Through the Jungles of Vietnam

The jungles of northern Vietnam are virtually impenetrable, and some areas have never been entered by a human being. These remote rainforests near the Laotian border have become the refuge of Vietnam's few remaining wild Asiatic black bears. Tuan, a biologist and specialist in bears and monkeys at Pu Mat National Park, embarks on an expedition to the park's pristine valleys and mountains to explore how the bears living there can be better protected.
