Cavegirl

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.

My take

A prehistoric comedy romp where a modern woman somehow ends up in caveman times, leading to fish-out-of-water hijinks and romance. It's got that campy '80s charm—silly, earnest, and not taking itself seriously for a second.
