Ten new survivalists have a chance to win $500,000 by enduring the coldest location the series has visited: the Arctic; participants grapple with a harsh storm out of the gate.

The remaining survivalists begin feeling the effects of starvation; one participant fights to stay in the competition as her body starts to give out.

The participants' survival is threatened by new factors; one contestant must fend off a huge predator; another risks losing shelter in a horrible accident; another struggles with being totally alone.

As they close in on the one-week mark, the survivalists make some risky choices in order to eat; serious infection becomes a very real possibility, driving one participant to consider pulling out early.

While most of the participants pursue smaller, more consistent food sources, one survivalist finally has the chance to take down big game; he soon finds himself attracting unwanted attention from predators.

The survivalists get serious about hunting before the wildlife starts to disappear for the winter; one participant has a chance to make history by taking down big game, while another is set back by a nasty puncture wound.
