Part I: "Don" Vito Corleone is the head of a New York mafia 'family.' His beloved son Michael has just come home from the war, but does not intend to become part of his father's business. Not given a choice, the business of the family is just like the head of the family, kind and benevolent to those who give respect, but gives in to ruthless violence whenever anything stands against the good of the family. An up and coming rival of the Corleone family wants to start selling drugs in New York, and needs the Don's influence to further his plan. A clash of old world values and the new ways will exact a terrible price, especially from Michael. Part II: Continues the saga of the Corleone family, tracing the rise of Don Vito as a young man in Italy, and that of Michael as the new Don, reigning from his Lake Tahoe estate. Part III: In the final instalment 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 protoge's love affair with his daughter.
