Sydney Wells (Jessica Alba) is an accomplished, independent, Los-Angeles based concert violinist. She is also blind, and has been so since childhood. As our story opens Sydney undergoes a double corneal transplant and her sight is restored.
But Sydney's happiness is short lived as unexplained shadowy and frightening images start to haunt her. Are they a passing aftermath of her surgery, Sydney's mind adjusting to sight, a product of her imagination - or something horrifyingly real? As Sydney's family and friends begin to doubt her sanity, Sydney is soon convinced that her annonymous eye donor has somehow opened the door to a terryfying world that only she can now see.
