The central motif of the film is the escalation of the situation in Bohemia after the burning of master Jan Hus and the popular revolt against the papal authority and against the new King Sigismund.

In the beginning, we follow a servant Johanka who travels through Bohemia after execution of Jan Hus and leads the fugitives to forbidden sermons in the mountains.

Against king's orders, Žižka arms the Prague poor and priest Jan Želivský leads them to the New Town Hall, where all the prisoners are held hostage.

When Wenceslas, who was staying at a hunting lodge near the capital, learns about these revolutionary events and Jan Žižka's betrayal, he is seized with an outburst of rage, and dies of a stroke afterwards.

The Holy Roman Emperor Sigismund receives news of his brother's death while campaigning against the Turks threatening the Kingdom of Hungary from the south.

Jan Žižka and priest Václav Koranda will therefore lead a part of the radical-minded Hussites from Prague heading to Tábor a mountain located near Sezimovo Ústí.

On this road (from Plzeň to Tábor), a group of Hussites led by Žižka is ambushed near Sudoměř by units of the lord's cavalry (land cash) and Johannites from Strakonice.

The music, which was played by mayor Jiří Srnek, was arranged by the Film Symphony Orchestra and the Choir of the Czechoslovak Radio, conducted by František Belfín.
