Twenty miles off the coast of eastern Africa, four modern-day explorers are sailing toward the unknown, the deep interior of Tanzania. They'll travel 970 miles through African terrain that is as stunning as it is fraught with danger. Using only a compass and basic maps, they will attempt to recapture the spirit of one of the world's most remarkable adventures—journalist Henry Morton Stanley's perilous 1871 journey to find Dr. Stanley Livingstone. Their historic exploration has been captured by one of the premiere storytellers of our time, Mark Burnett, for the eight-part television event, "Expedition Africa": Stanley & Livingstone.
