Known for its strict, Spartan-style education, a prestigious academy has been plagued by a series of bizarre incidents, with students dying or going missing one after another. To uncover the truth, a female investigator is forced to go undercover, disguising herself as a schoolgirl and infiltrating the institution. Behind the school's facade lies a shocking secret: the female principal is an extreme enema fetishist. She brainwashes students with twisted compulsions, then gathers them each night in a hidden torture chamber beneath the campus for grotesque "enema parties." The investigator's cover is eventually blown, and she too is dragged into the nightmare, subjected to the same humiliating enema punishments in a shocking turn of events.
