In this first programme, Neil travels down the Zambesi river to reveal how David Livingstone took the faith of his nation to the ends of the Earth and exploited his celebrity to end the slave trade. His was a moral mission: to reshape British values and bring commerce, Christianity and civilisation to the African continent.

Following in the footsteps of a scientific explorer who has become all but lost to history, Neil charts the remarkable story of William Speirs Bruce, one of Britain's greatest, but least-known, explorers. Bruce set out to conquer Antarctica, not for imperial glory, but to advance scientific knowledge in an era when exploration had become harnessed to national prestige

Set in the spectacular Yosemite Valley in California, this is the story of the father of the modern conservation movement and one of the founders of America's National Park movement. John Muir was a 19th-century adventurer who explored the natural world and devoted his life and work to persuade others to see the sacred beauty of his discoveries.
