Marie falls asleep in her bedroom. But even in her sleep, she keeps worrying about the broken Nutcracker. The clock beats midnight. By the wave of Drosselmeyer’s hand, everything changes: room walls move apart, the Christmas tree begins to grow, and all toys come to life. Tin soldiers under the command of the Nutcracker march around the room. Suddenly, mice come out of the underground, led by the Mice King. The dolls are terrified and confused. Only the courage of the Nutcracker saves them. A seemingly unequal battle is tied up, and the Nutcracker is left alone with the King of Mice and his retinue. Marie, seeing the danger threatening her toy, takes off her slipper and throws it at the King of Mice. Mice scatter scared. And then a miracle happens …. There is no more funny ugly doll – a handsome prince stands in front of Marie. He thanks her for his salvation and invites her to follow him. The waltz of the snowflakes accompanies our heroes in their dance.
