American history teacher Kate lives in Canada with her fiancé Charlie, a doctor. When Charlie urges her to accompany him to Paris for an upcoming conference, she declines, partly due to her fear of flying, lactose intolerance and her pending application to become a Canadian citizen. Days later, Charlie calls Kate, saying he has fallen in love with a French woman, Juliette, and will not be returning. Determined to win him back, Kate boards a flight to Paris and is seated next to smarmy Frenchman Luc Teyssier, whom she instantly dislikes. Luc, who comes from a family of vintners, is smuggling a stolen diamond necklace in an American grape vine. He plans to sell the necklace and use the vine to create his own vineyard. Knowing Kate is unlikely to be searched at customs, he hides them in her bag. At the airport in Paris, Luc is spotted by Inspector Jean-Paul Cardon, who offers him a ride home and searches his bag for signs of criminality. Cardon is aware of Luc's profession but encourages him to stop and is unwilling to arrest him because Luc once saved his life. Kate waits for Charlie in the lobby of his hotel, but faints when she sees him kissing the beautiful, glamorous Juliette. A French thief, Bob, steals her luggage while she's out. Luc arrives to retrieve the vine and necklace, and helps Kate identify the thief, whom Luc knows. At Bob's apartment, he admits to having sold her passport and given away her clothes, but the vine is still there. Kate attempts to get help from both the American and Canadian embassies, but she is denied help as she sought Canadian citizenship without disclosing a prior felony conviction for possession of marijuana. She books a train to Cannes to pursue Charlie, who is traveling with Juliette to meet her parents. Luc, having discovered the necklace is not with the vine and must be in Kate's bag, arrives and pretends to be interested in helping her win Charlie back. That night, Kate kisses Luc in her sleep. He is disturbed to realize his attraction to her. In the morning, Kate describes a "delicious dream," while sampling copious amounts of French cheese, but they soon make her ill. The pair get off the train at La Ravelle in
Paulhaguet, which Luc reluctantly admits is his hometown. He takes Kate to his family's vineyard. She learns about his family and that he gambled away his rights to the family vineyard in a poker game, but is knowledgeable about wine and has a clear passion for it. As they board the train for Cannes, Kate playfully reveals she found the necklace. Luc advises Kate to mimic the romantic attitudes of French women, who act indifferent toward men and play hard to get. Kate approaches Charlie and Juliette on the beach. She admits to having come to France to win Charlie back, but now claims Luc is her lover and she's realized that the life she was building with Charlie was boring and no longer interests her. That afternoon, Cardon approaches Kate, telling her the necklace is stolen and asking her to hand it over to him so that Luc will not be arrested. She convinces Luc to let her sell the necklace to Cartier. Kate has dinner with Charlie to discuss the details of dividing their shared property in Canada. He is intrigued by her newfound indifference to him, while Luc distracts Juliette. Kate and Charlie go back to her room, but Kate rejects his advances, realizing she no longer loves him. Luc goes to bed with Juliette, but stops when he calls her "Kate." The next morning, Kate tells Luc she has won Charlie back. She returns the necklace to Cardon and then gives Luc a check, supposedly from Cartier, which is actually a check for her life savings. She then leaves with Luc's gratitude and heads for the airport. Cardon approaches Luc, who witnesses Charlie and Juliette reconciling, and reveals what Kate has done for him. Luc finds Kate on the airplane and confesses his love for her. They are last seen kissing passionately on the vineyard they now own together. ==Cast==
