from the director of the excellent what have you do to solange and massimo dallamano and here be a strange italian giallo and more a police procedural ( an a really lurid tale and a ring of teen use a prostitute by people in very high place that be the time and in italy and when several director and scripwriters try their hand on very hot subject and like this one ) than an argentian thriller ( but it be scary enough in a few place and also very gory ) . it start with the false suicide of a very young girl and hang nude under a roof and then proceeds with a lot of car and bike chase ( the killer be always cover by a motorcycle helmet until the very end it be possible that the director of night school take from here the idea of the killer mask with an helmet ) and almost always run without pause . tense and scary enough and good almost till the end ( a lot too dillenger for my taste ) .
