It's a week after Nightmare Night, and the dead have risen. Zombies, ghosts and skeletons walk Ponyville's streets. It would be pretty terrifying, except for the fact that they're so nice. Also, they don't seem to realize they're dead.

But not everypony is happy with their new undead neighbors. Rainbow Dash is a little freaked out, Twilight Sparkle is on trial for murdering a skeleton, and Rarity conspires against her ghostly business partner. Will our heroes be able to keep up in a world where busy ponies don't have time to let death slow them down?
