In a quiet town on Reiko Hyodo, a young woman who has a limp in her left arm from a childhood joint inflammation, lives with her widowed father and her grandmother as part of an amateur theatre troupe. The everyday rhythm of small-town life—the creak of wooden floors, rehearsals under studio lights, and the hush of snow-filled streets—frames her world and her quiet longing. She shares this home with the warmth of family and the companionship of the troupe, where performance offers a temporary escape from the loneliness she sometimes feels.
Her life takes a dangerous turn when she begins a passionate affair with the much older, married architect Setsuo Katsuragi. The relationship pulls her into a secret that disrupts the harmony of her small circle and unsettles the boundaries she’s known. Katsuragi’s wife, Akiko Katsuragi, has her own tangled history, having maintained an ongoing affair with medical student Tatsumi Furuse, a man whose fixation on her becomes a consuming obsession and who resists any notion of ending their relationship. This web of desire, secrecy, and resentment begins to ripple through Reiko’s world in unexpected ways.
Intrigued by Mrs. Katsuragi, Reiko manages to make personal contact with her, and the two women gradually grow closer. What begins as curiosity deepens into a complex bond that blends elements of surrogate motherhood with a troubling and undeniable attraction. For Reiko, the connection with Mrs. Katsuragi intensifies the sense that she is incomplete—caught between the allure of the older woman and the tainted loyalty to the man she loves. As her feelings spiral, she confronts Katsuragi, accusing him of offering pity rather than sincere love, a plea that exposes the fragility of their fragile arrangement.
When Reiko finally shares the truth of the affair with Mrs. Katsuragi, the elder woman responds with restraint rather than anger, choosing not to scold or condemn. Yet the revelation sets off a chain of consequences that neither woman can control. Mrs. Katsuragi’s reaction—whether born of despair, guilt, or the weight of the situation—leads to a final, tragic act: she commits suicide. The loss leaves Reiko reeling, and she returns to the couple’s home with a cautious distance from her former lover, avoiding any direct confrontation.
Ultimately, Reiko withdraws from that turbulent chapter of her life and re-enters the world she knows best. She joins the theatre troupe as they embark on a trip to an out-of-town stage show, finding a fragile relief in leaving the past behind and returning to the art that has long anchors her. In the end, the performer in Reiko clings to the hope that moving forward—through performance and distance from the heartbreak—may offer a path to healing, even as the memory of what transpired lingers like a quiet echo in the wings.
