The Russo-Turkish War. A Russian corps, abandoned by everyone, is locked in the Shipka Pass. In the midst of battle, human relations between soldiers and officers become worth their weight in gold. Lieutenant of artillery Count Suzdalyev and Cossack centurion Bily were raised differently, but their concepts of honor and morality are the same: loyalty to duty and love for the Motherland mean the same to them—no empty words.
Frontline friendship grows stronger when comrades find themselves deep in the Turkish rear, where, passing through all trials, the officers must preserve their loyalty to their principles.
