William Powell plays William Foster, a slick attorney who stays within the law, but specializes in representing crooks and shady characters. He's adept at keeping them out of jail, winning acquittals, and having decisions reversed, thus springing criminals out of prison. He is romantically involved with dancer Irene Manners (Kay Francis), who is two-timing him, although she wants to marry him. She kills a man driving while out with her other man, Jack Defoe (Scott Kolk), who takes the blame. Unfortunately, a ring Foster had just given Irene is found at the crime scene. Foster ends up defending Jack, but when the ring is found, he thinks he is protecting Irene, so pleads guilty to jury tampering, which he had done for the first time to save Irene.
