Clara (Mackenzie Foy) wants a key - a one-of-a-kind key to a box that holds a priceless gift from her late mother. A golden thread, presented to her by godfather Drosselmeyer (Morgan Freeman), leads her to a mysterious parallel world where she encounters a soldier, a gang of mice, and the regents of three fantastical realms: Land of Snowflakes, Land of Flowers, and Land of Sweets.
But to retrieve her key, and hopefully return harmony to the unstable world, Clara must brave the ominous Fourth Realm that's home to the tyrant Mother Ginger (Helen Mirren).
Starring Kiera Knightley as the Sugar Plum Fairy, Disney's new holiday feature promises to reveal the dark side of the classic Christmas tale.
