This was made with scenes from Hôtel très spécial (1977), some new footage and footage from three American films, some of which was also used in Hôtel très spécial. No director is mentioned. In the (identical) 'Orgasmo bianco' and 'Voyeur' versions one of the inserted American solo scenes is absent.
The new footage features Brigitte Verbecq masturbating while watching a video of the Amber Hunt fisting scene from Candy Stripers. She is meant to be doing this in the apartment next door to that of Gilles Mouroux (aka Laurent Dubois?) who, in footage from Hôtel très spécial. uses a telescope to spy upon the sexual antics of some girls (including Danièle Troeger, Valérie Martin's) in a room across the street. Later he succeeds in getting to know them better.
