Dorothy Gale, a young girl living on a Kansas farm with her Aunt Em and Uncle Henry, dreams of escaping her mundane life. The family?s mean neighbor, Miss Gulch, threatens to impound Dorothy?s cherished dog, Toto, so Dorothy and Toto run away. They meet up with kindly Professor Marvel, who subtly convinces Dorothy to return home. Suddenly a cyclone hits, and Dorothy and Toto, seeking shelter in the house, are transported to the Land of Oz.
In Oz, Dorothy meets Glinda, the Good Witch of the North (who has an uncanny resemblance to Aunt Em) and learns that her house has landed upon ? and fatally stricken ? the Wicked Witch of the East. The Munchkins, now freed from the Wicked Witch of the East, celebrate and hail Dorothy as their new heroine. The celebration is interrupted when the Wicked Witch of the West appears, and after being unable to reclaim her sister?s ruby slippers that are now on Dorothy's feet, the Wicked Witch threatens vengeance. Dorothy, seeking a way back home to Kansas, sets off to see the Wizard of Oz.
