It's also very weird, blending the surreal and the nonsensical, but then I suppose the title might suggest that anyway. The overriding impression I have of it is that it is a great criticism of the excesses of, and the insanity of, capitalism.
This is a play in two parts, the first of which takes place outside Chez Francis in the Place d'Alma, with some undesirable business terrorists plotting to blow up Paris in order to get at oil. Young Pierre is blackmailed into destroying an engineer's house, but decides to kill himself, although he is saved before even touching the water. But this is when Aurélie, La folle de Chaillot, starts to understand what is going on.
And in the second part, consulting the other 'madwomen' of Paris – La folle de Passy, La Folle de Saint-Sulpice, and La Folle de Concorde – Aurélie convinces them that she's doing the right thing by luring the real mad people (the ruthless moneymakers) into the sewers and shutting the lid down tight over them for good.
This play is an oddity whose ethos I firmly approve of.
