After a chance encounter, a Dubliner is stalked by a murderous facsimile of himself.

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.

When schoolteacher Kieran Johnson discovers that his father was not a French sailor (as he had been led to believe) but rather an Irish farmer, he looks to his mother for answers. When she refuses to provide any, Kieran travels to Ireland.
