Finished by Joe D'Amato, from an unfinished Jesús Franco film shot in 1975, spliced up with footage from Franco's own Midnight Party (1976) and Shining Sex (1976).
Despite being first billed in the credits, Alice Arno does not even appear in this movie. This fake credit frequently leads to confusion between this film and Claude Pierson's non-porn Justine De Sade (1972), starring Arno, to which this film has no relation whatsoever, and is definitely not a hardcore re-edit of.
