Adventurer and naturalist Steve Backshall embarks on one of the most dramatic and dangerous expeditions ever filmed by a BBC crew. His mission is to explore Venezuela's Tepuis - ancient, sheer-sided mountains, lost worlds cut off from the jungle below. With an elite team of rock climbers, Steve attempts the first ascent of an unclimbed wall on a remote Tepui to search for wildlife on the summit. But nobody could have predicted what would happen, nor the kinds of decisions they'd be forced to make. At the end of the documentary, Steve reunites with the climbing team for a spectacular finale: an epic abseil alongside the Angel Falls - the highest waterfall on earth.
