Second half of the 19th century. In a small town in South Bohemia, fifth-former Jan Ratkin is living through the confusions of first love together with his classmates.

Labakan is a lazy tailor's journeyman dreaming of a life of luxury and dresses himself in fancy clothes for the rich emir, and when he sees how respectfully people greet him in the marketplace, he seizes the opportunity that unexpectedly presents itself. For he meets the Sultan's son Omar, who was brought up by the noble Cairo Pasha and is now returning home. Labakan steals the Sultan's dagger, his trademark, and sets out to find him. However, the Sultan's wife recognizes her true son and forces the Sultan to put both men to the test. Both have to prove their skill by sewing a coronation gown, which of course only the real tailor Labakan will be able to do, and so the executioner awaits him. Fortunately, it was all a dream and the foolish young man will make amends in time.

It happened during the reign of King Vladislav Jagiellon: the rebellious knight Dalibor is sentenced to death. An attempt to free him fails. This underappreciated transcription of Smetana's opera surprises with its fresh originality, even compared to much later attempts to translate musical-dramatic works to the screen.
