A Far Off Place (1993) on Netflix

The witty Nonni and the stuck-up city-boy Harry are the only ones to survive a massacre of a gang of poachers among the gamekeeper's family on his lonesome farm in the savanna. Now the ruthless murderers are after them as the only witnesses. Without a means of transportation, the only way to escape is to walk through 2000 kilometers of Kalahari desert with the help of the African bushman Xhabbo. On the months-long journey ahead they not only become good friends against their differences, but also realize that every one of them has strength and skills that are required to survive.
