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.

As five new survivalists begin their first days in the Mackenzie River Delta they are met with an abundance of challenges in the uncharted Arctic terrain. When opportunity presents itself to the participants, will they be able to capitalize on the moment? One participant loses a critical item while another embarks on the hunt of a lifetime.

Between the fast-approaching Arctic Winter and hunger setting in, the participants double down on their efforts for survival; procuring food becomes an urgent necessity after survivalists go days without nourishment.

As the survivalists enter the second week of the competition, new challenges and opportunities arise while they battle to maintain focus. As some participants get raided by unwelcome visitors, one survivalist gets another chance at the shot of a lifetime.

As the season begins to change, one participant is forced to take on a massive and risky project. Meanwhile, a pack of wolves interrupts the tranquility of the Arctic night and spells trouble for one survivalist.

As the competition continues to drain the survivalists, they soon face a reckoning with the strategies they've implemented. All of them seem to be teetering over the edge, though one survivalist is overwhelmed by their frustrating performance.

The call of home grows stronger as the harsh realities of remote Arctic living set in for some participants. One survivalist finally gets their chance at big game, while another is caught off guard by a false sense of security.

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.

With only four people remaining, food insecurity reaches an all-time high. One participant's prized harvest is pilfered, while another survivalist battles a debilitating sickness brought on by an unfortunate source.

As the river finally begins to freeze, the remaining survivalists struggle with the loss of daylight. One participant's snare line gets stalked by a vicious predator, while another devises a plan to defeat a longstanding enemy.

The Arctic's frozen landscape continues to push the remaining survivalists to the brink. One participant finds themselves at-risk for frostbite, while another is convinced the end days are near.

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.
