The biting Canadian winter closes in, bringing new challenges as food becomes increasingly scarce. Tom builds a makeshift mouse trap and finds a bonus source of calories–but suffers an injury that could threaten his chances in the competition. Meanwhile, Alan’s attempts to find a meal become increasingly desperate and Elise’s fishing efforts are sabotaged by a beaver. The mental challenge of surviving alone takes its toll, as Eva relives a heart-breaking time from her past and Louie’s loneliness reaches crisis point. As conditions get tougher, more people tap out of the competition. The finalists receive a surprising morale boost, but who will have what it takes to survive the longest and claim the 100,000 prize?
