Angelo Lagusa witnessed a tragedy as a boy growing up in the village of Lawless: his parents and younger brother were brutally murdered by the Vanetti mafia family. He abandons his name and hometown, adopting the new identity of Avilio Bruno, after losing all he holds dear. When Avilio receives a mystery letter motivating him to return to Lawless seven years later, he finally has his opportunity for vengeance. Obligingly, he soon finds the Vanetti don's son, Nero, and uses the talents he has silently nurtured for years to befriend him. 91 Days is a film set during the Prohibition era that chronicles the narrative of Avilio's terrible, bloodstained quest to vengeance as he systematically eliminates each of the individuals responsible for the murder of his father.
