Ritsuko, 52, and Kaori, 56, who travel to Ali, spend a crazy night in a remote hot spring inn with young people who met on a trip. Ritsuko superimposes the image of her son-in-law who died suddenly on a young man and goes mad in agony with a pseudo-mother-child relationship. Kaori of super breasts asks for insertion every time she runs out in a dense play with a young man who is good at sexual intercourse, and indulges in a greedy relationship. The secret meeting that six middle-aged women in their 50s and 60s fascinate gives middle-aged men and women courageous energy.
