This is one of the first films of Gloria Guida. I can't say I really followed the plot because the version I saw was dubbed into German with no subtitles in English (or Italian or Spanish or French). What I got out of it though was the Guida is playing her usual high school girl in trouble, but this isn't one of the typical low-brow, idiotic "Liceale" sex comedies she'd later be famous for--this is more of low-grade drama similar to "Blue Jeans", the other film she later did with the same director (Mario Imperioli). "Monika", Guida's characters in this film, is dealing with three male suitors: One is a creepy peer (played by the same scrawny actor from "Blue Jeans") who is pimping out her female classmates to older men. The second is a middle-age lech, and a client of the teenage pimp, who becomes obsessed with her. The third is a swarthy, slightly older lothario who is also carrying on with the middle-aged guy's frosty wife. "Monika" also has some kind of relationship with the wife (Colette Descombes from the Carrol Baker/Umberto Lenzo giallo "Orgasmo"), at least enough to merit them taking a topless swim together.
I couldn't spoil the plot if I wanted to, but suffice it to say that Guida gets naked a lot, loses her virginity to one of the guys, and someone dies at the end. Perhaps the most memorable scene takes place at (her birthday?)party where "Monika" is wildly dancing in a mini-skirt surrounded by a group of guys. The lights suddenly go out, her panties somehow end up on the dance floor (where they're surreptitiously scooped by the middle-aged lech), and the audience is treated to a LONG low-angle shot of her "pants off/dance off". Like the whole movie though the tone of this is a strange mixture of comedy and drama--"Monika" seems a little traumatized by this development, but certainly not traumatized enough to stop dancing.
Anyway, if you've never seen Gloria Guida in action, she was one of the most ubiquitous of an incredible crop of Italian actresses who came of age in the 1970's Golden Era of Italian exploitation film (including Ornella Muti, Jenny Tamburi, Eleanora Giorgi, Lili Karati and dozens of others who would never get kicked out of bed for eating soda crackers). She kind of resembled a young Brigitte Bardot or Barbara Bouchet. And I don't think she ever met a film role she wasn't willing to take all her clothes off for. This is not a very good movie (and it might not be much better, and could even be worse, with subtitles), but god knows I've suffered through much worse movies for the sake of taking another gander at the gorgeous GG.
