This untranslated Italian import is a staging of the making of an adult film.  Camera, crew, and director are all on hand to instruct performers on what goes where and at what angle.  Included in the action are couples, an outdoor girl/girl (one has huge natural tits), a d.p. and a four person stairway fling (with a touch of anal).  You may have the urge to stock Impulse 2: The Movie.
