1926. The Szkocka café in Lviv. Among the café guests is a group of mathematicians – Banach, Mazur, Ulam, Stożek, Szuder. A heated discussion is underway. These young mathematicians are employees of the Jan Kazimierz University. The world will soon hear about them. The most brilliant of them was Stefan Banach (1892-1945). Who was this brilliant self-taught man? How did he end up in Lviv? Although he was one of the most outstanding scholars of the 20th century, not many photographs depicting his interesting life have survived. To this day, he remains a little-known figure in Poland. Due to the poor photographic documentation, as well as the complete lack of film archives concerning Banach himself, it became reasonable in this case to use fictionalized scenes that recall important events in the scholar's life and bring his character closer to the audience.
