Under the pretense of helping women suffering from molestation, lawyer Kito has set up mock train cars and examination rooms inside his law office to "collect evidence." However, this is merely a facade—his true intention is to reenact the assaults, exploiting the victims' humiliation to bring them to orgasm. One after another, women come seeking help: an office lady with a gorgeous ass who was groped on a train, a schoolgirl, a big-breasted young married woman victimized by doctor harassment—each drawn into his fraudulent "evidence gathering." Tormented by shame and anxiety, the women gradually grow wet, their rising arousal fueling Kito's escalating depravity.
