Doris to Darlene, A Cautionary Valentine: In the candy-colored 1960s, biracial schoolgirl Doris is molded into pop star Darlene by a whiz-kid record producer who culls a top-ten hit out of Richard Wagner's "Liebestod." Rewind to the candy-colored 1860s, where Wagner is writing the melody that will become Darlene's hit song. Fast-forward to the not-so-candy-colored present, where a teenager obsesses over Darlene's music -- and his music teacher. Three dissonant decades merge into an unlikely harmony in this time-jumping pop fairy tale about the dreams and disasters behind one transcendent song.
