Martha Berry is one of an army of polite, invisible women who go to work each day at the country's national broadcaster and get things done without fuss, fanfare, or reward. When the network prepares to launch a new radio serial, Martha is transferred to assist Quentin Quinn, the man who will write and produce the drama. But Mr. Quinn is clueless about radio and work in general. Martha steps in to hire a cast and write the scripts for the new show. Her authentic, women-focused storyline snags an ever-growing audience of loyal fans. But all too soon Martha faces exposure and must decide if she will politely remain in the shadows -- or boldly step into the spotlight.
