Prince Siegfried is celebrating his birthday with his tutor, friends, and peasants. The revelries are interrupted by his mother, the Queen, who is concerned about his carefree lifestyle. She tells him that he must choose a bride at the royal ball the following evening. He is upset that he cannot marry for love. His friend, Benno, tries to lift his troubled mood. As evening falls, Benno sees a flock of swans flying overhead and suggests they go on a hunt. Siegfried and his friends take their crossbows and set off in pursuit of the swans.

After following the flock, under the moon light he sees something magical. Swans turning to humans at the lake under the moonlight in middle of it all a graceful and ethereal ruler of the swans.
