Chicago, 1938. Late one night, before the 10:00 show, the body of a prominent radio actress is found dead in the station's lounge. All the evidence points to murder and one young up-and-coming radio actress, Vivian Witchell, as the next victim. But Viv isn't the type to leave her fate in the hands of others - she's used to stealing the show. Alongside charming private detective Charlie Haverman, Vivian is thrust into a world of clues and motives, suspects and secrets. And with so much on the line, Viv finds her detective work doesn't end when the "On-Air" light goes out.
