Wai is a waiter in a country club. One day at work, he is humiliated by the wife of a millionaire Harry Tse; in order to get even, he and his gang plan to kidnap Mrs. Tse. His gang includes Jacky Chong, Sly Sze and Martha. The kidnapping goes wrong from the beginning. Instead of getting Mrs. Tse, they kidnap Harry Tse by mistake! The police send Inspector Mina Ho to investigate who suspects Wai is one of the kidnappers. Mina also asks Mrs. Tse to cooperate with the police, but Mrs. Tse refuses. On the other hand, Wai and the others do not know how to get the ransom money. Harry, in fact, helps them to devise a plan since he's afraid they might do something nasty to him if they don't get the money. (Source: TMDB)
