Julia Jarmond (Kristin Scott Thomas) is refurbishing her in-laws' Paris apartment after her mother in-law left for assisted living. The apartment comes with a history and she wants to write about it for her magazine. Her husband's grandparents took over the apartment after the Starzynskis. In 1942, the police are gathering all the Jews into the Vélodrome d'Hiver. Sarah Starzynski locks her brother Michel in the closet and promises to return later as the family is taken by the police. She is separated from her parents. She escapes, loses her friend Rachel, finds salvation with the Dufaures, and desperate to return to her brother. In the present day, Julia's uncovering of the past causes friction within the Tezac family. Her pregnancy is causing a rift with her husband. Her investigation leads to William Rainsferd.

Sarah's story is horrific and heart-breaking. It is intense. The present day story is less compelling even with the pregnancy. It should connect to the past much more directly. Julia should be searching for the transit camp that leads directly to Sarah in the camp. Julia should find the Dufaures which leads directly to Sarah being saved by them. In short, the two timelines should be connected directly. Honestly, the present day is only interesting for what Julia finds about Sarah and its own melodrama sorta drags. This is all about Sarah for me and it would be great to have more of her story.
