The movie "Dr. Cheon Exorcist Lab" is adapted from the webtoon of the same name. It tells the story of a fake exorcist named "Dr. Cheon" (played by Kang Dong-won), who can't hear ghosts but solves various cases with his ghostly insight. He is commissioned to deal with a strong possession case that he has never experienced before. "Dr. Cheon Exorcist Lab" is produced by the soft and strong company that produced "Veteran", "Exit" and "Mogadishu". This is also the feature film debut of Kim Sung-sik, who served as assistant director of "Decision to Part", "Parasite" and "Save Me from Evil".
