Plot

Deep in the mountains of Japan a dam is scheduled to be built, thus forcing a relocation of the farmers. One of them is 78-year-old Denzo, whose son and his wife consider him senile. Left alone, he befriends a young boy, Sentaro, who has heard that the old man was once a great angler. The unlikely pair spend lots of happy time together, until Denzo has a heart attack and dies far upstream. The dam is completed and the entire area is inundated. Everyone will move away, except Denzo.
