This is one of those examples of a horror piece that is so simple, yet so effective. A teacher is grading papers and notices a student's name, Erma. From then on things get really ramped up and threat abounds. What appears to be a little girl with black hair over her eyes and the ability to float from one place to the next and go through walls. The finale is quite unique. By the way, after 43 years of teaching, there isn't anything quite like a school building after everyone has left.
