This kinky soft-core melodrama from veteran Nikkatsu director Shogoro Nishimura deals with overprotective siblings, abortion, and not so subtle intimations of incestuous longings. Comedian Mirai Kiuri is the jealous young man who can't stand anyone moving in on his pretty twin sister (Akiko Hyuga). When his friend Yagi (Kiyoyasu Adachi) starts dating his sister, and gets her pregnant as well, the stage is set for fights, arguments, and alienation -- all in the pinku eiga genre's grandest soap opera tradition. Junko Miyashita co-stars.
