Deep in the Colorado Rockies, there's a desolate region known as Prison Valley because it is home to 15 high-security prisons. One of the prisons is a federal supermax prison which houses Unabomber Ted Kaczynski and drug lord Joaquín "El Chapo" Guzmán. The valley itself is a safe community where residents look after each other. Nevertheless, a series of murders has rocked the community members in this beautiful, mountainous region of Fremont County, Colo. "Valley of the Damned" is a six-part true crime series featuring family members, police officers, witnesses, lawyers, and journalists who come together to talk about the string of murders that occurred in their remote community -- a place where evil put down roots.
