It's 1942. Louise Pearlie, a young widow, has come to Washington, DC, to work as a clerk for the legendary OSS, the precursor to the CIA. When, while filing, she discovers a document concerning the husband of a college friend, Rachel Bloch—a young French Jewish woman she is desperately worried about—Louise realizes she may be able to help get Rachel out of Vichy France. But then a colleague whose help Louise has enlisted is murdered, and she realizes she is on her own, unable to trust anyone.
