Superhero Michael B. Jordan ("Fantastic Four") joins famed adventurer Bear Grylls for a 48 hour adventure in Wales. Jordan and Grylls begin their journey with a daring drop into the rough ocean waters off the coast and the tenacious team makes their way up the windswept coastline, through the jagged cliffs of Cwmorthin and to the top of the mountains for their exit. Forced to battle the elements, the two must contend with copious amounts of rain and wind and get creative about finding warmth for the evening and food for dinner.
