A master thief is duped by lookalikes for James Bond and the Queen of England into stealing a valuable gem from a heavily guarded location then must help the police recover it.

King Kong (Samuel Hui), while vacationing in Paris, is kidnapped by a British agent called James (Jean Mersant), who wants to recover one of the stolen crown jewels, the Star of Fortune, supposedly at the request of the Queen of England. The jewel is hidden at the Hong Kong Police Headquarters and Kong will have to steal the jewel without his partner-in-crime, Detective Albert "Baldy" Au (Karl Maka), knowing. When James' devious intentions are later revealed and Baldy and his wife, Supt. Nancy Ho (Sylvia Chang) discovered Kong's heist, Kong finds himself at a crossroad.—Oliver Chu
