In 1863, Amsterdam Vallon returns to the Five Points of America to seek vengeance against the psychotic gangland kingpin, Bill the Butcher, who murdered his father years earlier. With an eager pickpocket by his side and a whole new army, Vallon fights his way to seek vengeance on the Butcher and restore peace in the area.

Based on the best selling autobiography by Irish expat Frank McCourt, Angela's Ashes follows the experiences of young Frankie and his family as they try against all odds to escape the poverty endemic in the slums of pre-war Limerick. The film opens with the family in Brooklyn, but following the death of one of Frankie's siblings, they return home, only to find the situation there even worse. Prejudice against Frankie's Northern Irish father makes his search for employment in the Republic difficult despite his having fought for the IRA, and when he does find money, he spends the money on drink.
