The story takes place during a war in Bohemia in 1403. On the orders of Hungarian king Sigismund, Cuman mercenaries raid the mining village of Skalitz, a major source of silver. One of the survivors of that massacre is Henry, the son of a blacksmith. Destitute and vengeful, Henry joins the service of Lord Radzig Kobyla, who leads a resistance movement against Sigismund's invasion. As Henry pursues justice for his murdered family, he becomes involved in an effort to restore Bohemia's rightful king and Sigismund's half-brother, Wenceslaus IV, to the throne.
