For two years, in Dallas, Texas, surgical patients fall victim to Christopher Duntsch, a monster with a scalpel and a medical degree. Dallas Assistant District Attorney Michelle Shughart isn't sure what to think when she is first approached with the case. Is this medical malpractice? Or an evil man with a scalpel? As she dives into the case, she is shocked to learn the volume of Duntsch's patients with bad outcomes. She quickly realizes this is much more than a doctor having a bad day.
