Haunted by the death of her husband, reverend Jack Brooks (Samantha Morton) relocates to a new parish in the hope of a fresh start, free from painful memories of tragedy at her previous church. She arrives in the village of Chapel Croft, famous for its dark and turbulent history, with her headstrong 15-year-old daughter Flo (Ruby Stokes). In unfamiliar surroundings, single parent Jack unearths painful secrets among the flock and realises her new home is just as threatening and overwhelming as the life she left behind
