La ciudad que nunca duerme

In Chicago, the police officer Johnny Kelly (Gig Young) is unhappy with his work that pays low-salary and with his marriage. His wife Kathy Kelly (Paula Raymond) has a better salary and his mother-in-law frequently humiliates him. Johnny was forced by his father Sgt. John 'Pop' Kelly Sr. (Otto Hulett) 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 (Mala Powers), 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 (Wally Cassell), 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 (Edward Arnold) summons Johnny to participate in a scheme to arrest the thief Hayes Stewart (William Talman) and protect his younger brother Stubby Kelly (Ron Hagerthy) that has teamed-up with Hayes. However Biddel is betrayed by his ambitious wife Lydia Biddel (Marie Windsor) along the restless and busy night.

"City That Never Sleeps" is a film-noir with a good story of a cop dissatisfied with his job and wife that has the intention to give up of everything independent of the consequences and go to California with his mistress. The plot has many subplots but the conclusion is moralist and does not fit well to a film-noir. My vote is seven.
