During the colonial period in Algeria, Sergeant Bouvard helps Broussole and his two daughters, Alise and Julie, settle in Hassi Ben Okba. Demobilized, he plants vines with them. Seduced by Julie's charms, he nevertheless marries Alise because she owns the land. He protects Julie from all her lovers but cheats on Alise with Adèle, a settler's wife. Unable to bear it any longer, he runs away with Julie to Oran. The death of his father brings him back to Bou-Okba. He stays with Alise until the day when, selling his wine in Oran, he is taken over by his passion. It is Julie who will tell him to resume married life and start a family of settlers.
