A lecturer is quoting extensive sections from the Criminal Code, concerning espionage against Czechoslovakia and the socialist countries, meeting the audience with possible punishment for such crimes. American and West German intelligence agencies take on Czechoslovak citizens, as it is demonstrated on the example of a deserter Karel Navrátil. The young man fled across the border, ending up at the refugee camp in Zirndorf. He was there hired by agent Williams, who took him to Frankfurt. Karel received an identity card with a false name Josef Müller, and Williams regularly interviewed him on the Czechoslovak army. Karel left his wife and child back in Prague, but a letter from his wife made him come home. Before he came home, he had undersigned an agreement on cooperation with the American agency and received espionage training and to secret making contacts. He returned home moved together with his family to the city of Beroun, and accepted a job of a taxi driver. Navrátil cooperated with another agent, a German citizen Kurt Vorbach, who was visiting his relatives in Czechoslovakia. Vorbach, in exchange for a contribution to a new car, received a lot of secret military information from Navrátil's nephew Mirek. Both men were very careful in meeting each other, but Czechoslovak counterespionage traced them, arrested and convicted them of spying activities.
