Basic Instinct 2 (2006) PAL DVD9

The decadent life of novelist Catherine Tramell continues in this sequel that finds her in the opening sequence speeding through the streets of London using the hand of her obviously under-the-influence soccer-star boyfriend to masturbate herself. After the car goes out of control, she manages to escape but he drowns leading to an investigation of whether she had in fact murdered him with an implication that he was already dead before the car even entered the water. Officials bring in a police psychologist to determine her mental state. Obsession sets in and the psychiatrist is drawn into her manipulations and dangerous world. As deaths occur around the pair involving acquaintances of both parties, including the psychiatrist's ex-wife, the story twists (and doesn't answer) to make you wonder who is committing the crimes.
