What Happens in Nanami: The Inferno of First Love: Full Plot Summary

The whole story of Nanami: The Inferno of First Love (1968) explained, from the opening scene to the final frame: every key event, every twist and what it all adds up to. Read it as a quick recap before the sequel, to check a scene you missed, or to finally understand what really happened.

Nanami, Kuniko Ishii, a nude dancer, and her friend Shun, Akio Takahashi, who is still a virgin, rent a room in a love hotel. He cannot consummate the moment, but Nanami remains understanding, choosing patience over frustration as their night unfolds. They drift into quiet conversations that let them reflect on their pasts, sharing fragments of how they arrived at this room in Tokyo’s nightscape. Nanami explains she left Shizuoka for the big city, taking up dancing because her previous job didn’t pay enough to survive, while Shun opens up about a childhood shadow—he was left by his mother and has grown into a man who now works as a goldsmith in his stepfather’s workshop.

Flashbacks deepen the story, revealing the deeper wounds that shaped Shun: a history of repeated sexual abuse by his stepfather. The revelation adds weight to the tenderness and fragility of his relationship with Nanami, casting their intimate moments in a more emotional light than mere desire. The film threads these memories through the present, showing how past traumas echo in the couple’s current attempts at connection, trust, and closeness.

Complications arrive when Ankokuji, a customer of Nanami, Minoru Yuasa, talks her into participating in photo shoots that explore lesbian sadomasochism and erotic catfights. The shoots are staged in a circle of red-light district clients and watched by yakuza, creating a charged atmosphere that blurs the line between art, commerce, and danger. Shun, who first witnesses a photo session and feels a surge of jealousy, confronts Ankokuji and Nanami, demanding answers and perhaps a sense of restraint from the disturbing engine of this world.

Ankokuji attempts to justify his interest as something born from a loveless marriage, suggesting that his attraction to Nanami is more about filling a void than about authentic affection. Nanami, however, later encounters him with a seemingly ordinary family life—an image of harmony that clashes with the earlier, unsettling dynamics she had witnessed. The encounter leaves her shaken and disappointed, caught between the allure of money, fame, and a partner’s complicity in a cruel social game, and the desire for something more sincere and stable.

Despite the tension and danger, Nanami and Shun press forward with their relationship, continuing to see each other and arranging another appointment in the same hotel room where their confidences had first deepened. Their bond is tested as the outside world intrudes with threats, manipulation, and the lure of a night that can never fully be contained within the walls of a room.

The danger finally closes in when Shun is intercepted on his way to the hotel by Ankokuji’s former red-light district associates. They press him to reveal Nanami’s whereabouts, a confrontation that forces him to flee. The pursuit ends in tragedy as Shun is fatally struck by a car, a sudden, devastating turn that shatters Nanami’s fragile sense of safety and control. In the aftermath, Nanami waits in the hotel apartment, the sounds of the street leaking through the walls. She hears voices outside, and when she opens the window, she confronts the stark, heartbreaking sight of Shun’s body lying among the passers-by—the harsh clarity of mortality and the fragile line between longing and loss.

This film weaves together themes of vulnerability, power, and the ways people seek connection in a world full of compromise. It moves from intimate, quiet moments to shuddering shocks, all while maintaining a restrained, observational tone that keeps the focus on the characters’ emotional landscapes. The result is a slow-burn narrative that treats its protagonists with a compassionate seriousness, never shying away from their pain, yet always returning to the humanity that keeps them moving through the night.
