When a Paleolithic case of global warming threatens to end the Ice Age, ne’er-do-well caveman Kyle must figure out a way to stop the melting and save his village. Unfortunately, his idea of a free-love utopia does not sit well with the villagers, particularly the caveman of his dreams, Steve. With a highly revisionist take on the oft-maligned Neanderthals, this prehistoric comedy is a very possible, highly improbable exploration of the first instances of caveman quarter-life angst, caveman sexual frustration, and of course, the invention of the wheel.
