La mossa del cavallo: c'era una volta Vigata

In 1877, Giovanni Bovara, the new chief inspector of the mills, is sent back from Genoa to his native town Vigata, in Sicily, where he is tasked with the investigation of illegal activities caused by an unjust tax on milling, facing the dialectal and cultural barriers of post-unification Italy. He discovers the existence of a clandestine mill and an ingenious system by which the millers are left free to evade the tax, becoming involved, little by little, in something much greater.
