City That Never Sleeps

In Chicago, the police officer Johnny Kelly is unhappy with his work that pays low-salary and with his marriage. His wife Kathy Kelly has a better salary and his mother-in-law frequently humiliates him. Johnny was forced by his father Sgt. John 'Pop' Kelly Sr. to join the police, but he intends to quit his job and leave his wife to flee to California with his mistress Sally "Angel Face" Connors, who dances in a night-club. When Johnny gets cold feet, Sally tells that she will move to California with the small-time actor Gregg Warren, who performs a robot in the window of the night-club where she works, and plans a show with her. During the night, the crooked lawyer Penrod Biddel summons Johnny to participate in a scheme to arrest the thief Hayes Stewart and protect his younger brother Stubby Kelly that has teamed-up with Hayes. However Biddel is betrayed by his ambitious wife Lydia Biddel along the restless and busy night.
