Chung Siu-hung directs this notoriously gruesome Category III flick. Jade (Elizabeth Lee Mei-fung) is the long-suffering wife of Sam Wong (Anthony Wong Chau-sang), a sociopathic white-collar worker who regularly abuses her in a variety of horrific ways. One night, after raping and torturing her, Sam's after-work entertainment is interrupted by cop "Fire Ball" Lee (Danny Lee Sau-yin) who proceeds to beat the stuffing out of him before throwing him in the clink. Sam soon leaves jail a free man because Jade is too scared to press charges. Concerned for her livelihood, Lee has Jade and their son move in with him. When Sam threatens to kill her aged mother, Jade returns home where she gets raped again and chained to the wall. Sam then goes over to Lee's girlfriend's place and rapes and beats her, sending her into a coma. Jade finally decides to take matters into her own hands and starts to plot revenge.
