The complete opposite of the Warren’s from the movie The Conjuring, self-proclaimed occult expert Dr Steven Caramore ekes out a living debunking claims of possession and the supernatural with his Haitian confidant, Ola. However, when a friend and colleague, Ben Dollarhyde, is accused of murder, claiming he was possessed by something demonic, Caramore is forced to question his own beliefs. He litters his deceased father’s apartment with items that are said to be possessed or cursed, then outfits the place with surveillance equipment. He then rents the apartment to an unsuspecting family on a short city break. Caramore waits for something horrific to take effect. Nothing does, until… In a last-ditch attempt to conjure dark forces, he places the black Madonna that Dollarhyde claimed possessed him into the apartment. This sets off a chain of devastating supernatural events that forces the family, and Caramore, in a terrifying battle for survival.
