The musical version of the successful play of Oldřich Daněk was transferred to the screen by director Jiří Sequens in 1986. It takes place in the 14th century in Bohemia during the reign of King Wenceslas IV. Heroes of the story are three mercenaries who always fight on the wrong side and are always beaten, but they are moral winners of all conflicts and skirmishes.
