A murderer is on the loose on the streets of New York City: nicknamed the Doomsday Killer, he's claimed six victims in just two weeks, and the city is terrified. Even worse, the police are mystified: the victims have nothing in common, defying all profiling, and all that connects them is that each received a sick postcard in the mail before they died - a postcard that announced their date of death. In desperation, the FBI assigns the case to maverick agent Will Piper, once the most accomplished serial-killing expert in the bureau's history, now on a dissolute spiral to retirement.
