For years there have been white expeditions to darkest Africa. Now there comes a black expedition to darkest Britain. In the footsteps of Stanley, in the tradition of The World About Us, and in a take-off of both, a black man's expedition now journeys along the Liverpool-Leeds canal to find the centre of Britain. On the way the intrepid explorers do what travellers and television safaris always have: they examine the quaint customs of the natives, delve into their folklore and record for posterity an exotic but fast-vanishing culture.
