Mildred Vandeburg, an heiress who devotes her time to a hospital that she has built in the slums, breaks her engagement to her fiancé, T. Huntington Forbes, because Forbes is only interested in horses and sports. Meeda Jones, a nurse employed in Mildred's hospital, is married to a criminal named Spike, who steals some jewels and convinces his brother Dan to fence them for him. When Dan is killed as the police try to arrest him, his wife dies of shock, leaving their baby girl homeless. To help the baby, Mildred decides to take her to Forbes's home, where she informs her former fiancé that there is a "lady in the library" waiting for him.
