Across the Inagawa River that runs through the center of the village, the children of the two villages scrambled for a swimming pool, and each time a stone battle took place. Takemaru, the only son of the priesthood of Tada Shrine, was weak and was always forced to carry stones. However, neither swimming nor stone-throwing was a secret to his sick mother, Kouko... Seishi Matsumaru, Ryuichi Yoshida, and Ado Matsuyama were adapted from "Tenmangu" and "Ishigassen", directed by Mitsuo Wakasugi of "Waran Hayashi", and photographed by Hanjiro Nakazawa of "The Last Women".
