Special investigator Kana, while tracking a drug trafficking ring, is kidnapped as a substitute for her junior partner. A year later, a disc sent from him contains shockingly extreme footage that leaves viewers stunned. Her throat is violently penetrated by a thick cock, and under the influence of aphrodisiacs, she is raped, gang-raped, yet overwhelmed by pleasure, gushing fluids as she reaches climax after climax. To her junior, the images reveal Kana—the once-proud officer—now completely broken into a sex slave, enslaved by drugs and ecstasy. Her transformation becomes the key to uncovering the truth behind her disappearance.
