Jake Gyllenhaal is Bear's latest guest/victim but he proves to be a willing participant in every dangerous or revolting activity Bear can dream up to challenge Jake's acrophobia. He and Bear are lowered from a helicopter into a frozen wilderness in Iceland. There, Bear lowers Jake into an ice hole, then has him explore an ice cave and investigate a rotting carcass. Back up top Jake gets to eat a worm, wade across a glacier fed river, dig out a snow shelter by hand and crawl cross a gorge on a rope. Then it's a windy ride home dangling on a rope from a rescue ...
After parachuting into the heart of New Zealand Bear heads for the west coast. He soon encounters a raging river hedged in by steep ravines. After slipping off one rock wall into a pool of water and electing to jump rather than fall from a second he encounters a third, even higher wall. Then there's the matter of crossing the river which he attempts twice in Bear's own precarious style. But ultimately there's no alternative to a swim in the glacier fed river.
Bear traverses Iceland's glaciers where he encounters freezing ice crevasses, boiling mud pits, frigid rivers and volcanic steam vents. But there's no getting around that it's cold so Bear builds a hot tub and strips down for a soak. All warmed up it's time for a walk in the rain and a climb down a waterfall.
Oops, Bear forgot his parachute and the pilot doesn't want to stop so Bear has to climb out of his DC-3 as it touches down on the Mohave Plateau in southern Utah. There he descends cliffs, unstable slopes and a maze of slot canyons. But Bear's oft sought river road proves to be his greatest challenge on this excursion.
On New Zealand's North Island Bear finds no shortage of water and wildlife for food but it is by no means safe or friendly. Still, he has fun navigating waterfalls and river gorges including some cliff diving and chilly swims.
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.
