Assistant D.A. David Corelli (David Caruso) is trapped between friendship and the law when the brutal murder of an important San Francisco millionaire points toward his former lover and college friend, Trina Gavin (Linda Fiorentino), a beautiful woman with a mysterious alter ego. As details of the murder victim's sexual escapades emerge, Corelli uncovers evidence that the victim was blackmailing a powerful politician with incriminating photographs. But as the crucial witnesses are systematically murdered and attempts on Corelli's life are made, the case assumes a paranoid veneer in which nothing is certain and no one can be trusted. Set against a backdrop of the immaculate mansions of the San Francisco wealthy with a decorative fetish for the ancient Far East and contrasted with a classic Friedkin chase scene through the city's Chinatown, JADE is a lush, dark, and suspenseful sexual thriller from the writer of BASIC INSTINCT that will keep the audience guessing until the very last scene.
