Based on true events, the tale stars Eric Bana as real life exorcist and New York police officer Ralph Sarchie, struggling with personal issues, who begins investigating a series of disturbing and inexplicable crimes. He joins forces with an unconventional priest (Édgar Ramirez), schooled in the rituals of exorcism, to combat the frightening and demonic possessions that are terrorising their city. It's all based on the book that details Sarchie's bone-chilling real life cases.
As this trailer makes pretty clear, the horror element hits closer to home for Sarchie, especially when it affects his wife (Olivia Munn) and daughter (Lulu Wilson).
With Sean Harris (Prometheus), Joel McHale (Ted), Dorian Missick (The Bounty Hunter) and Antoinette LaVecchia (Delirious) also in the cast, Deliver Us From Evil creeps into out cinemas on 22 August.
