The story is about Amber, a mean popular girl who gets electrocuted and dies and is not allowed to enter into heaven unless she helps the least popular girl in school become Prom Queen within a week, but things do not go as planned.

With Prom only hours away, the usual suspects of Cosa High (Cheerleaders, geeks, bad boys and the happy-go-lucky student council alike) are preoccupied with the annual rituals of teendom. On the night of the big dance when the dead unexpectedly rise to eat the living, polar opposite groups will be forced to unite in their final chance to save the town from the zombies.
