In Hong Kong, Inspector Ng manages to stop the theft of an armored car by a group of criminals. In another part of the city, a deal is being made between a Westerner and an assassin. After the deal goes sour, the assassin kills the Westerner while the duo of Asprin and Strepsil enter to pickpocket the Westerner and steal his passport. Unknown to all of them, the Westerner had secret microfilm that contained details of a group of criminals involved in illegal activities, most notably the crooked businessman Mr. Tin. Inspector Ng arrives later and is heartbroken to discover that the dead man was Richard Nornen, with whom she was romantically involved.
