This is a film I probably wouldn't try to review if someone more fluent than me in Italian (and that would include a WHOLE LOT of people) had already done so. This movie, unlike some dumb slapstick Italian sex comedy, has a lot of dialogue and fairly intricate plot that is hard to follow if you don't understand Italian very well.
The movie seems to be about a nymphomaniac (Lisa Gastoni), who has become a respectable married woman, but continues to have lots of humiliating sexual encounters with any number of unattractive (and in some cases pretty elderly) men, much to the consternation of her professor husband (Corrado Pani). She has public sex in a bell-tower while a parade is going on in the town below. She gets gang-banged in a night café in a visually memorable scene lit my neon lights flashing red and blue. And when she sees a creep sneaking the room of her nubile maid(at least, I think it's her maid)in order to feel up the nude body of slumbering young girl, she comes to the rescue--by having sex with the guy! She also has lots of flashbacks of her prostitute mother, and I suspect at least some of the sex sequences might actually be fantasies, like the opening scene where she is gang-raped, apparently by what looks to be some kind of androgynous zombiesque motorcycle gang.
This movie has some elements of a giallo (like the title and the visual style), a horror movie (like the opening sequence), and social drama, which is what Lisa Gastoni really specialized in the 70's. The scene with the young maid(?), for instance, resembles a famous scene from Fernando DiLeo's "The Seduction" where the Gastoni character's boyfriend sneaks into the room of her adolescent daughter to check her out while she sleeps. But this sequence here manages to be even MORE kinky. Director Giulio Perio is mostly know for spaghetti Westerns like "Death Rides a Horse". He is not as talented as some other Gastoni collaborators like DiLeo or Salvatore Samperi ("Scandalo"). Still, I would like to see a better-looking version of this movie (with English subtitles) before passing too much judgment on it.
