Elite narcotics investigator Hikaru Miyanishi, a woman of beauty and intelligence, infiltrates a drug trafficking organization's headquarters, only to be suddenly overpowered by a man under the influence of an aphrodisiac who takes control of her body. Caught off guard in an instant, she becomes his prisoner, stripped of her freedom and used as a test subject for aphrodisiac drugs. Though she clings to the hope that her comrades will rescue her in two hours, she is subjected to relentless humiliation under tight bondage and the effects of potent drugs—violent orgasms, gang rape, deep-throat facials, and more. Hikaru endures with fierce mental strength, but as the repeated rope restraints and aphrodisiac conditioning take their toll, her mind and body begin to transform. Her emotional turmoil and psychological struggle are vividly portrayed, revealing a new, altered version of Hikaru.
