A prescient film which, in 1976, deals three themes so new and with a promising future in the world of hard hexagonal: Agency marriage at the edge of the computerized progress has become a foolproof "factory couples", swinging, and already running sodomy in the Nordic "loops" of the time (cf. Lasse Braun) but still little common with us. A film rare for savvy X moviegoers who not only wants to be the champion of the "narrow gate" but still brings his touchstone for the democratization of a new sexual imagery.
