Dívčí Válka (2013)

The year was 1420; wars between Roman Catholic states and Hussites (followers of religious reformer Jan Hus, who was arrested and executed by the Council of Constance), known as Hussite Wars or Bohemian Wars, were intense and cruel. A small Bohemian village was attacked and slaughtered by Knights Hospitallers. Twelve year old Šárka, the sole survivor of the village, was rescued and picked up by a band of mercenaries led by Jan Žižka, military leader of Hussites. Trained by Žižka and other Hussite veterans, Šárka learned the basics of using firearms and became a soldier, sworn to avenge her families and herself against invading Holy Roman Empire troops.
