Boston's south of Massachusetts underworld is extremely rampant, one of the largest groups being led by the Irish Mafia. To eliminate them, the police decided to send a police school graduate named Billy (Leonardo DiCaprio) to infiltrate their ranks and do undercover work. The officer's cynicism had already made Billy feel very uncomfortable. He had hoped to be a decent police officer, but under pressure, he also had to obey orders. After undergoing the baptism of burning, killing, and looting, he gained Frank's trust. At the same time, Colin, another police graduate, similarly earned meritorious service for searching for illicit gains and won the commendation of his superiors. He was preparing marriage affairs with a summer in the right place. In fact, he was Frank's inserted into the police as a pawn; two people colluded for personal gain. Both the police and bandits discovered the existence of ghosts, launching a game of cat and mouse from this point on.
