Miyu Kanade is dominated by an older man who controls her body against her will. Her days are like those of a captive, completely stripped of freedom. But when the man vanishes due to debt, she falls into the hands of a group of women. Bound tightly, subjected to nightly assaults, forced mouth-to-mouth feeding, nose hooks, bean squeezing, gags, spanking, spread-eagle suspension, breast milking, upside-down hanging, hot wax torture—she is exposed to intense lesbian S&M. Gradually, something begins to awaken inside her. She can no longer remain a mere prisoner. Something within her is starting to change.
