A documentary that is immediate and plays out like a thriller. Beautifully shot in Virunga National Park in the Eastern Congo, the story focuses on the struggles between Park Rangers and a list of adversaries including poachers, oil company goons, and an Islamic revolutionary army. The stories of the endangered gorillas and the people who struggle to protect them will break your heart and at the same time give you hope in humanity. On top of this, the editing is superb and gives the film an intensity that rivals any recent thriller.
