Following a brutal crime spree, a police detective investigating a strange killer targeting unfaithful wives and adulterous spouses finds that a potential witness may help solve the case and tries to protect her when the killer starts to torment her while continuing his spree. This was quite the fun if slightly problematic sleazy Giallo. One of the more impressive acts here is the fact that there's a decent investigation wrapped around the strong sleazy thrills. With the introduction of the photography storyline in the crimes and using that as the main basis for catching the culprit, this one offers up the kind of traditional Giallo trope needed to drive the storyline forward with some extra notes that lead rather nicely based on the confines of the action here especially once it starts to signify the killers' chosen targets as that is a nice difference from most others who go for random victims at the start before the spree is found out. This addition makes for some fun as it builds that up into the remaining segments that play off this section of the storyline. Those stalking scenes are really fun, from the first encounter chasing the victim onto the beach from her apartment, appearing in the bedroom of the victim and chasing her into the bathroom for the final murder or to the tense sequence of the wife getting ambushed inside the backyard and ending up having the whole affair witnessed secretly by the daughter which is a rather enjoyable highlight offering. A dispatch on a train speeding through the night is incredibly fun as well with the darkened compartment hiding the killer rather well, and a later scene featuring the killer striking a victim in a bathtub only to then have the husband arrive and alter his exit strategy makes for a thoroughly enjoyable and tense sequence. As these scenarios allow for a constant stream of nudity and softcore fondling in showcasing their carnal exploits before the nude bodies are shown to be hacked to pieces, it gives this a rather fine sleazy air which all make for a rather fun genre effort. There are a few problems with this one, though, in that the film mainly employs a rather distressing hypocritical air that doesn't come off that appealing. Going off on the idea that the victims are being punished for straying from their husbands, a double-standard emerges when the male characters are also shown to be doing the same thing yet they never run into any kind of retribution because of it. Depicting them as heartless and needing to pay for their actions yet allowing the men to be okay with it gives it quite an old-fashioned air and tone that openly condemns their actions even though all the extramarital affairs are given loving, leering close-ups to see their full-on nudity. It's not a very welcoming tone for a horror effort and takes a lot of air out of the film as well as the fact that there's quite a long time in between many of these deaths as the investigation takes over to the point of ignoring a lot of other aspects here that don't make for an enjoyable time here. These hold it back even though it does have some worthwhile points. Rated X: Continuous Full Nudity, strong sex scenes, Graphic Violence and Language.
