Leontine is reading at the kitchen table when mother comes in and orders her to do some chores, like beating the rug. When she does so out of the window, the dust and dirt fall on the downstairs neighbor. Soon, Leontine is tormenting every adult who crosses her path, as she flees from an ever-growing horde of victims.
No one knows the name of the actress who played Leontine -- 'Betty' for English-speaking audiences -- for Pathe Freres, but her insistence on having her own way, her propensity for practical jokes, and her ability to get out of the way of people whom she tormented was a constant, and always amusing.
