Marion is a French photographer and Jack is an American interior designer. After a less than idyllic vacation in Italy, they stop off in Paris for two days, where Jack has to deal with a new language, a crazily unfamiliar culture, meeting Marion’s sexually frank and permissive family, and a bevy of flirtatious ex-boyfriends. In the city of lights, Jack and Marion begin to see each other in a different, less appealing light as the cultural divide between them grows. Will these two days in Paris be Jack and Marion's last days as a couple, or will they be the beginning of a new, richer life together?
