Before the advent of mankind, other alien races were already exploring the rest of the
universe.
On the planet Somaris, Mills is watching his daughter Nevine play around on the beach while
he explains to his wife Alya that he's accepted a two-year exploration job.
Usually he does short runs, but this time he wants the extra money to pay for a treatment
for Nevine's sickness.
Then Mills teaches Nevine how to whistle with her hands before finally discussing the subject
of his trip with her too.
Sometime later, Mills is the pilot in charge of a ship that carries a crew in cryogenic
sleep.
One day, the ship encounters unexpected meteorite activity and gets hit multiple times by chunks
of meteorite.
As the ship begins coming apart, Mills rushes to the cockpit and sends an emergency signal
while guiding the ship to land on the nearest planet.
The ship ends up breaking up in two parts, and as Mills watches the inevitable crash,
he thinks about his daughter before falling unconscious.
Minutes later, Mills wakes up to hear the computer say they're in an unknown location.
He discovers he has a piece of metal stuck on his stomach, so he painfully removes it
to then cauterize the wound.
Next he puts on his astronaut suit and begins investigating the ship to determine the damage,
discovering the cryochamber is compromised.
After grabbing a laser gun just in case, Mills leaves the ship and walks into a pool of water
where a mysterious creature swims around him.
He also finds all the bodies of his crew and is devastated to notice none of them survived.
After checking the whole ship for damage and realizing the escape pod is on the other half
that landed somewhere else, Mills sends another SOS message saying he's on uncharted territory.
Feeling stuck and hopeless, Mills grabs his gun with the intention of ending things, but
memories of Nevine stop him from doing it.
Then Mills gathers all the tapes with the messages Nevine has been sending him just
to hear her voice again.
Suddenly the computer detects a working capsule nearby.
Mills rushes to investigate and is surprised to find passenger Koa is still alive inside,
so he immediately takes her out.
On their way back to the ship, Mills notices a huge paw print on the ground, which reveals
this planet is Earth sixty-five million years ago, meaning Mills is surrounded by dinosaurs.
The duo makes it to the ship when night falls, and Mills spends the night dreaming of Nevine
demanding to know where he is.
The next morning, Mills is determined to escape just to save the girl.
He uses the ship's computer to find the other half of the vessel, but the scan can't locate
it.
Afterward Mills goes outside to explore the area and discovers huge bones that indicate
how dangerous the local predators are.
He's also accidentally hit by a hot geyser blast, which he never saw before.
Once he recovers, he sees something shining in the distance and realizes the other ship
half is on a far mountain.
A quick scan confirms it, and when Mills begins to consider what path to take, he's suddenly
attacked by a small dinosaur.
After some struggle with the creature, Mills pushes it to the ground and hits it with his
gun until it's dead.
There are more noises coming from the woods, and when Mills goes to investigate, he discovers
Koa has left the ship.
The girl begins running as soon as she sees him, and Mills runs after her until they both
fall down a ledge where they find a big yet dead dinosaur.
Suddenly the trees start shaking and Mills sees an even bigger creature approaching,
so he grabs Koa and drags her back to the ship.
While he takes care of the wound she got when she fell, he tries to explain the situation,
but it turns out they don't speak the same language and the ship's translator isn't working.
To make his point, Mills spreads a red powder on a tablet and draws the mountain with the
pod to explain they must get there to escape.
Koa joins him and draws her parents as she understands the word "family", so to keep
her calm, Mills lies and says her family is in the mountain too.
Afterward, Mills sends out another SOS message saying he's found a survivor while Koa finds
the recordings of Nevine.
As she watches them all, it's revealed that during the first year of traveling, Nevine's
illness got worse and she had to be sent to the hospital.
During the first few months her messages were happy and proud of her dad, but as time passed,
she became angry with him because he wasn't there for her.
When Mills finds Koa watching the tapes, he immediately turns them off and announces they're
leaving.
Once he has enough supplies in his bag, Mills and Koa begin walking through the wilderness,
making sure to keep quiet not to attract predators.
It's a long and arduous journey, but every time Mills helps Koa when she falls or needs
anything, they become a little closer.
One afternoon Koa sees something glowing red in the sky, but she doesn't comment on it.
Eventually Koa becomes bored of all the walking and grabs some berries from a bush to throw
at Mills just to bother him.
Annoyed, Mills uses his scan to prove the berries are poisonous and orders Koa not to
mess with them.
Later, a huge bug lands on Mills' neck and when he kills it with his hand, his fingers
end up covered in a disgusting sticky substance.
Mills tries to brush it off on a tree, but the thing is so strong that he falls with
a piece of bark stuck to his hand, which makes Koa laugh.
To tease her back, Mills tries to touch her with his dirty hand, but their little game
is interrupted when a small tree falls in front of them.
There are some weird noises coming from behind a ledge, and the duo finds a small dinosaur
stuck in a pit of the sticky substance.
Koa feels bad for it and runs to help it out, which Mills thinks is too dangerous.
Since she won't listen, Mills ends up helping her to finish faster.
The little creature walks away as soon as it's free, but only a few steps later it's
attacked by a group of predators that quickly kill it.
Mills drags Koa into a hiding spot so she doesn't have to watch her friend being devoured,
but she can tell what's going on and cries.
After the dinosaurs are gone, the duo continues their journey, stopping by a waterfall to
wash and fill their water bottle.
Mills is worried about the state of his stomach wound, but watching Koa makes him think of
Nevine and that's enough incentive to keep him going.
Koa finds some pretty flowers and bothers Mills until he lets her put one in his hair.
Minutes later, Mills' scanner loses the location of the mountain, so he decides to climb a
tree for a better view and scan the area again.
Suddenly he finds a bug on his hand and shakes his arm to get it off, but the movement causes
the branch to break and Mills falls, dislocating his arm.
While Koa helps Mills push his arm against a tree to try to put it back into place, a
group of dinosaurs hears the noise and begins approaching.
To speed things up, Mills makes Koa step on his arm for that final push, and now that
he's better he immediately grabs the gun to shoot at the creatures.
He also tells Koa to run, and once she's far enough, Mills activates a few small bombs
that quickly gets rid of half of the dinosaurs.
The survivors continue to jump on Mills and he shoots them one by one.
Meanwhile a bunch of flying dinos lands near Koa, so she begins crawling away to hide behind
a tree.
Unfortunately the beasts from before find her and when they are about to jump on her,
Mills shows up and kills them all.
However there's one hiding that suddenly jumps on Koa from behind and drags her away with
its tail.
Mills quickly goes after them and scares the creature away with a shot.
Now Koa is too scared to continue or even be near him, thus Mills sits down and patiently
gives her some space.
When it's starting to get dark, Mills decides to whistle like he used to do for Nevine to
try to calm Koa down.
The trick works and Koa responds with her family's own method of whistling, finally
accepting to keep going.
After lots of walking, the duo makes it to a cave where they'll spend the night.
Mills sets up some sensors that will warn them of potential danger and uses his scanner
to look at the sky, which finally makes him notice the meteorite is nearby.
It's a small one though so he doesn't worry.
Koa suddenly distracts him by revealing she's brought one of Nevine's tapes with her, and
while Mills at first is angry, then he plays the tape because Nevine brings comfort to
both of them.
While Mills tries to sleep, he can't stop thinking about the day Alya contacted him
to tell him Nevine had died in the hospital, which makes him cry.
Later in the night, Mills is woken up by the sensors warning him of incoming danger.
When he checks on Koa, he discovers a bug has entered her mouth and he immediately uses
a tool to kill it, leaving Koa to cough out all the remains.
Then the sensors begin going crazy and at that moment, a huge dinosaur appears outside
the cave.
Mills shoots it a couple of times before he and Koa run through a small hole at the back
of the cave.
The duo immediately begins looking for a path out, unaware that a smaller dinosaur is following
them.
After lots of walking and going through narrow spaces, the duo is upset to discover they've
reached a dead end.
Mills finds a small space between two rocks and tries to dig to make it bigger, but after
a few hours he's barely made any progress and decides to give up.
When Koa notices, she becomes furious and demands to try again as she keeps saying "family",
so Mills tries to tell her they're dead, but she can't understand him.
Thinking that he lacks proper tools, Mills suddenly gets an idea: he uses a few bombs
to make the hole big enough for a kid, then gives Koa the rest of the bombs to be safe
while she explores.
Koa crawls through the narrow hole and confirms there's enough room on the other side, so
Mills tries to follow her.
Unfortunately the hole suddenly collapses, and Mills desperately yells in frustration
when he loses contact with Koa.
At that moment, Mills hears the dinosaur approaching, thus he grabs his gun and returns to the previous
cave, where he uses his scanner to know where the dinosaur is.
When the creature tries to attack him from behind, Mills expects it and begins shooting
it, but the dinosaur hits him and makes him drop the gun.
Then the beast grabs Mills and bites his arm, but Mills fights it off until he manages to
reach his scanner and activates a screeching sound that hurts the dinosaur's ears.
With the animal distracted, Mills retrieves his gun and kills it.
Meanwhile Koa makes it outside.
She explores the forest alone and finds a huge bone that she can use as a weapon, so
she wraps it up with poisonous berries and a big leaf before putting it away in the bag.
Minutes later, Mills manages to leave the cave and when he sees that a huge meteorite
is coming closer, he uses his scanner to learn that the meteorite he saw before had only
been a broken piece of a bigger one that will hit in a few hours, triggering a catastrophic
extinction event.
He immediately goes looking for Koa and hears her scream when a dinosaur approaches her.
Koa rushes to hide inside a tree trunk while Mills runs in her direction, but he trips
and falls right into a pit of quicksand.
He tries to call for Koa, but he slowly sinks until he can't talk anymore.
Koa hears Mills' call, so she gathers her courage and waits for the dinosaur to enter
the tree trunk to throw the bombs at it before running.
With the beast dead, Koa can safely reach the quicksand and bend over a tree to help
Mills come out of the pit.
The duo reunites with a tight hug and then Mills explains the meteorite to Koa in order
to run through the last few miles.
In the evening, the duo finally makes it to the base of the mountain.
Mills ties some rope around Koa and she starts climbing up first, then she smartly ties the
rope in a very intricate way around trees and rock so it'll stand Mills' weight as he
climbs up as well.
Moments later they find the other half of the ship, and Mills immediately turns on the
computer to confirm there's a rescue vessel coming for them.
Koa goes looking for her family and eventually finds all the destroyed cryotanks, so she
gets furious with Mills for the lie.
As she cries, Mills takes out a picture of Nevine and explains he lost his daughter while
he was on a job, meaning now he can't allow that to happen again.
A sobbing Koa hugs Mills as he apologizes for everything.
Suddenly the smaller pieces of meteorite begin falling on Earth, so Mills and Koa run to
get inside the emergency pod.
When Mills is about to push the launch button, a piece of meteorite hits the ship and causes
the pod to fall down the mountain, knocking the duo out in the process.
Koa wakes up first and quickly presses the launch button, but the computer explains it
can't launch in this position.
As Mills begins waking up too, a huge dinosaur arrives and begins attacking the pod.
Since the gun fell on the ground, Mills has to risk leaving the pod to retrieve it, only
to discover it doesn't work.
While a second dinosaur joins the attack, Mills runs to hide behind a piece of the ship
and fixes the gun configuration.
The dinosaurs suddenly surround him, so Koa grabs the Nevine tape and plays it on the
scanner to create a hologram of Nevine outside the ship.
Mills cries because he thinks he's getting to see his daughter one last time before his
death, but it turns out the dinosaurs are tricked and attack the hologram first.
Using this distraction, Mills comes out and quickly kills the first creature while the
other pushes the ship trying to reach Koa.
Mills immediately comes after it too and after a few well-landed shots, this dinosaur dies
as well.
Thanks to the creature's push, the pod is now in the right position to launch.
Before Mills can return though, the beast that he had shot back in the cave returns
and begins chasing him.
With a plan in mind, Mills runs to the geysers and makes the dinosaur walk into a hot blast
of water that hits its face.
Unfortunately it doesn't cause much damage, but at that moment Koa shows up and stabs
the dinosaur in the eye with the bone she prepared earlier.
The dinosaur starts flailing and walks on top of another geyser, this time the blast
hits it on the stomach and successfully burns it to death.
Afterward, Mills and Koa return to the pod and manage to take off right before the meteorite
hits Earth, triggering the extinction of dinosaurs.
When the pod leaves the atmosphere, the autopilot guides it to the meeting point where a rescue
vessel will be waiting for them.
Since they're going home, Mills closes his eyes and pretends he would be reuniting with
Nevine soon, so Koa holds his hand to comfort him.
