1945 In the summer, Vito Corleone, the godfather of the American mafia Corleone family leader, held a grand wedding for his little daughter Connie. The godfather has three sons: Sonny, the grumpy and lecherous eldest son, Fred, the timid second son, and Mike, the youngest son who has just returned from naval service. Sonny is the godfather's right-hand man. Although Mike is smart and capable, he is not interested in his family's career.

The "godfather" is the leader of the mafia, but it is also the patron saint of many weak civilians and is deeply loved by people. He refused Sollozzo's request, which aggravated the contradiction with several other mafia families in new york.

On Christmas Eve, Sollozzo kidnapped tom hagen, the godfather's adopted son and family adviser, and sent someone to assassinate him. This is the second attack on the godfather in his life. The first attack was outlined in a few words in the movie, but it is described in the novel as follows: a young assassin rushed into the godfather's house with the determination to die and threw a bomb at him, so the godfather was injured and the assassin was killed at will.
