The proprietor of the public bath "Oibore", Umezo Shochiku, is perverted at heart. He always enjoyed voyeuring the women's bath with his perverted companion Zakuro. A young wife, Kaori Yuasa (Riko Honda), lives in the neighborhood of such a suspicious public bath. Umezo wanted to make her a neat and clean face with a nasty plump scent. One day, Zakuro brings a bath salt with the words "Tanjunyu" written on it. It seems that any woman can turn into an obscene female... Immediately, Umezo breaks down the bath at Kaori's house and tricks her into going to the public bath.
