Kevin Costner stars as Eliot Ness, an idealistic Treasury official who vows to bring an end to Al Capone's (Robert De Niro) corrupt hold over Prohibition-era Chicago. To this end, Ness puts together an elite team of law-enforcement officers (played by Sean Connery, Andy Garcia and Charles Martin Smith), and begins making bold strikes at Capone's bootlegging operation. Nevertheless, Capone's empire continues to thrive, and Ness realises that he must try a different approach. Brian de Palma directs, from a David Mamet screenplay, and Sean Connery won a Best Supporting Actor Oscar for his efforts.
