The sound of quiet waves. Glittering water surface. The shadow of a woman frolicking on the beach. A mother, Shinobu, and her son, Yasuhito, come together for their annual family trip. Yasuto was a little nervous about traveling without his father who couldn't come because of work, because he had fallen in love with Shinobu from the first time he met his new wife. Playing with her mother at the beach, taking a bath with her at the inn where she's staying... While doing so, Yasuto's feelings for her mother exceed the limits of his patience, and that night he attacks Shinobu.
