In the extreme South-West of Uganda is Mgahinga Gorilla National Park – a wild ecosystem drawn by the orography of three sleeping giants, the Muhavura, Gahinga and Sabinyo volcanoes, which mark the border between Uganda, Rwanda and the Democratic Republic of the Congo. Joy is a female ranger and a mother who dedicates her days to protect the National Park and more specifically to watch over the Nyakagezi family, the only family of mountain gorillas that lives in its forests.
