Over the course of sixteen episodes, real-life cases depict unhinged passion motivating someone enough to kill. First-hand detectives, along with friends and family closest to the victims, bring each cold-blooded story to life. In the season two premiere, the quintessential girl next door is discovered brutally killed on Thanksgiving weekend. It takes investigators over a year to uncover the dark obsession that led to her murder.
