In a prologue, a young Max Skinner spends his summer holidays learning to appreciate the finer things in life at his Uncle Henry's vineyard estate in Provence in southeastern France. As an adult, 25 years later, Max is an aggressive, hard-working London-based investment trader. Upon his uncle's death, he is the sole beneficiary of the property. Max travels to Provence to prepare for a quick sale. He discovers that his latest financial stunt has landed him in hot water with the government and with his firm's management, necessitating a return to London. Before leaving, to assist the sale, Max hurriedly snaps photos and falls into an empty swimming pool. He is unable to escape until Fanny Chenal, whose bicycle he ran off the road with his careless driving, turns on the water supply in retaliation. The resulting delay causes Max to miss his flight. Because he fails to report in person to management, he is suspended from work and trading activities for one week.
Max must deal at the estate with a gruff yet dedicated winemaker, Francis Duflot, who fears being separated from his precious vines. Duflot pays a vineyard inspector to tell Max that the soil is bad and the vines worthless. They are surprised by the unexpected arrival of young Napa Valley oenophile Christie Roberts, who is backpacking through Europe and presents herself as Henry's previously unknown daughter.
Max believes she might lay claim to the estate. Worried about being usurped by his second-in-command in London (through whom Max continues to direct trades), Max intentionally gives the ambitious trader bad advice, which gets him fired.
Max becomes enamored of the beautiful, feisty café owner Fanny, who is rumored to have sworn off men. He successfully woos Fanny, who leaves Max the next morning expecting him to return to his life in London. A disillusioned Christie also leaves Provence, and the estate is sold. Max returns to his life in London.
Management there offers Max a choice: "Money or your life." He must choose a discharge settlement, which includes "a lot of zeros," or a partnership in the trading firm, in which he would be "made for life". Max chooses the money. He cleverly negates the estate's selling by orchestrating (through a forged letter from Henry – as a child he signed cheques for his uncle, thusly being ably to imitate his signature) that Christie has a valid claim on the property. He puts up his London residence for sale and returns to Provence, entering into a relationship with Fanny. At the estate, meanwhile, Christie and Francis must reconcile their vastly different philosophies of wine production and jointly run the vineyard.
