The series is about the day to day of a police station in a neighborhood south of Madrid. The cases investigated by police officers are less serious offenses, although they have a great impact on the lives of those affected: small conflicts of a social nature, with immigrants, evictions, or violence against women. With the police station as the center of the plot, it’s showing the characters, their problems, anxieties, hopes and joys.
Fresh off the Academy, talented rookie officer Alicia joins the police station in Distrito Sur. While she learns the ropes from veteran detective Miralles and streetwise agent Batista, she will try to find out the truth about her mother’s death.
