The adventure begins as ten new participants are abandoned in the remote wilderness of Patagonia to live as long as they possibly can. Faced with the unforgiving terrain of a foreign land and the onset of winter, each must act quickly to adapt to their new environment in order to survive.

Ten new participants return to the History Channel's #1 summer survival series. In Big River, Labrador, the participants face the stalking predator, the Polar bear.

As hunger rapidly sets in, the remaining participants rush to get familiar with the land and do whatever it takes to secure food; one survivalist thinks outside the box for dinner; one participant struggles and makes a costly mistake.

As Labrador's winter draws near, the participants split their time between building permanent shelters and getting food; many participants struggle; one allows an opportunity to slip through their fingers; one braces for a deadly encounter.

As they continue to settle into their new surroundings, the participants aim to procure food for the long haul; one survivalist risks hypothermia by entering the frigid Labrador waters while another realizes they bit off more than they can chew.

The participants continue to look for new ways to hunt, but also to preserve their food sources; one survivalist leans heavily on a taxing shelter build, while another pauses their own work for some much needed sustenance.

As the participants close in on the first thirty days, the lack of food and the desire to go home grows ever stronger in Labrador the competitors continue to make each opportunity for food count; the need for preservation has one getting creative.

With the competition in its final stage, only one survivalist's resolve can secure them the $500,000 prize. As the temperature dips well below freezing, the river stops paying dividends. The three participants are forced to weigh tapping out versus a lifetime of regret.

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.

As temperatures drop to the lowest point yet, the lake freezes, cutting off resources and threatening the safety of the survivalists. Each participant's grit and resourcefulness is tested by the unrelenting cold, causing one survivalist to hit their breaking point much sooner than expected.

The final three survivalists continue to battle weight loss, extreme temperatures, and predators to remain in the fight for the $500,000 prize. The punishing cold makes getting food harder than ever before and a devastating catastrophe causes one participant to lose everything. The remaining survivalists push on, but in the end, only one is able to conquer the Arctic and emerge victorious.

A severe lack of food takes a toll on the remaining participants. Many of them haven’t eaten in days and it’s beginning to impair their mental and physical capabilities, pushing some to the edge of surrender.

In a new twist, seven family member pairs are dropped miles apart on Northern Vancouver Island and must find each other. To win the $500,000 prize, they must survive the island's unforgiving terrain and deadly predators together.

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.

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.

As they approach the one month mark, the participants' survival is threatened by new factors. One contestant is forced to defend themselves from a huge predator. Another risks losing their shelter in a horrible accident. And another struggles with the most challenging element of them all: being totally alone.

The remaining survivalists begin feeling the effects of starvation. One participant fights to stay in the competition as her body starts to give out, while another, who has an abundance of food, shockingly continues to lose weight.

Ten new participants compete to win $500,000 in the show's most remote location yet, northern Saskatchewan; as the survivalists set out into the wilderness searching for food and shelter, one participant makes a costly mistake.

The survivalists find themselves pivoting as new challenges test their strength; one participant loses a valuable resource, while another is pushed to their absolute limit.

As the remaining survivalists near day 50, conditions at Reindeer Lake intensify. Desperation rises as the temperatures continue to drop, and personal demons bubble to the surface. One participant's shelter is endangered by the elements, while an unwelcome predator visits another.

The three remaining survivalists brace themselves for the fight to the finish. One participant finds it impossible to stay warm, while others risk it all on the ice. Though they all push themselves to their limits, only one can claim the $500,000 prize.

In Alone's most remote location, ten new survivalists must survive north of the Arctic Circle as they face the cold and dwindling sun for a chance to win $500,000. While the participants prepare for frigid temperatures and dangerous predators, the Mackenzie River Delta begins to test each survivalist. With signs of grizzly bears and wolves all around, one survivalist learns the biggest danger could be himself.

With new weather patterns looming, the days are numbered for those counting on foraging to pull them through. One survivalist is left confused as the Arctic takes back its gift, while another unexpectedly finds a second chance at a missed opportunity.

Faced with skittish game and unfamiliar plants, the final group of survivalists quickly learns their earliest strategies will be met with unforgiving resistance.
