Person of Interest

John Reese is a former CIA operative living off the grid in NYC. When Reese is hauled into NYPD's 8th Precinct for a skirmish on the subway, he's bailed out by a man he doesn't know: Mr. Finch, a mysterious billionaire. Finch offers Reese a choice: stay on the streets and drink himself to death -- or join him in his mission to stop violent crimes before they happen. Finch has access to a secret source of information, one that identifies people who are about to be involved in violent crimes. There's just one catch: he doesn't know if these people will be the victims or the perpetrators. Skeptical but intrigued, Reese agrees to help. Together, Reese and Finch work to discover what danger is about to befall Assistant District Attorney Diane Hansen. Their actions garner the unwanted attention of NYPD homicide detective Carter -- a dedicated veteran cop who's not fond of vigilantes -- and Detective Fusco, a precinct detective who stands in the way of Reese's plans.

Finch gives Reese another social security number from the machine -- another chance to stop something terrible from happening. But there's something strange about this number. It belongs to Theresa Whitaker -- a teenage girl who was murdered two years ago. Finch claims his machine is never wrong. So why is it pointing them toward someone that it's too late to save? What does the machine know that they don't? With Detective Carter still hunting them down, Reese and Finch begin to find out what really happened to Theresa -- and discover that they might still have a chance to be there in time.

Reese goes undercover to find the threat surrounding the next person on Finch's list: a young army veteran named Joey Durban. Fresh out of the service, Joey seems to be adjusting well to life back home. He has a good job, a beautiful girlfriend, and his whole life ahead of him. But Reese and Finch soon discover that even though Joey's off the battlefield, he's still putting himself in the line of fire. It seems Joey and his army buddies are using the skills they learned in combat to commit daring heists in New York. According to Finch's machine, Joey's about to kill or be killed -- so Reese infiltrates the group to find out which.

In hot pursuit, the shooters chase them into the infamous Double B High Rises -- a city housing project that has fallen into disrepair and is now home to thugs and illegal enterprises. Reese must find a way to escape the Double B's with Charlie and get him safely across the river into Carter's hands so that Charlie can testify to what he saw and bring justice to the victim of the murder. But the mafia is dead set on killing Charlie and will stop at nothing to make sure that Charlie doesn't make it out of the Double B's alive. And when Reese loses contact with Finch, Finch must look to Detective Fusco for help.
