Rinko, the wife of an easily irritable, reputable doctor and Shoichiro, a veteran newspaper reporter have made choices in the course of their lives so that their future seems to have been fully established. Both are stuck in a little job that appeals to the imagination and a blissful marriage. Everything changes on the day they meet by chance and fall in love immediately. Together they find the passion no longer present in their marriages. The fire in their hearts has been extinguished and has given way to chill. They forget all grayness in each other's arms and the more often they come together secretly, the stronger their desire becomes. The hours they can not spend together seem like days. However, the intrusive moral laws of Japanese society do not offer a place for their passion. With every kiss, the shame increases, after every banned love night the blame is greater again, until they finally have only one way left to be together.
