Golden Sand City is filled with brothels and casinos funded by drug lord Yim Kung Ho (evil Mr. Yem) and policed by the iron fist of his henchman Panther (Leopard Head). Vigilantes Inspector Big Dragon (Bruce Liang), Little Mouse, and Black Cat plan to bring Yum Kung Ho and his evil empire to its knees, but face fierce opposition in the deadly Panther, who has the stolen pearls sought after by Big Dragon and his new ally Mei Ling.

Super-accurate fortune teller Blind Chen informs four young policewomen that the same man, whom they'll soon meet, will incite her to suicide (first woman), rape her (second woman), break her head (third) and kill her (fourth). This man turns out to be their new boss, Inspector Bak Fei Hung. The reason these things are to happen is due to the angry spirit of a former Red Guard muscleman who has sworn revenge against some HK gang bosses and, unfortunately, Bak and his new recruits get in his way.
