12 elite survivalists take on the sub-freezing Rocky Mountains of Montana.

A newly-formed tribe quickly works together to stalk and kill a caiman; the pressure to trek forty miles to extraction pushes two teams to make risky migrations; a survivalist is on the brink when medics discover parasites in their digestive system.

A massive food win buoys Terra and their whole team. Malorie stalks a bigger prize. Heather is shocked to learn Adam has not been sharing food.

Far from extraction, Kaiela leads her team on a punishing trek that puts her challenge at risk. Adam and Heather's smoldering tension makes the new camp choose sides. Desperate for protein, a risky survival choice pushes Heather to her breaking point.

An overnight snowstorm tests the survivalists' will; pushing through foot injuries, Jake scavenges a challenge-changing food win; with Jeremy struggling, Trish needs to step up; heart conditions put Sarah and Joe's challenges at risk.

Ahead of extraction, a hunt gone awry leads to an all-out jungle search.
