It is Yoon’s birthday and all she wants is a jump rope so she can play with the other girls in the school yard. Instead, Yoon’s mother gives her a Korean storybook about a silly girl who is tricked by a tiger. Yoon also receives a jade bracelet that once belonged to her grandmother. The next day at school, a girl offers to teach Yoon how to jump rope, but for a price: she wants to borrow the jade bracelet. When Yoon tries to get her bracelet back, the girl swears it belongs to her. Yoon must use the lessons learned in her storybook and her “Shining Wisdom” to retrieve the precious keepsake.
