Beautiful teacher Reiko once suffered trauma from rape, but now at her new workplace, she finds herself falling into evil hands once again. Just one month after transferring to a high school where her former mentor serves as principal, she attends a welcome party where her beer is spiked with a special sedative, leaving her completely defenseless. The perpetrators are none other than chemistry teacher Igawa and the principal himself—unthinkable figures to orchestrate such a crime. While Reiko lies unconscious, they rape her helplessly and record the entire act to use as blackmail, subjecting her to unbearable humiliation. This act of degradation spreads a new darkness across her life, as her despair and terror become the central focus of the story.
