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 and 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.

Mitchell and Johanna struggle through a 16 mile journey to a new camp, only to get caught in a hail storm. Max and Linn battle starvation and each other in the unrelenting jungle. Jenny and Justin's plan to travel higher into the mountains turns ugly.
