This is a movie about a teenage love triangle with two boys and a girl. One of the boys is from a relatively wealthy family, while the other, the main protagonist, is from a troubled family with an alcoholic cabdriver father, who are so poor they have to periodically turn off the power, which is why he has to take cold showers (although that may not be why some members of the audience will have to take cold showers). The plot of this movie sounds like a John Hughes flick, but this is a FRENCH movie and has something John Hughes movies definitely DON'T have, I think it's pronounced "menage a trois". If only the characters in "Pretty Pink" (or more recently, the vampire, the werewolf and Kristen Stewart in the "Twilight" saga) had thought of this, we could have been spared a lot of needless teen angst.
Interestingly, the first menage a trois occurs BEFORE the love triangle emerges when the poor kid spontaneously decides to share his sexy girlfriend with his wealthier buddy after a co-ed wresting practice goes very awry. The movies never quite delves into full-blown bisexuality, and I don't know why because there is certainly no shortage of blatant homoeroticism. The two males both love wrestling, taking showers, and occasionally wrestling in the shower. The girl (Salome Stevenin, who could probably turn gay men straight) actually has fewer full-frontal nude scenes than the two males, but one of them is another scene you're probably never going to see in an American teen flick where she wipes down her upper thighs after having (apparently) unprotected sex with both guys.
I should add that nobody here looks anything like an actual teenager. All three leads are obviously very good-looking twenty-somethings (even the French don't use actual underage actors in movies this graphic). And while they're less sexually repressed in France, I don't think it's common for French teenagers to have three ways in school gyms and showers. Ironically though considering how graphic this is in parts, the teens here seem a lot less sexually obsessed than American teens in movies, who always seem to be single-minded virgins trying to "lose it" as if it were the quest for the Holy Grail as opposed to something that inevitably happens to pretty much everyone with functioning genitals. Few people realize that this whole "horny male virgin" plot in American movies was borrowed wholesale in the early 80's from the Israeli "Lemon Popsicle" series, which was set in the FIFTIES for christsake. The French aren't stuck in this time warp and they treat teen sex much more matter-of-factly with slightly more realistic teen characters who occasionally think of something else besides just getting their naughty bits wet.
Even as a teen, I only watched stupid teen movies for the gratuitous nudity by the attractive 25-year-old "teen" actresses. But even that went away in the benighted John Hughes era, and strangely "American Pie" brought back the raunch and ridiculously sex-obsessed teen virgin stereotypes, but it didn't really bring back the gratuitous nudity/sex. Ironically, American teen movies today not only probably send a bad message to teenagers about sex, but bore the hell out of any adults expecting to see any. By that standard this French film with its unveiled homoeroticism and rather graphic sex scenes is really quite an improvement.
