Stockholm Bloodbath: In 1520, the notorious and power-hungry Danish King Christian II is determined to seize the Swedish crown from Sten Sture, no matter what it takes. Meanwhile, sisters Freja and Anne 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.
