Naked Killer () is a 1992 Hong Kong erotic thriller film written and produced by Wong Jing, and directed by Clarence Fok Yiu-leung. The film stars Chingmy Yau, Simon Yam and Carrie Ng. The film is regarded as a cult classic. Plot Kitty is a vicious young woman who has no qualms about stabbing girlfriend-bullying men in the genitals. Tinam is a cop who is undergoing a traumatic period: he shot his own brother by accident, and as a result now vomits every time he handles his gun. When Kitty severely injures a man by stabbing him in the groin, Tinam attempts to arrest her but fails. Kitty later turns up at the police station and manipulates the facts to the point that Tinam has no choice but to start a relationship with her. Tinam, who has become impotent, finds that he no longer feels the same way about Kitty, who is content with leading him on. Kitty's father is married to a new wife but the marriage is tense. One evening he catches her cheating on him with another man called Bee. In the fight that follows, Kitty's father falls down the stairs and is killed. Furiously determined to seek revenge, Kitty breaks into Bee's office and proceeds to kill him, his bodyguards and most of his staff. In the course of her escape she takes a woman hostage but, unexpectedly, the woman helps her out, disposing of many of the pursuers herself. The woman turns out to be a professional assassin called Sister Cindy. She was out to kill Bee herself before Kitty intercepted. She proceeds to train Kitty and gives her a new identity. The training includes the killing of enraged, chained-up paedophiles in Sister Cindy's cellar. For her first mission, Kitty accompanies Sister Cindy and murders a member of the Japanese yakuza. This leads to a contract being placed on them and the assignment is entrusted to Princess, one of Sister Cindy's former protégés and a lesbian with an equally deadly young lover called Baby. While investigating the murder himself, Tinam goes to check up on an air hostess whom the victim met prior to his death. The witness is Vivian Shang, whom Tinam recognises as Kitty. She denies this but renews their relationship. Sister Cindy proceeds to murder other people who could connect Kitty to Vivian Shang, including Tinam's superior and a witness to the
