A sixth convict, the wealthy Jack Tar (James Tien), is released on the same day. Upon his release, he commences work on his next criminal project: trading counterfeit US and Hong Kong currency with an American crime boss. Jack sends his chauffeur to do the exchange at a skating competition, but the chauffeur's insecure attitude attracts the attention of two muggers. The muggers steal the briefcase containing the counterfeit US money and take off. Police officer CID 07 (Jackie Chan) attempts to recover the briefcase containing the phony money, but the case accidentally ends up in the Five Stars Cleaning Co. van. CID 07 continues his pursuit of the muggers, which results in a massive freeway pile-up.
