Marinette, a dance prodigy, currently attends an academy based on its reputation of exquisite dancers and movers. With perfection in every movement she makes, the girl still can't catch the eye of her long-lasting crush, Adrien Agreste. He's the lead male's dancer and has been dancing since he could walk. After finding herself in a night club and witnessing a boy, bathed in the dark color of jet black and little sections of green, dance in such a free and rhythmic way, she begins to frequently go to the club, taking note from the boy. She clads herself in an attire of her own, going under the name "Ladybug". Marinette becomes a great hit and begins to join dance battles and acquaints herself with the blonde male who goes by "Chat Noir". Is her double life as a ballet dancer and breakdancer perfect, or will she begin to switch her feelings?

Tom(Marinette's dad) goes for mayor.
