It is storied that there are two best friends since they were kids, Laine (Olivia Cooke) and Debbie (Shelley Hennig) who love to play an ancient game using and old board named Ouija when they were kids. Based on the myth, the board can call a spirit and can be such a bridge between the spirit and the player who has a certain relationship with it. Since they were still kids, the two tried to play it. The time goes by, the two were grown. When cleaning her house’s roof, Debbie find the Ouija board again.
Without Laine knows, Debbie tries to play the game alone. Then she did it. She can really communicate to a spirit who is in her house. After playing, Debbie often does weird things and loves to be alone in the house rather than hanging out with friends. In fact, her best friend, Laine is not permitted to come in her house anymore. Laine is curious and becomes worry. Finally a worst thing happens. Debbie is found hanging in her house. She is dead.
