Asahi Mizuno is a stunning exhibitionist woman with a secret identity: an undercover female agent infiltrating a radical organization. Captured by the group's leader, she is stripped naked outdoors, tightly bound, and subjected to relentless brainwashing. As she nears the final stage of gaining the organization's trust, her true identity is exposed. In that instant, she endures vicious, sadistic torture and is completely brainwashed. Now reduced to a sex slave for the boss's desires, she begins a new life of forced servitude, using her prized body to serve the organization as a living sex toy.
