In an isolated outpost between Tajikistan and Afghanistan, in the heart of the huge Central Asian continental landmass, Alexander Sokurov filmed during several months the daily lives of a brigade of Russian army border guards. Abandoned on the frontiers of a ruined empire, they are left to face an omnipresent yet invisible enemy. A magnificent poem in five parts whose pace is set by the tensions of battle, surveillance under a merciless sun and patrols along mine-laden mountain paths, 'Spiritual Voices' is a monumental meditation on the human condition in an overwhelming environment.
