Imperio de los Malditos (1992)

On the day of his first communion, the boy Honorato is orphaned because the mafia murders his parents. Before dying, the father recommends that the son defend himself against whoever tries to harm him, so that over time he becomes a bloodthirsty and sadistic gunman, always accompanied by the ghost of his father. His fame bears in the ears of Rutilo, the boss of the central supply, who hires him to avenge the death of his son. Honorato fulfills the mission with luxury of violence and becomes a trusted man of the gangster.
