1918. World War I rages in Europe while Erna Jensen tends to her ordinary life at home in Bramstrup, with her simple-minded son, Kalle. One day the village constable comes to enlist Kalle for military service for the German Empire – of which Southern Jutland is a part. If Erna is to save Kalle from certain death, she must follow him through thick and thin. Upon a chance meeting with a deserting solder she trades identities. Now disguised as Private Julius Rasmussen, Erna heads for the front. In her encounters with the other soldiers and in the presence of the war, unknown sides of Erna are awoken. This is the story of a woman who won’t let a war prevent her from fighting for what she loves.
