In the film, Aika Yumeno plays an investigator who, acting on intelligence, goes undercover to investigate a laboratory that manufactures aphrodisiacs to induce female arousal. Disguised as a researcher, she initially puts on a convincing act, even personally testing the aphrodisiacs and having sex with one of the researchers.
However, Aika Yumeno's identity as an investigator is quickly exposed. To complete the mission, she dons a tight-fitting leather jacket with a plunging neckline and threatens the researchers with a gun, demanding they hand over the aphrodisiac formula. But as the saying goes, "the mantis stalks the cicada, unaware of the oriole behind," the prepared men ambushed Yumeno Aika from behind, quickly defeating her and drugging her.

After being drugged, Yumeno Aika began to hallucinate, and her body became increasingly sensitive. She kept saying she didn't want to think about it, but the urge was overwhelming. Finally, under the drug's effects, she completely transformed into a shameless submissive, not only being imprisoned and tortured by the enemy, but also being penetrated until she convulsed, collapsed, and lost control of her bladder.

Although the plot of the investigator is always the same—failed infiltration and ultimately raped by villains—watching the usually glamorous goddess captured and bound by the enemy, desperately begging for mercy, and then struggling in agony, is still very moving no matter how many times you watch it!
