In 1520, the notorious and power-hungry Danish King Christian II (Claes Bang) is determined to seize the Swedish crown from Sten Sture, no matter what it takes. Meanwhile, sisters Freja (Alba August) and Anne (Sophie Cookson) make a solemn promise to seek revenge on the men who brutally murdered their family. Everything comes to a head in the heart of Stockholm, where the sisters are drawn into a ruthless political struggle between Sweden and Denmark that culminates in a mass execution, presided over by the mad King “Christian the Tyrant,” known as the Stockholm Bloodbath.
