Three short stories ("Zelenáči 1945", "Silvestr 1948" and "Zimní vítr 1951") about members of the SNB units guarding the Šumava border in the post-war years. Ivo Toman had artistic supervision over the debutants. The theme of the third short story was made in 1959 for the film "Entry Forbidden" by František Vláčil, who was also starting at the time.
