But when Rose- Lynn tries to hold down a housekeeping job, her boss (Sophie Okonedo) hears her singing and becomes an unlikely supporter, intent on getting her to Nashville despite the long odds. Caught between hope and responsibility, Rose-Lynn must find her place without abandoning her raw talent and grand ambitions.
