The Secret Bride is Ruth Vincent (Barbara Stanwyck), the daughter of Governor Vincent (Arthur Byron). Attorney general Robert Sheldon (Warren William) falls in love with Ruth and they marry, but Sheldon insists that their marriage be kept secret. It seems that the Governor has been accused of accepting $10,000 in bribes, and Sheldon doesn't want to be accused of complicity while he investigates the matter. In the course of events, two murders occur, and it's up to Ruth to straighten the mess out. But how will she be able to manage this without involving herself or her secret husband in the scandal?
