The Godfather (1972)

Set in the year of 1945 in New York City, this movie centers on the family of Don Vito Corleone. His youngest son, Michael, who served as a Marine during World War II, unwillingly joins the Mafia. He then becomes involved in the endless cycle of violence, betrayal, and vengeance. As much as Michael tries to maintain a normal relationship between him and his wife, Kay, it would be a little difficult to do so, especially that he's drawn deeper into his family's business.
