The story revolves around a Basque Roman Catholic priest dedicated to committing as many sins as possible, a death metal salesman from Carabanchel, and the Italian host of a TV show on the occult. These go on a literal "trip" through Christmas-time Madrid to hunt for and prevent the reincarnation of the Antichrist.
Three stories intertwined which occur in a single day. The day Ines discovers she is pregnant, Antonia decides to abandon her family and Marian realizes she is going to die.
