As prom gets underway and the dead come out to play, the only hope for saving the day is the mismatched couple that can't seem to agree on anything. As the Cosa High School Senior Prom draws near, the local teens are more preoccupied with getting laid and looking good on the big night. But while local teen Jimmy (Jared Kusnitz) seems completely unfazed by all the infectious enthusiasm that's spreading through the student body, his girlfriend Lindsey (Greyson Chadwick) has thrown herself into the teenage ritual and remains determined to have the perfect romantic evening. But it's kind of difficult to enjoy an intimate dance when your classmates are trying to eat your brains, and when the tux-clad teens begin turning blue and munching on flesh, Jimmy and Lindsey are forced to put their differences aside long enough to extinguish the zombie plague before it spreads beyond campus grounds.
