Tucker Niles lives his life vicariously through the old-time radio shows he braodcasts each Sunday night. He is more than just a DJ, however, as his life revolves around OTR shows, conventions, and his friend, Bobby, who is on a "quest" to find lost shows that have become the Holy Grail to collectors. When Bobby is found murdered, Tucker decides to find his killer. Through the maze, and sometimes greed, of the collecting world, Tucker discovers that Bobby was close to finding the lost I Love a Mystery programs that have become the dream-find of every OTR collector. Betrayal, lies, and selfish collectors lead Tucker through a world that people seldom see to discover a "master" collector who will stop at nothing to own "the ark" of the old-time radio world.
