It won't hurt anymore. Dr. Dante Menta has spent his life perfecting a surgical procedure that will live up to that promise-a cure for all physical pain. Greg Owens is the final patient to arrive at the doctor's remote clinical trial. After years of suffering from a back injury, Greg is hoping for a fix for his pain and an end to his reliance on painkillers. While he is awaiting his turn, the other patients go through the procedure. They don't hurt anymore, but they start to act strangely. Obsessive. Self-destructive. When patients start dying, the survivors want answers. Some need medical attention. Others want violence and revenge. Dr. Menta is ready for them, prepared to defend his life's work, and continue his life's obsession.
