"Charlotte Gray" is the dramatic film set in both England and France in World War II. The story begins when a Scottish woman named Charlotte Gray is on her way to London to work as a medical receptionist at a doctor's office on Harley Street. On the journey south to London she meets a man on the train. During their conversation she tells him that during her education she learned to speak fluent French. By the time Miss Gray arrives in London, it is clear that the war did not dampen the social life of the city.
At a party Miss Gray meets a Flight Lieutenant Gregory of the RAF and to her surprise he is the same man she met earlier on her journey down to London. It is not long after that she is recruited in the SOE. Soon after completing her training, she learns that Gregory was shot down over German Occupied France.
Her mission into France does not start very smoothly when she misses the drop zone, in part caused by two boys playing with flashlights. This alone could easily blow her cover as a French Civilian, but luckily does not. She finds a local man named Julien Levade who helps her blend into the local village life, however, soon there is trouble.
One day a local Vichy French Official arrives in the village in order to meet a quota of Jews to be rounded up in the area. At the same time the local Schoolmaster named Renech discovers the two boys staying with Julien's father are Jewish and threatens the elder Levade to turn them in. By refusing to turn them in, Monsiuer Levade was taken as well as the two boys. By the time the war in Europe ended in 1945, Charlotte returns to the village to find Julien and tell him her true identity.
