I saw the last few minutes of this film years ago and do not know what it was. The ending involved people in the woods (mountains?) where some very tall mutant guy threw 1 or more over the edge. Then he kidnaps the last surviving girl and takes her back to a cave. The closing scene is of the cave with the sound of a baby coming from it. So apparently he started his family with her. B-movie quality from what seemed like the 80's or possibly '70s.
