Dorothy Gale inadvertently crushes an evil witch with her house when it (and her) are transported by a tornado to a faraway land called "Oz".
The girl from Kansas is told that she must visit the Wizard who lives in the Emerald City, for he is the only one with the power to return her home!
Following the Yellow Brick Road (which goes directly to the green metropolis), she encounters three strange (but friendly) beings who agree to accompany her.
Overcoming dangerous obstacles, the group reaches the city...and an audience with the awesome Wizard!
Proclaiming he can return Dorothy home, Oz (as the Wizard calls himself) demands that she slay the Wicked Witch of the West or he won't aid the girl from Kansas.
