The first part of Marcin Gutowski’s documentary series looks into a collection of several hundred extraordinary letters purchased for nearly 11 million zlotys (ca. 2,6 mln euro) - a purchase largely funded by the Polish state. The correspondence spans more than thirty years and was conducted between the Polish philosopher Anna Teresa Tymieniecka, who lived in the United States, and Cardinal Karol Wojtyła, later Pope John Paul II. Journalists from "Czarno na białym" programme were the first in the world to read the entire collection of these unique documents, which for sixteen years had been kept locked in the safe of the Director of the Polish National Library in Warsaw. How did this purchase come about — and who decided, and why, that the letters’ contents should remain undisclosed for so long?
