Three years after the events of The Godfather, Michael Coreleone has moved his family to Las Vegas, leaving Don Trapani as his proxy in New York. Michael ultimately intends to go legit, passing the torch of his criminal enterprises onto Trapani, and allowing his trusted capo-regimes to form their own families, should they desire. When Trapani is assassinated, his top enforcer, Dominic, steps in to fill his shoes. Backed by a crew of capable henchmen, Dominic is tasked with defending, and expanding, Corleone interests in New York, Miami, and Havana. However, Michael's plans for legitimacy and Dominic's greater ambitions are both threatened by a bloody turf war with the Rosato brothers, a Senate investigation into organized crime, the betrayal of business associate Hyman Roth, and Fidel Castro's revolution in Cuba.
