Fluttershy had had many dreams about flying to the Sweet Apple Acres orchard by night, conversing with the bats and enjoying apples. But when one of her dreams takes a different turn, she and Big MacIntosh find their waking worlds turned upside-down.
While in Trotsylvania, a mare by the name of "Fluttershy" meets a gentlecolt named "Dr. Van Helstallion" and must be protected from a vampiric demon who is, not only, persuing her, but killing other young mares in the village.
