Rise of The Warrior Apes tells the stunning twenty-year story of the fierce rivalry and unparalleled ambition behind the most formidable group of chimps ever known. Seen through the eyes of the scientists who have been filming them for 20 years, this is a privileged close-up of a secret world, deep in the African jungle. In a story never told before, we follow an elite group of influential males at the centre of the troop. As the scientists gradually uncover the secrets of their strict hierarchy they witness shocking evidence of unprecedented war-like behaviour. In an investigative approach new to Natural History we tell the shocking 20-year story of politics, infighting and war at the heart of wild chimpanzee society. Using previously unseen archive footage and intimate testimony from the scientists, this is a story of the unbreakable friendships and intense rivalries inside a mighty chimpanzee empire.
