Wildlife presenter Nigel Marven heads to China to learn about giant pandas. Nigel visits the heart of panda country in the Foping Reserve. With the help of expert trackers, he finds panda droppings and paw-prints - but the animals themselves remain elusive. There are extraordinary encounters with a giant flying squirrel and a bizarre bamboo rat, then, after days of searching, Nigel finally spots movement in the thick bamboo. Is a giant panda close by?
