Well, here is "more about Dorothy," and about our old friends the Scarecrow and the Tin Woodman, and about the Cowardly Lion, and Ozma, and all the rest of them and here, likewise, is a good deal about some new folks that are queer and unusual. And I wish I could, for I enjoy writing these stories just as much as the children say they enjoy reading them. And some of them suggest plots to me, saying: "Please have Dorothy go to the Land of Oz again" or, "Why don't you make Ozma and Dorothy meet, and have a good time together?" Indeed, could I do all that my little friends ask, I would be obliged to write dozens of books to satisfy their demands. Their sweet little letters plead to know "more about Dorothy" and they ask: "What became of the Cowardly Lion?" and "What did Ozma do afterward?"-meaning, of course, after she became the Ruler of Oz. Afterward, Dorothy sees her with Billina in her bedroom mirror, indicating that Oz was not a dream (as both movies initially implied).My friends the children are responsible for this new "Oz Book," as they were for the last one, which was called The Land of Oz. She then uses the Ruby Slippers to send Dorothy back home to Kansas, saying she would look in on her from time to time and take her back to Oz if she wishes to return. She is also revealed to be the creator of Jack Pumpkinhead, who calls her his mother.

After the Nome King is destroyed and Oz is restored to its original state, Dorothy frees Ozma from the mirror, and she reclaims her position as the rightful ruler of Oz. When Dorothy escapes, Mombi taunts Ozma in the mirror stating she is the only one who knows where she is and no one will help her escape. She later reappears to show Dorothy the way out of Mombi's mirror room when Dorothy takes the Powder of Life from Mombi's cabinet containing her real head and escapes from her castle. Ozma vanishes, and seemingly drowns presumably, she returns to her position in Oz, which was inside the mirror. Worley's machines and locked in the cellar, she rescues Dorothy from the hospital, but Nurse Wilson discovers and chases after them, resulting in them both falling into the river. After discovering that some of the patients have been damaged by Dr. She appears to her as one of the patients to comfort her and gives her a jack o' lantern (a reference to Jack Pumpkinhead) as Halloween is coming up and disappears. Somehow, she is able to appear outside Oz and talk to Dorothy at the hospital as a fellow patient. When the Nome King took over Oz and promised Mombi the heads of 30 women (to switch heads with) if she kept her a secret, she imprisoned her within the mirror. The film, which was based loosely on the books Ozma of Oz and The Marvelous Land of Oz, reveals that Ozma's father was the king of Oz before the Wizard came, and Mombi made Ozma her slave.
