Carrie Ng Kar-lai stars in this gritty women-behind-bars flick directed by Raymond Leung Pan-hei. Withdrawn young lass Yuk (Season Ma Si-san) winds up in prison for six months after taking a drug possession rap for her no-good boyfriend. She is saved from notorious lesbian mobster "He-man" and her associates by Winnie Wong (Ng), a vicious street-hardened con who takes Yuk under her wing. In a series of flashbacks, it is learned that Winnie was a junkie prostitute who fell in love with an undercover cop. When his cover was blown and he was executed by the triads, she went on a crazed killing spree. Now the associates of the gangsters she killed are pressuring Yuk to rub her out.
