District Attorney Robert Sheldon is secretly married to Governor Vincent's daughter Ruth. When Dave Bredeen, Sheldon's assistant, informs him that the governor has been accused of taking a bribe and Sheldon is put in charge of the investigation, Ruth feels they should keep their marriage a secret, so that no one will think he is a prejudiced investigator. The charges against Vincent stem from money that John Holdstock's secretary, Willis Martin, deposited in Vincent's personal bank account. Everyone believes that the money was a reward for Vincent's pardon of Holdstock, and Holdstock commits suicide before he can confirm or deny this. Every piece of evidence that Sherman uncovers seems to point to Vincent's guilt, but Ruth continues to believe in her father's innocence. As Ruth waits for Sherman late one night in his apartment, she witnesses Bredeen's murder. From her vantage point, she can see that Hazel Normandie, Sherman's secretary, definitely did not do the shooting, but she refuses to testify because she would have to reveal her marriage in order to explain her presence in Sherman's apartment. Determined to clear her father's name before Hazel's trial is over, Ruth tracks down Martin. He admits that Holdstock was murdered, but before she can force him to tell Sheldon, he escapes. Sheldon sends the police after Martin and Ruth testifies in time to save Hazel from murder charges. As news of Sheldon's and Ruth's marriage makes all the newspapers, Jim Lansdale, Vincent's financier, advises him to resign his office. The police find Martin, who reveals that, goaded by Bredeen, he killed Holdstock in anger. Bredeen then forced him to deposit the money. Martin also reveals that he later killed Bredeen, but the man behind the whole set-up is Lansdale. Charges against Vincent are dropped and in disgrace, Lansdale kills himself.
