Serial Killer: Devil Unchained - Season 1

When investigative journalist Maria Awes gets on a call from serial killer Todd Kohlhepp, he claims he has murdered more than his seven known victims. Awes teams up with former FBI profiler John Douglas, and Kohlhepp's former colleague and now biographer, Gary Garrett, to unravel the truth. Digging into Kohlhepp's troubled youth, Awes secures an exclusive interview with his first known rape victim in Tempe, Arizona and raises questions about another Arizona rape case that has never been solved. Meanwhile, doubts emerge whether Kohlhepp is really the Superbike Killer - a murderer who escaped detection in what became Upstate South Carolina's biggest cold case. Although he confessed to the crime, can his story be trusted, or is he taking credit for crimes he didn't commit just to be remembered as a more prolific serial killer?

Ballistic evidence doesn't match Todd Kohlhepp's own confession, and Maria Awes visits the scene of the Superbike murders. She hears from one victim's family that alleges investigators missed the chance to question and apprehend Kohlhepp for the crime, something that could have prevented at least three additional murders. Awes investigates Kohlhepp's shocking life after the Superbike murders, starting his own real estate company, amassing an arsenal of high-powered guns, murdering one young couple and the boyfriend of a young woman he held captive in a shipping container, and allegedly killing others. She also learns intimate details from a former lover and investigates whether he had an accomplice.

In the jaw-dropping finale, Maria Awes tries to identify an accomplice and accompanies Todd Kohlhepp's biographer, Gary Garrett on an emotional tour of Kohlhepp's property, where investigators had previously found the bodies of three of his victims, and where Kala Brown spent two months imprisoned in a shipping container. Soon after, Maria gets an unexpected confession straight from Kohlhepp himself about two other men he claims to have killed. Awes interviews Spartanburg Sheriff Chuck Wright about the case and he agrees to organize a search for the bodies of the additional victims. As John Douglas and Maria Awes go along with the team searching for more victims, the national media gets wind of the story which comes to a chilling conclusion.
