A very ordinary man (Nao Omori) who takes care of his son while his wife lies in a coma, enters a very ordinary building. Following a seductive ride on a merry-go-round, he signs up with an exclusive club. Membership is one year only and cannot be cancelled under any circumstances. Happily he endures dominatrix intrusions in his daily life, until they get a little too close to his unsuspecting family. With a courage not displayed in his professional life as a bed salesman, he tries to cancel his membership, evoking the wrath of the American CEO, who descends upon Tokyo to teach him a lesson.
