A kid born to defend the Church discovers the Church has been lying about everything. Watching Rafał piece together the actual shape of the world while everyone around him burns for saying the same thing creates a suffocation that never breaks. The show doesn't make him a hero for his discovery, it makes him face the cost of knowing something nobody wants to hear.

In 15th-century Poland, the powerful Church holds geocentrism as the only truth, and those who hold heretical ideas can be burned at the stake. Rafał, a twelve-year-old prodigy who values reason over emotion, announces he will study theology, the most prestigious field of his day. A meeting with a mysterious man changes his course, stirring a passion for astronomy and a wish to show that the Earth moves around the Sun. As he chases precise calculations and evidence for a heliocentric model, he must keep his work hidden or share the grim fate of other heretics. The result is a period drama about the danger of pursuing forbidden ideas.
