Miraculous holders from another world appear in Paris. They come from a parallel universe where everything is reversed: the holders of the Ladybug and Black Cat Miraculouses, Shadybug and Claw Noir, are villains, and the holder of the Butterfly Miraculous, Hesperia, is a superhero. Ladybug and Cat Noir will have to help Hesperia face the attacks of her evil doppelgangers and prevent them from taking over Butterfly’s Miraculous. Can our heroes also help Hesperia make Shadybug and Claw Noir better people?
