Free Solo rock-climber Alex Honnold joins Bear Grylls for a panoramic journey by way of the Swiss Alps! Alex isn't any stranger to dizzying heights, however he isn't used to falling from them, so Bear kicks off the journey with a skydive into the jagged mountains. From there, it is a six-mile trek by craggy valleys and sheer cliffs the place Bear teaches Alex the best way to survive within the wild, however the tables flip when Alex takes Bear on a hair-raising climb!
