Tretje nadaljevanje znamenite družinske sage nas popelje v leto 1979. Michael Corleone se odpove nezakonitemu načinu življenja. Njegova hčerka Mary se zaplete v vroče razmerje z bratrancem Vincentom, nezakonskim sinom Michaelovega pokojnega brata Sonnyja. Michaelov sin Anthony se na očetovo ogorčenje noče pridružiti družinskemu poslu in ima za svoje življenje drugačne načrte. Kljub vsem naporom, da bi zaživeli novo življenje, don Corleone in njegov družinski klan preteklosti ne morejo ubežati...
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.
