An overgrown field and a stretch of highway connect a series of grisly murders spanning several decades as grieving families search for answers.

They know how to kill and how to cure. Inside a hospital, at home, or maybe even next door. They are trained to save lives but also know how to take them. Delve into the stories of killers who broke the Hippocratic Oath to use their medical knowledge for murder, taking the lives of often vulnerable victims instead of caring for them.
