My Teacher is a Zombie

Stanley and his best friend, Bert, are eighth graders just trying to get through middle school and move on to high school. Just like other kids they have things to deal with day-to-day; lunch, bullies, grades, parents. What they did not expect to have to deal with is an old teacher that has become a zombie! Knowing that that their parents won't understand their teacher's evolution into the undead, they take matters into their own hands. With the help of some of their classmates, Penny, William, and Zita, and also accompanied with Rex, the biggest kid in the eighth grade, they head to school to deal with their teacher. To get out of the eighth grade, passing class won't be enough.
