A group of passionate and adventurous young people leave their known worlds behind to spend 100 days in the jungles of Borneo. Their mission: saving rainforests and endangered orangutans. The odds and time is working against them. Jojo, an orphaned baby orangutan, is entrusted in their care and they must find a way to return her to her natural habitat. To achieve this, they need to build an orangutan rehabilitation centre, introduce a satellite monitoring system called Earthwatchers, start a reforestation nursery and build a global support network. Their efforts are put to the test when the bulldozers move in and threaten the future of a community living in a traditional longhouse.
