The occasion is Oberholzer's fiftieth birthday. He is a highly-respected owner of a factory which produces figurines for the garden, little dwarves and such. Suddenly there is a surprise. His younger brother, who had run away some 20 years previously, arrives in his native town accompanied by his famous travelling circus ‘Obolski.' Both he and his charming, exotic wife cause confusion in the minds of all of his conventional relatives and trouble in a number of their marriages. But soon they themselves have to deal with the same type of problem, as a young niece has started showing an effusive interest in the circus and her uncle. In the end, everything returns to normal. After a magnificent final performance, the circus departs from the little town.
