Jiro, a young yakuza, and Mami, a diplomat's daughter, are two young lovers from different worlds. Having met by accident, they soon discover a new life together. But their love is ill-fated. Mami's family will not accept her choice, while leading an honest life seems like an unattainable goal for Jiro. Can there be anything else but a tragic ending? Shinji FUJIWARA's novel delivered the classic plot for this box office hit, which for the first time brought together Sayuri YOSHINAGA and Mitsuo HAMADA as one of the iconic couples of Japanese cinema.
