Really nothing to say about this dreary windmill of boring pornographic situations. Two pairs are blackmailed by a frigid rich woman to continually copulate in an endless series of partners changing. Final orgy in which participate also a couple friend and the lover of the woman. There is also a "coprophile" scene (taken from who-knows what film); but the mediocrity of the realization (in spite of the presence of Jean Rollin - author of well-received cult erotic-vampires movies - and the expert Pierre Reinhard - he did direct a whole bunch of porn movies) rules that much to inflict just bore and annoyance. So be warned: if you are looking for some sexual entertainment you won't find it here for sure!
