A teenage boy wakes up in the desert, with his parachute dangling on a tree branch, before a giant black monster appears from the dust and approaches him. The monster attempts to consume him, but he releases himself from the parachute and runs away after discovering the monster is transparent. He follows a black road toward a cave, where he finds a motorcycle and a forest by the ocean. After eating and bathing in the forest, he meets a small yellow chick and finds a backpack filled with a survival kit and a map of the island he is on. The map shows him directions to the port village on the other side of the island. With the monster still standing in front of the cave, the boy spends the night in the forest. The next day, the boy takes the motorcycle and circles around the cave when a flock of white birds appear in the sky, causing the chick to follow the flock and get swallowed by the monster before the boy runs through the monster and rescues it. That night, he stocks up on fruits and water and rides with the chick out of the cave. Following the arches ahead of them, they cross the desert into the grasslands, with the monster slowly following them and consuming every animal on its path. The boy climbs a mountain decorated with
balancing rocks and pushes a boulder down toward a wooden bridge while a white fox appears and chases the chick. He manages to destroy the bridge and send the monster falling, but the chick also falls off the cliff before a white bird guides it back to the boy. In the middle of the journey, the chick spreads its wings and bids farewell to the boy as it joins a flock of white birds. That night, the boy has a dream of himself parachuting from a plane while being surrounded by black human-like figures resembling the monster falling to their deaths. Meanwhile, the chick and the flock circle back to the bridge to discover the monster still alive and continuing its pursuit of the boy. Days later, the boy stops and discovers the wreckage of the plane he was on several days ago. As he seeks shelter in the fuselage from the rain, the flock continues to follow the monster when all the white birds suddenly die and fall toward the monster, leaving the chick to fly to the boy and warn him of the monster's approach. The next morning, the boy walks his motorcycle on steep inclines through snow-capped mountains with the monster tailing him. As the blizzard intensifies, he passes out from exhaustion before the monster consumes him. He finds himself falling deep inside the monster before the chick arrives and pulls him out and the monster explodes. The boy wakes up and he and the chick race downhill against an avalanche toward the port village. The boy rides the motorcycle down into the ocean to avoid the avalanche and swims to shore. After removing his goggles, he sees villagers walking toward him in the distance, the white bird flying above them. == Release ==
