This film is a high-speed endurance adventure through one of the harshest environments on Earth. Glyn Maude follows a family of brown hyenas in Botswana's desolate saltpans of the Makgadikgadi. He has collared Bom, a young male he will monitor closely as he enters adulthood and fights along with the rest of the pack to survive. The film shows these fascinating scavengers as they are rarely seen.
