Katie Nolan is a hard-working housewife who scrubs the floors of her tenement building and collects rags for sale to a scrap fabric dealer in order to provide for her family. She's married to Johnny Nolan, a happy-go-lucky, charming man who means well, but dreams his way through life, rather than find steady employment. He is also an alcoholic. On the rare occasions he finds work as a singing waiter, everything he earns usually ends up in his drinking, much to Katie's despair. The couple have two children: 13-year-old Francie, who idolizes her father; and 12-year-old Neeley. Tense and frustrated, Katie is often sharper with the children than she means to be, while Johnny is gentle, generous, and indulgent, especially with Francie.
