Margarita Kauzlaskas (a/k/a Margot), a beautiful immigrant girl from Lithuania, is determined to have it all, no matter who she has to use to get it. The result is a long list of enemies, including a jealous husband, a revengeful ex-wife, an obsessed girlfriend, and a star-crossed lover. After convincing her four best friends into taking a reunion cruise to Bermuda, on the night of the ship's return to New York, a body is spotted going overboard. The next morning, Margot is nowhere to be found.
Enter FBI Agent Richard Heller, whose early abandonment issues cause him to become obsessed with finding out what happened to the infamous femme fatale. As the investigation unfolds, an aura of foul play descends upon her friends as well as her enemies. With insufficient evidence to convict, the case grows cold--until he receives an anonymous envelope in the mail. Is it someone's idea of a joke, or can it help him solve the mystery once and for all?
