This is a German "sex-report" film about lonely housewives that is similar to, but apparently not an official entry, into the long-running "Hausenfrau-report" series. An oft-naked male reporter decides to do an expose on "sexual widows", housewives who are neglected by their busy husbands, after his interest is piqued by his attractive neighbor quarreling with her husband (and then wandering around naked for some reason). The women he "interviews" are an unlikely lot to be neglected wives as they are all very attractive. And his "expose" is pretty half-assed frankly (but it does allow for seeing a whole lot of people's entire asses).
As in other "report"-style films, this is broken up into various stories. The first story with the neighbor is quite conventional (the reporter bangs the housewife), but they do get a lot more interesting--or, at least, a lot more demented. One older woman entertains herself by playing nude badminton(?) with a female friend while her husband is at work and her teen daughter is at school (then the pool cleaner comes by...) Another woman catches her husband with the female half of another couple, which (naturally) turns into a four-way "group marriage", bi-lesbian thing. Another woman nude-models for a class on how lonely wives can sexually fulfill themselves (guess how). A husband starts an affair with his mother-in-law while his prostitute wife is off-turning tricks (I'm not sure who the "lonely wife" is here). A woman cheats on her attractive butcher husband with an overweight pervert, leading to an interesting montage sequence inter-cutting a scene of her being tied up and whipped by her lover with a scene of her oblivious husband butchering a cow carcass (which perhaps says something about the filmmakers' attitude towards women). Perhaps the most politically incorrect story though actually ends with a tragic death(!), which leads the reporter/narrator to muse whether it was the fault of the female victim, her neglectful husband, or the creep who tried to rape her (um, I'm pretty sure it was the creep...)
