All Clara wants is a keya one-of-a-kind key that will unlock a box that holds a priceless gift from her late mother. A golden thread, presented to her at godfather Drosselmeyer's annual holiday party, leads her to the coveted key - which promptly disappears into a strange and mysterious parallel world. It's there that Clara encounters a soldier named Phillip, a gang of mice and the regent who preside over the three Realms: Land of Snowflakes, Land of Flowers and Land of Sweets. Clara and Phillip must brave the ominous Fourth Realm, home to the tyrant Mother Ginger, to retrieve Clara's key and hopefully return harmony to the unstable world.Bonus Features:On Pointe: A Conversation With Misty CopelandUnwrapping The Nutcracker and the Four RealmsDeleted Scene:The Stahlbaums ArriveFollow Your RibbonClara Asks About Her MotherLeft, Left, Left, Left, LeftOut With The OldMusic Video - Fall On Me Performed by Andrea Bocelli Featuring Matteo BocelliMusic Video - The Nutcracker Suite Perfo
