Documentary-style, voice over narration is not the ideal format for a film, but on rare occasions it is the preferred one. Such is the case with Prehistoric Women (1950), which without the narration, would've been infinitely more annoying had they decided to use invented "cave man" dialogue throughout.
Tigri is the undeclared leader of a tribe of prehistoric women (who are all beautiful, with immaculately groomed hair, white teeth, and short-skirted, form-fitting animal skin attire).
For unimportant reasons, they have grown to despise and have contempt for all men. They spend their days lounging around looking sexy...
and spend their nights dancing around in bizarre rituals...
One day they come across a group of men in the jungle. The women easily outnumber, outmatch and overpower the men a take them as prisoners/slaves.
Despite their disdain for men, the ladies show a natural fondness and inclination toward the opposite sex and begin to partner up with their desired mates. This leads to an epic, prehistoric cat fight when two women claim the same man...
The men are still regarded as subservient, but this changes when it is revealed that one of the men has discovered fire. He uses the fire as a weapon to defend the ladies against a pterodactyl and the evil giant, who has been tormenting the cave people in the jungle for all of recent memory...
Can the cave women and cave men find and nurture a mutual respect for one another and thrive?
