Socialite Elizabeth Carlton impulsively joins the Women's Army Corps to escape love's disappointments and her father's attempts to control her life. Still, she has never been one to accept discipline imposed by others—not even someone as intriguing as her new sergeant.

Sergeant Gale Rains is accustomed to challenges, but she's never had a recruit quite like this one. Rains surrendered much of her Sioux heritage to the Army to escape the hardships and pain of her youth. Now a drill instructor, her calm, steady manner and firm hand have molded women from all walks of life into WACs. But not one of them has ever touched her. Why should this spoiled party girl be any different?

With the whole world at war, victory is never certain as two women wage their own battles of will and desire.
