Elle was born in Paris and prefers city life over the quiet existence of the countryside. When her husband travels to his hometown of Sète in southeast France, she follows by train a few days later. Elle has a lot of time to reflect on their four-year marriage, and when she reunites with Lui, she’s ready to discuss it. Over the next few days, they talk about the meaning of love and the possibility of discontinuing their relationship. The passing of time is signaled by Elle’s changing outfits; her clothes are more sophisticated than those worn by the residents of the coastal town. A conclusion regarding the marriage is reached after several cinematic strolls by the water.
