Little girl Dorothy Gale (Judy Garland) lives with her aunt and uncle on a farm in central Kansas. One day, when a tornado hit, Dorothy failed to hide in time to find her beloved puppy. The powerful tornado swept the cabin where Dorothy was hiding into the air. I don't know how long it took for the cabin to fall to the ground and crushed an evil witch to death. Under the guidance of the kind-hearted northern witch, Dorothy and the puppy set off to the Emerald City where the wizard Oz (Frank Morgan) lives, begging him to help him go home. On the way, Dorothy meets the brainless scarecrow (Ray Bolger), the heartless tin man (Jack Haley) and the timid lion (Bert Lahr). In order to realize their wishes, they move forward with Dorothy. There are many difficulties and dangers along the way, and there are even more evil Western witches who obstruct them everywhere. Can their wishes finally come true? This film is based on the American fairy tale of the same name.
