Asahina and her husband have been carefully preserving the inn passed down from their predecessors, but declining business due to economic hardship, combined with the increasingly hostile behavior of their employee Suzuki, has deepened their troubles. One day, the situation worsens when Suzuki's loan shark, Shijo, arrives demanding immediate repayment. Desperate, Suzuki makes a dangerous decision—offering up Karen, his beautiful, busty young employer, as collateral. As a result, Karen is sexually exploited by both Shijo and Suzuki, enduring intense suffering as her ordeal unfolds.
