Zenon Ziembiewicz, a young, budding journalist, comes to his parents' manor house for a vacation. Here he enters into an affair with the lovely Justyna Bogutówna, the daughter of a cook. When the canicule comes to an end, Zenon packs his bags and leaves for Paris to study. Returning after a year with a doctorate in political science, he makes a fast and glamorous career. He becomes the editor-in-chief of the local newspaper and, soon after, mayor of the city. He also marries Elzbieta Biecka, but still does not break up with Justyna.
