A cop sets out to find a man who has been delivering too much of a good thing in this offbeat comedy. Police detective Martinez (Jesus Ochoa) has been handed a most unusual case -- a number of local prostitutes have been murdered, and it's up to Martinez to bring in the killer. What makes the case truly unusual, though, is the manner of death; it seems the hookers all died as a result of having orgasms so powerful they were literally fatal. Teaming up with cultural anthropologist Onofre (Daniel Giménez Cacho), Martinez hits the streets looking for clues, and eventually gets some unexpected help from Father Gorkisolo (Santiago Segura), a priest with a unusually deep knowledge of sexual matters. Asesino en Serio was the first feature film from director Antonio Urrutia; noted Mexican filmmaker Guillermo del Toro served as executive producer.
Early morning in the oat fields of Carranco, Ramón runs into the dead body of his secret teenage love Adela. After he covers her naked body with his shirt, the gossip in town is that Ramón's girlfriend is been found murdered. Meanwhile, the Gitano (the gypsy) has left Carranco after a night of love and sex with Gabriela, suddenly interrupted by a flash light of an unknown bearer. That night at the local bar, where Justino, the town sheriff and other regular costumers discuss what should be done, La Amistad, pointing his flashlight to them shouts "el gitano murdered the girl". Marcelino, a bitter old man pushes Ramón to avenge his "girlfriend"'s murder. Now Ramón will have to prove to the people in his town that he's now a man or leave the town in shame.
