In the Sahel, the semi-arid border between the Sahara and the savanna, people mark the passage of time with ceremony and tradition. As the hot sun beats down on the Niger River delta, the annual Fulani cattle drive is underway. Young Errou Sisse must leave his girlfriend and travel hundreds of miles across parched earth with his family's cattle in search of adequate grazing land. As he travels through the desolate landscape, he and his fellow herders must survive on milk, and what little they can trade in the widely scattered villages of the Sahel. Meanwhile, another young man is hoping to mark an important passage of his own. In a cliffside Dogon village in Mali, Atime Dogolo Saye awaits the sacred dama ceremony to honor the spirits of the dead. Without participating in the dama, Atime will forever remain a boy, denied the right to raise a family of his own. Will these two young men be successful in their journeys? And will they find love when they reach journey's end.
