The film portrays Pyotr Ilyich Tchaikovsky's homosexuality as a central source of his profound personal torment and the catalyst for his disastrous marriage. His attempts to suppress his true nature lead to immense suffering for himself and his wife, ultimately contributing to his tragic mental and physical decline. The narrative frames his queer identity primarily as a cause of unrelieved misery and societal conflict.

The film portrays a traditional heterosexual marriage as a catastrophic failure, driven by societal pressure and the protagonist's repressed homosexuality, thereby strongly critiquing traditional family norms and implicitly endorsing individual authenticity over forced conformity.

The film portrays the rigid moral codes of 19th-century Russian Orthodox Christianity as a source of immense suffering and repression for Tchaikovsky, particularly concerning his sexuality. The fervent religiosity of his wife, Antonina, is depicted as intertwined with her mental instability, contributing to the disastrous marriage and offering no positive counter-narrative of faith's virtues or solace.
