An Eastern potentate, the Rajah of Bandor (Charles Lung), and his American bride (Sue Casey), are robbed of a fortune in jewels on the Riviera, by a quartet of thieves led by Otto Von Herzen (Stephen Bekassy). The gang flees to Hong Kong, followed by Charles Reeves (Robin Hughes), British insurance investigator, and his sister, Susan (‘Lois Hall’ )qv)). Bill Whitfield (Warren Douglas), a none-too-bright American entrepreneur, gets involved with Stella Strutzenbacher (June Vincent), a flashy and stylish member of Herr Von Herzen’s gang. The gang, already riddled with dissension, are easy pickings for Whitfield, Charles and Susan to capture and recover the Rajah’s jewels.
