He lives in Paris and speaks no French. Since his wife's death, he's marking time. His curiosity is piqued when he meets Pauline Laubie, half his age, a dance instructor. She's also a solitary person but wants the connection of family. She believes she's found that in Matthew, and she attends to him during a hospitalization. When his two adult children arrive from the U.S. to check on their father, they are certain Pauline is a gold digger, and she's confounded by the distance between father and children. The daughter heads home, the son remains. Is there any way that Pauline fits in?
