Grégoire Bataille is a young promising financier who comes from a modest peasant family. After completing training and an internship in England, he decides to return to France, to his roots, and make a career in the agricultural industry. On his way, Gregoire meets Don Melchiorre, an old dairy magnate who dreams of creating an international network of companies capable of feeding the whole world. Infected by this idea and succumbing to the charms of Ornella, the patron's daughter, the young man becomes a pawn in the ambitious game of Don Melchiorre. In this dirty sphere, where economy and industry show diabolical ingenuity to avoid state control, Grégoire finds himself a witness and an unwitting actor in endless machinations , revealing all the baseness of the human soul, striving for power and might.
