Plot
Conceptual artist Anne Benton creates electronic pieces that flash evocative statements, and her work has begun to attract major media attention. One night, while driving home, Anne suffers a blowout on a road near some isolated industrial factories. While looking for help, she witnesses a mafia hit supervised by Leo Carelli, who kills another mobster and his bodyguard. Leo spots Anne, but she manages to escape and goes to the police.
Two of the mobsters, Greek and Pinella, go to Anne's house to silence her but end up killing her boyfriend, Bob. FBI agent Pauling, who has been after Carelli for some time, offers Anne a place in the Witness Protection Program. However, when she sees another mobster, Carelli's lawyer John Luponi, at the police station, she disguises herself with another woman's wig and raincoat and flees. Meanwhile, mob boss Lino Avoca, Carelli's boss, summons top-of-the-line hitman Milo to silence Anne. Milo purchases one of Anne's artworks and ransacks her house, discovering intimate Polaroids taken of her.
Months pass, and Anne has severed all ties with her past, re-establishing herself in Seattle as an advertising copywriter. Milo, relentless in his pursuit, recognizes the tagline of a lipstick ad as one of Anne's catchphrases and tracks her down. Pauling and the police also track Anne down, but she manages to once again elude all the men pursuing her. Milo eventually tracks Anne to New Mexico, where he is followed by Pinella, who is tracking Milo's whereabouts for Carelli. Milo quickly kills Pinella, corners Anne, and offers her a deal: he'll let her live if she does anything and everything he asks. Milo's interest in Anne goes beyond professional, but not exactly as she thinks; he doesn't want her to be his sex slave, although sex is part of the equation.
Obsessed, Milo has fallen in love with Anne, and he has no idea how to cope with the unfamiliar emotion. Surprisingly, after a rocky start, Anne realizes that she has also fallen for him. At the same time, failing to kill Anne as hired, Milo has marked himself for death. Anne and Milo flee together to an isolated farm that Milo owns. Avoca's men track them there, and they narrowly escape.
Anne and Milo realize that to be free, they must return and confront their pursuers. They concoct a plan, leaving Avoca, Carelli, and all of their men dead. Anne and Milo escape together to a new life, presumably in France.
