When psychologist Dr. Susan Chandler uses her call-in radio show to explore the issue of lonesome women who disappear and are later found to have been victims of seductive killers, she has no way of knowing she is exposing herself - and those closest to her - to the very horror she is warning others against. After a listener calls in offering information about the mysterious disappearance from a luxury ocean liner of wealthy investment advisor Regina Clausen, the caller meets with a terrible accident. Or so say the police. As Susan begins to investigate, she quickly finds herself in a race against time - and an assassin who targets not only vulnerable women, but anyone who might offer clues to his identity. Inching closer to the truth, Susan makes shocking dual discoveries: that the killer may be an important figure in her own life, and that she herself is marked for murder.
