Nine-year-old Pippi lives alone in Villa Villekulla with a horse, a monkey named Mr. Nilsson, and a suitcase of gold coins. Her mother is dead, and her sea-captain father was lost at sea, though she believes he became a cannibal king. When two policemen arrive to take her to a children's home, she turns it into a game of tag, then lifts them and carries them out of her garden, and the town gives up trying to place her in care.
The book strips away adults' power to force a child to comply, because Pippi is too strong to be carried off, punished, or restrained. What remains shows which rules were arbitrary convention and which carried real value. At school she rejects 'pluttification' and rote drill as pointless, while at a coffee party she shocks the hostess's guests by gobbling a whole cake. In both scenes, the adults' authority turns out to rest on enforcement rather than reason.
She hoists the boys tormenting little Willie into a tree, beats the circus strongman Mighty Adolf, and dances with the burglars who try to rob her, then pays them gold coins. The model of power it offers is that the person who fears no one has no need to be cruel.
Pippi constantly tells outrageous lies, such as people in Egypt walking backwards or in Brazil wearing eggs on their heads. When she is challenged, she admits lying is wrong but says it slips out because she lived so long at sea. Read this way, her fabrication is not deceit but world-building, a way for a child with no parents present to author her own identity and origin story.
