"The Godfather is the story of organized crime in the 1940's which revolves around the Corleone family. Don Vito Corleone is the head of a New York Mafia "family". Problems arise when a gangster supported by another Mafia family, Solozzo, announces his intentions to start selling drugs all over New York. Don Vito hates the idea of drugs as he is quite happy with his hotel and gambling business. Don is shot by Solozzo's men. Solozzo then kidnaps one of Don's advisors, Tom Hagen and tries to make him force Don's eldest son, Sonny to agree to sell drugs, but the plan goes wrong when Sollozzo finds out that Don Corleone is still alive."

"Late in 1945, army veteran Michael Corleone brings his fiancee Kay Adams to meet his family on his sister's wedding day. His family, however, is a little different from most families.

His father is Don Vito Corleone, a powerful Mafia boss known as "the Godfather." His brothers Sonny and Fredo are soldiers in the organization and Sonny is the most feared enforcer in New York. His adopted brother Tom Hagen is the lawyer who handles the financial details of the family business. Scattered around the wedding reception are such luminaries as legendary hit man Luca Brasi, world-famous singer Johnny Fontane, and Mafia capo Dominic Clemenza.

After the reception, Don Vito, Sonny, and Tom, meet with Virgil Sollozzo, a drug smuggler who wants them to become partners in his business. Though Sollozzo offers attractive terms, Don Vito declines the offer.

When, a few days later, the Don is cut-down and seriously wounded by a pair of assassins, the violent Sonny is tapped to take the reigns of the family and vows to avenge his father.

In the midst of the resultant gang-war, "college-boy" Michael volunteers to kill Sollozzo and Captain McCluskey, his police protection. Meeting with the two in a small restaurant, Michael slays them both with a hidden pistol.

While Michael heads to exile in Sicily, Sonny continues the gang-war, now battling both the other five New York families and the police. When Sonny dies in a hail of gunfire, Don Vito returns from his convalescence to forge a new peace with the other families and even manages to arrange for someone else to be convicted of the murders Michael committed, allowing his youngest son to come home.

When the Don is finally felled by a heart attack and Fredo is sent to consolidate the family's power in Las Vegas, Michael is called upon to take control of the family business and take revenge on his enemies."
