A Dry White Season (1989)

Ben du Toit (Donald Sutherland) is a schoolteacher who always has considered himself a man of caring and justice, at least on the individual level. When his gardener, Stanley's (Zakes Mokae's) son, Jonathan (Bekhithemba Mpofu), is brutally beaten up by the Police at a demonstration by black school children, he gradually begins to realize his own society is built on a pillar of injustice and exploitation.
