King William and his friend Queen Uberta both have a child; Uberta has a son named Derek and William has a daughter named Odette. The two want their children to marry when they grow up so they can unite their two kingdoms forever. However, a villainous sorcerer named Rothbart plans to take King William's kingdom for himself. William discovers his plans and Rothbart is banished, swearing revenge on him. Derek and Odette hate each other as children but when they reach adulthood, they finally fall in love. However, when Derek is unable to think of anything he loves Odette for besides her beauty, she rejects him in disappointment. On her way home, she and her father are ambushed by Rothbart, who transforms into a "
Great Animal", kidnapping Odette and mortally wounding William. The dying William tells Derek about the Great Animal and Odette's disappearance. The kingdom assumes that she is dead, but Derek is determined to find her. Rothbart keeps Odette captive at Swan Lake, where he puts her under a spell where Odette transforms into a
swan during the day, and temporarily back into a human at night if she stands on the lake when the moonlight touches it. Rothbart's goal is to marry Odette so he can rule the kingdom. During her captivity, she befriends a
turtle named Speed, a French
frog named Jean-Bob, and an Irish
puffin named
Lieutenant Puffin. The next day, Odette and her friends venture into Rothbart's castle to get a map. In the forest, Derek mistakes Odette for the Great Animal and tries to kill her. The ensuing chase leads him to Swan Lake, where he witnesses her reverting into her human form. Odette tells Derek that to break the spell, he must make a vow of everlasting love. He invites her to the ball, hoping to declare to the world his love. However, Rothbart transforms his hag sidekick, Bridget, into a
doppelgänger of Odette to deceive Derek into making his vow to the wrong woman, which will kill the real Odette. On the night of the ball, he imprisons Odette and Derek's friend Bromley. Odette's animal friends free her and she flies to the castle to warn Derek, but he ends up making the vow. Realizing his mistake, Derek follows Odette back to Swan Lake, where she dies in his arms. A distraught Derek angrily confronts and battles Rothbart and with the help of Bromley and Odette's animal friends, kills him. Derek then confesses his love to Odette, realizing that it is the person Odette has become that he loves about her, and she comes back to life; the spell on her is broken by his love. Derek and Odette get married and they, along with his mother, Rogers, Bromley, King William's servants, and the animals move into Rothbart's castle. == Voice cast ==
