Prehistoric tribes on the loose grunting their way across Africa, facing mini-cataclysm and indulging in non-stop savagery. In a "2001"-ish Dawn of Man mode, their customs are delineated well, although their beliefs in the supernatural and their origins are handled crudely. The big difference: no oversize creatures appear in this one other than a big grizzly bear.
