He calls himself "B.T.K." which stands for Bind, Torture, Kill and for decades this bloodthirsty serial killer terrifies Wichita as he murders again and again and again. Wichita residents live in fear that they will be his next victim.

For years the BTK killer plays a cat and mouse game with law enforcement and the media taunting them as he seeks the attention he craves. But then… he makes a mistake.
