The Bolshoi Ballet dances one of the world's most beloved ballets under the direction of master choreographer Yuri Grigorvich. Prince Siegfried (Alexander Bogatyrev) falls in love with the beautiful Odette (Natalia Bessmertnova), who is under a curse that turns her into a swan by day. Only by swearing his love can Siegfried break the spell, but when he mistakes the nearly identical Odile for his beloved, his hopes may be shattered.
