May 1945, Ljubljana. Following the end of World War II and the communist seizure of power, many opponents of communism flee Yugoslavia, retreating to Austrian Carinthia toward the British Allies. On a medical train from Ljubljana, alongside wounded members of the Home Guard, travel two physicians: Dr. Janez Janež and Dr. Valentin Meršol with his family. Their principles and consciences are put to the test as they face the brutal truth that they cannot save everyone - the survival of some will mean the death of others.
