Missouri's most notorious serial killer terrorised the streets of Kansas City for over two decades. In this chilling film, Piers Morgan comes face to face with Lorenzo Gilyard, a seemingly ordinary man who killed 13 times before discarding his victims on the streets. Although he is serving six life sentences, Gilyard protests his innocence despite overwhelming DNA evidence against him. Piers Morgan sets out to discover what drove this family man to kill and kill again in a remarkable interview.

Piers Morgan goes behind bars to find the truth from Alex Henriquez, a serial killer convicted of three murders in New York City. Henriquez, convicted nearly 30 years ago for murdering two girls aged 10 and 14, and a 21-year-old woman in the Bronx, has never spoken publicly about his crimes. Now Piers aims to get beneath his lies and deceit to uncover the truth.

In this film, Piers Morgan comes face-to-face with a serial killer who not only admits his heinous crimes but is willing to explore what in his psyche compelled him to commit cold-blooded murder. Throughout their encounter, Piers draws fascinating psychological revelations from Bernard Giles at every turn. Giles acknowledges that even as a teenager, he knew he was destined to kill and admits that he first experienced the nascent thrill of sexual violence as a 6 year old boy, when playing a game with his female next door neighbour.
