In cold blood, the determined former member of the Resistance, Maria Mareli, pumps six bullets into an unsuspecting grizzled woman at close range. As the remorseless killer spends the night at the police station, Maria starts telling her part of the story, recounting the dangerous life of her heroic father, Colonel Miltiadis Marelis, and the brave Greek Army officer, Nikos Loranis, during the dark first months of the Nazi Occupation of Greece. Little by little, a shocking tale of betrayal, love, and sacrifice for one's country unfolds, as a now calm Maria knows that justice is served. But, is Maria capable of forgiveness? Can an act of mercy honour those who perished in the last mission?
