Plastic surgeon Terry Dubrow ("Botched") returns as host of this true-crime series, which opens a 12-episode sophomore season with more stories of crimes committed by medical professionals. This season, Dubrow uses his medical expertise to take viewers into the mind of each killer, while investigating why these villains committed their crimes and how authorities stopped them. Cases include a surgeon who performed invasive surgeries in highly unsanitary conditions, and a doctor who over-prescribed opioids to unsuspecting college students.
