After his masochistic wife was seduced and ran away, a man began plotting a misguided "revenge" on the happy married woman... a vengeful SM trainer known as "Yamio". He rents out his house and lets young couples live there cheaply, awakening the masochistic side of the wife and seducing her... "Yamio" is a professional trainer who has already awakened the masochistic side of 16 married women. Who will be his new prey?
