I Am Guilty (1921)

Connie a chorus girl, meets Robert MacNair an up-and-coming lawyer. Four years into their marriage, though still in love, MacNair neglects Connie. She attends a party while he is away on business, and when the host, Garrick, makes a play for her, she is burned accidentally trying to get away. A thief, hiding nearby, plants a revolver in her hand, and it thus appears that she has shot Garrick, but Dillon, the thief, is arrested. MacNair takes the case and through her burn discovers his wife's involvement. At the trial she confesses her part in the affair, but MacNair provides evidence that Trixie, Garrick's mistress, is the murderer.
