Country tailor Florian Svíčička neglects his work because of his interest in medieval history. When preparing an amateur performance at Zdislavice Castle, he gladly replaces the bailiff and plays the role of a knight. However, he ruins the performance and is shamefully banished. On his way home, he witnesses a horrific scene in the forest: two knights behead a young girl.

The master loses patience with Florian's excesses and Florian is fired from the tailoring shop. He sets off for Prague to find the girl he was with at the castle the night before. However, he does not know her name and accidentally comes to Elvíra's villa. The diva is not at home. Florian finds a love letter in the villa and thinks it is addressed to him. However, upon his return, Elvíra mercilessly throws Florian out...
