Dorothy is a young girl who lives with her Aunt Em, Uncle Henry, and dog, Toto, on a farm on the Kansas prairie. One day, she and Toto are caught up in a cyclone that deposits them and the farmhouse into Munchkin Country in the magical Land of Oz. The falling house has killed the Wicked Witch of the East, the evil ruler of the Munchkins. The Good Witch of the North arrives with three grateful Munchkins and gives Dorothy the magical silver shoes that once belonged to the Wicked Witch. The Good Witch tells Dorothy that the only way she can return home is to follow the yellow brick road to the Emerald City and ask the great and powerful Wizard of Oz to help her. As Dorothy embarks on her journey, the Good Witch of the North kisses her on the forehead, giving her magical protection from harm.
On her way down the yellow brick road, Dorothy attends a banquet held by a Munchkin named Boq. The next day, she frees a Scarecrow from the pole on which he is hanging, applies oil from a can to the rusted joints of a Tin Woodman, and meets a Cowardly Lion. The Scarecrow wants a brain, the Tin Woodman wants a heart, and the Cowardly Lion wants courage, so Dorothy encourages them to journey with her and Toto to the Emerald City to ask for help from the Wizard. After several adventures, the travelers arrive at the Emerald City and meet the Guardian of the Gates, who asks them to wear green tinted spectacles to keep their eyes from being blinded by the city's brilliance. Each one is called to see the Wizard. He appears to Dorothy as a giant head, to the Scarecrow as a ball of fire, to the Tin Woodman as a lovely lady, and to the Cowardly Lion as a terrible beast. He agrees to help them all if they kill the Wicked Witch of the West, who rules over Winkie Country. The Guardian warns them that no one has ever managed to defeat the witch.
