Season 1

Ray visits the jungles of Costa Rica, where threats to survival include heat exhaustion, dehydration and poisonous snakes.

Ray travels to northern Sweden in midwinter, an Arctic terrain colder than a household freezer, where he finds shelter under a snow-laden tree and receives survival tips from a military training instructor. Bob Thomson, a survivor of being trapped in the wreckage of a plane crash near the North Pole, describes his experience of survival.

Ray explores the story of two teenage sisters lost for two weeks after their boat was wrecked, and whose survival is accredited largely to their positive mental attitude and unshakable belief that they would come out of the experience alive.

Shipwreck survivor Steve Callaghan, who spent 76 days adrift in a life raft, tells his story of survival.

Ray journeys through the Arizona desert in the footsteps of the famous Apache warrior chief Geronimo, and shows a host of survival skills, including how to find food and water in the arid environment.

The intrepid explorer braves the hostile environment of Arnhem Land to find some of the world's deadliest snakes. He also reconstructs the story of how three airmen overcame starvation, thirst and the fearsome creatures of the wilderness when they crashed in its swampland.
