During the night, after everyone else has gone to bed, Clara returns to the parlor to check on her beloved nutcracker. As she reaches the little bed, the clock strikes midnight and she looks up to see Drosselmeyer perched atop it. Suddenly, mice begin to fill the room and the Christmas tree begins to grow to dizzying heights. The nutcracker also grows to life size. Clara finds herself in the midst of a battle between an army of gingerbread soldiers and the mice, led by their king. The mice begin to eat the gingerbread soldiers.
