Shortly after Emperor Sigismund of Luxembourg finally sat on the Czech throne, he dies. His beautiful and sensual wife Barbora Celská is scheming behind his back and wants to seize the government in Bohemia and Hungary. Not only her lover Michal Országh, but especially the Hussite nobles Hynce Ptáček from Pirkštejn and Aleš Holický from Šternberk help her in this. Will the emperor establish Albrecht Habsburg as his successor, or will Barbora succeed in thwarting his plans and seizing power? Under the impression of the execution of Jan Roháč of Dubá, resistance against Zikmund rises again in Bohemia. It seems that the conspirators could not have chosen a better moment to carry out their plans.
