After several months of successful work in London and Amsterdam with American expatriate Fletcher Paige, musician Evan Horne returns to the states and settles in the San Francisco Bay Area. There he reunites with his girlfriend, FBI agent, Andie Lawrence. And Evan quickly makes inroads into the Bay Area jazz scene. Life is good until a phone call from a Los Angeles attorney turns his life upside down. Evan's old friend and former mentor, pianist Calvin Hughes, has died and named Evan as his sole beneficiary. Hughes has left him his small Hollywood house, money, and all of his possessions. But when Evan begins to play through some hand-written sheet music, he recognizes one as a song from the landmark Miles Davis recording Birth of the Cool, and another from Kind of Blue. Evan is soon on a whirlwind journey across the country to find answers from his family and to confront his mother. Was Calvin Hughes the uncredited composer of one or both of these tunes, or was it simply Hughes' transcriptions from the recordings? What was her relationship with Calvin Hughes? And just how did Jazz come into the equation?
