Someone is killing and raping young women. Glamour photographer Chan Ga Ming is wrongly accused and his cop friend, Jack, tries to find the real culprit. But Jack is hindered by the actions of his brutal boss, Inspector Lee, who is determined to charge Chan, by fair means or foul.
Chan's personal life is already in a mess. He is still working with ex-girlfriend Mary, who wants him to dump fiancee Pearl and come back to her. The accusation causes Pearl to break off the engagement.
One of the murders is witnessed by Pau, who aspires to model for Chan. The real murderer is a horrid, smiling villain who wears loud red jackets, and whose father is a wheelchair-bound gangster, who is friendly with Inspector Lee.
Most of the story concerns the efforts of Jack to clear Chan's name, with the help of Pearl and Pau.
