Following in the wake of The Last Exorcism (2010) which enjoyed box office success, The Devil Inside also includes two staples of horror cinema: supernatural possession and the found footage/faux documentary genre. On paper these themes have the potential to yield an interesting drama. Sadly that is not the case with The Devil Inside which excels at neither and is distinctly average at best. It lacks the gravitas and visceral power of The Exorcist and even the sensational shock value of Paranormal Activity. The plot focuses upon Isabella (Fernanda Andrade), an American woman who sets out to make a documentary about her mother who murdered three members of the clergy. She was judged insane and subsequently sent to a mental hospital in Italy. Isabella meets two priests, Father Ben Rawlings (Simon Quarterman) and Father David Keane (Evan Helmuth) who explain that her mother's condition may be due to demonic possession.
