A very hard-working single mother (Carice van Houten) and her son Jack (Emjay Anthony) live a life of dependence. However, the horrible changes that happened to Jack made his already difficult life even more difficult. The clergy had no way to deal with Jack, who seemed to be possessed by evil spirits. In desperation, they decided to ask the famous scientist Dr. Seth (Aaron Eckhart) to come out. Dr. Seth lost his beloved in a car accident and lost his ability to move. He could only live in a wheelchair for the rest of his life, which made him feel very painful and desperate. Seth, who never believed in ghosts, chose to use scientific methods to explore the secrets hidden in Jack. Through some scientific means, Seth sneaked into Jack's subconscious.
