Towards the savannahs of South Africa: at the end of the slopes, meetings with remarkable men and women. If it is necessary to extract the horn of a rhinoceros to protect it, save the last white lions, or launch a plea for snakes, they commit ... and we collect their testimony. From the Drakensberg mountains to the Indian Ocean, The Explorers trace the Big Five and its wild procession. But far beyond the big beasts, it is the very spirit of the savanna that speaks to us, in the song of Zulus, or the art of women N'dbele. True cultures and wild worlds: meaning and a great show in this African exploration.
