Yuriko's husband, Koji, is a deep-sea fisherman. She was home only ten days a year, and Yuriko felt lonely. Her son Tatsuya was worried about his mother, but he couldn't stand the desolate fishing port town and was thinking about leaving for Tokyo. Meanwhile, Mamoru, a fisherman from the fishermen's cooperative, occasionally visits Yuriko's house with fish. He thinks about Yuriko, but Koji can't lift his head and is in a state of frustration, but he can't stand it and attacks Yuriko. Tatsuya, who knew about it, also explodes her desire for Yuriko. It was Yuriko who couldn't accept Tatsuya's desire.
