Once again Edward G. Robinson takes a script from the trash bin and makes it into a palatable movie. A remake of The Mouthpiece, this is the story of a district attorney with a conscience. When he discovers that a man he's sent to the electric chair was innocent, he takes to the bottle. His assistants encourage him to get off the booze, stop prosecuting and, instead, become a defense attorney. He agrees but his first client is a notorious gangster who has been in business for so long because of leaks from Robinson's own office when he was the district attorney. Push comes to shove and soon, through multiple machinations and mishaps, Robinson becomes the defender of his former assistant on charges of murder.
