This film is based on a true story, depicted in the novel of the same name, "Der kom en dag" (The Day Came), written by Flemming B. Muus. Quote: On April 9, 1940, we surrendered, under protest, to an army that broke all treaties, attacked our borders, occupied our country, and seized all executive power. But soon, the will to resist was born. Groups of people came together in a common desire to help win the war and liberate our country.
