Sue Gordon, a mountain girl on the Tennessee side of the Cumberlands, lives with her grandmother. When "Granny" dies, Sue--fulfilling Granny's dying wish--goes to Chicago to live with John Peyton, an industrialist who was at one time Sue's mother's fiancé. She finds that Peyton's employees are on strike, and one of the strike's leaders is Peyton's son, Donald, to whom she is becoming increasingly attracted. Complications ensue.
