Demetan hails from such a destitute family that he is unable to attend school in his woodland pond community. However, he has a friend named Ranatan, a lovely and gentle frog girl who is the daughter of the pond's wealthy ruler. Naturally, her father is quite displeased by this relationship and seeks to break it up. Nevertheless, the young frogs continue with courage and confidence, not only to live their own lives but 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.
