In this survival scenario, hosts Cody and Dave find themselves on a deserted island off the coast of Nova Scotia — in the dead of winter with plummeting temperatures. Despite the freezing temperatures — and his partner's objections — Cody doesn't give in on his indigenous survival strategy, where he lives his life barefoot. Here, he's only wearing shorts and wool socks. The only items they have are those they're able to salvage from the life raft they used to reach the island: an emergency Mylar blanket, a plastic tarp, two knives and a single rescue flare. They must use these items and their arsenal of skills to find shelter, build a fire and find food and water, all in sub-zero conditions.

Next, our survival experts take on a mountaineer's worst nightmare. They are left stranded on top of a mountain in New Zealand with limited supplies that would be carried by a climber: rope, crampons, an ice axe and other climbing gear. Working together, they battle 8,000-foot glacial peaks, deadly crevasses and deep rocky canyons as they trek down the mountain on a course set by Canterbury, an experienced climber. To find food, Lundin uses his knowledge of local cultures to tap the dietary wisdom of New Zealand's indigenous Maori.

Each year, an average of 20 people drown while cave diving. For this survival scenario, survival experts Cody and Dave are lost divers who are fortunate to find air, but they are deep inside a maze of caves in Belize. Equipped with only their dive gear — mask, fins, wetsuit, buoyancy compensator and flashlights — they must find their way out and to safety. The survival rules that work above ground, like following a river downstream, don't apply in the labyrinth of underground caves. Instead, they must make their way upstream in a trek that puts Cody's barefoot philosophy to the ultimate test. Once they emerge, the situation goes from bad to worse — they find themselves surrounded by dense jungle, a web of vines and thorn ravaged terrain... and snakes.
