The story starts with the country ruled by the Three Fat Men in turmoil - the discontent poor are trying to start a rebellion. The instigators are Gunsmith Prospero and Tibul the Gymnast. After the arrest of Gunsmith Prospero some of the palace guards join the revolt and break the Heir Tutti's wondrous doll (the doll have the appearance of a living
girl), Dr. Gaspar Arneri - who sympathizes with the poor, even though he is quite a wealthy person - is ordered to fix the mechanism in a single night under the threat of severe punishment. He can not do this for obvious reasons and takes the doll back to the palace, but lose it on the road. In search of the doll he finds a girl in a circus who is called Suok - she looks exactly like the broken doll. Suok agrees to play the role of the doll mainly to get into the palace and save Prospero (who was kept in the palace zoo). Suok manages to save Prospero, but is caught and is sentenced to death. In the end, the rebellion sucseeds, the rule of the Three Fat Men are overthrown, and Suok and Tutti (who turned out to be her twin brother) return to the circus where they both continue to perform.
