A fortune teller (Michael Hui), who gives pretentious forecasts, was investigated by a revenue agent (Leon Lai) for failing to pay his taxes. However, the teller's lucky break came when he received a blow to the head during a robbery attempt, resulting him in receiving psychic powers. Thus, hoping this would get the agent off his back, he uses his new-found powers to try to help the agent solve a drug smuggling case that has been plaguing the revenue service.
