he 1920's and 30's career of singer Helen Morgan is followed from her early days singing outdoors in a carnival, through her speak-easy and chorus-girl days, to her stardom on Broadway in Ziegfeld's "Show Boat". Her involvement with Larry Maddux, a gin-runner and con-man, and Russell Wade, a prominent, married New York lawyer, and her decline thanks to these failed romances and alcohol are punctuated by performances of many of the songs she made famous.
