While on her evening run, serial killer expert Dr. Charlotte Stone comes across a bloodied and hysterical woman who raves to Charlie that she was forced to kill two others. Though unsure if this gut-wrenching story is true, Charlie gets her to a hospital. But then she remembers an almost identical story told to her by a prisoner incarcerated at Wallens Ridge. Drawing on her despised ability to communicate with the newly dead, Charlie discovers a vicious serial killer is on the loose. Dubbed the Ringmaster, this killer forces his kidnap victims to play sadistic, murderous games. VICAP Special Agents Tony Bartoli, Buzz Crane and Lena Kaminsky are investigating for the feds, with Charlie brought in to advise them. While Tony makes it clear that he would like to be more than friends with Charlie, she continues her love affair from Hell with dead man and convicted killer Michael Garland. In fact, it heats up as they track down this stone cold killer. At first, no one realizes that the Ringmaster is determined to involve Charlie in his evil games, but then it becomes terrifyingly clear that he's much closer than anyone realizes.
