This National Geographic documentary journeys deep into the heart of Mozambique to chronicle the resurgence of Gorongosa National Park, a formerly idyllic wildlife sanctuary devastated by the country's long civil war. Charting the efforts of conservationists to revitalize the park, the film gets up close and personal with zebras, wildebeests, elephants, hippos and other critters as they roam Gorongosa's breathtaking landscape.
