When a tornado rips through Kansas, Dorothy and her dog, Toto, are whisked away in their house to the magical land of Oz. They follow the Yellow Brick Road toward the Emerald City to meet the Wizard, and en route they meet a Scarecrow  that needs a brain, a Tin Man  missing a heart, and a Cowardly Lion who wants courage. The wizard asks the group to bring him the broom of the Wicked Witch of the West to earn his help.
