Chisato is 47 years old. One day, a man claiming to be her son's friend threatens her, saying, "I heard you and your son were into incest in the outdoors. I want you to do it with me too." Five years ago, Chisato was developed into a masochist by her son's friends, and three years ago, she was in a training relationship with her son. She is trained in the garden of her home and in the young man's room... This work is a valuable five-year video record that captures Chisato's outdoor training from five years ago, three years ago, and now.
