Nine-head-tall beauty Mitsuha Ashitaba stars in a full-scale cuckold drama directed by married-woman specialist Hiroyuki Kimura. Advertising employee Seiichi lives happily with his former-model wife Mitsuha until his boss Tabuchi orders him to arrange an underground fashion show where nude male and female models entertain the audience. Seiichi assumes the request is a joke and hires nobody, enraging Tabuchi, who commands him to use Mitsuha in the next show. She has coincidentally considered returning to modeling, so her regretful husband persuades her. On the day, events strip her nude and press her against male model Saji, revealing eroticism suspended between humiliation and liberation.
