When a zombie apocalypse breaks out in Equestria, it is up to Rarity, Apple Jack, and the new pony in town (Ginger Melody) to defend the survivors in Ponyville and Canterlot from the ponies that they used to know. When somepony becomes infected, he or she is hardly a shadow of the pony they used to be. Their brains and bodies begin to rot and they turn into flesh-eating monsters who will stop at nothing to take a bite of somepony else.
