Act I
Prince Siegfried arrives at his 21st birthday celebration on the palace courtyards to find all of the royal families and townspeople dancing and celebrating, while the young girls are anxiously seeking his attention. During the exquisite celebration, his mother gives him crossbow and informs him that because he is of age now, his marriage will be quickly arranged. Hit with the sudden realization of his future responsibilities, he takes his crossbow and makes haste to the woods with his hunting buddies.

Act 2
Getting ahead of the group, Prince Siegfried finds himself a peaceful spot by an enchanted lake where swans gently float across its surface. While Siegfried watches, he spots the most beautiful swan with a crown on its head. His buddies soon catch up, but he orders them to leave so he can be by himself. As dusk falls, the swan with the crown turns into the most beautiful young woman he has ever seen. Her name is Odette, the Swan Queen. She informs the young prince that an evil sorcerer, Von Rothbart, who so happens to be disguised as Prince Siegfried’s mentor, has turned her and the other girls into swans and that the lake was formed by the tears of their parents' weeping. She tells him that the only way the spell could be broken is if a man, pure in heart, pledges his love to her. The Prince, about to confess his love for her, is quickly interrupted by the evil sorcerer. He takes Odette from Prince Siegfried’s embrace and commands all of the swan maidens to dance upon the lake and its shore so that the prince cannot chase them. Prince Siegfried is left all alone on the shore of Swan Lake.
