The Spanish deep South, 1980. A series of brutal murders of adolescent girls in a remote and forgotten town bring together two disparate characters – both detectives in the homicide division – to investigate the cases. With deep divisions in their ideology, detectives Juan and Pedro must put aside their differences if they are to successfully hunt down a killer who for years has terrorized a community in the shadow of a general disregard for women rooted in a misogynistic past.

It tells the story of two young friends who must find a way for the president of the company in which they work (and father of one of them) safe return home, and that is enclosed strange circumstances naked in the trunk of his car.
