On Moonbase, Bergman attempts to call Koenig, but gets no response. Carter reports that he, too, is unable to contact the Commander. At their geographic latitude, the night will last only two hours; Carter decides to land and commence searching for the others at daybreak. Sandra claims to see something moving in the fading light, but Carter cannot confirm her sighting. He brings the ship down next to Eagle One. As Carter and Sandra settle in for the night, a trio of cavemen watches the ship from the bushes outside.
