Following her strange disappearance, a man begins looking into his girlfriends' strange arrival at a small town that eventually leads him to a remote house occupied by a series of bizarre figures with a deadly secret that eventually brings a killer to the house knocking them off one by one.
This was a maddeningly ineffective and problematic giallo. Among the few positive points with this one is the ability of the film to at least work in the traditional genre elements somewhat effectively enough throughout here. The series of stalking scenes here aren't that bad, with the opening attack of the victim by the side of the road or a woman getting stalked in her bedroom while being spied on undressing and taking care of herself before going to bed, offering up some rather intriguing elements familiar with the genre. Both offer up clunky if still somewhat extended chase scenes featuring the unsuspecting victims going about their lives before running into the madman and being knocked off in silly-yet-brutal fashion featuring a slew of suspenseful stalking tactics and some fine nudity in the process. Other scenes, like a garden-set stalking scene or the killer taking out a victim in gruesome fashion before leaving the bloodied body to drown in a bathtub, make for equally sleazy and graphic encounters that set the stage for the wild finale that bring about some inventive twists for its positive points. Beyond that, there's just not much to this one that works. The main factor to be had here is the interminably boring and dull setup that has almost nothing at all interesting happening for long stretches. The whole idea of the disappearance taking place nearby and him coming to her aide to try to find her is a decent enough hook, much like the later investigation that turns up the family living in the remote house where he starts looking into the truth but it has just nothing all that exciting happening during this time. Dealing with a skeevy gardener making uncomfortable eyes at the young daughter, a scientist trying to make do with his latest discovery while being confined to a wheelchair, and the multitude of side characters that populate the house should've been a recipe for something to happen as he makes his way through the family uncovering what happened. Instead, everything is just undeservedly bland or drags on interminably with the outright worst of it being a dinner sequence that offers up nothing of any interest about anyone and never seems to end even with the notion of them being spied on the whole time. The other factor to this one is the general air of cheapness over everything here. The villa where everything takes place could've had some atmosphere but it's way too bright and cheerful to be effective at generating an air of danger, the flimsy effects give themselves away at nearly every opportunity with the outright goofy manner of their execution trying to look intimidating, and the whole presentation of the fabled machine that gets involved here is a straight mystery as we get nothing about what it is or how it works. The concept of the machine is such that it stretches credibility with how it even manages to catch the killer in the first place, and trying to place the actual figure doing the crimes at the point they were committed is a stretch at best and a gaping plothole at worst as it involves time-travel to pull off. It all comes together into one of the more underwhelming and bottom-tier gialli in the period.
