Second in Dallamano's schoolgirls-getting-killed trilogy, it's not as good as Who's Next? (Solange) but not bad in its own right. The killer is someone who rides a motorino (hey, it is Italy!) and never takes off his/her riding helmet, ala Magnum Force, the 2nd Dirty Harry film. This one's more exciting than scary, as the police hunt down this maniac. He's one of the cooler villains in film history though, because unlike the traditional drag-ass killer, this guy never speaks and just RUNS at you with a machete. He really SPRINTS at top speed, which is actually very scary, especially to a jaded horror buff used to the Michael Myers/Jason/zombie method of ambling on over to their victims, who usually have to trip in order to be caught. And there's one scene involving a light switch that will make you jump out of your undies. Stelvio Cipriani's score is again top-notch (he later reused part of it for Tentacles), the dubbing tolerable.
