A follow up of sorts to his earlier film, the seminal Caliber 9 (1972), Blood and Diamonds (1977) blasts its way into familiar poliziotteschi territory, leaving scars, bullets and tire tracks in its bloody wake. After being set up by the Mafia gang he is part of, Guido (Claudio Cassinelli) is sent to prison but upon he vows to take revenge on those who betrayed him.
