Based on the acclaimed novel by Phil Rickman, this truly spine-tingling (The Daily Telegraph, UK) drama stars Anna Maxwell Martin (The Bletchley Circle, Death Comes to Pemberley) as country vicar Merrily Watkins who is in training to be an exorcist, or deliverance minister, for the Church of England. When Merrily is called in to consult on a grisly murder investigation, the inexperienced exorcist finds herself battling supernatural terrors that threaten to overwhelm her. CC Available.
