In 2009 11 ordinary people set out to conquer a world first - to be the first people in history to walk Namibia's Skeleton Coast unsupported. They had to carry all their own supplies over 500km, they had to turn the sea into drinking water - and they had to film every dramatic high and low for a documentary.
But their story doesn't stop there.
Today we reunite the team, bringing them face to face with their experiences and painful memories and bringing them together to confront each other again.
Have their lives changed and how do they feel about each other now?
