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 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.

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, while another turns to a revolting food source.

As winter draws near, food becomes scarce and the survivalists must catch any game that comes their way, no matter the size; lack of food isn't the only challenge, as the lack of companionship drives one participant to face his biggest fear.

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.

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 walks away with the $500,000 prize.
