During the war, Britain, America, and other nations teamed up. They fought to stop the Germans and free France. They were known as the Allies.
Sometimes the Allies sent planes to France. They would bomb spots where the Germans were making weapons or gathering troops. The Germans shot at the planes and hit some of them. The airmen often had to parachute to the ground. They would land in enemy territory.
One day, Virginia learned a secret. People had set up a system to help Allied airmen get to safety. It was called the Comet Line. Virginia and her husband signed up to help the men escape.
