Catherine is doing a study on the effects of music on the brain. A saxophonist plays beautiful, haunting music on a New York Street corner, but is taken to the Cube when he begins to lose his ability to play. Catherine discovers that he has a benign essential tremor, and the tremor worsens with movements of intention. Also in the hospital is a man who has been struck by lightning and is now being treated for memory deficits and everyday he becomes progressively more interested in playing and listening to the violin. It is an actual alteration in his brain caused by the lightning strike. Catherine finds she is concerned about Bickman after he was shot and may have real feelings about him.
