A janitor working at a prestigious women's university is actually a pervert. He secretly installs hidden cameras in the women's restroom—a place everyone believes to be safe—and records girls during their private moments. He then uses the footage to carry out his twisted schemes. His ultimate plan? Confining the victims inside the restroom and subjecting them to torture. Featuring five different types of female college students: a cute-faced older sister type, a busty I-cup college girl, an exhibitionist pervert who orgasms so hard she rolls her eyes back, a shy H-cup big-breasted girl, and more. Hidden within are sinister, psychologically disturbing setups that shatter the sense of daily security.
