A truck driver "too lazy to work and too nervous to steal" gets mixed up in racketeering. Naturally his underhanded business practices make him a pillar of the community.
Charlie steps in to solve the murder of a wealthy American found dead in a London hotel. Settings include London, Nice, San Remo, Honolulu and Hong Kong. Fast-paced with lots of wisecracking. The first film to star Warner Oland as Charlie Chan.
