Prince Siegfried is told by his mother the Queen to find a bride at the royal party the following evening. He does not want to and goes hunting on the lake shore, where he meets girl-swans among whom is Odette. They fall in love. Odette tells him that she was turned into swan by the evil magician Rothbart and that the only way the spell can be broken is if a man, pure in heart, pledges his love to her. The following day, Rothbart and his daughter Odile appear at the party, and Odile, who looks just like Odette, seduces Prince Siegfried. In front of Prince Siegfried, dancers from around the world perform national dances, but they are also under the spell of Rothbart.
Can Prince's true love prevail!?
