The Departed is a film in the infamous Scorsese and DiCaprio collaboration series they did for a couple years. I love this combination of artist, and they always come out with some brilliant; The Departed is no different. An adaptation of the screenplay by Alan Mak, and Felix Chong which was made into a film in 2002 called Internal Affairs. [Taken from IMDb] In South Boston, the state police force is waging war on Irish-American organized crime. Young undercover cop Billy Costigan is assigned to infiltrate the mob syndicate run by gangland chief Frank Costello. While Billy quickly gains Costello's confidence, Colin Sullivan, a hardened young criminal who has infiltrated the state police as an informer for the syndicate, is rising to a position of power in the Special Investigation Unit. Each man becomes deeply consumed by his double life, gathering information about the plans and counter-plans of the operations he has penetrated. But when it becomes clear to both the mob and the police that there's a mole in their midst, Billy and Colin are suddenly in danger of being caught and exposed to the enemy-and each must race to uncover the identity of the other man in time to save himself. But is either willing to turn on the friends and comrades they've made during their long stints undercover?
