"Help me..." A merciless outdoor gang rape of a young girl. Unreasonable humiliation and abnormal confinement awaken her masochistic Kokoro. Unreasonably used as collateral due to her parents' debts, the girl is locked alive in a drum can, treated like an object and Kokoro is eaten away by the daily interest payments... In the drum can that has become her home, numerous humiliating acts are performed, and her body and mind are violated under 24-hour strict surveillance. Although she begs for forgiveness, her overly sensitive big breasts are forced into a lewd sexual act with a forced orgasm, and her big breasts are tortured and stabbed. Where did she go after this...?
