In San Francisco, two police inspectors are on the case when a rogue taxi driver, with the help of a rogue porter, manages to st eal the suitcase of an antiques collector before running down a cop, whose dying gesture is to shoot the cabbie dead. The inspectors discover that a statuette in the suitcase contains ******. Meanwhile, a psychopathic gangster, his malignant mentor and their dipsomaniac driver have the job of picking up the other ****** shipments, hidden in the luggage of unsuspecting travelers. All goes well until they attempt to retrieve the ****** stuffed in a Japanese doll. A little girl and her lovely young mother have the doll, but when the crooks take possession of it, they find that the ****** has mysteriously vanished.
