Angie Dickinson plays the sexually unsatisfied, fortysomething wife who's the killer's first target, relaying her sexual fantasies to her psychiatrist Michael Caine before actually living one of them out after the film's celebrated cat-and-mouse sequence in a Manhattan art museum. The focus then switches to a murder witness De Palma's then-girlfriend Nancy Allen and Dickinson's grieving whiz-kid son Keith Gordon, who attempt to solve the murder while staying one step ahead or so they think of the crude detective Dennis Franz assigned to the case. Propelled by Pino Donaggio's lush and stimulating score, De Palma's visuals provide seductive counterpoint to his brashly candid dialogue, and the plot conceals its own implausibility with morbid thrills and intoxicating suspense. If you're not laughing at De Palma's shameless audacity, you're sure to be on the edge of your seat. --Jeff Shannon
