The United States is still fighting World War II. Cherry Ames is still an Army Nurse, this time aloft--as a flight nurse. Cherry is reunited with her corpsman Bunce--the two of them are in sole charge of ferrying severely wounded men out of the battlefield and to the nearest Army hospital. Much to Pilot Wade Cooper's chagrin, he has been taken off bomber duty to fly the wounded to safety--until Cherry makes him see otherwise. Off duty, the nurses "adopt" 6-year-old Muriel Grainger, who has known nothing but war in her short life, and whose mother has been killed by the Germans. Her father is often out on mysterious errands that cause some to label him a "spy." Cherry makes it her risky business to find out if this is truth or rumor.
