The tale begins when Barbie, playing the role of Clara, receives a beautiful wooden Nutcracker as a gift from her favorite aunt. That night, while Clara sleeps, the Nutcracker springs to life to ward off the evil Mouse King who has invaded Clara's parlor. She awakes and aids the Nutcracker, but the Mouse King shrinks her by casting an evil spell. Clara and the Nutcracker set off on a spectacular adventure to find the Sugarplum Princess, the only one who can break the Mouse King's evil enhancement. Barbie in the Nutcracker shows that, if you are kind, clever and brave, anything is possible.
