Grylls drops into the swamps of Florida's Everglades, where at least 60 tourists need to be rescued each year. He trudges through the swamp and shows how to construct shelter, deal with razor-sharp sawgrass, get out of a muddy sinkhole and avoid alligators and rattlesnakes. He eats frogs and cooks a turtle Seminole-style.

Grylls parachutes into the extreme landscape of Iceland, the site of vicious blizzard, 50 mph (80 km/h) winds, icy glacial waters, boiling hot mud and volcanic springs. He demonstrates how to make a snow cave, find water in volcanic underground tunnels and avoid frostbite. To find food in this subarctic environment, Grylls scavenges a sheep for its eyeballs and mutton fat, and catches a ptarmigan. He demonstrates with his shoelaces the boiling of the eyeballs and mutton in the geysers, to save digestion energy and disinfect the scavenged food.

In Mexico, Grylls must find his way out of Copper Canyon, and his only supplies are a water bottle, a flint and a knife. He demonstrates how to build a simple compass and climb sheer cliffs safely. For shelter, he uses ancient caves and makes fire with a traditional "fire saw." Grylls also demonstrates techniques for finding scorpions or grubs and fishing without a rod or line.

In the Kimberley region of Australia, an area with a mixture of huge scrub deserts, dry riverbeds and red sandstone cliffs full of deep gorges, Grylls faces extreme heat, poisonous snakes and the ever present danger of dehydration. Survival tips include how to forage for food (bush tucker), build a shelter and how to prevent sunstroke. He explains why he believes drinking ones own urine can prevent death from dehydration. During his journey, Grylls observes saltwater crocodiles and endures a lightning storm.

Grylls paraglides onto the edge of the Andes and follows rivers into the Ecuadorian jungle, is attacked by huge colonies of spear-nosed bats[disambiguation needed], and observes giant weevil grubs and piranhas. He builds a bamboo bridge and a bow and arrow to successfully catch fish, but it doesn't always go his way and he's forced to ride the rapids of the Amazon on a single tree trunk.

Grylls shows how to navigate the Cairngorms region in extreme weather using ice formations and moss growth, and how to test snow slopes for avalanche potential. He uses moss to purify water and skins a red deer for shelter. For food, he traps a rabbit and cooks it to demonstrate how to prepare it. Grylls also crosses deep marshes and uses fallen trees to cross ravines.

Bear gets up close and personal with sharks in the Pacific, where he also must deal with rip currents and pounding surf.

In this special, Bear attempts his most daring mission to date when he tries to fly a paramotor glider over the world's highest mountain.

In the sun-scorched Sahara Desert, Grylls uses survival tactics of the indigenous people, including eating a scorpion and a sandfish. He also explains how to escape from quicksand.

In the desert, Grylls offers tips on skinning and disemboweling a dead camel for water.

Grylls travels to Panama, where he travels in the equatorial heat through mangrove swamps and rain forest, and endures more than 100 mosquito bites and one painful snake bite.

Survival techniques for Panama's mangrove swamps and jungle.

Grylls parachutes into Patagonia, the southernmost tip of South America, where he first encounters a vast ice field, then forages in a beech forest, wades through a frozen bog and swims through icy water.

In Patagonia, Grylls skins a hare, scales a cliff, tracks a puma, drinks dirty water, and crosses the Perito Moreno glacier, a vast frozen labyrinth of ice caves and crevasses.

In this special film Bear Grylls takes us to nature's kitchen. It seems nothing--except maybe the fat of on a camel's hump--is beyond Bear Grylls.
