The fairytale story revolves around a young prince who - along with his entourage - is turned into a nutcracker through his own ungrateful and selfish behaviour, and awaits a kindly soul who'll release him from the spell. The mouse-king seeks the magic that made this happen so that he can become all-powerful. The prince (now a nutcracker) finds hope in the form of a girl who risks everything to help him become real again, while the mouse-king and his armies do everything they can to steal the magic for themselves.
Marie's favorite Christmas toy, the Nutcracker, comes alive and, after defeating the evil Mouse King in battle, whisks her away to a magical kingdom populated by toys.
