The film is divided into three distinct segments, each named after a dish and centered around a specific sexual or psychological complex. All three episodes are linked by the recurring character Kurita, a shabby, unsettling man who confronts each protagonist with a secret that exposes their repressed desires. ; Natto Enatsu (Ryo Ikeda), a designer leading a sexless married life, is approached by a strange man named Kurita (Tateto Serizawa), who claims to be investigating an extramarital affair involving Enatsu's wife Megumi (Manami Hashimoto). Over the course of their conversation, Kurita vividly describes Megumi eating sticky
natto, turning the act of eating into an erotic performance. As the details grow increasingly intimate, Enatsu's jealousy and frustration surface, and the image of natto becomes a catalyst for unearthing his suppressed desires and anxieties about his marriage. ; Mapo Tofu Akane (Honami Satō), an office worker suffering from depression and panic attacks, is trying to overcome a crippling fear of driving after a past incident. Kurita inserts himself into her life by recounting an episode in which she nearly ran him over with her car, using the incident to taunt and manipulate her. Through a charged sequence involving the preparation of intensely spicy
mapo tofu for her husband (Mukau Nakamura), Akane's bottled-up rage and latent sadistic impulses are brought to the surface, shifting the power dynamic between her and the men around her. ; Ramen Ikeyama (Shogen), a married advertising executive, maintains an affair with his younger lover Momoko (Rina Takeda). Hoping to end the relationship, he cancels a planned meeting with her. Kurita then calls Ikeyama, claiming to have abducted Momoko and describing in graphic detail how aroused she was while eating an extraordinarily greasy "back-fat"
ramen with extra garlic. As Ikeyama slurps through his own bowl of ramen while listening to Kurita's narration, feelings of guilt, lust and gluttony become intertwined, driving him back toward an encounter he had intended to avoid. == Cast ==
