Blue Heart is a young unicorn filly, but she has always wanted to fly up in the sky, graceful as a bird. When she asks her friend, Twilight Sparkle, to teach her the ways of magic, a spell she casts goes horribly wrong.
While in the human dimension, Emily lives peacefully. She is a fan of My Little Pony: Friendship is Magic, but she hides it from her friends, who think "she's too old" to watch "baby" shows. But one day, Emily wakes up to find that she has been turned into a Pegasus!
Will Blue Heart ever fly? Will Emily ever turn back into a human?
