It is 1930s Pittsburgh, and college student Betty Roberts has won an internship at WENN, a station that specializes in radio shows. She finds that the employees of the shows are just as wacky as the characters they play on the radio. They include: Mackie Bloom, WENN's man of a thousand voices; Hilary Booth, queen of the stage who carries an over-inflated ego; Mr. Foley, WENNs sound effects man who never talks; Tom Eldridge, who is as clueless as a gnat; and Jeffery Singer, who is in a marriage of convenience with Hillary. Each week, we watch how the station members struggle to keep the station going.
