Piano Concerto No. 2 written by Russian composer Dmitri Shostakovich, is the fourth segment in Fantasia 2000 . The animated segment is based on Hans Christian Andersen's fairy tale The Steadfast Tin Soldier .
A boy receives a set of toy soldiers and arrays them on a table top. One Tin Soldier stands on a single leg, having been the last one cast from an old tin spoon.
Nearby, he notices a Ballerina and for a moment, thinks she has one leg like him. However, she lets down her second leg from under her dress, disappointing him. Despite this letdown, she notices him and they quickly fall in love. However a jealous Jack-in-the-Box eyes the beautiful dancer and wants her all for himself. After trapping the ballerina in a water goblet, the Jack-In-The-Box casts the Tin Soldier out of the house using a barrage of blocks and a wooden boat. Using the boat to stay above the water, the soldier rolls into the sewers, and, after evading an army of rats, is gobbled by a trout. Fishermen reel up the trout soon after and find the soldier in its mouth. They return it to its owner, and the Tin Soldier soon re-engages the evil Jack-in-the-Box.
The Jack-in-the-Box utilizes a sword and attacks the soldier. However, the Tin Soldier dodges the attack and outmaneuvers him into a fireplace. The antagonist burns to ashes after falling into the pit and the Tin Soldier and the Ballerina happily reunite.
