Set against the backdrop of April 9, 1940, a night etched in history, aging 64-year-old Colonel Birger Eriksen is in command of Oscarsborg Fortress, a critical choke point that all ships must navigate on their approach to Oslo.
After five years, the German occupation of Norway ends on 8 May 1945. The rebuilding of the nation can begin, but first the final chapter must be written. In a dark cell at Akershus Fortress sits the man who committed the greatest treason of all: Vidkun Quisling. Now he must be held accountable for his actions and the atrocities that Nazi ideology led to.
