Miss Grace is a new teacher replacing Miss Melisa who left Permata Putri School because she cannot cope with the behavior of the students. One of Miss Grace’s first actions is moving one of the student named Dinda to “the empty chair,” a chair that was never occupied before. Miss Janet had frequently warned everyone, including Miss Grace, that no one should mess with “the empty chair.” Almost right away, strange things began to happen. Dinda gets possessed. Miss Grace is also terrorized.
