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.

In Alone's driest location yet, ten new participants must survive in the Great Karoo desert as they face extreme temperatures, new species of predators, and a host of exhausting challenges, all for a chance to win $500,000. With big game more abundant than ever, some play the odds, while one survivalist gets hit with a debilitating infection.

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.

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 will walk away with the $500,000 prize.

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.

With only 3 left in the competition, the participants struggle to claim the $500,000 prize. While some continue to deal with the mental game, a new predator threatens a survivalist's longevity.

The remaining survivalists push themselves to their physical limits as fish becomes scarce. But one participant takes it too far, reaching the breaking point and risking organ failure.

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.

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.

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

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 brave Alone's most terrifying location yet in pursuit of $500,000. One participant is forced to make a life-or-death decision, and all must contend with Chilko Lake's deadliest predator: the grizzly bear.
