Possessed by the Devil(2013)

Possessed by the Devil follows Eddy, a skeptical demonologist obsessed with proving Satan's existence through hard evidence. For nearly two years, his logical investigations have yielded nothing but frustration. Desperate to finally make contact with the supernatural, Eddy abandons reason and turns to increasingly dangerous occult rituals. What begins as an intellectual pursuit transforms into something far darker when his extreme methods actually work—but not in the way he expected. The film explores the thin line between faith and obsession, skepticism and belief, as Eddy discovers that some doors, once opened, cannot be closed.
