As described in a film magazine,[3] The parents of Lorelei Knight (De Remer) are anxious to make a small fortune off of her beauty. They send her to New York to become a member of a "girl show". Bob Wharton (Powers), the dissolute son of a millionaire, falls in love with the girl. When Lorelei learns that her father is ill and money is needed, she marries Bob although she does not love him. Bob's father (Burton) cuts off his allowance and Bob is forced to go to work. The wholesomeness of Lorelei kindles a desire in Bob to become a better man. He is getting along well when Lorelei's worthless brother leads Bob back to his old life. Lorelei is about to leave him when she is persuaded by Adoree Demorest (Johns), known as the wickedest woman in New York, and Campbell Pope (Joyner), a critic in love with Adoree, to stay. When Bob learns that he is going to be a father, he conquers his desire for drink. With the birth of their son, pleasant relations resume among Bob and Lorelei.
