Jimmy Quinn and Walter Spencer bootlegged booze and stole cars for New York gangsters in the 1920s. Jimmy "retired" to open a speakeasy. Spence married the beautiful Flora Pennyweight, of Pennyweight Petroleum and moved into the family's New Jersey mansion.

In March, 1932, when the Lindbergh baby is kidnapped, Spence asks Jimmy to guard his wife and new son while he flies off in the company Tri-Motor to tend to new oil wells in Louisiana. Flora is sure their son is the kidnappers' next victim. Jimmy reluctantly agrees. At the same time he has to deal with two Connies-Connie Halloran who should be waiting in his room at the Chelsea Hotel but has gone missing, and Connie Nix, the pretty maid at the Pennyweight mansion.
