When little Hanna takes the night train to Vienna, she dreams herself right into a toy store. There is a bustling atmosphere, and the customers can hardly believe their eyes: dolls from various countries perform dances from their homelands, how wonderful! But the most wonderful of all is the most beautiful doll, the doll fairy. As the shop owner closes his store and night falls, the toy store comes to life. Led by the doll fairy, the entire group of dolls begins a magical nighttime dance party. And Hanna can't stop marveling.
