At a high school steeped in sexual depravity, the boundaries between students and teachers become too blurred. Male students steal kisses from female teachers, and the principal even arranges for his friend—a perverted doctor—to conduct body inspections on the female students, resulting in utter chaos. One day, after escorting an inebriated, beautiful teacher home, a male teacher turns into a "pickup guy" and ends up assaulting her in front of her beloved cat. Meanwhile, male high school students get involved with a nurse at a hospital run by the perverted doctor—again, with her pet cat watching—and later they even throw orgy parties at their homes with female students. As a result, pubic lice infestations break out among the students, and, inexplicably, the teachers become afflicted as well. Thus, the pubic lice debacle erupts! Who is the culprit behind this mayhem?
