Twelve elite survivalists take on their toughest location yet, Montana's sub-freezing Rocky Mountains.

For the first time, twelve 21-day survivalists take on the Colombian Badlands for 40 days and discover that they must travel 40 miles to reach the end. Extreme heat, rain, bugs and deadly cats tests their endurance like never before.

With day 60 extraction looming, a hunt goes awry and leads to an all-out search for wounded prey. The team's raft build could be a crushing waste of time.

Desperate to get food, EJ creates poison blow darts to chase a much-needed meal. Matt spearheads an ambitious dock build that drains Dan's strength.

The final six survivalists come together as one group but must scramble to expand their shelter. The Amazon unleashes a bee swarm and a torrential storm.

Amber joins forces with Steven and EJ, but a distant fishing hole means a punishing journey for their next meal. Dan and Waz make a high-risk choice.
