The Substitute (Ghost House)

Sixth grade has a new substitute teacher, and she is not the substitute they are used to. Apparently she can read the children's minds, and when she is alone with the pupils in class, she is downright malicious. The children immediately make a complaint about her, but she succeeds in convincing the parents that she is fantastic - though the class claims that she is an evil "alien." The substitute achieves this through her irresistible charm, and soon the parents turn their suspicions towards the children and their exaggerated imagination.
