This documentary depicts actual historic sex films that date back to the beginnings of motion pictures. The moral values and standards of that era was extraordinarily conservative and severely inhibited. These films were forbidden and kept "underground". They were considered extremely lewd and were distributed confidentially. Although the explicit sex acts seen on these DVD's are quite commonplace today the eroticism and lustfulness of these films are greatly enhanced by knowing just how extremely shocking and verboten they really were back-in-the-day!
