On a class excursion to a cave with stone age paintings the clumsy Rex gets lost. A mysterious crystal opens a gateway in time and sets him back to the stone ages, where he meets a group of prehistoric fellows and the gorgeous Eba. While teaching her English and doing some pseudo-research on her fellows, his main goal is to get her sleeping with him. However the curiosity of the clan chief disturbs his attempts.

Writer, director Daniel Roebuck and long time collaborator, David Hansen Sturm, team up on this one of a kind MAKING OF documentary celebrating Roebuck's first and almost certainly worst feature film. Many teenage sex comedies were made in the 1980's and have long disappeared from the public consciousness (mostly for the betterment of mankind) yet CAVEGIRL is released constantly on DVD and remains a fan favorite. CAVEGIRL, A SECOND JOURNEY back in time is a unique and fascinating look into the creative process of this late night staple.
