In the heart of the Kalahari Desert - "Land of the thirsty" to the Kalahari San (Bushmen) - water is a precious and strategic resource. Considered the 'first people', the San have survived here, since time memorial, thanks to their ancestral knowledge of water conservation in ostrich eggs. Bella, 43, is an enterprising and energetic woman of the San community. She opens for us the doors to her world and takes us to meet her uncle, Kayate, the village shaman, and her children, the pride of her heart. But fate seems set against her and her community. A few hundred kilometres from there lives another family of San. Debe, an excellent hunter and proud young father, perpetuates the traditions of his people under the kind eye of his great uncle, Chef Bobo, a wise old man who watches over the future of their community.
