The Untouchables

During the era of Prohibition in the United States, Federal Agent Eliot Ness sets out to stop ruthless Chicago gangster Al Capone and, because of rampant corruption, assembles a small, hand-picked team to help him.
Young Treasury Agent Eliot Ness arrives in Chicago and is determined to take down Al Capone, but it's not going to be easy because Capone has the police in his pocket. Ness meets Jim Malone, a veteran patrolman and probably the most honorable one on the force. He asks Malone to help him get Capone, but Malone warns him that if he goes after Capone, he is going to war.
