In the small town of Hope, Roland Recht is a detective, a deeply religious man trying to understand his place in an increasingly secular world.
And his latest case, the murder of an isolated pastor, hits him harder than usual.
Killed within the Congregation of Saul's compound, the only witness is Lizzie, the group's newest and youngest follower, and it seems clear that a former member must be responsible.
But when Recht and his girlfriend suffer a personal and terrifying threat, it sends the investigation in a new direction, one that no one - not even his superiors or the FBI - wants him to pursue.
Never the Sinner sees a good man forced to choose between continuing his career as a cop, and seeing true justice done.
