Nicolaus Copernicus and two scholars, Czesław and Miłosz, stroll through the streets of Frombork, talking and eating gingerbread cookies. When Copernicus presents his theory about the solar system to the others, the scholars agree with him and support his words. However, when Nicolaus plans to publish his theory and share it with the world, Czesław and Miłosz change their minds and try to prove him wrong.
