Accept the existence of the devil

Some sort of demonic entity enters the bodies of human beings and make them do horrendous things. The fucker must be summoned through exorcism and thrown to hell. Not entirely sure, but don't think The Conjuring: The Devil Made Me Do It differs of its predecessors, The Conjuring franchise, or all the other similar movies since William Friedkin's The Exorcist (1973). A few jump scares, but a mess of a story of the same lie that the movie is based on a true story.
