Percy is a young man from a middle-class background; he helps his family, has a stable job, and loves the "Universitario de Deportes" football team. Percy and his best friend Caradura meet other fans of the "U" and begin to meet without imagining that they would be founders of the football hooligan group Trinchera Norte and their lives would take different directions, especially for Percy, who becomes the leader of the football hooligan club under the alias of Misterio. His family problems cause him to turn to drugs and alcohol, which would end up destroying his life.
