Pinkie gets accepted to Hogwarts! Although her purple unicorn friend doesn't believe her at first, once she realizes it's true, she tries to find a way to sneak in to Hogwarts. But as the school year progresses, a terrible accident unleashes an evil that not only threatens to destroy the world of the Humans, but all the other worlds as well, Equestria included.

Back in Equestria, Lyra hears the words "human" and "real" come out of Twilight's mouth, and goes on quest to learn more and, finally, prove to Equestria that she isn't just an idiot who preaches about humans.
