Not that it matters, but the "plot" is about two "schoolgirls/ high school" girls (who look like they're in their early 20s) out hiking in the woods and stumble onto a once lavishly furnished but now seemingly abandoned house and make themselves at home. Their little night of lesbian fun is interrupted by a balding, stick-skinny guy who, after they have a three-way with him, turns out to be involved with jewel smugglers. The two girls are then suspected of taking their loot, and are then (mildly) tortured to get them back. There's also a voice-over narrative, as though the lead girl was recounting the story to the audience at a later time, but, why?
Let's be honest here: nobody is going to watch a movie with a title like "High School Hitchikers/ Schoolgirl Hitchhikers/ Jeunes filles impudiques (Impudic Young Girls)" because of its plot, acting, photography, or elaborate effects. People are going to watch this film to see a bit of nudity, and maybe have a few laughs at the film's expense. On that level, the film works fairly well. The girls are cute and nude often enough, and none of the violence is overpowering, so it never goes off into torture-flick territory. A few laughs can be had with this one, if watched in the right frame of mind.
