The animation is divided into three sections. “Eternal conversation” (Dialog věčný) shows Arcimboldo-like heads gradually reducing each other to bland copies; “Passionate discourse” (Dialog vášnivý) shows a clay man and woman who dissolve into one another sexually, then quarrel and reduce themselves to a frenzied, boiling pulp; and “Exhaustive discussion” (Dialog vyčerpávající) consists of two elderly clay heads who extrude various objects on their tongues (toothbrush and toothpaste; shoe and shoelaces, etc.) and intertwine them in various combinations.
Terry Gilliam selected the film as one of the ten best animated films of all time.
