Return to the Dunes tells the remarkable tale of the project to restore African elephants to their former home in South Africa. Watch the herd as they surmount dangerous obstacles that unfold in the African wilderness and follow the journey of these majestic creatures as they cross thousands of miles to a new South African park reserve. The mysteries of the world's largest land mammal are brought into question. Where do they go? What do they do? And ultimately will they survive and re-establish the old migration routes - or is the past gone forever?
