As per tradition, after Flurry Heart's birth, Twilight's family takes a trip to their ancestral castle in order to introduce her to her great-grandparents. The rest of the girls come along too, eager to see the place. But when they get there; they learn strange rumors concerning the place and their friend's family. The large and foreboding place itself doesn't help either. Throw in a creepy caretaker, dark family secrets and hidden passageways, and soon they find themselves wondering if they truly know their friend as well as they thought they did.
