A docudrama about four weeks in the life of famous Czech composer Antonin Dvorak. The drama - filled with many of Dvorak's compositions - begins when the composer suddenly decides to cut a concert in London and return home. While on the train, flashbacks reveal his relationship to his wife Anna and her sister Josefina. Both women gave him inspiration, yet Dvorak is clearly troubled in some way as musical excerpts come and go in his creative mind.

Martin, a poor student, volunteers to go on a quest to find a cure for the princess Adriana, who is stricken with a strange illness. Unknown to Martin or anyone else, the princess is actually under the spell of the powerful magician Andlobrandini, who is preparing a rejuvenating elixir made from the blood of nine men's hearts.
