As a member of the FBIs Psychological Profile Unit, Selby Younger and her partner, Cole Grayson, help capture William Morrano, a sadistic and intelligent serial killer. Before getting caught, Morrano attacks Selby, nearly killing her and leaving her with serious psychological wounds. Two years later, Selby is working a desk job when Morrano escapes. No hes back with a vengeance and he informs the FBI that he really wants Selby to be on the case. She's reluctant, at first, but when Morrano starts targeting people close to her, Sleby agrees to face her personal traumas again.
