Richard (Pierce Brosnan) and Kate Jones (Emma Thompson) are divorcees with two children Sophie and Matt. Richard's company is sold to a corrupt French businessman, Vincent (Laurent Lafitte), and the company's pension plan is lost, including all of Richard and Kate's investments for the whole family. They go to Paris and confront Vincent, where Vincent does not deny all the things he did legally, if not morally. Richard and Kate plot to get their money back. They find out that Vincent is marrying his beautiful girlfriend, Manon (Louise Bourgoin). They plan to steal the diamond Vincent gave to Manon, which is worth over $10 million, intending for this to replace the pension money Vincent took from the company.
