In 1985, a famous exorcist managed to confine a terrifying demon within a ouija board. Believing the board to be a mere toy, his son disregarded the rules and inadvertently released the demon. To protect his son, the exorcist sent him away until the demon could be vanquished. Three decades later, after the exorcist’s passing, his grandson discovers the board and repeats his father’s error. Now, the malevolent force has returned, seeking vengeance on those who once imprisoned it.
