In ONE MILLION BC (1940) Victor Mature plays a rough cave man named Tumak who is banished from his tribe and cast, unconscious, into a river. Carole Landis plays Loana, a beautiful cave girl from the more civilized Shell people, who discovers him and falls in love. Tumak is banished once again–only this time Loana, is willingly at his side. Together they survive a number of deadly prehistoric animals–on their quest to find Tumak’s home.
