Aya (Tsubasa Amami) married her senior from university, Shinji, and was enjoying a fulfilling life as a housewife. One day, the shower at home broke, and she asked Nakamura, a plumber who was a colleague of her husband and also her senior, to repair it. Nakamura harbored jealousy and feelings of inferiority toward his colleague's happy family. Taking it out on Aya, who resisted, he forcibly assaulted her. Aya was deeply pained toward her always-considerate husband, but gradually Aya's body was taken from her.
