razor grass. Bud

also helps by destroying a guard in

seconds. The duo keep sneaking around

the base, bringing down any guard in the

way so the legs can keep moving without

interruptions. Meanwhile, Tessa is

talking to the company and reports

they'll go back soon with the callusk.

When asked about Deck, she tells them

that he's dead. With his collection of

natural weapons, Deck keeps destroying

synthetic guards, sometimes fighting a

few of them at the same time. Inside a

lab, a guard manages to corner him, so

Deck breaks a glass cage and lets a vine

sample kill him instead. When the legs

find the box, they jump on a guard's

neck and quickly kill him before opening

the container. Thea awakes and

celebrates, but she hears guards coming,

so she pretends to be asleep again. The

legs kick a guard to make him fall, and

Thea jumps out to fight him while the

legs confront the second guy. Both body

halves help each other in battle. And

when a guard is about to hit the legs,

they jump away and the blow destroys the

other synthetic who is being held by

Thea. Then she holds up a small machine

piece and the legs push the final

guard's head on it to kill him, too.

Soon, Deck finds the box, too, but it's

empty. A guard surprises him from

behind, only for Thea to kill him with a

shot. Her halves are finally back

together, and she's surprised to see

Deck, who admits he came back for her

like a proud wolf. Thea wants to leave,

but Deck announces they must free the

callus so Bud can be with its mother.

Suddenly, an alarm goes off, and Tessa

tells her men to speed up the launch of

the ship with the callus. While she

investigates, a team of soldiers finds

Deck, who activates the combustible

worms to create a nice explosion that

destroys all the synthetics in one go.

Then, Tessa appears inside a battling

suit and shoots Deck with a laser she

stole from his ship, which kills his

acid worm. She uses the suit to bring

down structures and pulls out a huge

saw, but Deck dodges it all. In the main

ship, Thea tries to access the callus,

but the cage is locked. When a guard

comes by, she fails to impersonate

Tessa, so she smashes the guy's head on

the cage instead. Then she uses his eyes

to open the lock. When an attack throws

Deck into the lab, the suit hand comes

down and is captured by the moving vine.

Deck tries to climb it, but Tessa

immediately throws him off, so he hides

behind a container. Tessa lifts it, but

doesn't see him. It turns out he's

climbed on the container to be above

her. Now Deck can jump on Tessa to beat

her up, but she quickly closes the

cockpit. Suddenly, the callus appears

and jumps on the suit, so Tessa

activates the saw to stab it and lift

it. While she's distracted, Deck climbs

to the back of the suit and starts

ripping cables off to slow it down.

Tessa throws a grenade at the callusk,

but Deck hits it with a metal rod and

makes it land on the suit's arm, so the

ice makes it drop the callusk. The beast

removes the saw from its body and

attacks the suit, splitting it in two.

When the upper half lands, the callus

devours Tessa and roars in victory. The

others reunite with Deck, and they watch

the callusk check on its kid. They share

a sweet moment and Deck is inspired to

show his respect for the callus too by

bumping foreheads. Suddenly, the callusk

explodes from an ice grenade activated

by Tessa, who has been alive inside the

beast's stomach. She emerges from the

rubble and tries to attack Thea, only

for Deck to stab her from behind,

finally killing her. He takes back his

device, and Bud rips off her head.

Sometime later, Deck returns to Ya and

presents Tessa's head to his father. Nar

still thinks he's a disgrace and sends

out two guards to kill him, but Deck

moves fast and easily kills them first.

Then Deck fights Jar, who hides with his

camouflage cloak. Deck activates the

ship's engine to create a sandstorm that

allows him to see his father's location

and cuts his arm off to stop him. Then

he captures him with a cage device. When

Deck symbolically stabs his dad's

helmet, Jar takes it off and says that

Dell can join the clan if he shields.

However, Dell says he already has a clan

before a grown-up butt eats Injar's

head. Thea congratulates him while Deck

takes his father's cloak. At that

moment, another ship appears and Deck

says it's his mother. Make sure to
