Synopsis: The apparent suicide of a teenager girl turns out to be murder, and the police continuously fails in finding the leather-clothed killer riding a motorbike.
Review: The topics of teenage girls and their troubled lives seems dear to Dallamano, as they are already tackled in his movie of 1970 What have you done to Solange? which is very similar to this one. A difference is that here the killer has a distinctive look (leather, motorbike, helmet, preferred weapon) which brings the movie closer to being a Giallo like Dario Argento was doing them. There is no restrain in the description of the habits of the teenagers, which makes the movie sometimes quite brutal. The way the police investigation is done and the conclusions they draw are sometimes ridiculous, but on the other hand the apparitions of the killer are full of tension, and the 15-minute chase car vs. motorbike after one hour of movie is very well done (except for the continuous siren sound which is annoying). The independant editor of this DVD edition The Ecstasy of Film made quite a good job: film transfer, new cover, booklet, rare interviews. But the image compression is sometime pretty bad, defects of the film visible (vertical stripes), and the sound is too weak and muffled. A Blu-ray edition would have been welcome for this classic Giallo.
