Years ago possibly late 80's I remember watching a film about a little white boy whoe was in an African concentration camp for some reason. He formed a choir with some on the prisoners and formed a strong friendship with a prisoner. A show was put on for all of the gaudy at the end but his friend was missing as he was being beaten to death.
Please help me find the name of this movie.

The Power of One (1992) (http://www.imdb.com/title/tt0105159/reference)
