Cita mortal a l’Up & Down (2003)

Carvalho investigates the murder of a prison guard. While police focus on a young troublemaker who threatened the officer, Carvalho and Biscuter pursue a friend and former cellmate of the suspect, known as "el Navajas" ("the penknife"), a drug dealer at the Up & Down nightclub. The case escalates when "el Navajas" becomes the prime suspect in the cold-blooded murder of a young man from a wealthy family, also at the nightclub. Carvalho must locate the dealer before the police to prevent his client from receiving a life sentence.
