Giant gorillas are remarkable primates. Males routinely weigh more than 200 kilograms. It was once believed that these mighty apes lived only on the ground. But it was discovered that gorillas living in the tropical rainforests of the African nation of Gabon can climb trees as tall as 30 meters in search of leaves and fruit to feed on. This program illuminates many details of gorillas' arboreal lives. Following a large family of gorillas over nine years, touching stories of compassion are revealed, such as the support a young gorilla receives from the rest of its family after losing an arm in a severe accident.
