Description: This gritty crime drama from director Martin Scorsese takes us into the lives of two cops: Colin Sullivan (Matt Damon), smart and unabashedly ambitious, appears to be on the fast track in the Massachusetts State Police Department's elite Special Investigations Unit, whose prime target is powerful Irish mob boss Frank Costello (Jack Nicholson). Billy Costigan (Leonardo DiCaprio), street-smart and tough, is purported to have a violent temper that costs him his badge and eventually lands him back on the rough streets of South Boston, where he is recruited into Costello's ranks. But neither man is what he seems and, as they work at cross purposes, they are plunged into a dangerous game of cat and mouse in which the stakes could not be higher. [Warner Bros.]
