Cavegirl

On a field trip to a cave, nerdy teen Rex (Daniel Roebuck) is separated from his class and chances upon a magic crystal that transports him back to the Stone Age. There, he meets Eba (Cynthia Thompson), a cave girl who doesn't seem at all bothered by Rex's lack of social skills or style. Rex sets about teaching Eba and her people how to speak English -- and hopes to score while he's at it. But dating isn't easy in prehistoric times, either!
