Skylark/Pacsirta, a woman doomed to become a spinster, is away for a week, which brings unexpected liberation and happiness to her parents who can no longer disregard the tragedy of their whole life.

The film, taking place in 1950, presents the story of Father Leopold and the monks of his order struggling to once again revive Christianity in a country trying to scrape itself together after the war. Initially, the communist powers do not hinder their work, and the Church was even able to regain possession of holy objects hidden during the war. This "peaceful" state does not last long. Father Leopold is arrested on trumped up charges, and in order to break him, he is subjected to cruel torture. His former student, Lieutenant Keller, who turned his back on religion and now believes in the socialist system, is appointed - upon the command of Major Fyodorov - to extract a confession of guilt. But the Father's perseverance and resistance changes everything.
