A deadly game of cat and mouse is playing out in Forney County...
Detective Cass Elliot is still on suspension after killing a fellow officer and Sheriff Hoffner refuses to sign her release papers. But when four people are murdered in one night, one with the exceptional brutality of a lynching, the Medical Examiner side-steps Hoffner to hire Cass and loan her to Forney County's overstretched police department. As Cass and her partner investigate, they realize that three of the murders were committed by the same person but find no connection between the victims. Their frustration intensifies when another victim survives and disappears instead of coming to the police. Sheriff Hoffner is frantic about anonymous letters claiming one of his star officers is dirty, and Cass suspects a link to the current crimes. The pieces fall together when she uncovers the true identity of the man who was lynched, revealing connections between the victims, the killer, and an unpunished crime committed nearly fifty years ago.
