Her patients are dying. Some are apparent suicides and others possible accidents, but rumors are flying that Dr. Zoe Goldman is an angel of death- intentionally helping hopeless cases go to a "better place"- or, worse yet, a dangerously incompetent doctor. As a new psychiatry fellow at the local correctional facility, Zoe is still learning the ropes while watching her back to avoid some dangerous prisoners. As the deaths mount up, Zoe is wracked with horror and guilt, feverishly trying to figure out what is going wrong and even questioning her own sanity. What Zoe doesn't realize is that someone is targeting her patients to get to her. Someone who has access to her deepest secrets and fears. Someone who will stop at nothing to take everything Zoe has, even her life.
