When composer George Harvey Bone wakes with no memory of the previous night and a bloody knife in his pocket, he worries that he has committed a crime. On the advice of Dr. Middleton, Bone agrees to relax, going to a music performance of singer Netta Longdon. Riveted by Netta, Bone agrees to write songs for her rather than his own concerto. However, Bone soon grows jealous of Netta and worries about controlling himself during his spells.
