Channing Tatum accompanied Bear Grylls on a 48-hour expedition in Yosemite National Park, where they hiked, explored, climbed, and rappelled off cliffs. Tatum and Grylls began their journey in a helicopter ride, later jumping out and doing backflips into the water. After reaching land, they traveled 14 miles through a dense forest to reach their destination. While in the forest, Tatum and Grylls encountered both a scorpion and a rattlesnake, both of which they killed and ate. After finally reaching their destination point, they slept on top of a cliff. The episode concludes as the two rappel down the cliff.
Bear Grylls is dropped on an ice cap covering an active volcano. In blizzard conditions he struggles to make headway, and the barren land offers little food. Can he reach civilization when faced with swollen river crossings and ever present flash floods?
