A toymaker (Semon) reads L. Frank Baum's book to his granddaughter.
The Land of Oz is ruled by Prime Minister Kruel (Josef Swickard), aided by Ambassador Wikked (Otto Lederer), Lady Vishuss (Virginia Pearson), and the Wizard (Charles Murray), a "medicine-show hokum hustler". When the discontented people, led by Prince Kynd (Bryant Washburn), demand the return of the princess, who disappeared while a baby many years before, so she can be crowned their rightful ruler, Kruel has the Wizard distract them with a parlor trick: making a female impersonator (Frederick Ko Vert) appear out of a seemingly empty basket. Kruel sends Wikked on a mission.
Dorothy and the Witches of Oz, and its miniseries predecessor, follows the exploits of the grown Dorothy Gale, now a successful children's book author, as she moves from Kansas to present day New York City. Dorothy quickly learns that her popular books are based on repressed childhood memories, and that the wonders of Oz are very, very real. When the Wicked Witch of the West shows up in Times Square, Dorothy must find the inner courage to stop her.
