A wicked witch breaks free of the confines of the mirror after she kills the Keeper of the Fairy Tales and sets her sights on destroying Piper, Phoebe, and Paige. As a result, Piper and Grams fall victims to Wolf from Little Red Riding Hood, Phoebe to the glass slippers found in Cinderella, and Paige to the poison apple from Snow White. It takes Cole and Leo working together to find a way to vanquish the wicked witch, break the evil spell over the fairy tales, save the sisters, and set the fairy tales back to how they were originally written.

Kevin is a young witch who can bring his drawings to life. When a demon learns of his powers, he turns to Kevin, looking to turn into an evil Supervillain in order to kill a retiring Elder before he names a replacement. However, before the demon gets his hands on the young witch, he works his magic on the Charmed Ones and turns them into Superheroes. With all the superpowers raining down upon San Francisco, Piper, Phoebe, and Paige have their work cut out for them after being tasked to protect the retiring Elder.
