Chicago, Summer 1931. Nick Acropolis is the new bookmaker in town, his territory is Illinois and the 6 surrounding states; he covers bets on horse racing, boxing matches, ball games, everything. By August, his operation is $2-million per month. And so Eliot Ness and his Untouchables are on the case; Enrico Rossi has a wiretap on one of Nick's betting parlors, run by Sully Hinds. Nick and his boys pay a visit to their bookkeeper, Louis Manzak, who is Nick's brother-in-law. Louis embezzled 200 grand of Nick's money, to make a side-bet on a boxing match, and lost.
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.
