Plot is from Wikipedia:
The film is a collision of three separate stories—the journey of a Ju/’hoansi bushman to the end of the earth to get rid of a Coca-Cola bottle, the romance between a bumbling scientist and a schoolteacher, and a band of guerrillas on the run.
Xi and his tribe of San/Bushmen relatives are living well off the land in the Kalahari Desert. They are happy because the gods have provided plenty of everything, and no one in the tribe has unfulfilled wants. One day, a glass Coke bottle is thrown out of an aeroplane and falls to earth unbroken. Initially, this strange artifact seems to be another boon from the gods—-Xi’s people find many uses for it. But unlike anything that they have had before, there is only one bottle to go around. This exposes the tribe to a hitherto unknown phenomenon, property, and they soon find themselves experiencing things they never had before: jealousy, envy, anger, hatred, even violence.
Since it has caused the tribe unhappiness on two occasions, Xi decides that the bottle is an evil thing and must be thrown off of the edge of the world. He sets out alone on his quest and encounters Western civilization for the first time. The film presents an interesting interpretation of civilization as viewed through Xi’s perceptions.
There are also plot lines about shy biologist Andrew Steyn (Marius Weyers) who is studying the local animals (which, because of his nervousness around women, he once described as “manure-collecting”); the newly hired village school teacher, a former newspaper reporter named Kate Thompson (Sandra Prinsloo); and some guerrillas led by Sam Boga (Louw Verwey), who are being pursued by government troops after an unsuccessful attempt to massacre the Cabinet of the fictional African country of Burani. Also taking a share of the limelight is Steyn’s Land Rover, dubbed the Antichrist (also “son of a mlakka”) by his assistant and mechanic, M’pudi, for its unreliability and constant need of repair. Also part of the chaos is a fresh safari tour guide named Jack Hind , who has designs on Thompson and would often steal Steyn’s thunder.
Xi happens upon a farm and, being hungry as well as oblivious to the concept of ownership, shoots a goat with a tranquilizer arrow. For this he is arrested and jailed for stealing livestock. M’pudi, who lived with the bushmen for a long time, realizes that Xi will die in the alien environment of a prison cell. He and Steyn manage to hire Xi as a tracker for the 11 weeks of his prison sentence, with the help of M’pudi, who speaks Xi’s language. Meanwhile, the guerrillas invade the school where Kate teaches and use her and her pupils as human shields for their escape by foot to the neighboring country. Steyn and Xi manage to immobilize the guerrillas as they are passing by and save Kate and the children. Steyn allows Xi to leave to continue his quest to the edge of the world.
Xi eventually finds himself at the top of a cliff with a solid layer of low-lying clouds obscuring the landscape below. This convinces Xi that he has reached the edge of the world, and he throws the bottle off the cliff. This scene was filmed at a place called God’s Window in the then Eastern Transvaal, South Africa (now Mpumalanga). This is at the edge of the escarpment between the Highveld and Lowveld of South Africa. Xi then returns to his band and receives a warm welcome.
