Untouchables, The (1987)

An account of the battle between gangster Al Capone and lawman Eliot Ness, a federal agent who has come to Chicago during the Prohibition Era when corruption in the local police department is rampant. To combat the powerful and popular Capone, Ness puts together an unlikely team: a veteran patrolman, a gunslinger rookie, and a nebbish accountant -- The Untouchables -- who doggedly pursue Capone and his illegal interests.
