In a fictional Taisho-era village ruled by a cruel, archaic custom, a poor adult woman is shunned as impure and struggles to avoid exile. When famine strikes, the men revive an old ritual and choose her as a sexual sacrifice, using her desire for acceptance to turn her into their sex slave. Day after day she is forced to serve the villagers, gang-fucked, made to squirt, and passed from man to man with no one willing to save her. She believes refusing sex will cost her place in the village, but repeated pleasure gradually overwhelms her resistance. The abuse becomes routine, she grows increasingly lustful, and the village eventually comes to see her as indispensable.
