William Powell is a poor East Side lawyer who works his way up the ladder to assistant prosecutor. He isn't too particular how he uses and misuses the law, much to the dismay of his faithful secretary (Joan Blondell). Powell's downfall comes when he falls for a shady lady (Claire Dodd) who blackmails him for a past misdeed. He escapes prosecution with a hung jury, but the experience rekindles his conscience. With his loving secretary at his side, Powell returns to his old neighborhood to set up an honest legal practice.
