Machiko had inherited shares in the major corporation once led by her late husband—who had been the company president—and was living a carefree life with a younger lover. Concerned about her behavior, company executives tried to arrange a marriage for her. At a loss, Machiko consulted Rie, an instructor at a kimono-dressing school, and set a plan in motion: she hired a private detective agency to investigate her own conduct and checked into a hotel with Rie. Rie, a lesbian who had long suppressed her desires and lived a life of sexual unfulfillment, seized upon the situation to initiate a sexual relationship with Machiko.
