I Shouldn't Be Alive (2005)

Season 4: Episode 9

Running through the majestic splendour of the Grand Canyon the Colorado River offers construction contractor David Whittlesey with just the kind of challenge he craves. He embarks on a 3 week, 280 mile white-water rafting expedition, opting to tackle some of America's most gruelling rapids on his own. Just days away from completing his journey David's raft capsizes, gets stuck and he loses all of his life-saving supplies. As he attempts to scale a cliff face, which is his only way out, he falls and injuries himself. He is trapped, alone and knows that hypothermia could kill him before anyone even knows where he is or that his life is in danger.
