Only a policeman could write such a truthful story about police officers. Five friends strike up a friendship in 1995 at the National Police School in Ávila, Spain. Throughout their careers, they face various challenges and dilemmas that lead them down complicated paths, both personally and professionally. After twenty years of service, they reunite in Huesca, where one of them asks an extreme favor from his comrades: he asks for help to dispose of a body he has in the trunk of his car. Sometimes camaraderie can lead to decisions that challenge ethics and the law.
