An experienced police detective (Roy Chiao), who has a gambling addict wife, is forced to work both sides of the law. He is teamed up with an eager young policeman (Wei Tung) and after some early awkwardness they begin to work well together. Everything is set up for a showdown with a serial killing swordsman (Shi Kwan-Yen)...
The film has plenty of goofy humour, though much of it is lost in translation especially with a badly dubbed film. Suddenly however, the tone changes abruptly with the search for the swordsman and much brutal violence and death. The fights are actually pretty good and innovative though the plot is a bit obvious.
