Two brothers, part of a border-recognition treaty detachment after a very long war, confront and deal with the wartime acts of brutality and violence of the older brother. The older brother has been part of this war for 25 years; the younger brother has been studying to become a professor and has been comparatively sheltered from the horrors. The younger brother comes face to face with his older brother's moral deterioration, and, disturbed by the older brother's acts of war, eventually persuades (and forces) the older brother to completely atone for those actions.
