Bridget Gregory is a brilliant, ruthless, and completely sociopathic corporate executive living in New York City. Tired of playing by the rules and feeling constrained by her naive, earnest doctor husband, Clay, Bridget hatches a calculated scheme. When Clay makes a fortune of seven hundred thousand dollars from an illicit medical drug deal, Bridget steals the cash, empties their joint bank accounts, and abandons him without a backward glance, fleeing westward to escape his pursuit.Seeking a temporary hideout, Bridget arrives in the small, dusty town of South Egremont, New York. Stranded with a broken car, she meets Mike Swale, an unassuming, honest local insurance salesman. Sensing an easy mark, Bridget quickly manipulates Mike into a passionate affair, crafting a
false identity and spinning a web of lies about her
abusive husband who is supposedly tracking her down. Infatuated and desperate to prove his masculinity, the gullible Mike falls completely under her spell, blindly offering her his devotion, his savings, and a place to stay.Meanwhile, a frantic and humiliated Clay hires a private investigator to track Bridget across state lines. When the detective finally catches up to her, Bridget uses her seductive wiles and icy intellect to turn the tables, manipulating the investigator into revealing his employers and ultimately turning him away empty-handed. However, Clay refuses to give up easily and eventually traces Bridget to her new small-town refuge, determined to reclaim his stolen money and restore his ruined reputation.Realizing that Clay poses an active threat to her newfound freedom and stolen fortune, Bridget escalates her psychological game. She plays the two men against each other, convincing the blindly loyal Mike that Clay is a violent stalker who must be eliminated for their future together. Driven by misplaced chivalry and manipulated desire, Mike agrees to murder Clay. However, Bridget orchestrates the setup so that Mike actually pulls the trigger, making him take the full legal and moral blame for the homicide while she carefully cleanses the scene of her own involvement.In the brilliant, cynical conclusion, Bridget outsmarts everyone. She visits a bewildered Mike in jail, coldly cutting ties and leaving him to face a murder charge while she walks away a free woman. With Clay dead, the detective thwarted, and Mike imprisoned for a crime he committed out of love, Bridget boards a train out of town. Armed with the stolen seven hundred thousand dollars, a brand-new identity, and her unyielding ambition, she disappears into the horizon, completely unapologetic and ready to conquer her next target.
