She moves back home to her parents and brother, a vet who is suffering from PTSD. Carrie soon joins forces with Dr. Alistair Finley, a well-respected neurosurgeon with the VA, to perform what is presented to her as ground-breaking brain surgery to reverse the affects of PTSD. As with any great medical suspense thriller, things are not always what they seem. After two of the patients who have received the surgery have rather adverse side effects and then disappear from the hospital, Carrie, along with a resourceful (and single, hunky) journalist, David, begin to investigate even as the situation becomes more dangerous.
