We are in Rome in 1958, the year recalled for the Merlin law, which marks the end of the closed houses. The criminal from the “code of honor“ Arturo La Paglia, called “Mister“ (Gabriel Garko) wants to mark his last shot, the robbery of the century, then to live happy with his Anna Rosi (Asia Silver) young prostitute with two children: Antonia (Manuela Arcuri) and Sergio (Raniero Monaco of Lapio). However, Man did not take into account the wickedness and ruthlessness of his accomplice, Gianni Fontana (Bruno Eyron), who, overwhelmed by debts with Vito Cirasola (Luigi Maria Burruano) and Bellafaccia (Brando Giorgi), wants the whole booty of the robbery.
