In 1943, Irene Woodward abandons an abusive fiance 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.
