In this movie adaptation of L. Frank Baum's classic books, Dorothy, who has returned home to Kansas after her adventure in Oz, has trouble readjusting to life after the tornado and her infamous journey. Naturally, no one believes Dorothy's tale, and when Dorothy suffers insomnia, a desperate Aunt Em enlists the aid of a doctor at a medical clinic who, unbeknownst to Dorothy and Aunt Em, performs harmful experiments (nothing graphic -- it's just suggested) on children. In the midst of a rainstorm, Dorothy escapes the clinic to the nearby river, and floats to freedom in a chicken coop, only to awaken in the morning to find herself once again in the mystical and magical world of Oz with a chicken named Billina (who can talk when they appeared in The Land of Oz). Once there, however, Dorothy is soon horrified to realize that the land is in peril, and is now controlled by the evil Nome King. The evil witch Mombie wants Dorothy's head to add to her collection of heads. Now it's up to Dorothy to once again save the land she has come to love with the help of Billina and their new friends who are the clockwork Tik-Tok (AKA The Royal Army of Oz), Jack Pumpkinhead, and a Grump-Thing to defeat the evil Nome King and Mombie and save the Scarecrow, the Tin Man, the Cowardly Lion, and all of Oz along and restoring the Land of Oz and it's ruler to her rightful throne.
