A tribe of women in a prehistoric age turn aggressive to capture and enslave their future husbands, but the tables are turned when one of the men discovers fire. 

Despite the no-name cast and meager production values, this production was surprisingly filmed in color, although it's difficult to make out much in the poorly lit night scenes (unless that's the fault of the public domain print I viewed).  There was enough going on plot-wise to engage me, and the ever-present narration of David Vaile was appreciated in the light of the made-up language of the tribes.  The gender role reversal in the first half of the film, especially for the time, was refreshingly progressive, although it of course doesn't take it far enough by the climax.  The filmmakers also made some attempts to add intrigue with some savage animals including a manufactured winged beast, as well as a giant caveman.  It's still not that good a movie, but I found it watchable enough.
