One morning, Josef K., a bank clerk, is arrested by two men, Franz and Willem, without being told the reason for his arrest. Franz and Willem go through his belonging inappropriately, to Josef K.'s annoyance. However, the men tell Josef K. that he may continue to work and move freely. Josef K. begins to suffer mental torment because he does not understand what crime he may have committed. Scene 2, Fräulein Bürstner – zwei Zimmer
After dinner, Josef K. visits his neighbor, Fräulein Bürstner, and discusses his arrest with her. She sits down at the table and begins to take notes. When there is a knock at the door, she tries to persuade her uninvited guest to leave the room. Josef K. then kisses her passionately. Scene 3, Die Vorladung – Straße
At night, Josef K. walks on the street, feeling threatened by invisible forces. A stranger walks past him without a word, but then turns around and says that there will be a little investigation regarding his situation next Saturday. Josef K. should not miss the date. Scene 4, Erste Untersuchung – Dachboden
Josef K. finds the High Court with difficulty, arriving one hour late. The court audience eagerly awaits the start of the trial. Josef K. protests furiously at the court's treatment of him. Among the listeners is a student, who suddenly makes improper advances to the wife of the court usher. The examining magistrate interrupts the trial and retires with his colleagues. The wife of the court usher assures Josef K. that she would do everything in her power to help him. The student then carries her off. After being told that the investigation of the case will continue, Josef K. curses the High Court and leaves.
Part 2
Scene 5, Der Prügler – Hausflur
Josef K. finds Franz and Willem in a dimly lit room, being subjected to corporal punishment. Josef K. believes that this is the result of his complaint about their behaviour during the arrest. Suddenly, the passer-by comes down the stairs and orders Josef K. to go directly to the court chancery. Scene 6, Der Advokat – zwei Zimmer
Josef K.'s uncle, Albert K., brings him to an old solicitor, who enjoys a high reputation. However, instead of questioning Josef K., the solicitor prefers to chat with Albert K.. Meanwhile, Josef K. is in the next room, and meets Leni, the lawyer's maid. They fall into each other's arms and kiss. Scene 7, Der Fabrikant – Büro in der Bank
Josef K. tries to continue work as a bank official, but his trial weighs so heavily on his conscience that he cannot concentrate. A client at the bank, a manufacturer, advises Josef K. to visit painter Titorelli and ask him for help. Titorelli has painted almost all of the city's notable figures and thus has important connections. Scene 8, Der Maler – Atelier
In front of Titorelli's house, Josef K. has to squeeze himself through a group of violently shrieking girls to enter the studio. Titorelli, a braggart, explains to Josef K. three ways of how the trial could end: by genuine acquittal, apparent acquittal, or protraction. He advises Josef K. to assess carefully the possibilities and should not lose any time. However, Josef K. is more confused than before. Scene 9, Im Dom und im Steinbruch
Josef K. is so desperate that he goes to the cathedral as a last resort. However, the conversation with the priest gives him no consolation. On the contrary, the priest accuses Josef K. him of seeking too much help from strangers, especially women, and that he lacks foresight. The stage is then transformed into a quarry. Two men bring in Josef K., and one of them pulls out of his frock coat a large knife. With exquisite courtesy, he passes it over Josef K's head to the other man. Then the stage goes completely dark.
Music
The choice of libretto has been regarded as to express the situation of the existentialism of the post-war era. The composer said that his work, as Kafka's novel, was to express like a parable aspects of the problem of existential guilt, turning to a psychological interpretation of original sin in dialogue. The opera is scored for soloists and orchestra. The vocal lines are declamatory, using moderately modern harmony including elements of twelve-tone serialism. The music quotes at times rhythms from dance music of the early 1950s. The orchestra consists of three flutes, two oboes, two clarinets, two bassoons, four horns, three trumpets, three trombones, tuba. timpani and percussion, piano and strings.
