Ten new participants confront the most grueling challenge in Alone history: last 100 days in the Arctic in order to win $1,000,000. Facing a variety of predators is the first hurdle they must overcome.

Participants explore new - and risky - food sources in Mongolia. As the survivalists begin to settle into their new remote surroundings, they realize they're not the only predators on the prowl.

Ten survivalists from previous seasons return for redemption and a second chance to win the $500,000 prize. But this time, they face the dangers of Northern Mongolia, a location more wild and more remote than they've ever seen.

Mongolia shows how devastating its climate can be as a monstrous storm assails the remaining survivalists. The participants are forced into their shelters and can only hope they'll hold up to the fierce wind, rain and lightning.

Seven remaining survivalists are pushed to their limits as the weather worsens in Mongolia. One participant makes a bold gamble, turning to tree bark for sustenance, another questions his ability to continue killing for food, and one faces a dangerous predator lurking in the darkness.
