In 1984, on the eve of the Winter Olympics, Joe Boylan gets lost in a blizzard on an Austrian mountainside. Joe will have to fight with everything he has to survive and be reunited with his family. How he does it reveals often typical patterns of behaviour exhibited by lost people in similar situations. Through the story of Joe’s extraordinary 48-hour battle against the wilderness, Matthew Syed examines the fascinating area of study called Lost Person Behaviour, which has changed the way search and rescue teams operate, world over. Featuring Joe Boylan, Robert J Koester, mathematician and author of Lost Person Behavior, Alistair Read from Mountain Rescue England and Wales, Neil Balderson of Lowland Rescue and Maura O'Connor, science journalist and author of Wayfinding: The Science and Mystery of How Humans Navigate the World.
