Sydney Wells is a successful classical violinist who has been blind since the age of five. Fifteen years later, Sydney undergoes a cornea transplant, 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. The bulk of the rest of the film concerns Sydney unravelling the mystery of the visions, and trying to convince others, primarily her visual therapist, Paul Faulkner, who becomes a helpmate in her quest. She knows that she is not going insane.
