For centuries, historians believed all Viking Warriors were men. But new remarkable, archaeological findings in Sweden reveal a startling twist to history - some Viking warriors were women, thus challenging historic presumptions about the role of women in the Viking Age. This drama-led documentary tells the story of 20-year old Viking woman Signe who, driven by revenge for the murder of her chieftain father, sets out from 10th-century Sweden on an incredible journey along the Russian river networks. The film follows Signe’s rise to military leader of Birka, the most important Viking trading town of its age.
