A meeting of the Hamilton family is called in response to a lawsuit brought by Mrs. Polansky, the widow of a man killed while working for the family. Although the family refuses to pay, Adell Hamilton, the youngest daughter, is attracted to the opposing lawyer, David Norton. When Adell hits David's car, they decide to have lunch together. Even though both are from good families, Adell is a pleasure loving, spoiled woman, while David is a man of principle. Adell is capable of generosity, however, and she impulsively offers to send Mrs. Polansky money every month until her case is settled. One evening, after Adell, her married sister, Corinne Walton, her brother Bob and family friend, Victor Linley, return from the opera, Bob and Victor argue about Bob's gambling debts. Bob finds a vanity case on Victor's bed that he assumes belongs to Adell. She is just about to deny ownership when Corinne signals her to say nothing. Bob thinks Victor is forcing Adell to have an affair with him in return for canceling his gambling debts. Drunkenly, he runs off to shoot Victor. Adell runs after him, but she is too late to prevent the murder. The doorman identifies Adell as the mysterious woman seen the night of the murder, and Bob confesses to murder but neither Bob nor Adell will involve Corinne. David is assigned as prosecutor of the case and when Adell is caught in a lie, she says that her brother was defending her honor. After Bob's acquittal, Adell is about to leave town, when David finds her and tells her that he knew she was lying on the stand because he overheard Victor tell Corinne their affair was over.
