Journalist Nellie Wilkerson has spent the bulk of the war in London, photographing pilots taking off and landing, and she's bored. She jumps at the chance to go to France, where the Allied forces recently landed. She enlists Jean-Paul Breslau of the French underground to take her to the frontlines. On the journey, they come upon an orphanage where nuns shelter children with disabilities. Can they help save them before the Nazis come to liquidate it?
