Karen Yuzuriha stars in her first full-scale undercover-investigator humiliation drama. Searching for a relative who vanished after getting involved with aphrodisiacs, Karen infiltrates as a nurse and investigates alone. The enemy takes her relative hostage, captures her, and subjects her to powerful drugs and forced pleasure that overwhelm her pride and duty. She squirts uncontrollably, loses herself in vacant-faced orgasms, and climaxes deep inside as she is repeatedly creampied, leaving her mind and body shattered by the drug-fueled assault.
