Fabio Testi is the gym teacher at a Catholic school for girls in London. During an amorous escapade with one of his students, she suddenly freezes, claiming to have seen a murderer from the corner of her eye. He later ...展开learns from the media that the young student’s corpse has been recovered. Curious, he visits the site and immediately becomes a police suspect. Other victims follow, brutally assassinated by way of repeated knife stabs to the vagina. All of them were students in the same Catholic school. An elegant giallo by Massimo Dallamno based on the story by Edgar Wallace. Despite the themes of exploitation, this film is a class beyond the genre. Beautiful, obscure images by –surprise!- the master of debauchery Joe d’Amato. Ennio Morricone provides an excellent soundtrack that takes us from searing female screams to gentle piano melodies, passing through atonal lines.
