The dead will walk... on the night of the High School prom. As the students of Cosa High get ready for the most important night of their high school lives, the dead are getting ready to go on the rampage. Since most of the students are unaware of the threat, it’s up to a small group of outcasts to save the day and thwart the undead foe. The usual prom rituals of worrying about their dates, showing off dresses and travelling in limousines don’t apply for class-clown, Jimmy, and his socially awkward friends as they must face something much more sinister: hordes of the undead rampaging through their town!
