The film is based on “real events” and follows a falling out of faith seminary student who is recruited to become a recruit of the new league of exorcists the Vatican is recruiting. There has been a recent surge in possessions as of late around the world and the Vatican is wishing to place exercisers for easy access around the world. The recruited student is Michael Kovak who is forced into priest hood by his father and when nearing graduation feels like he can’t go through with it. The Vatican’s Exorcism Head Master takes a special interest in Michael and pairs him up with Father Lucas who attempts to show Michael the way. Michael’s skepticism is tested by Lucas as he takes him through his current patient’s troubles but is really tested when things get personal.
