In this pre-WWII German mystery-comedy, a lovely kleptomaniac with a taste for fine jewelry is unable to resist temptation. Strangely, every time she steals something, a mysterious man pays for it. A clumsy detective begins investigating and finds a crucial clue: a strongly scented woman's glove. The perfume is an expensive scent and the detective's pal realizes that it belongs to a popular nightclub singer. The friend quickly becomes enamored of the girl, but then so does her mystery man, a notorious international criminal. Eventually he gets arrested, leaving the detective's pal to move in on the singer.
