The documentary continued the story from the previous Highland Trilogy Films, exploring the relationship between the half-white, half-native Joe Leahy, who was by then tribal leader, and his neighbours, the Ganiga people. In the documentary, Leahy and the Ganiga jointly own the Kilima plantation, a coffee plantation which by the time of Black Harvest should have been becoming profitable, but a fall in international coffee prices brought dispute as the Ganiga have to work for fewer wages. This happens simultaneously with tribal warfare breaking out.
