Demetan comes from a family so impoverished that he cannot even attend school in his woodland pond community. However, he has a friend named Ranatan, the lovely, kind frog girl who is the daughter of the pond's wealthy ruler. Naturally, her father is quite displeased by this relationship and tries to break it apart. Yet the young frogs continue on with courage and confidence, not only to live their own lives but also to guide the heartless leopard frog toward a sense of justice and generosity. Gradually, the pond community responds to their sincerity and joins them in a march toward a bright future.
