This film, chronicling the last days of Czech resistance fighter Maruska Kuderikova (played by Magda Vasaryova), is based on her diaries. Though she was tortured and eventually executed by the Nazis, her diaries indicate that she was optimistic for the humanity of her captors and did not by any means hate them. Told with simple dignity, this film makes clear why Maruska became a national hero.
In the Prague Old Town and the adjoining streets there is always plenty of life. Housewives shop, beggars arouse sympathy, the Salvation Army tries to put the godless on the road to salvation by hymns and sermons, and Ferdys Pistora hunts in the pockets of his fellow men and isn't even put off by the presence of an officer of the law. Ferdys sets off to burgle villa of the banker Rosenstok, but a fire breaks out in the house and Ferdys ends up saving the banker's two small children. For this he is celebrated as a hero and gets a place as an errand boy with the Rosenstoks. At home he is visited by representatives of the Salvation Army, Captain Kosterka and Terezka, with whom Ferdys instantly falls in love.
