A historical documentary ballad, with the significant subtitle "Rebellious visionaries". Father Czeslaw and son Tadeusz devoted everything to their design passions and paid a high price for it. The film tells the story of the great friendship of two generations of geniuses who blazed trails in pioneering fields: father Czeslaw - the "Polish Icarus", created the first flying machines, and son Tadeusz - the first Polish passenger cars, the famous CWS. Together they tried to build the first Polish helicopter. They were accompanied, like all Poles after regaining independence in 1918, by great enthusiasm, faith and sincere devotion to the country. Tadeusz brought his knowledge and education straight from Paris, where he abandoned a brilliant career to serve a free country. Here he built the FT-B armored car, which supported the Polish victory in the Polish-Soviet War in 1920. Their passions and dreams were cut short by the tragedy of World War II almost at the same time. Son Tadeusz, a rebellious patriot, died in Auschwitz, and father Czeslaw died alone shortly after him. Forgotten for years, they were still a legend in narrow circles of specialists. Today, through film, the legend comes alive for everyone.
