I sometimes have a hard time explaining to people why I love old style "sexploitation" movies, but hate porno movies. It's really very simple though: while porno movies are wall-to-wall sex with pretty much nothing else of interest in between, "sexploitation" movies were more limited in their sexual content due to censorship and/or the audience tastes of the day and so had to come up with something else to fill in their running time--and the best of them actually took advantage of their "captive audience" of lonely men in raincoats to do things even much bigger-budgeted mainstream movies would never dare try. Of course, this movie does not compare with the best of the genre (i.e. the works Jean Rollin, Jose Larraz, and Alain Robbe-Grillet in Europe; or Joe Sarno and Russ Meyer in America), but it is solidly entertaining.
This movie focuses on a small German town full of old men with young, sexy wives that seems to owe its unusually high birthrate to the "foehn", a wind that blows periodically and supposedly confers virility on the males who breathe it. But what is actually responsible for the fertility phenomenon is the studly young blacksmith who takes advantage of the fact that the town men are all out taking their constitutional in the "foehn" in order to get together with all of their luscious wives. The problem comes when a young, virginal daughter returns to the village (from school, I guess) because virgins and the "foehn" don't mix (and she by herself turns out to be more than the young blacksmith can handle). Thrown into the mix are two visiting nude artist models, a childless couple hoping for some of the "foehn's" magic, and a "population" bureaucrat and his sexy micro-mini-skirted secretary.
This movie isn't outrageously funny, but I found it interestingly exotic with its references to German folklore. I saw it as part of a collection of "Bavarian sex comedies" and it was really the only one of the bunch that seemed distinctly German. And the girls are all very pretty and clearly all-natural when presented in the au natural (which they frequently are). Of course, if you prefer modern-day shot-on-video porno flicks with tattooed skanks who are more silicone than woman having hardcore sex in someone's townhouse in the San Fernando Valley, you probably won't care for something like this, but I enjoyed it.
