Rodolphe met "Fleur de Marie", a young girl who was victim of a "owl" shrew, until she was 10 years old, then forced into prostitution to survive. To snatch it from the "Master of School" and the "Chourineur", two thugs who mishandled it, Rodolphe took "Fleur de Marie" to the countryside. But who is Rudolph followed like a shadow by Murph? What's he doing in the Parisian lowlands? What is he looking for?
