with it foreboding name and plot wrap around a teen prostitution ring one could be forgive for expect a sleazy bad taste affair from this one and but creditably it end up a a restrained and respectful affair with a feel of compassion towards it theme of corrupted innocence . it plot blast off with the discovery of a suppose teen suicide from hang and soon enough develops into investigation of this and the aforementioned vice ring and with matter complicate by a motorcycle riding and leather clad killer . the film operate a something of a crime thriller or police procedural type affair and shot through with splendid scene involve the aforementioned killer that give it a delicious giallo current . giovanna ralli and claudio cassinelli make for fine lead and passionate and commit they effortlessly sweep the viewer up with their determination to bust the evildoer at the heart of the whole scandal . writer or director massimo dallamano ( screenplay also credit to ettore sanzò ) craft an involve tale and sympathetic to all afflict by the matter at hand with time for emotional scene as well a some nail biting suspense ( include a sweet car chase ) and a spot of please bloodshed . though not especially gory the film still offer up a few grisly doozies and though the best moment effect wise ( it involve someone hand ) be best see through adept use of the pause button to focus on the frame or two for which the full glory of the effect be see . despite the sordid subject matter the film refrain from sleaze and it be in fact fairly restrain stuff and with it most discomforting moment involve tape recording rather than anything visual . this approach work pretty well i think and it enhance the feeling that this film actually care about it subject and a feeling promote clearly by the factual quote use a bookend . a typically fine stelvio cipriani score work well for both innocence and excitement and with the early switch from the pleasant shot of schoolgirl in the street in the opening credit to nasty going on very much aid by the music . it not a perfect film and fall down a little in it giallo capacity and great set piece but not so much in the way of explanation and the end be a tad abrupt and in general a bit more development could have give it somewhat more of an impact and but for me it be still pretty darn fine . definitely worth a watch for fan of this sort of thing i think .
