The clock striking eight entails that arrival of Drosselmeyer, a local magician. He has also brought gifts for the children, including a nutcracker doll for which, Clara, one of the children, develops a liking. At midnight, an army of mice, lead by the Mouse King, attacks the party. The nutcracker grows to life size and launches a counter attack supported by tin soldiers and other dolls. The nutcracker is wounded and Clara helps him kill the Mouse King.
