The prologue shows a scene from Anton's childhood, in which he goes on an adventure with his friends Pashka (Paul) and Anka (Anna) and plays a game based on melodramatic recreations of events on the unnamed medieval planet. The children live in a futuristic utopia, and the teenagers feel drawn to adventure. While the children play they find an abandoned road with a road sign reading "wrong way". Anton decides to go further and discovers remnants from World War II a skeleton of a German gunner chained to his machine gun (or so he says to his friends). Later, Anton and Pashka grow up to be observers on the aforementioned planet, Anton in the Arkanar Kingdom and Pashka in the Irukan Duchy. Anton has taken the role of Don Rumata. He visits the Drunken Den, a meeting place for observers working in the Lands Beyond the Strait (). He has the current task of investigating the disappearance of a famed scientist, Doctor Budah, who may have been kidnapped by Don Reba, the Prime Minister of Arkanar. Don Reba leads a campaign against all educated people in the kingdom, blaming them for all the calamities and misfortunes of the kingdom. Rumata feels alarmed, as the kingdom is changing into a fascist police state which would never have developed in equivalent medieval societies on Earth. Rumata has attempted to save the most talented poets, writers, doctors and scientists, smuggling them abroad into neighboring countries. However, Reba's régime murders or breaks most of his native friends.
