Prague, the beginning of the 17th century. Rozina falls in love with Italian glass worker Nikolo, but after returning home, she gets a message that will never come to Prague. She falls for the promise of an older man to marry her, but when Nikolo does return, the tragic fate of Rozina is sealed.
An industrial short produced by Pražská železářská společnost (Prague Ironworks Company) in 1939, the film contains footage from the shorts Výroba oceli (Steel Production, 1939)—today presumed lost—and Poklady země (Treasures of the Earth, 1939), both directed by Karel Kohout.
