Between 1964 and 1986, Richard Kuklinski is said to have killed over 100 people. This is his story: Because of his cold-bloodedness, Kuklinski, who worked for mobster Roy Demeo, is called The Iceman. But behind the ice-cold facade is a man of principle (no women, no children) and a family man who will do anything to provide for his wife Deborah and their children. For their better future, he wants to make himself independent in the lucrative killer business with the help of fellow killer Robert Pronge. This affront does not go unpunished by mobster Roy Demeo, as Kuklinski's family is soon to find out. But Demeo has messed with the wrong hitman.
