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.

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?
