The play deals with the problem of the unscrupulous exploitation of the natural environment by the speculators who are represented by greedy racketeers, go-betweens and merchants who appear as voracious rodents leaving in their passage destruction and devastation. The man who undertakes to kill them is a crazy old woman of the streets of Paris, Countess Aurelia. The graphic lunatic organizes in a united front all the poor of her neighborhood, sewage-cleaners, flower girls, wandering singers, tumblers, dishwashers and waiters and with their help succeeds in throwing in the sewage ducts of Paris all the rabble of the self-seekers and free forever humanity from their presence. The play denounces the murder of the beauty and truth from a mechanic civilization, exterminating vital sources of human life such as humour, love, sentiments, the poetry of Nature, and the spontaneous simplicity. 'The Madwoman of Chaillot', undertakes in the name of poetic insanity, the responsibility of 'logical' solution for the murder of human poetry from the mechanic and technocratic barbarity.
