In April 2018, 9-year-old Nico is tormented by bullies who force him to steal an X-rated magazine from a convenience store, and tell him about a man who was shot and killed there 10 years earlier. Nico is caught shoplifting by the owner, Héctor, who realizes the magazine is not for such a young boy. Héctor does not tell Nico's mother, Lucía, and Nico instead buys a video game magazine. Later, he discovers a note saying he must not go to the store on his birthday, 12 April, or else he will be killed. When his mother complains to the school principal, Nico is bullied further.
