We investigate how a surfer survives when a colossal wave comes crashing down on him; witness a kayaker being pinned between a rock and a raging river; learn how a novice hang glider manages to cling on for dear life; see a snowmobile adventure in the mountains turn into a nightmare in an abyss and after a life changing attack, a body surfer defies all the odds to ride the waves again. Plus, there are loads of clips from around the world showing how life can be a battle against the odds.
