Voice of a Mountain is a documentary of the lives of rural Guatemalan coffee farmers who took up arms against their government in a civil war that lasted 36 years. This documentary explores Guatemala's dark history from the perspective of those who saw armed revolution as their only hope for change in a poverty-ridden nation under years of military dictatorship. Ex-combatants talk about the bleak reality of the country that led to their involvement in the war, and the response of genocide from the Guatemalan government against its people. The documentary gives insight into their motives for joining an armed conflict as interviews reveal personal accounts of struggle, hope, tragedy, and the fruits of their resistance.
