Teenage Cave Man

A tribe of primitive hunters lives hemmed in by a forbidden zone, a stretch of land their elders say no one may cross. The Symbol Maker's Teenage Son (Robert Vaughn) wants to see what is out there, and Roger Corman sends him across it in a 1958 black-and-white picture made fast and cheap. The Blond Maiden (Darah Marshall) stays behind with the tribe while he goes, and nothing about the place is spelled out beyond the law against entering it.
