Composer Antonín Dvorák (
Josef Vinklár) conducts a rehearsal at the Royal Albert Hall in London, where a series of his musical pieces is to be performed. He is suddenly being haunted by a vicious feeling expressed by four tones f-ges-e-f. He decides to immediately return back home with his wife Anna (
Jana Hlavácková). On the train back home he immerses in his long forgotten memories. Fifteen years ago, when he was a violinist at a theatre orchestra, he got fascinated by the beauty and performance of an actress Josefina Cermáková (
Jana Hlavácová). Being captivated by her appearance, he carried on playing even after the orchestra had finished. Josefina got later married to Earl Kounic (
Svatopluk Benes), and her younger sister Anna married Dvorák.
