a young naked schoolgirl be find hang in a room lock from the inside and the police suspect suicide and until that be the clue seem to point in the direction of murder . so when the police lead by inspector silvestri ( claudio cassinelli ) with the assistance of the asst district attorney vittoria stori ( giovanna ralli ) realise that they be investigate a teen prostitute ring with some highly influential people involve and they know they be go to have a tough time convict anyone and sure enough their investigation be dog with interference and dead end . dallamano director of what have they do to solange . again return to his schoolgirl in peril theme story and like it predecessor it a highly controversial topic that be handle professionally and intelligently . despite it topic and there very little in the way of visual sleaziness here and the offence against the girl be confine to tape recordings the police have and it from these that they build their case . the film be in fact only half giallo and play more like a poliziotteschi ( italian police procedure film ) and we only get brief glimpse of the leather clad killer a he try to cover up his identity by kill those who might be able to give him away . stelvio cipriani again provide an excellent score and the film look good visually and no more than you would expect from a director who use to ply his trade a a cinematographer and there also a very memorable chase scene that liven up the film immensely . claudio cassinelli and cortese provide some fine acting in their respective role and if there be such thing a a high brow giallo this must surely be it .
