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.
Whilst attending the opening night of an art exhibition, Princess Luna notices her sister admiring one of the ponies there more than the paintings. She tries to find out what is so special about the millionaire patron of the arts Fancy Pants.
Sisters, Cadence and Fluttershy, are told the legend of the "Sleeping Princess" by their father, Soarin', only to find that it is indeed true and it's up to the two of them to break a curse and also find the lost Prince of the Everfree Forest.
Shining Armor and Cadence spend a night together at last, just with each other. But as the night progresses, there might be something still to derail their perfect night.
