Marinette is entrusted with designing the cover of a new album of her favorite singer, rock-star Jagged Stone!

Pressured by the star’s bossy manager, Marinette second guesses her instincts and Jagged Stone rejects her design. Marinette decides to do it again – this time her way.

But in the meantime Jagged Stone – humiliated and exhausted by his rivalry with an arrogant young singer named Mr. XY – gets akumatized by Hawk Moth.

Now Guitar Villain, the hardest rock villain of all time, he rides his croc-dragon across Paris and uses his electric guitar to make the whole city dance. His goal: to take revenge on Mr. XY by turning every single Parisian into his biggest fan.

If they want to stop him, Ladybug and Cat Noir will have to sharpen their wits!
