One participant comes face-to-face with one of Mongolia's deadliest predators, while another fights to overcome a debilitating health issue.

Participants explore new and risky food sources in Mongolia. As the survivalists begin to settle into their new remote surroundings, they realise they're not the only predators on the prowl.

Ten survivalists from previous seasons return for redemption and another chance to win the cash prize. But this time, they face the dangers of Northern Mongolia.

Family members are dropped off miles apart and must navigate the unforgiving terrain of Northern Vancouver Island to find each other; to win the $500,000 prize, the competitors must build their own shelters and forage for their own food.

The three remaining teams scramble for a long-term advantage; team members run themselves ragged with an elaborate shelter build; a team hazards the freezing waters of the Pacific on their own small craft.

As their teammates attempt to set up camp, the hikers find that Vancouver Island's terrain is even more punishing when on the move; the island beats one pair into submission, while another grapples with a devastating accident.
