About the search for an adult who pushed a classroom full of troubled teens to gang-rape and murder their female teacher. A hard-bitten Police Inspector named Liberti is put on the case and sets about brutally...
Weak & Bland. Except the rape scene which was good enough to be showed both as the intro and at the conclusion, with some really edgy proto-noise music (remember, this is 69'!), all the rest is either okey-ish (e.g. main actor) or plainly bad (e.g. useless female chara & plot)
not so much as a giallo (or even a proto-giallo), but a social problem film。realistic, hard-edged style
