Sasakawa and his wife, Miyako, who live in a local city near the Kanto region. My son went to a university in Tokyo and lived alone at home. One day, Miyako's younger sister Sakiko arrives for the first time in a few years. Miyako is going to have hernia surgery, so she came to take care of her surroundings. Sasakawa involuntarily spit on Sakiko's body after a long absence. And after his wife went to the hospital, Sasakawa set up a camera for voyeurism borrowed from an acquaintance at home, but he began to look into Sakiko's appearance.
