Nicolaus Copernicus, the son of a Toruń merchant, is a bright and curious child. When he is ten years old, the Dutch astrologer Paul van de Volder predicts a great future for him, which develops in the boy an interest in the stars. Paul van de Volder reappears in Nikolai's life when he is already a student at the Jagiellonian University in Krakow. A battle for the student's soul begins between the charlatan astrologer and Wojciech of Brudzew and other university professors. Astrology fights with astronomy. From the doubts and questions that hound Nicholas, a discovery is born that will change the world.
