Nowak convinces Potocki to admit to Rafał's heresy. Once arrested, Rafał is given a choice: recant his belief in heliocentrism or submit to torture.

The duelist Oczy wishes for death so he can escape his hopeless world and go to heaven. His colleague finds meaning in life by observing the stars.

Gras aborts the mission, placing himself and Oczy in mortal danger from Nowak. They both flee for the mountains, where they find a stone chest.

Oczy seeks the help of Badeni, the demoted monk who incurred the Church's wrath by turning his curiosity to the riddles of the sky.

Gifted scholar Jolenta suffers discrimination as the only girl at an astronomy institute. Badeni seeks resources to prove the heliocentric theory.

Badeni offers Jolenta a chance to pursue the truth of the skies, but she is overcome with fear. Afterward, she overhears bold words from Count Piast.

A middle-aged Piast vows to prove his professor's geocentric model. In the present, he agrees to let Badeni use his records — on one condition.

Oczy tells Badeni that he is learning to read and write. Later, Badeni's claim that knowledge should be held by a select few bothers a fellow monk.

Nowak gives two rookie inquisitors a terrifying first taste of their new roles. Badeni meets with Jolenta and tells her he has completed his theory.

Nowak asks Badeni to show him his research. He inspects Badeni's premises but doesn't find anything incriminating — until he spots a certain item.

In a medical area within the inquisition chamber, a wounded Oczy awakes to see Nowak, who has kept him alive in hopes of extracting information.

Badeni must choose between revealing the location of the heretical documents on heliocentric theory or prolonging Oczy's torture at Nowak's hands.
