Through his research, Falk Marna has succeeded in using bacteria to synthesize a fluid that reveals a form of communication in carbon atoms. Falk thinks he knows what guides the souls of his fellow human beings deep inside. Yolanda, his colleague, considers the stimulated state of the carbon atoms not as a conspiracy of nature but as a delusional projection of him. Falk connects the process with the experiments of Arthur Eddington in 1919 on the island of Príncipe, where he wanted to prove Einstein’s theory of relativity. Eddington was able to show the orbital light deflection using the Hyades during a solar eclipse. Falk increasingly isolates himself on his inner island Príncipe as he approaches the evidence.
