Ten survivalists from previous seasons return for redemption and a second chance to win the 0,000 prize. But this time, they face the dangers of Northern Mongolia, a location more wild and more remote than they've ever seen.
Participants explore new - and risky - food sources in Mongolia. As the survivalists begin to settle into their new remote surroundings, they realize they're not the only predators on the prowl.
The survivalists begin to face external and internal threats as they work to secure food and complete their shelters. One participant comes face-to-face with one of Mongolia's deadliest predators, while another fights to overcome a debilitating health issue.
Mongolia shows how devastating its climate can be as a monstrous storm assails the remaining survivalists. The participants are forced into their shelters and can only hope they'll hold up to the fierce wind, rain and lightning.
Seven remaining survivalists are pushed to their limits as the weather worsens in Mongolia. One participant makes a bold gamble, turning to tree bark for sustenance, another questions his ability to continue killing for food, and one faces a dangerous predator lurking in the darkness.
After almost a month of solitude, the remaining participants begin to crack. One survivalist's shelter turns into an unbearable "green monster", while another takes extreme measures waging war on an uninvited guest.
While some of the survivalists enjoy a bonanza of food, others are driven to increasingly desperate measures to sustain themselves. One hunter braves dangerous heights to stalk his prey, and another turns to one of Mongolia's most revolting food sources.
As winter draws near, food becomes scarce and the survivalists must catch any game that comes their way, no matter the size. But lack of food isn't the only challenge, as the lack of companionship drives one participant to face his biggest fear.
As food sources disappear, hunger drives the remaining participants to a new low. One attempts a risky climb into wolf territory in search of food and another contends with a potentially game-ending health issue.
