Goda Saburo lives in a boarding house in Asakusa, Tokyo. Her biggest fetish is going up to the building’s rooftop to spy on the lives of other tenants, especially Minako's living room window, where she and her mistress practice a strange game of sexual domination. When realizing that she is being observed, Minako becomes even more excited and performatic. Goda, in turn, is embarrassed, and decides to direct her attention to a different window. Her new object of observation is a painter dressed in animal skins engaging in sex with her lover. In another room, a man sleeps.
