Unlike many Giallo films, Antonio Marghetiti's Schoolgirl Killer hardly features any of the blood, sex and general sleaze that have made the genre famous, and instead puts its focus on the murder mystery and central set of characters. In fact, it's amazing just how restrained this film is, considering that it is set in an all-girls school and how almost every Giallo film with a similar setting takes full of advantage of this. The director does an exquisite job of presenting his story and his setting, and the film features some stunning camera work, which beautifully captures the well designed sets, and the fashion sense of the girls at the college. The film begins with a murder in which the killer strangles a woman and has the body put into a trunk which is then delivered to an all-girls school. Shortly thereafter; Betty-Ann, a student at the school is murdered in the basement, and when another young girl is killed in the shower, the police, led by Inspector Durant, are called in. And they're not the only ones on the case, as amateur detective Jill is also investigating.
