In the final installment of the Godfather Trilogy, an aging Don Michael Corleone seeks to legitimize his crime family's interests and remove himself from the violent underworld but is kept back by the ambitions of the young. While he attempts to link the Corleone's finances with the Vatican, Michael must deal with the machinations of a hungrier gangster seeking to upset the existing Mafioso order and a young protege's love affair with his daughter.
