A spilled cup of coffee on a flight from London turns into a nightmare for Flight Attendant Christine Lindsey when she awakens a killer's desires. When she begins to receive unwanted attention and gifts from wealthy businessman Luther Ross-Wilkerson, she passes him off as just another passenger with a crush. But this passenger is a murderer who will stop at nothing to have her. Luther continues to pursue Christine, at the same time unleashing a spree of killings throughout San Francisco - his victims all women who resemble not only Christine but another woman who spurned Luther years before. Police Lieutenant John Kinsella realizes there is a clever serial killer at work, but his only clue is a description of a man seen with two of the victims before their deaths. Christine grows increasingly disturbed by Luther's persistent odd behavior, but by the time her closest friend discovers that Luther is the city's serial killer and Christine is his main target, it just might be too late to save her.
