Makoto Katagiri (Yasunori Ishizu) is a 30-year-old man living with his mother Miyo (Hiroko Fuji), who operates a pornographic photography business specializing in
sadomasochistic content out of her combined home and adult toy store. As a child, Makoto shot and killed a black American soldier whom he found having sex with his mother. The incident left Makoto psychologically stunted as well as
impotent, and as such his mother and her staff treat Makoto much as a child. Despite this, Makoto has developed a strong interest in S&M, though he has no outlet for his interests. Senzô Tôyama (Nagatoshi Sakamoto) is the elderly owner of the company Makoto works for, and also has an interest in S&M. However, his new wife Shizuko (
Naomi Tani) refuses to let Senzô tie her up or even watch her bathe; instead he vents his frustrations and needs on their housemaid Haru (Hijiri Abe), forcing her to indulge in his kinks. After finding some bondage pornography in Makoto's desk, Senzô summons him to his home, where he first asks, then orders Makoto to kidnap and "train" his wife in order to break her pride so that she will submit to his desires. After some hesitation, Makoto agrees. While in town, Senzô drugs Shizuko's tea with sleeping pills, allowing Makoto to leave with her in his vehicle. On the way home Makoto stops in a field and attempts to
rape the semi-conscious Shizuko, but his arousal brings on a hallucination of the soldier he killed, forcing him to stop. At home, Shizuko awakes to find herself tied up and calls for help, attracting the attention of Miyo. Rather than helping the woman, Miyo seems pleased at her son's actions, and encourages him to rape Shizuko. When he says he can't because she is too beautiful, Miyo suggests Makoto give Shizuko an
enema to overcome that impression. He does, and after watching her expel it finds he is able to become aroused without issue. Makoto rapes Shizuko while his mother listens outside his room. Makoto reports his progress to Senzô regularly, providing tapes and even physical evidence of his wife's continued "training". However, he also finds himself becoming attached to Shizuko. Makoto returns home one day to find Miyo and her staff have been torturing Shizuko while he was at work. He orders them off of her angrily, telling them not to touch her unless he is present. Shizuko finds herself becoming more at ease with her situation and with Makoto, and later asks him if he will protect her; he says yes, going on to say he wants to spend the rest of his life with her. Makoto tells Miyo this, and when she objects he responds angrily, calling her an old hag. One day Makoto returns home to find Shizuko tied up and being used by the black soldier from his dreams. He recoils in horror when the man rises to attack him. Miyo then steps in and pays the man, revealing that she staged the scene with a look-alike to render Makoto impotent once more. Makoto tries to have sex with Shizuko again, despairing when he finds that his impotence has returned. Despite this, he keeps training her, even taking her outside for a walk. Taking a chance, he unties her so that she might use the restroom; after a long, worrying delay, Shizuko returns, to the delight of Makoto. Later the two go to watch a
pornographic film, which features a black man who resembles the soldier from Makoto's dreams. Uncomfortable at first, Makoto starts to remember his childhood incident in detail, eventually remembering that it was Miyo who shot the man, not him. Overjoyed, Makoto calls his mother from a public phone booth to tell her he has remembered the truth, letting her listen as he has sex with Shizuko during the call. Finally, Senzô arrives to reclaim his wife. Makoto is surprised when Shizuko moves to her husband's side eagerly. He asks her to divorce him so that they might marry, but she refuses, saying that she is now happy since Makoto made her a "total slut" just as her husband wanted. However, she offers to let him come with the two of them, and though hesitant, Makoto agrees. Miyo begs her son not to go, but the three pile into Senzô's vehicle and leave, a distraught Miyo running after the vehicle in vain. The film ends with Shizuko bound, being ravaged simultaneously by Senzô and Makoto while Haru watches in shock. == Cast ==
