Alain is the only son of a wealthy bourgeois couple. He takes violin lessons in Ménilmontant, where he is spotted by Fleur, a poor girl: she is going to kidnap him and demand a ransom from the young man's parents, money which will be used to pay for a good lawyer for her brother accused of killing a policeman.
