A serial killer massacred the family of FBI agent Smokey Barrett and then disfigured her face. She shot the criminal - but neither revenge nor justice saved her from painful experiences and feelings of guilt. However, now Smokey is forced to pull herself together and call on all her professionalism to help: she has to investigate the case of a mysterious maniac calling himself the Stranger. This mysterious criminal, fixated on the sixteen-year-old beauty Sarah, has been killing everyone she cares about for many years. A classic case of a crazy killer and his muse? At first, Smokey and her team are sure of this. But gradually it becomes clear to them: a “dark passion” for Sarah - just the entrance to the labyrinth of dark fantasies of the Stranger, who has a personal account with the FBI.
