A story of forbidden desire and longing set in the Showa era. Reiko's husband falls gravely ill, requiring expensive medication that her limited finances cannot cover. Desperate and helpless, she is approached by a corrupt broker who whispers, "If you have no money, you can pay with your body." Torn between guilt and love, Reiko tearfully makes her decision. Known as the "passionate widow," she runs a traditional flower arrangement class, but now faces dire economic hardship—unable to even afford teaching materials. To raise money for flowers, she offers her body to a florist. Into her troubled life steps a young man who attends her class and gradually falls in love with her. The story portrays a woman's inner turmoil as she wavers between love and sin, emotion and desire.
