The title of this film is one of the most ludicrously lurid in the whole Giallo sub-genre, and that gives the viewer the right impression of this film. Some Giallo's strive for artistic merit, while others are more than happy to depict graphic, violent murders and make the sleaze and trashiness the main ingredient; this film is one of the latter. The film gets off to a very promising start, with a bloody murder that sees a young woman have acid thrown in her face before having her throat sliced open with a razorblade. While this sequence is poorly brought to the screen and suffers from really bad special effects, it's at least entertaining. However, from there the film quickly moves downhill, and director Riccardo Freda bombards the viewer with tedious sequence after tedious sequence, until the ending in which the film gets back on track. The plot after the initial murder sees the mutilated corpse turn up in the boot of the Swiss Ambassador's car. The Ambassador refuses to cooperate with the police as the girl was a former lover of his, and hard-bitten ex-cop John Norton is soon drafted in as the murders continue...
If Riccardo Freda could have made the middle of the movie as trashy and violent as the beginning and end, this could have been a pristine slice of Giallo sleaze; but the fact that the plot gets far too convoluted means the film gets boring too quickly, and despite a couple of decent scenarios in the centre of the film, there really isn't much to remember it for. The best sequence in the movie sees a young woman being chased through the streets by the murderer. The scene setting is good as the smoke filled pathway looks absolutely gorgeous, and the total lunacy of the conclusion to the chase bodes well with the trash theme of the movie. The acting leaves a lot to be desired and the poorly dubbed voices don't help. Of course, this isn't an actor's film; but considering the talent involved, this part of the movie should have been better. The murder scenes feel a little too much like an excuse to show blood and guts, and the fact that they aren't very well realised helps to ensure this. The climax is good, however, and while the identity of the killer doesn't really matter after watching the ninety minute ordeal, the revelation scene is good trashy fun. There isn't a lot I can recommend this for other than the obvious cult value; but fans of lurid cinema may find something to like.
