The life of Adrien Wettach, famous in the annals of the circus under the name of Grock, world famous Swiss clown. A series of images from Épinal, retracing the career of a European artist, within the framework of world history. Lots of children, wars, an eccentric Russian countess, Countess Barinoff, who grows old admiring the clown, and a very long quibble about a party wall, all serve to highlight the star's final number.
