Standby for Crime, as the title suggests, was a radio show about crimes and mysteries. It started on the early 1950s and became known for its "true story delivery" of crime stories. Like Dragnet, Gangbusters, and Mr District Attorney, Standby for Crime was also one of the most popular crime radio shows during the time it was aired.

The show's lead character was Chuck Morgan (portrayed by actor Glen Langen), an extremely convincing news anchor that works at KOP, a radio station based in Los Angeles. His friend, Police Lieutenant Bill Miggs, gave tips about hot crimes. Another important character in the series was Carol Curtis, whom Chuck referred to as "Gal Friday." Adele Jurgens, Glen Langens wife, was cast as Carol.
