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.
Psychotic Angela is itching to do what she does best: slaughter dozens of teenage campers. As luck would have it, the previous site of her murders has been renamed and converted into an experimental summer camp meant to bring together privileged and lower-class teens. On the day the youths are boarding the buses to camp, Angela runs over a potential camper with a garbage truck and assumes her identity. Once she has infiltrated the camp, the real terror begins.
