Two Nikkatsu stars, Yujiro Ishihara and Ruriko Asaoka, take part in an inexhaustible and unpredictable game of love behind the backdrop of Yokohama City. Notably inspired by Hollywood films, "A Warm Misty Night" offers a captivating, almost un-Japanese world of film. Ruriko's stellar presence on the silver screen can be compared favorably to Ingrid Bergman in "Casablanca". The poignant scenes, well established characters and memorable quotes, solidifies this film as one of the greatest romance action movies in Nikkatsu history.
When Toru Sagara (Yujiro Ishihara) returns home from a foreign cargo route, he proposes to his beloved girlfriend Akiko (Ruriko Asaoka). She joyously agrees, promising a life together. On the day they were to be joined in matrimony, Akiko suddenly goes missing. Toru waits hours for her to show, but he is only greeted by the darkness of night. Four years later, his fiancée turns up at a night club in Yokohama with another man.
