Life of Czechoslovak soldiers in a military unit for the so called "politically unreliable" - the Technical auxiliary battalions, aka "the black barons". Although it might seem like a political satire and it's mostly funny, it shows the reality and the absurdity of military service under the communist regime. Based on a novel by Miloslav Svandrlik.
