As children, Prince Derek and Princess Odette are forced to spend their summers together by their widowed parents, who hope that the two will eventually fall in love and marry, so their two kingdoms will be united. As children and adolescents, Derek and Odette can't stand each other, but as young adults they begin to see each other in a different light and fall in love with each other. But one night things take a bad turn when Derek unintentionally offends Odette, who then refuses to marry him if he can't prove that he loves her for who she is and not just her beauty. Odette and her father are then attacked by Lord Rothbart, a vengeful sorcerer who was cast out of William's kingdom when he plotted against the king. In the form of a beast, Rothbart mortally wounds William, and kidnaps Odette then places her under a spell. Now it is up to Derek to rescue Odette by showing his undying love. But will he be in time?
