Sarah's Key recap

During the 1942 Vel d'Hiv roundup in Paris, ten-year-old Sarah Starzynski locks her little brother Michel in a cupboard, expecting to return quickly. French authorities detain and deport her parents, but Sarah escapes from a camp and reaches home too late: Michel has died. Sixty years later, American journalist Julia Jarmond investigates the roundup and discovers that her French husband's family acquired the Starzynskis' apartment after their arrest. She traces Sarah's later life in America and locates her son, William, who knows nothing of his mother's Jewish childhood. Julia's research coincides with a crisis in her marriage when her husband pressures her to end an unexpected pregnancy. William ultimately accepts the documented history and learns that Sarah's fatal car crash may have been deliberate. Julia leaves her husband, gives birth, and moves to New York. She names the baby Sarah, ensuring that the child and her hidden family story are remembered.

In July 1942, French police come to the Paris home of ten-year-old Sarah Starzynski, her parents, and her four-year-old brother Michel. Believing the family will soon return, Sarah hides Michel in a concealed cupboard, locks him in, and carries the key with her. The police take Sarah and her parents to the Vélodrome d'Hiver with thousands of other Jewish families. The prisoners are held in heat and filth without adequate water, food, or sanitation, while Sarah grows frantic about the promise she made to Michel. In 2002, American journalist Julia Jarmond is assigned to write about the roundup's sixtieth anniversary. Her work begins revealing the central role of French authorities, challenging the vaguer version of wartime history she has encountered during her years in Paris.

Sarah and her parents are transferred from the Vel d'Hiv to an internment camp. Men and women are separated, and then the children are violently taken from their mothers before the adults are deported east. Sarah remains fixed on escaping and returning to Michel, whose cupboard key she still guards. In the present, Julia researches individual families caught in the roundup while preparing to move into an apartment long owned by Bertrand's family on the rue de Saintonge. Dates and addresses begin to connect the apartment to the Jewish residents removed in 1942. Her investigation becomes personal, though Bertrand and other relatives would rather regard the occupation as closed history.

Sarah escapes the camp with another girl and is taken in by Jules and Geneviève Dufaure, who risk punishment to hide and help her. Illness claims Sarah's companion, but Sarah persuades the Dufaures to take her back to Paris. She reaches the family apartment and opens the cupboard, only to find that Michel has died there. The discovery ends the hope that sustained her through detention and escape. The Tézac family now occupies the apartment, binding their history to the Starzynskis' loss. In 2002, Julia confirms that Sarah's family lived in the home her husband is renovating. She presses beyond public archives toward the private knowledge of the Tézacs, realizing that members of the family knew more than they had told her.

Julia learns how Sarah survived the war under the protection of the Dufaures and later left France for the United States. Édouard Tézac reveals the burden his family carried after Michel was found and the efforts made to assist Sarah without openly confronting how they had gained the apartment. Julia is determined to discover what became of her. At the same time, she learns that she is pregnant. Bertrand, already emotionally distant and involved outside the marriage, insists that another child would disrupt their lives and pressures Julia to terminate the pregnancy. The demand forces her to measure the compromises of her present life against the responsibility she feels toward the silenced past.

Julia traces Sarah's American life: she married, had a son named William, and died in a road collision in 1972. William has grown up without knowing that his mother was Jewish or that her parents and brother were victims of the occupation. When Julia approaches him, he rejects the account as an intrusion and initially believes she has mistaken his mother for someone else. Documents and contact with the Dufaure family begin to establish the truth. Julia also refuses to end her pregnancy, accepting that her decision may finish her marriage to Bertrand. Her search is no longer merely an article; it has become an attempt to give living descendants the history that secrecy denied them.

William confirms that his mother was the Sarah Julia has been researching and learns the full story of the roundup, Michel's death, and the Tézac apartment. Evidence surrounding Sarah's fatal crash raises the possibility that she deliberately drove into the truck, unable to escape the grief she had hidden from her husband and son. Julia and Bertrand separate after she chooses to continue her pregnancy. She gives birth to a daughter and later settles in New York with the baby and Zoë. Some time after their first painful encounter, William meets Julia there. He discovers that the baby is named Sarah and responds to this preservation of his mother's name and story. The past remains tragic and cannot be repaired, but Sarah and Michel are no longer erased from the memories of either the Rainsferd or Tézac families.

Julia finds Sarah's son, William Rainsferd, and tells him about the 1942 roundup, Michel's death, and the connection between Sarah and the Tézac apartment. William initially rejects the account because his mother concealed her Jewish identity and her past from him, but surviving records and family testimony confirm it. He also learns that Sarah died when her car struck a truck; the circumstances suggest that her death may not have been accidental. Julia refuses Bertrand's demand that she end her unexpected pregnancy. Their marriage ends, and she later moves to New York with Zoë and her new baby. When William eventually meets Julia there, he sees that she has named the child Sarah. The shared name acknowledges the girl whose life was hidden and brings the adult son into contact with a history he can no longer unknow. Julia's investigation does not undo the deaths or the silence surrounding them, but it restores Sarah and Michel to the family's memory.
