Rob Riggle in Iceland (S05E04)

Rob Riggle, the comedic actor, teams up with Bear Grylls for an exhilarating expedition on Iceland's Vatnajokull Glacier. Their adventure kicks off with a helicopter flight over the stunningly named "land of fire and ice," known for its underlying volcanic activity. Once they land, Bear and Rob face the challenge of traversing treacherous ice fields, deep moulins, and perilous crevasses. With no food or materials to create a shelter, their main goal is to locate an emergency cache that has been airdropped for their survival.
