Plot

Mae Zalinski is a 20-something girl who reluctantly takes a job as a substitute teacher at her old rival high school. Mae has her first day as things go from bad to worse as she starts to uncover the strange, possibly evil underbelly of this seemingly perfect high school. From the odd, overly-friendly vice-principal to the Children-of-the-Corn-esque students, Mae is soon in way over her head.
