With the competition in its final stage, only one survivalist's resolve can secure them the $500,000 prize. As the temperature dips well below freezing, the river stops paying dividends. The three participants are forced to weigh tapping out versus a lifetime of regret.
Alone puts survivalists by themselves in the wilderness, without camera crews, support teams, or producers - on a single mission to stay alive for as long as possible. The last person standing will win $500,000.
