The continuing saga of the Corleone crime family tells the story of a young Vito Corleone growing up in Sicily and in 1910s New York; and follows Michael Corleone in the 1950s as he attempts to expand the family business into Las Vegas, Hollywood and Cuba.

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.
