Using a vast wealth of intelligence gathering resources, Alex finds people who have a motive for killing their enemies and then commits the murder without the "beneficiary's" knowledge. He sends them an invoice for $100,000 with a threat that nonpayment will result in being framed for the murder, a crime they had the most motive to commit. Police Commander, Tim Murtaugh, had been the unwitting recipient of Alex's "services" years before and now must find the killer who has his sights again set on Tim and his wife.
