Minto Suzuki is a young married woman whose husband has requested that she be trained to become obedient. Strangers enter her life and suddenly begin to open up her body. These men teach her pleasure by forcing her to masturbate, making her perform blowjobs, and tormenting her sexually. As she endures their treatment, she's promised a reward: a threesome with the men if she behaves well. Using a mix of rewards and punishment, they condition Minto through pleasure and pain. Eventually, the day comes when the trained wife is to be returned to her husband—but she rejects him, and one final session of discipline by the men is about to begin.
