Les Chevaliers de la Croupe (Knights of the Rump) is another forgotten French sex movie from the 70s. As was often the case at the time, it seems to exist in both a softcore and a hardcore version. This one if, of course, strictly softcore. Please note that the famous Claudine Beccarie, whose name is prominently featured on the poster, has only a small part.
The story : a French bourgeois family sees the commercial potential of pornographic movies and decides to produce one. Much hilarity and a lot of sexual shenanigans ensue.
