Mugabe and the White African, much of which was filmed clandestinely, tells an alarming story from one of the world’s most troubled nations. In Zimbabwe, de facto dictator Robert Mugabe has unleashed a “land reform” program aimed at driving whites from the country through violence and intimidation. One proud “white African,” however, has challenged Mugabe with human rights abuses under international law. The courage Michael Campbell and his family display as they defend their farm — in court and on the ground — makes for a film as inspiring as it is harrowing. (90:00)
