The screenplay is based on an authentic story of a robbery of a branch of the National Bank of Poland in Wolow. The thing took place in 1962, 12 million zlotys were stolen. For some time the perpetrators remained at large. Soon, however, the police came across their trail and the criminals were soon captured. And then the real bomb went off. It turned out that the thieves were not people listed in the police annals or even in contact with the criminal world. All the robbers had a reputation as "respectable citizens", by no means suffering from a lack of cash.
