Three bored young people from a middle class background, Lucia, Charly and Chino, turn to petty crime for kicks. But Charly is caught and sent to prison. During this time Lucia starts drug dealing while Chino joins the police. When Charly is released, he allows Lucia to lead him into further criminal activity. This creates a conflict of conscience for Chino: should he pursue his law-breaking friends, or quit his job.
