Ludwik Hirszfeld could share his life story with several heroes. In his fate is reflected the history of the first half of the 20th century. The hero of the film was reborn despite the fact that the events in which he lived destroyed his life and achievements. Doctor, scientist, idealist. A forgotten hero. Known in the world more widely than in Poland. A scientist "from blood", which the world divided into "better" and "worse". He made difficult choices, went against the grain, believed that the world could be better. A cosmopolitan who could have continued his scientific career in Switzerland, but chose Poland. He could have lectured in America right after the war, but returned to Poland. His fate in the Warsaw ghetto is heartbreaking. Ludwik Hirszfeld's marriage to his wife Hanna is perhaps the most important choice he made in his life.
