It never occurs to Trevor that dishy blondes don't usually sell jazz records door-to-door. He orders a set of Bix Beiderbecke LPs but receives the wrong items. While trying to locate the missing music, he and his girlfriend, Jill, stumble upon black market goods in a church basement, secret meetings in a parking lot. They find corruption at the highest levels. Helping them out are a couple of friends, an overzealous police officer, an elderly snoop, and a town planner with a drawer full of incriminating files.
