Old school giallo with a much different premise, told mainly in flashback, so although there's a lack of gore, things still feel pretty refreshing.
What you have here is the story of Alexa, a young Rosalba Neri who has married an old Curt Jurgens, much to the annoyance of her fellow student Emma Cohen, mainly because Curt is her dad. We find out right away that Rosalba is having an affair with hunky Pietro, and both of them aren't so discreet about what they are up to (check them out on the beach at the start of the film. Rosalba's standing there in the buff when there's clearly passers-by getting on about their business. Intentionally left in? Who knows.)
At the same time we see this, we were also shown that Rosalba's husband is up to something at their little love nest, checking doors, windows and such like, so we get the drop that he knows about the affair and is planning on doing something too. What it is though I'm not revealing, as it puts a nice twist on the tired genre and sets up the story for flashback city, and of course further twist.
Usually these films have people scheming against each other and everything comes to a head, but by playing these cards early you do get caught up in the story and wonder what's going to become of the main characters. As usual, Rosalba Neri, although frequently shedding clothes, is also a good actress, so you get to feel her pain. On the other hand, Emma Cohen gets underused as Curt Jurgen's daughter.
A good film about bad decisions and regrets. And greed.
