The Mountains of North America haunt the imagination, masking a danger few are willing to confront. Despite the challenges, some choose to live this way, the last of their kind. Eustace Conway lives deep in the mountains of North Carolina. He moved here 33 years ago in search of a more "truthful" existence. In the years since, he's built a home, and survived by hunting, fishing and raising animals. Tom Oar lives with his wife on the Yaak River in Montana. He is 100 miles from the nearest town, a place he hasn't ventured to in 10 years. Marty Meierotto, his wife Dominique and their daughter Noah live in the small Alaskan town of Two Rivers. Every month, Marty pilots his bi-plane, traveling into the bush in search of the wolverine and lynx pelts he needs to make a living. While he's on the Black River, he must hunt moose and caribou to survive in the wilderness. Together, these men represent America's true Mountain Men.

Eustace's fight with Justin reaches a boiling point while Tom loses his way high in the Rockies and Marty fights the elements as he tries to get home.
