You’ll be shocked, amazed, and maybe just a little bit creeped out by the things you can find in your newspaper’s classified ads in this vintage sexploitation “mockumentary” from Joel M. Reed. Georgina Spelvin serves as host and guide to this exploration of the sexual netherworld, which can be accessed through discreet ads placed in “underground” newspapers and on public bulletin boards. We meet voyeurs looking for good peeping spots, homosexuals on the cruise for new partners, masked swingers clubs, nudie photographers trolling for naïve new models, a man who makes a good living providing S & M enthusiasts with leather gear, adult film societies screening stag movies for heavy-breathing fans, and “Lonely Hearts Clubs” preying on unsuspecting bachelors looking for relationships with teenage girls. Director Joel M. Reed (who would later make the bizarre horror-comedy Bloodsucking Freaks) and actress Jennifer Welles (a major star in 1970s adult films) can be spotted in cameo roles.

Tracing the history of adult films, from ‘Deep Throat’ and ‘Devil in Miss Jones’ to the high-definition, big budget movies of today, this documentary chronicles the most important, critically acclaimed and sexiest movies in history. Features clips from the 32 greatest adult movies ever produced and in-depth interviews with the biggest stars in adult film history, like Jenna Jameson, Ron Jeremy, Marilyn Chambers, Christy Canyon, Jessica Drake, Georgina Spelvin, Allie Haze, Andrew Blake, Stoya, Constance Money and Kay Parker.
