1"South Island"July 18, 2011 Bear Grylls must fling himself out of a plane and parachute to safety to reach this remote area. Crossing the country's highest mountain range and starting a fire in a waterlogged forest are just some of the unpredictable things he faces in this terrain. 2"Fire And Ice"July 25, 2011 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? 3"Red Rock Country" August 12, 2011 Bear Grylls is in red rock country - southern Utah. Armed only with a lasso, he descends a rock pinnacle and gets trapped in a narrow gorge. Crossing an arid wilderness, he's left hanging 100 ft above a ravine. And Bear's craziest airplane stunt ever! 4"Land of The Maori"August 19, 2011 Over 100 people drown each year in New Zealand, and Bear must cross a raging river on a tree trunk to head toward civilization. On his journey to safety he runs out of water, is forced to climb up active volcanic ranges and scale down a waterfall. 5"Working the Wild"November 29, 2011 Bear Grylls takes the viewer behind the scenes to meet the crew that follows his every step. Whether he's jumping from helicopters or eating the unimaginable, the camera is never far away from the action. Now the crew gets to tell their side of the story.
