When a U.S. congressman’s daughter, passing through a small town in Mississippi, dies in a mysterious triple homicide, a team of F.B.I. agents investigates. Lead agent, Vaughn Killinger (James Callis), battles personal demons as his partner, Sarah Desoto (Christiane Seidel), tries to hold him and the case together. They find a struggling and corrupt sheriff’s department, run by a chief deputy (Miles Doleac), who runs drugs for a shadowy figure, John Dawson (William Forsythe (actor)), who seems to be pulling all of the town’s strings from his antebellum mansion on the outskirts of town.
