On an uninhabited, frozen planet, Stella and Elle investigate the mothership crash site. As with the first crash site, they find no survivors. Upon their return to the ship, Thor, who has ambushed and apparently knocked out Akton, reveals that he is an agent of Zarth Arn. Thor locks Stella and Elle outside on the planet's surface, where the temperature drops thousands of degrees at night, but Elle is able to preserve Stella's life by using his energy to keep her heart going while they freeze over in the snow. Meanwhile, Akton revives and battles Thor, killing him and subsequently rescuing Elle and Stella.
