Girl Dorothy lived with Uncle Henry and Aunt Em in the Kansas steppe. Uncle Henry was a farmer, and Aunt Em ran the household. Hurricanes often raged in these places, and the family escaped from them in the cellar. Once Dorothy hesitated, did not have time to go down to the cellar, and a hurricane picked up the house and carried it along with Dorothy and the dog Totoshka, no one knew where. The house landed in the magical land of Oz, in the part where the Chewers lived, and so successfully that it crushed the evil sorceress who ruled in these parts. The munchkins were very grateful to the girl, but could not help her return to her native Kansas. On the advice of the good sorceress of the North, Dorothy goes to the Emerald City to the great sage and wizard Oz, who, in her opinion, will certainly help to be with Uncle Henry and Aunt Em again. Having put on the silver shoes of the dead evil sorceress, Dorothy sets off for the Emerald City along a road paved with yellow brick. Soon she meets Scarecrow, who scared a raven on a cornfield, and they go to the Emerald City together, since Scarecrow wants to ask the great Oz for a little brain.
Then they find in the forest a rusted Lumberjack who is unable to move. Greasing it with butter from the grease fitting that was left in the hut of this strange creature, Dorothy brings him back to life. The Lumberjack asks him to take with him to the Emerald City: he wants to ask the great Oz for a heart, because, as it seems to him, he cannot truly love without a heart.
Soon, Leo joins the squad, who assures new friends that he is a terrible coward and that he needs to ask the great Oz for a little courage. After going through many trials, friends arrive in the Emerald City, but the great Oz, presenting himself in a new guise to each of them, sets the condition: he will fulfill their requests if they kill the last evil sorceress in the country of Oz, who lives in the West, waving timid and intimidated by the Miguns.
Friends hit the road again. The evil sorceress, noticing their approach, is trying in many different ways to destroy the uninvited guests, but the Scarecrow, the Iron Lumberjack and the Cowardly Lion show a lot of flair, courage and desire to protect Dorothy, and only when the sorceress calls the Flying Monkeys does she manage to gain the upper hand. Dorothy and the Cowardly Lion are captured. The lumberjack is thrown onto sharp stones, straw is poured from the Scarecrow. But the evil sorceress of the West did not rejoice for long. Driven to despair by her bullying, Dorothy doused her with water from a bucket, and, to her surprise, the old woman began to melt, and soon only a dirty puddle remained of her.
Friends return to the Emerald City, demand the promised. Great Oz lingers, and it turns out that he is not a magician and a sage, but the most ordinary deceiver. At one time he was a circus balloonist in America, but, like Dorothy, he was brought into the country of Oz by a hurricane, where he managed to deceive the gullible locals and convince them that he was a powerful wizard. However, he fulfills the requests of Dorothy's friends: he stuffs the Scarecrow's head with sawdust, which makes him feel a rush of wisdom, inserts a scarlet silk heart into the chest of the Lumberjack and gives the Cowardly Lion a drink of some potion from the bottle, assuring that now the Tsar of animals will feel brave.
It’s more difficult to fulfill Dorothy’s request. After much thought, Oz decides to make a big balloon and fly back to America with the girl. However, at the last moment, Dorothy rushes to catch Totoshka who escaped, and Oz flies away alone. Friends go for advice to the good sorceress Glinda, the ruling southern country of Quodling. On the way, they have to withstand the battle with the Warring Trees, go through a porcelain country and get acquainted with the very unfriendly Shooting Heads, and the Cowardly Lion cracked down on a giant spider that kept forest residents in fear.
Glinda explains that the silver shoes taken by Dorothy from an evil sorceress in the land of the Munchkins can take her anywhere, including to Kansas. Dorothy says goodbye to friends. Scarecrow becomes the ruler of the Emerald City. The Lumberjack is the master of the Miguns, and the Cowardly Lion, as it should be, is the king of the forest inhabitants. Soon, Dorothy and Totoshka find themselves in their native Kansas, but without silver shoes: they were lost along the way.
