An ordinary woman is driven to the point of violent revenge in this tense thriller. Karen McCann (Sally Field) is a suburban wife and working mother with two daughters. Karen's life is turned upside down when her 17-year-old daughter is raped and murdered, a crime she overhears on her cellular phone. Sgt. Denillo (Joe Mantegna), a bright and resourceful police detective, soon tracks down the culprit, an especially sleazy criminal named Robert Doob (Kiefer Sutherland). However, due to a minor technicality, Doob escapes conviction, even though he's clearly guilty. Karen's husband Mack (Ed Harris) suppresses his grief and tries to go on with his life, but Karen doesn't find this quite so easy; she joins a support group for parents of murdered children, and she discovers that within the group is an underground society that seeks vigilante justice against killers who've slipped through the net of the judicial system. Karen buys a gun, learns how to use it, and begins training in martial arts. She starts keeping tabs on Doob, and learns that he not only intends to kill again, he's targeting her younger daughter. Beverly D'Angelo co-stars as Karen's best friend Dolly, and Philip Baker Hall plays Sidney Hughes.
