This is the story of a teenage girl who runs away from her adopted family for vague reasons (her adopted brother is cruel to her, she is taken advantage of sexually by the boys in school). She "turns the tables" on everybody by going to work at a brothel, then striking out on her own as an internet call girl, then starting a pseudo-feminist blog as "Bruna Surfergirl" where she "rates" the performance of her male clients (which you would think would be bad for business), and somehow becoming the most famous hooker in Brazil.
This movie is based a real-life story, but it is of a piece with a lot foreign movies I've seen lately from France ("Student Services", "Elles", "Young and Beautiful"), Eastern Europe ("A Call Girl"), and Chile ("Joven y Alocado"). This is less preachy and socially alarmist than some of the others, but I think, like them, it definitely glamorizes prostitution quite a bit, both for women (this really doesn't seem like that bad of profession) and definitely for men since all these actresses are insanely hot and much more wholesome looking and genuinely pretty than any actual streetwalker who services thirty men a week and abuses hard drugs would ever possibly be. You could complain that the actress, Deborah Secco, was nearly 30 here and playing an 18 year old, but she probably LOOKS more fresh and innocent than any real teenager who has spent six months working the streets. Prostitution is obviously enticing sometimes to both female providers and male clients, but at best it's like a tasty-looking meal that happens to be lying in a garbage dumpster. These movies kind of tend to ignore the garbage dumpster.
If you're just looking a hot sex movie with higher production values, better acting, and more of a story than "Cinemax After Dark", this movie is definitely worth watching, but don't expect any profound statement on the human condition.
