A philosophical caveman discovers that there's more to life than sticks, stones, and brontosaurus burgers in this prehistoric comedy from cult director Adam Rifkin (The Dark Backward). Ishbo (Rifkin) isn't your average hunter/gatherer; in a world dominated by Neanderthals, his fellow tribe members openly mock his sincere attempts to advance the human race. Convinced that cave-dwelling beauty Fardart (Ali Larter) would fall for him if he could only come up with something truly revolutionary, Ishbo invents such useful items as toothbrushes, ladders, spoons, and pants to no avail. When using his brain fails to help him win the girl, Ishbo considers resorting to the tried and true method of simply dragging her away by her hair, though his dim-witted brother Thudnik (Hayes MacArthur) beats him to the punch. Later, an enemy tribe launches a surprise attack from the other side of the hill, prompting Ishbo to fall back on his smarts in hopes of saving his people and impressing Fardart.
