Alone

With only four people remaining, food insecurity reaches an all-time high. One participant's prized harvest is pilfered, while another survivalist battles a debilitating sickness brought on by an unfortunate source.

As the river finally begins to freeze, the remaining survivalists struggle with the loss of daylight. One participant's snare line gets stalked by a vicious predator, while another devises a plan to defeat a longstanding enemy.

The Arctic's frozen landscape continues to push the remaining survivalists to the brink. One participant finds themselves at-risk for frostbite, while another is convinced the end days are near.

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.
