Told by way of a retrospective, this is quite a fun story of prehistoric man and for once, Victor Mature is pretty much in his element. He plays "Tumak" who is exiled by his "Rock" tribe and takes refuge with the far more refined "Shell" people where he settles down and marries "Loana" (Carole Landis). Unfortunately for him, he manages to get exiled from there too - so returns to his old tribe, with his new wife, and tries to pacify them and their nasty leader Lon Chaney Jr - all under the menacing threat of an active volcano. It has precious little dialogue for the star to chew his way…
