A thrill from start to finish

Rating: 10/10 (11 May 2014)

Boy, what an awesome plot. So for those who are confused, and I know there are some, here it is: Frank Costello (Jack Nicholson) is the leader of the mob in Boston. His protégé, Colin Sullivan (Matt Damon), becomes a Mass. State Trooper in order to work as a mole in the force for Costello. Cpt. Quellan (Martin Sheen) and Sgt. Dignam (Mark Wahlberg) begin to develop the theory that there may be a rat working for Costello. So, they enlist former cop-trainee Billy Costigan (Leonardo DiCaprio) to go undercover and infiltrate Costello's gang. Billy succeeds and Costello welcomes him. Meanwhile, Sullivan is put in charge of finding out who the rat is (NOBODY KNOWS HE IS LOOKING FOR HIMSELF). And Quellan and Dignam inform Costigan that he needs to find out who the rat in the police department is. As the movie intensifies, Costello understands that he has a rat in his gang. Costigan convinces Costello that he is not the rat, and Costello believes him. On the side of all this, Costigan nails Sullivan's fiancée. Now for the Climax: Costello's men throw Cpt. Quellan off the roof to his death. Then, Sullivan learns that Costello talks with the FBI, so he kills him. Sullivan is heralded as a hero around the office, but is still aware that Costigan, who appears at the station, isn't good news. Costigan, via looking at a very important envelope on Sullivan's desk, learns that Sullivan is the rat. Sullivan, simultaneously, learns that Costigan was Costello's rat. Costigan hunts down Sullivan, but is shot dead by Sullivan's men. The movie ends with Sgt. Dignam waiting in Sullivan's apartment. BANG. Sullivan is killed, and Dignam walks out. The camera then focuses on a rat on the balcony. SUCH A FANTASTIC FILM. 10/10
