A re-enactment of the epic journey undertaken in 1804 by two men, Lewis and Clark, whose names were ever after to be bracketed together. Leading a 45-man expedition from St Louis, Missouri, they set out to explore and open up the North-West Territories of America - at that time the home of buffalo and Indians. After a year and a half, 29 of the original team together with their Newfoundland dog reached the mouth of the Columbia River and the shores of the Pacific Ocean. It took them another year to get back to 'civilisation' - and the American North West was never the same again, for the long process of settlement was soon to begin.
