Carter comes to. Trapped at the bottom of a ten-foot-deep pit, he begins to dig hand- and foot-holds into the soft clay walls. His work is interrupted by the three cavemen. Their spear-carrying leader leaps on Carter like a wild animal. In the ensuing brawl, the astronaut is beaten senseless. As the caveman raises his spear to finish him off, he is startled by the buzzing ring-tone of Carter's commlock. Fumbling with the device, the spear-man is intrigued by Sandra's image on the tiny TV monitor. Getting no response, she stops calling—her sudden 'absence' angering the spear-man. Using a tree trunk lowered by his comrades, he clambers out of the pit and shambles off toward the Eagles.
