From 1974-1991, the city of Wichita, Kansas was gripped with fear as a violent serial killer was on the loose. The killer, known to the public by his alias BTK, was an unassuming family-man named Dennis Rader. He would attack people in their own homes before binding, torturing and ultimately killing them, seemingly for self gratification. BTK came in and out of the shadows for 30 years, taunting investigators with miniscule clues. But in a moment of overconfidence, he was finally thrown into the light.

In February 1988, a 29-year-old John Duffy was on trial for the rape and murder of three women. He was a terrifying figure, and infamous across London. His arrest brought an end to a horrific four-year crime spree across the British capital, but he was only a half a murderous duo. Duffy refused to give up the name of his accomplice, and without any leads, the police have no choice but to wait. It would be another 15 years before the other man was found guilty for his part in the heinous crimes. Over a decade later, the imprisoned Duffy has had enough, and tells investigators he will testify against his former accomplice, and friend, David Mulcahy.
