Jack Corr was a Mafia hitman. He took his hits on the Internet through encrypted software programmes. His son knew - he'd bugged the family home. When Jack is killed, young Harold resolves to take over the business.
In a fatal mix-up Harold executes the wife of his father's best friend, Jay Benedict, a computer games inventor. Jay vows vengeance, but no one - not the police, nor the FBI, and least of all his mother - can believe Harold is anything but an innocent boy.
As Jay attempts to paint Harold into a corner, the boy sets out on a killing spree he advertises on the Internet - it's a joyride of murder. As the body count rises the mental duel is locked. Man stalks boy - boy stalks man.
Finally Jay devises an ingenious computer-generated plan to trap Harold. Who will survive? Man or monster?
