Elite narcotics investigator Aoi Mizuta, played by Eru Shiina, has hated drug crime since childhood because of her official father. While pursuing the Black Lion Society, which floods the streets with illegal drugs, she is captured and injected with the same powerful aphrodisiac she was investigating. The gang subjects her to brutal pleasure torture, pushing her trained mind and body toward collapse. Humiliated by uncontrollable orgasms and convulsions, the nearly unconscious investigator has her hidden submissive side forced to the surface as her fate hangs in the balance.
