The Possession of Damien Blair (2018)

Father Martin has been a new priest of a small Christian church for a little over 3 years. During his short time with the church, he has never encountered any kind of demonic possession or had to perform an exorcism, despite having demons of his own. One day, after one of his sermons, a distressed family approaches him and asks for his help. They claim their son, Damien Blair, is possessed by demons and they want Father Martin to come investigate and perform an exorcism. Hoping to face a demon head on for the first time, Father Martin agrees to investigate. And he brings along a college kid named Stu who wants to document everything for a film project. Very quickly, Father Martin and Stu realize there is definitely something wrong with Damien Blair, regardless of whether he's actually possessed or not.
