Martin Scorsese directs an all-star cast in this action-packed thriller set in Boston, where a long-simmering hostility between the police department and an Irish-American gang led by Costello (Academy Award winner Jack Nicholson--About Schmidt, Something's Gotta Give) is primed to explode. The fuse is lit when a gangster (Matt Damon--The Bourne Identity, The Bourne Supremacy) is chosen to infiltrate the police force--and a young cop (Leonardo DiCaprio--The Aviator, Titanic) goes undercover within the gang. Now, when the two moles uncover each other's identity, the battle begins. ]]>
