Not a bad little mystery that spans the globe, from London to India, across the desert to Iran, then finally back to San Francisco. Someone has killed the detective hired by a suspicious father to investigate his daughter's fiance. Her "best friend" also is concerned over her well being. They get married anyway and flee to India. It's not long before he's cheating with a maid, in a rather prolonged scene filled with sexual innuendo. His wife flees with her friend to Iran. Scotland Yard is hot on the trail, and all roads lead to San Francisco, where Charlie Chan makes a brief appearance.
