Overview
Cold War adversaries Col. Jack Knowles and his Russian counterpart, Col. Valachev, are stationed on opposite sides of the German-Czech border. Both men are responsible for a group of troops in their remote settings, and both have been shaped by their combat experiences and a shared aversion to their superiors' ways of doing things. After a defector is killed, things escalate into a full-fledged battle with serious geopolitical ramifications.
