Get Out Alive with Bear Grylls: Season 1, Episode 4

1 - 4: The Mountains Will Give You Strength

The seven remaining teams are taken by a door-less helicopter to the base of a raging waterfall and instructed to ascend. Meanwhile, hunger sets in, and teams rely on Bear for strength to continue. Elsewhere, one team reaches their breaking point. In the end, one team will be sent home and only one duo will remain - the team that has shown the most heart, courage, initiative and resolve in their quest to "get out alive" will claim a life-changing grand prize of $500,000.
