Plot
The story starts with that of an aging king, named William (Dakin Matthews) while he is well-loved, he's very saddened as he has yet had an heir for his kingdom. However, soon he's given a daughter and names her Odette. He holds a big celebration and invites many from different kingdoms, including his friend the widowed Queen Uberta (Sandy Duncan) and her young son Prince Derek. While watching the young prince happily interact with the infant princess, the widowed king and queen think upon the same idea. They decide to have the children meet every summer, with hopes that they would fall in love. However, the evil sorcerer Rothbart can be seen in the back. He cares little for Odette's birth, but he desires King William's throne and kingdom and planned to attack using "the Forbidden Arts." But on the eve of his planned assault, King William's soldiers attacked and destroyed his dark magic. Despite warnings, King William merely banishes the sorcerer. As he's banished, Rothbart vows loudly to William that he will take everything he loves and owns for himself. While many feared King William's mercy, everyone soon forgets the threat and prepare for the age of when Princess Odette and Derek would meet. The story then focuses on the children during their first play date for the summer.
