The Scarface Mob

Based on the provided information, I believe the intended movie name is 'The Untouchables' and not 'The Scarface Mob'. Al Capone was indeed a 1920s' Chicago gangster who eventually got imprisoned. Here's the plot synopsis of 'The Untouchables': 'The Untouchables,' directed by Brian De Palma, is a 1987 American crime drama film that tells the story of Eliot Ness, a determined and ambitious Prohibition agent tasked with bringing down the infamous Al Capone, the notorious and ruthless Chicago gangster. Set against the backdrop of the Prohibition era in Chicago during the late 1920s, the film is based on the true story of Ness and his team of eight men handpicked to form 'The Untouchables,' a secret unit within the Prohibition Bureau that aimed to bring Capone to justice. The film opens in Chicago, 1930, where Al Capone has built an empire through violence and intimidation. Capone's empire spans from crime, smuggling, and murder to corruption of government officials. The federal government, aware of Capone's rise to power, decides to send Eliot Ness, at 29 years old a promising young Prohibition agent, to Chicago. Ness selects a team of experienced and fearless men to join him in his mission to bring Capone down. These men include Jimmy Malone, a veteran cop with experience in Chicago; Oscar Wallace, an accountant who helps Ness build his case against Capone; Walter Aubrey, a lawyer; Ed Miller, a tough and ambitious agent who is initially hesitant about joining Ness; George Pike, and Charles Hagan. Lastly, they hire George "Machine Gun" Kelly's protégé, George "Machine Gun" Kelly's cousin, or rather protégé, is incorrectly stated but George is the nephew of a local man, later revealed to be a cousin, named Mike, a gangster who later becomes an informant and the cousin of Al Capone's top aide, George 'Mushy' Bergan.
