In 1970s Japan, the life of a seemingly normal couple turns into a whirlwind of hidden desires and forbidden temptations. Hiroshi, a deeply committed family man, begins to feel that his married life has become monotonous and devoid of excitement. Everything changes when his wife, a young and beautiful woman, becomes the object of desire for a mysterious and seductive stranger who crosses their path.
As the tension mounts, Hiroshi is compelled to confront his own repressed desires and his inability to satisfy his wife. Their relationship is put to the test when she begins to explore her sexuality in a freer and more provocative way, leaving Hiroshi caught between jealousy and curiosity.
With a bold focus on the exploration of love, desire, and betrayal, the film not only examines the limits of fidelity but also reveals the deep insecurities and yearnings of its characters. As the plot unfolds, the decisions each of them makes trigger a cycle of passion and despair that will culminate in an unexpected twist.
This film is not only an exploration of eroticism in Japanese cinema of the time but also a reflection on the complexities of modern relationships and the imperceptible passage of time that can consume what was once true love.
