In the heart of tropical Africa, at the epicenter of a brutal civil war, lies a refuge for one of Earth’s greatest species. More than half the world’s remaining 720 mountain gorillas live in the Virunga National Park. For decades, armies, militias, and poachers fought over this land with the mountain gorillas stuck in the firing line. In 2007, their only protectors, a small but dedicated force of forest rangers, were forced to flee after rebels took over the park. Now the rangers have returned after striking a deal with the rebels. What will they find upon their return? Can the great mountain gorillas still be saved? Directed by Stefan Lovgren.
