Man vs. Wild

Grylls is dropped in the Chugach Mountains in Alaska, with skis and his usual gear. He demonstrates Glissading as he traverses snow and glaciers, and climbs down a 200ft (61m) waterfall. He catches a salmon, which he eats raw, and finds a skiff from an abandoned lodge. The skiff sinks, but he reaches the shore and is spotted by a ship.

Grylls is dropped by helicopter at the top of Mount Kilauea. Made up of an expanse of solidified lava which stretches for 33,000 acres, this environment is one of the world's most inhospitable. He first traverses lava fields, which catch his boots on fire, then heads into the jungles of Hawaii. Grylls uses a kukui nut torch to explore a lava tube and finds water, then uses smoke to placate a bee hive to get honey. Ultimately, he finds the sea (and people) by following seabirds.

Grylls parachutes into the Sierra Nevadas, simulating the situation of the hundreds of hikers who become stranded there each year. Equipped with a knife and a canteen, Grylls travels through the alpine, woodland and chaparral areas of the mountains. He unsuccessfully tries to tame a wild horse, and eats a live snake. Using techniques gleaned from the Mono Indians, he brushes his teeth with a manzanita leaf. Most of the ground he covers is traversed by river, using a raft held together by grape vine.

Grylls parachutes into the French Alps with a knife, a canteen, a cup and a flint, taking the parachute with him. He demonstrates how to survive falling into a frozen lake, how to build a snow shelter, and how to use a self arresting device to stop from plummeting into a crevasse. He also eats maggots and uses them to catch a trout. He performs a Tyrolean traverse and makes himself a pair of snow shoes out of young trees and parachute lines.

Grylls is kicked out by helicopter into the water near a deserted island in the Pacific Ocean. He demonstrates long distance swimming, shelter building and coconut harvesting. Grylls builds a bamboo raft to look for ships, and is surrounded by tiger sharks. He fishes off his raft using a fish bone hook, and shows how to signal a ship using the reflection produced by his polished knife.

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.
