Young Treasury Agent Elliot Ness arrives in Chicago and is deternimed to take down Al Capone but he learns that it's not going to be easy, because Capone has the police in his pocket. But Ness meets Jimmy Malone a veteran patrolman and probably the most honorable one in 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. They recruit academy cadet, George Stone and Treasury agent Oscar Wallace, who is also an accountant, who wants to prosecute Capone for tax evasion. When they make headway, Capone tries to get them but they are untouchable.
To look back at a movie after ten or so years and see how it looks then. That is a sign of true greatness. The best of movies are the ones remember, or talked about after 10, 20, 30, 40, or even 50 or more years. I believe that "The Untouchables" will be one of the movies that last at least 30 years, maybe more. Cause as of now, it's aged like wine.
