In my home, which runs an orphanage, lives my mother along with two male classmates. She always treats me kindly, and I harbor complicated feelings for her. One day, Yoshida, a troubled boy, returns once again to the orphanage. Later, Yoshida gathers us together and suggests showing us a videotape he recorded. When we play the tape, a shocking scene unfolds before our eyes—my mother willingly submitting to and enjoying the sadistic sexual demands of her domineering husband.
