With only the gear they can fit into one bag, three couples are dropped in three of the most difficult environments on earth and try to survive the wild, and each other, for three weeks as they make their way back to civilization.

The couples face fire, rain and hunger with only the clothes on their backs and the gear in their bags.

The three couples are nearing the halfway point of their survival challenge but they must now face Moroccan hail storms, Norwegian ice storms and newfound dangers in the Mexican jungle.

The couples face a variety of storms across Norway, Mexico and Morocco, each resulting in both bounty and betrayal.

Tempers flare for Mitchell and Jhoanna, an arctic storm plagues Justin and Jenny and a plan backfires on Max and Linn.

As the final days of the challenge approach, the survivalist couples make their final, desperate efforts to reach civilization.
