The Wasteland (2021)

Diego is a boy who lives with his parents in a shack in the middle of nowhere. His mother, Lucía, is kind, while his father, Salvador, is stern and solemn. One evening, Diego's father tells him about a beast that follows a person around and feeds on their fear.

One day, the family finds a badly injured man in a boat. Salvador attempts to heal the man. The man wanders into the shack and picks up a rifle, pointing it at Diego and Lucía. A gunshot is heard, and the man is seen, shot in the head. While going through his belongings, they find a family portrait. That night, Diego's father tells him about his sister, who saw the beast at their home. Salvador, who cannot see the beast, tells Diego that if anyone spots it, their life becomes hopeless. Salvador decides to go find the man's family on his own.

Over the following days, Lucía sees a presence approaching the shack each night; Diego doesn't see it. His mother begins to act erratically and cuts off her hair. She tells Diego that the presence is outside and pushes him out, telling him the beast desires her. Diego forces his way back into the shack and finds his mother badly injured on the floor. He then sees the beast walking towards them. Diego eventually finds enough courage to face the beast; he picks up a gun and shoots at it. He then sets the shack on fire and drags his mother outside. He puts her in a wheelbarrow and wheels towards the river, only to find out that she has died. He floats her body down the river and walks purposefully away.
