>Plot of Godfather III:

>As Michael Corleone (Al Pacino) ages, he finds that being the head of the Corleone crime family isn't getting any easier. He wants his family out of the Mafia, but the mob kingpin (Eli Wallach) isn't eager to let one of the most powerful and wealthy families go legit. Making matters even worse is Michael's nephew, Vincent (Andy Garcia). Not only does Vincent want a piece of the Corleone family's criminal empire, but he also wants Michael's daughter, Mary (Sofia Coppola).

Someone wants out of the mafia. An insider, probably high level on one side of the triangle grew a conscience. My guess is someone from SA, since that’s where the collapse started.
