My Husband's Friend Mao lives with her husband and childhood friend, Ichiro, in a small countryside village. Ichiro works hard to revitalize their ageing, declining village, and Mao supports him the best she can. The couple lead a rather happy life; however, one day, a man in a suit appears and introduces himself as a "local development partner". His name is Oki, and he is a good friend of Ichiro's. He had moved to the city, but this time he is back to betray both his home town and his best friend: not only he has his own sinister plans for the future of the village; he also used to have feelings for Mao, and he starts fondling her body right before Ichiro's eyes....
