A sympathetic anthropologist uses drugs and surgery to try to communicate with a primitive troglodyte who is found living in a local cave.
Anthropologist Dr. Brockton (Joan Crawford) unearths a troglodyte (an Ice Age ‘missing link” half-caveman, half-ape) and manages to domesticate him – until he’s let loose by an irate land developer, and goes on a rampage, terrorizing the local citizenry.
