Ten survivalists from previous seasons return for a chance at redemption and a second chance to win the $500,000 prize; this time, survivalists face the dangers of Northern Mongolia, a location more wild and more remote than they've ever seen.

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.

The seven remaining survivalists are pushed to their limits as the weather worsens in Mongolia; one participant turns to tree bark for sustenance, another questions his ability to kill for food, and one faces a 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.

Some of the survivalists enjoy a bonanza of food, and others are driven to desperate measures to sustain themselves. A hunter braves dangerous heights to stalk his prey, and another turns to one of Mongolia’s most revolting food sources.

The survivalists must catch any game that comes their way, no matter the size, since winter draws near and food becomes scarce. However, the 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.

The final remaining participants face the onslaught of Mongolia’s brutal winter. Relentless hunger and savage cold test them like never before and in the end, only one will walk away with the $500,000 prize.
