A masterpiece of delicate, profound human eroticism by the genius director Gunji Kawasaki. Set in a quiet lakeside near Tokyo, it portrays the daily life of a family operating a sightseeing boat. The female head of the household exudes constant sexual allure, and in a shocking turn of events, after finishing sex with her husband, she spreads her legs even for her father-in-law who has been secretly watching. A unique worldview that sharply depicts human desires and relationships.
