April 11, 1932. Millionaire building contractor Thomas B. Randall is the target of a kidnapping; he is throwing a party right now. Intruding on his estate that night are: ex-bootlegger and now gang leader George ""Blackie"" Dallas, Pete Appleby (former torpedo for the Purple Gang), Marty Stoke (bank heist expert) and Jiggs (ex-heavyweight boxer and now strongarm man). The gang kills a security guard, and kidnaps Randall-- and they warn his family and guests not to call the police, or he gets it.
