A stranger comes to a fishing village, which plans to catch lots of fish through poisoning the river.  As the villagers debate, they are warned against this by a traveling priest. A fisherman saves a little turtle and is taken to an undersea palace. Two boys go to ask the fire god to help them with a demon who's been raiding their village.
The demons were sealed in the rocks
Los demonios encerrados en la roca,
Los demonios, atrapados en la roca,
Os demônios foram selados em pedras
