Winter descends upon the survivalists, forcing them to adapt to the drop in temperatures. With the snow comes a rush of emotion and the participants are tested in their resolve to keep working towards the $500,000 prize. One survivalist settles in for the dark days ahead, while another makes a surprising discovery.

The three remaining survivalists brace themselves for the fight to the finish. One participant finds it impossible to stay warm, while others risk it all on the ice. Though they all push themselves to their limits, only one can claim the $500,000 prize.
