Xi and his San tribe of Ju'/Hoansi bushmen are living happily in the Kalahari Desert. One day, a glass Coca-Cola bottle is carelessly thrown out of an airplane and falls to Earth unbroken. Initially, Xi's people assume this strange artifact is a "present" from the gods just as they believe plants and animals are and find many uses for it. Unlike other bounties, however, there is only one glass bottle , which causes conflict within the tribe. Consequently, Xi confers with elders and agrees to make a pilgrimage to the edge of the world and dispose of the supposedly cursed thing.
