In this forlorn place, no-nonsense, down-to-earth sheriff, Sadie Mills, does her best to bring order and justice to a community struggling with crime, drug overdoses, and hopelessness. Aiding her is Coroner Raymond Russo, who fled New Jersey for a simpler life in rural America in a last-ditch effort to escape a family crime syndicate. When the body of a young man is recovered from the Puissant River, evidence leads Sheriff Mills to a cold case murder and a rundown cabin in the woods. The hill country is a dangerous place, and Sadie doesn't know if she can trust John Dover, the mysterious loner and member of the notorious Dover clan who offers to help her uncover the truth. Events take a tragic turn when a teenaged boy from the nearby Amish settlement goes missing and Sadie suspects the cases are connected. And just when Sadie doesn't think things can get any worse, Russo's family shows up with revenge on their minds. As things heat up in Possum Gap, a horrific tale from the past emerges that threatens not only Sadie's life, but everyone she holds dear. Will the hill people unite against an outside threat to save their sheriff, or leave her and the authority she represents to fate? It's a race against time to save the lost Amish boy and battle an unthinkable evil.
