Based on Actual Events Copenhagen, 1944: As the Nazi occupation of Denmark rages, two Resistance fighters - a young idealist codenamed Flame (Thure Lindhardt of Into the Wild) and tense family man Citron (Mads Mikkelsen of Casino Royale) become the underground's most proficient killers of collaborators and sympathizers. The SS is hunting them. They trust only each other. But in a time where fear and mercy must live in the shadows, will a mysterious woman and a new assignment to assassinate the head of the Gestapo lead them to the deadliest places of all? Christian Berkel (Downfall) co-stars in this white-knuckle noir thriller - based on the Holger Danske's most infamous agents - from co-writer/director Ole Christian Madsen that critics worldwide hail as an explosive saga of justice, vengeance and the moral complexities of true heroism.
