Sydney Price comes to France to buy Château Cassell before Christmas. On her first night in Paris she meets Henri at a bookstore, and the next day she finds out he is the son of Hugo Cassell, the founder. That puts her job and her feelings in direct conflict. When the truth about her business plan comes out, the relationship breaks down because Henri no longer trusts her.
At the climax, Sydney tells Hugo the truth about the business plan and urges him not to sell his company, and she loses her job as a result. Before leaving France, she goes back to the bookstore where she first met Henri. He apologizes for not trusting her, and they reconcile.
In the final scenes, the couple open a bookstore with a champagne bar, a dream they shared. The ending brings together the film's two main symbols, books (their first meeting) and champagne (heritage and celebration), and shows that Sydney has swapped acquiring other people's businesses for building one of her own.
