Based on the true story of one of history's most wanted serial killers.

Step inside the mind of one of America's' most twisted murderers in this gripping retelling of the BTK Killer's reign of terror. He was a father, a husband, a preacher, and a serial killer. In 2005, after a 30-year hunt, the Wichita, Kansas, police finally apprehended one of the most elusive serial killers of the century - right in their own backyard. A dogcatcher named Dennis Rader stood accused of murdering at least ten women in the late 60s and early 70s and then disappeared. In 2005, BTK suddenly resurfaced - and the killings began again.
