The fiction focused on a group of
police officers in San Antonio, a fictitious neighborhood in
Madrid, originally following a trio of clumsy yet good-hearted police agents: Paco, Mariano and Lucas, overseen by Don Lorenzo Castro Riquelme. The "forbidden" love story between Lucas and Sara (Paco's daughter) was another of the main storylines of the series, later turned into a
love triangle with the addition of Aitor. Seasons six through eight of the series centered on a
lesbian relationship between officer María Jose "Pepa" Miranda Ramos and
forensic scientist Silvia Castro León. Season 8 ended with a finale, "Todos los planes de Lucas Fernández", that brought the
wedding of Pepa and Silvia, which resulted in a bloodbath and the tragic death of four main characters (Silvia, Montoya, Nelson and Quique). In season 9, dubbed as
Los hombres de Paco 66.6, the series jumped the shark again, taking a
supernatural turn by bringing Silvia back from the dead as a phantasmagorical apparition and pitting the lead characters against Satan. ==Episodes==
