After radioing their base camp, they attempt to walk the 900 miles back to it, dragging Rondelle on a sled. Rondelle soon dies and is buried. Later, Frisky has to amputate Sock's foot. When Sock realizes he is too much of a burden, he drags himself away to die while the other two are sleeping. They carry on, but Hansen breaks down when he finds they have been going in a circle and have returned to Rondelle's grave. Frisky refuses to give up and forces Hansen to continue on.
