On Vancouver Island, a seriously injured participant weighs the risks of seeking medical help and sacrificing his shot at $500,000; danger awaits all participants as predators continue to stalk the island's newest inhabitants.

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.

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.

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.

As time presses on and temperatures drop, the final teams grapple with a strong desire to tap out; however, the $500,000 prize is hard to give up on, and the participants push themselves until one reaches the breaking point.

Desperation sinks in as the hikers struggle to make the final push to their teammates; exhaustion leads one participant straight into the path of a predator, and into a dangerous confrontation.
