After Dorothy returned to Kansas City, she had been obsessed with the beautiful country of Oz, but unfortunately, on the way back, the Ruby Slippers who could help her travel back and forth between two dimensions at will disappeared. For Dorothy's story, the aunt and uncle not only did not believe it, but also expressed concern, and took her niece to a mental hospital for treatment. There, Dorothy shudders at the misbehaving head nurse. Fortunately, with the help of a strange girl, she managed to escape from the mental hospital and down the river with a wooden board. When she woke up again, she found that she and the old hen Bilina had come to the land of Oz full of lunch boxes.
Dorothy, who doesn't know how to get back, has to seek help from her former friend, the scarecrow, the king of the Emerald City. Dorothy and the hen Bilina carefully crossed the desert of death, but unexpectedly fell under the surveillance of the stone king Norm. When they came to the Emerald City, they were surprised to find that the once beautiful and happy Emerald City had become desolate, and everyone had been turned into stone. Before they could find out the truth of the matter, the wheelers under the witch Mumby launched an attack on them. Fortunately, with the help of the robot Tick, Dorothy was able to turn the corner. In order to find the scarecrow in danger, Dorothy, Dida and others had to venture to the palace of the witch Mumby, but did not want to be locked up by her.
At the Witch's Castle, Dorothy accidentally encounters Jack the Pumpkin and a decorative elk, and brings them to life with life powder stolen from the Witch. As a result, several people worked together to escape the control of Mumby and went to the end of the world. After several days and nights of flying, the elk finally stopped on a desolate island, but unexpectedly, it fell into the ecstasy of King Nome. In order to save the Scarecrow, they came together to the beautiful but mysterious underground palace of Nome. As a result, the scarecrow was turned into a decoration for King Nome. King Nome gave Dorothy and her friends three chances to guess the scarecrow from the decoration. Turn them into decorations too. Seeing that the entire army was about to be wiped out, Dorothy got the right one and rescued the scarecrow and found a pattern to rescue everyone. King Norm was furious and wanted to throw Dorothy and the others into his mouth, before he wanted to eat Jack. Belina, who was hiding in the pumpkin, just laid an egg and fell into the mouth of King Nome. The egg was poison to the people in the stone kingdom, and they defeated King Nome in this way. In the end, they not only recaptured the Emerald City, but also accidentally discovered Princess Ozma who was locked in the mirror by Mumby, the mysterious girl who rescued Dorothy in the mental hospital. Dorothy rescued Princess Ozma, became good friends with her, and gained the magic power to return to Oz at any time.
