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.

With only the clothes on their backs & the gear in their bag, Jenny and Justin struggle to find their first meal in a week, a raging forest fire forces Mitchell and Jhoanna to flee for their lives; and Max and Linn try to surpass their predecessors.

In Morocco, Mitchell and Jhoanna endure a massive hailstorm before hunting for their biggest food victory yet. Justin and Jenny finally emerge from a three-day storm in Norway. And in Mexico, Max and Linn experience a huge bounty - and a betrayal.

In Morocco, Mitchell & Jhoanna embark on a trek through higher elevations only to have tempers flare. In Norway, Justin and Jenny try to outrun an Arctic storm. And in Mexico, Max and Linn’s gamble to build a raft to float to civilization backfires.

The survivalists make their final, desperate efforts to reach civilization.
