Sydney Wells is a successful classical violinist from Los Angeles who has been blind since she was five years old, caused by an accident with firecrackers. Fifteen years later, after celebrating conductor and pianist Simon McCullough's birthday during rehearsal, Sydney undergoes a Cornea transplantation, which causes her eyesight to return, a bit blurry at first. As time goes on, Sydney's vision begins to clear; however, she also begins experiencing terrifying visions, mostly of fire and of people dying. She also sees people that are already dead, on one occasion when a girl passes right through her. Sydney attempts to unravel the mystery of the visions, and also to convince others, primarily her visual therapist and fellow violinist, Paul Faulkner, who helps her in her quest. She knows that she is not going insane.
