Synopsis:
This outrageous comedy follows the exploits of the hapless ishbo (Adam Rifkin), a philosophical caveman who yearns for more out of life than sticks, stones and raw meat. Determined to single-handedly advance the human race, Ishbo continually irritates his fellow Neanderthals with ridiculous inventions like the ladder, the sun visor and pants. His exasperated parents (David Carradine and Talia Shire) wish he would be more like his dimwitted brother (Hayes MacArthur), who has the strength of ten mastodons and has clubbed every girl in the tribe- including Ishbo's dream girl, Fardart (Ali Larter). Can Ishbo pull his species out of the primordial doldrums?
