In 1943, a British fighter plane crashes in Nazi-occupied France and the survivor tells a tale of friendship, war, espionage, and great courage as she relates what she must to survive while keeping secret all that she can.

Fifteen-year-old Julia Beaufort-Stuart wakes up in a hospital not knowing how she was injured, and soon befriends Euan McEwen, the Scottish Traveller boy who found her, and later, when a body is discovered, she experiences the prejudices his family has endured and tries to keep them from being framed for the crime.
