Engineers of the most diabolical plots; killers with the most deviant desires -- Columbia University forensic psychiatrist Dr. Michael Stone explores the murderous world of these deviant killers to find out how their desires form and what drives them to carry out their fantasies. The killers featured include Jerome Brudos, whose deviant desires started with a shoe fetish as a young boy, and ended with the brutal murder and mutilation of four women as an adult; and Jeffrey Dahmer, who infamously tortured, murdered and mutilated 17 men and boys.
