A race is on to save Gabon's Moukalaba-Doudou National Park and the silverback gorillas that call it home. This area was once protected by a thriving oil industry, but now the logging industry is poised to move in. Ecotourism could be the only way to prevent the trees from coming down, but a team of conservationists needs to make the gorillas tolerant of humans first. Follow them as they get up-close with the gorillas, study their moves, and journey to war-torn Central African Republic to learn the secrets of successful gorilla habituation.
