Max Skinner (RUSSELL CROWE) is a ruthless, London based bond trader who's very good at what he does, manipulating the market -- with the aide of his assistant Gemma (ARCHIE PANJABI) -- in order to make himself and his firm lots of money. But with his latest success comes the sad news that his Uncle Henry (ALBERT FINNEY) has passed away. As a boy (FREDDIE HIGHMORE), Max spent plenty of time with Henry at his chateau and vineyard in Provence, but they grew apart once Max got busy with his adult life. Being his uncle's closest blood relative, Max learns he's inherited the place, a point his best friend and savvy realtor Charlie Willis (TOM HOLLANDER) informs him could result in a tidy profit.
When Max travels there, however, he finds the place rundown despite Henry's longtime vigneron, Francis Duflot (DIDIER BOURDON), still tending to the grapes, while his wife, Ludivine (ISABELLE CANDELIER), still cares for the manor. Francis doesn't want him to sell the place, but Max thinks that with enough time -- which he now has since his trading methods have resulted in a suspension for him - and a little elbow grease, they might be able to spiffy it up enough to impress potential buyers.
Yet, two developments threaten to undermine his plans. One is the arrival of young Christie Roberts (ABBIE CORNISH) from California who claims to be Henry's illegitimate daughter and wants to learn about her dad. Since French law allows such illegitimate offspring to inherit property, Max tries to figure out whether she's telling the truth or simply trying to swindle him. Then there's alluring local restaurateur Fanny Chenal (MARION COTILLARD) who Max accidentally and unknowingly runs off the road, thus getting them off on the wrong foot. Having sworn off men and not particularly enamored with this Londoner, Fanny initially wants little to do with him.
Nevertheless, with him pouring on the charm and having plenty of time to kill where he once spent many of his childhood summers, Max does what he can to impress Fanny, all while trying to figure out what to do with the vineyard, chateau, and his life.
