Elevator girl "Azumi" gets caught in a sudden incident during her daily routine. Trapped with no escape, she is repeatedly forced and assaulted against her will. With no way to call for help or leave the sealed room, the rape continues as her sanity gradually breaks down, eventually leading to complete confinement. Her cries for help echo inside the elevator, but in this isolated space where no one can enter or exit, gang rape is repeatedly inflicted upon her.
