Sofia and Prince Hugo are really looking forward to seeing the ballet "Swan Lake"...until the ballet is cancelled at the last minute because half the cast is sick. The ballet will be postponed, but nobody knows when. As Sofia and Hugo have another date to make up for the cancelled one, Sofia teaches Hugo how to dance ballet. When some princesses see this, they decide to help Sofia and Hugo perform "Swan Lake" for their friends and families with Hugo as the prince (of course!) and Sofia as Odette. This ballet just might be fun...except with Hildegard trying to take over the spotlight.
