Sally Trent has an illegitimate child, but cannot support her and gives the baby up for adoption. The father, Michael Gardner, leaves for China not knowing about the baby, and she assumes he has abandoned her for life. She gets a job as a torch singer, changes her name to Mimi Benton, and becomes notorious for her drinking and philadering. Mimi fills in on a children's radio program as the character "Aunt Jenny," singing and telling bedtime stories, and eventually uses the airtime to find her long lost daughter, part with her wild lifestyle, and reunite with Michael.
