Mike Campbell and his lawyers describe Zimbabwe's controversial land reform program. Campbell's farm was listed for redistribution by the state based on the sole criteria of his being white.

"Mugabe and the White African," much of which was filmed clandestinely, tells an alarming story from one of the world's most troubled nations.
