A newly-married couple discover a male corpse in a multi-storey car park at Stuttgart Airport. At first everything points to robbery and murder as the dead man has neither his passport nor his wallet with him. Through his parked car police commissioners in Stuttgart are able to establish the identity of the victim. A little later the commissioners approach the known pickpocket Fred Eisner at the airport. As they search him they find the wallet of the victim. Fred Eisner is arrested for murder, however he vehemently protests his innocence.
