Inspector Wears a Skirt meets Ghostbusters meets Falling Down in this mad-cap police comedy directed by Yuen Cheung-yan featuring workplace violence and demonic possession. The Hong Kong police force has hit upon some financial hard times and its cowardly superintendent has hit upon a splendid way of dispensing with unwanted help without actually going through the ordeal of firing them -- taunt and abuse them 'til they quit. Yet the plan horribly backfires when in the midst of the hazing, the officers accidentally raise a malicious female spirit who promptly possesses the entire male population of the force. Though a Taoist priest expels the spirit from the men, it immediately possesses a policewoman named May (Lau Yuk-ting), who takes machine gun in hand and goes postal on one and all. The film ends with prolonged grieving process and an answer to whether or not there are actually any vampires in this movie.
