The documentary tells the story of four characters fighting to protect Virunga National Park in the Democratic Republic of Congo, home to the world’s last mountain gorillas, from war, poaching, and the threat of oil exploration. Following gorilla caregiver André Bauma, central sector warden Rodrigue Mugaruka Katembo, chief warden Emmanuel de Merode, and the French investigative journalist Mélanie Gouby, the film focuses on the natural beauty and biodiversity of Virunga, as well as the complex political and economic issues surrounding oil exploration and armed conflict in the region.
