When a beautiful woman hires CJ Floyd to look into the death of her famed DJ father, CJ soon discovers that the death of "Daddy Doo-Wop" is part of a bigger story, one that reaches back to Chicago in the fifties when the Mob called the tune. From payola to paychecks, from the dirtiest of deals to some old tapes that still might be worth gold, CJ stumbles into a world where a great melody can lead to a deadly refrain, and where someone has a murderous hit parade of his own.
