May 8, 1931. The special U.S. mail train, coming from Rock Island, is stopped by emergency flares on the tracks in Hillsdale, Illinois. Gangsters wearing Army gas masks lob tear gas grenades into the train; they shoot a postal clerk and make off with a million dollars in negotiable securities. 3 months later, ""Tough"" Tommy Karpeles, former big-time Chicago hoodlum, is arrested for complicity in the case; his 2 accomplices were not caught.
Chicago, March 1931. Eliot Ness and his men were doing raid after raid on Capone's speakeasies and breweries; his empire was tottering. Who would take over? A big-time gangster from New York, Charlie ""Pops"" Felcher, had just arrived in Chicago, along with his crooked lawyer Archie Grayson.
New York, 1931. While many people were unemployed and poor during the Depression, gangster-owned speakeasies and nightclubs created a new mobster aristocracy. One top mobster is Jack ""Legs"" Diamond -- known to the Underworld as ""the Clay Pigeon"" because of the many times he'd been shot at, and survived.
