Sunshine Nan plot
Nance Molloy's cheerful nature, in stark contrast to the slum near the cathedral where she and her parents live, earns her the nickname 'Sunshine Nan'. However, her arguments with the cathedral choirboys, led by MacPherson Clark, get her into trouble. Because she intervenes in a family feud, she and her boyfriend, Dan Lewis, are sent to a reform school for five years, and after her release she becomes a stenographer in Dan's parents' shoe factory. In the meantime, he has taken a job in the chemical department of the factory, where he invents a dyeing process that promises to make him rich.
