A Broadway Lady.

Chorus girl Rosalie Ryan catches the eye of Bob Westbrook, a wealthy playboy. He proposes to her but she refuses, mainly because of his heavy drinking. However, after being brazenly insulted by his family, she accepts his proposal, just to get under their skin. She finds out that Bob's sister Phyllis is planning to run off with Martyn Edwards, a cad who once betrayed a close friend of Rosalie's. Rosalie goes to Phyllis' apartment to talk her out of it, but soon finds herself involved in, and arrested for, a murder.
