Miriam Scott is loved by two men; Robert Henderson, only son of wealthy people, and Richard Blakely, a poor but ambitious young doctor. She admits she prefers Blakely, yet decides to marry Henderson for the home and social position he can give her. Blakely’s failure to win Miriam makes him reckless. He starts gambling, gets in with a rough set who rob him and finally becomes a thief. Meanwhile Miriam marries Henderson, who gradually tires of her, and neglects her. One evening, Henderson quarrels with his wife, and leaves the house for his club. Miriam is left alone with their sick baby, which grows worse and worse.
