Rui, the young proprietress of a hot spring inn left behind by her father, finds herself in escalating conflict with the Yabuta Group, a corporation pushing resort development. One day, she is violently taken by a masked man full of vigor, marking the beginning of days spent being trained and dominated by yakuza and delinquent schoolgirls. Eventually, she is forced to perform humiliating shows for the inn's guests, her increasingly exposed and degraded appearance drawing more and more attention.
