Son's friend Yuichi bullies a neighborhood boy, Takashi, injuring him. Taking responsibility, mother Noriko (Natsuko Kayama) visits Takashi's home to apologize. However, Takashi immediately gropes Noriko's body, forcibly drawing pleasure from her. Though she tries to endure it as mere children's trouble, Noriko's body awakens long-forgotten feminine instincts. Later, when Noriko visits Takashi's house again, she encounters Takashi's mother, Kaoru (Chisato Shoda), completely dominated by her own son. Shocked by the sight, Noriko gradually falls under the twisted mother-son pair's influence, transforming into a depraved sow. This story unfolds a bizarre dynamic deeply entwined with mother-son relationships, depicting a shocking metamorphosis.
