"Bulgakov. The Secret of the Master" examines a mystical connection that proves to be stronger than the author's original vision. The film shows how the immortal novel stopped being an author's text and began to dictate its will to the creator, interfering with his love, relationship with the authorities, and even bringing his fateful end closer. The viewer will see how fiction inexplicably turned into reality, and how the book's prophecies materialized in Bulgakov's own life, prompting the question: who really held the pen – the man or his immortal creation?
