In 1943, Irene Woodward abandons an abusive fiancé in New York to enlist with the Red Cross and head to Europe. She makes fast friends in training with Dorothy Dunford, a towering Midwesterner with a ferocious wit. Together they are part of an elite group of women, nicknamed Donut Dollies, who command military vehicles called Clubmobiles at the front line, providing camaraderie and a taste of home that may be the only solace before troops head into battle. After D-Day, these two intrepid friends join the Allied soldiers streaming into France. Through her friendship with Dorothy and a love affair with a courageous American fighter pilot named Hans, Irene learns to trust again. Her most fervent hope is for all three of them to survive the war intact.
