John Auer directed and Steve Fisher wrote this police procedural film in the vein of the popular Detective Story of two years earlier. The film juggles around four characters through a particularly bad night in a Chicago precinct -- Johnny Kelly (Gig Young), a stressed out cop ready to crack; Sally "Angel Face" Connors (Mala Powers), a cheap strumpet lounge singer; Hayes Stewart (William Talman), a former magician and present thug; Penrod Biddel (Edward Arnold), a smooth and corrupt district attorney; and Sgt. Joe (Chill Wills), an Everyman character, known as "The Voice of Chicago." The skimpy plot concerns Kelly, who is having an affair with Angel Face and is ready to quit his job and leave his wife Kathy (Paula Raymond) at the drop of a hat. In order to get quick money to escape Chicago and start life anew with Angel Face, Kelly accepts an assignment and a payment from Biddel to escort low-life Stewart across the state line.
