- Plot: Near the Baie de la Seine swamps, opposite the Port of Le Havre, Auguste Maroilleur, an elderly farmer, exploits 400 hectares of crop land with the help of his family, over which he rules with an iron hand. Things go awry the day he discovers one of his grandsons is involved in drug traffic. To make matters worse, the reckless youth has hidden the white powder in the Maroilleur farm. Without a moment's hesitation, Auguste gets rid of the toxic substance but, of course, the mob has different views...
