Nonoka Yukari enters a captivity escape game in which she must break free before the deadline while men deliberately obstruct her. As a masochistic porn actress known for extreme bondage play, she initially appears capable of enduring every erotic distraction and winning. She never had a chance.

Nonoka says the ordeal pushes her physically and mentally to the limit and makes her cum again and again.
