Fumie Sugimoto, a beautiful mother, lives with her shut-in tyrant son. It's been a year since he stopped attending school. The mother is trying her best to rehabilitate her son, but he continues to refuse to go to school.

Rope straddling strong incest, depicting the anguish of a mother who is forced to straddle a rope while suffering.
