Person of Interest — Season 1

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. With Detective Carter hot on his trail, Reese is closer to getting captured than ever before as he goes on a high-risk mission that puts his life -- and Finch's -- in danger.

Reese and Finch surveil their latest POI, Dr. Megan Tillman, while she's on call and after hours to unravel the threat surrounding the promising young physician.

When the Machine produces the social security number of a judge renowned for his tough sentencing, Reese and Finch have the added challenge of investigating a POI who wants nothing to do with their brand of vigilante justice.

Reese is captivated by their newest POI - a beautiful, shrewd and remarkably resourceful woman.

Finch gets the number belonging to Charlie Burton, a high school history teacher in Brighton Beach, Brooklyn, and an unlucky witness to a Russian mafia murder. Reese, with no time to spare, rushes to Charlie's side and whisks him out of danger just as the mob descends on his apartment to silence him for good. But they can't shake the Russians that easily. 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.

Reese and Finch receive the number for Wallace Negel -- a mysterious man who hasn't had a single electronic transaction in his name since 1989. But as they dig for more details, they begin to suspect that Negel is not who he seems. Reese knows a cover identity when he sees one. This man is a spy. When bodies start to turn up, Reese and Finch need to figure out how they are connected to this agent and why he has returned to New York City after so much time. In this game of spy vs. spy, the old school operator matches his spycraft against Reese and Finch's neo-technology. We also learn more about Reese's early days in the CIA and his relationship to a mysterious woman named Stanton.

Reese and Finch's game of cat and mouse with Detective Carter becomes infinitely more complicated when The Machine declares that she is their newest POI.

­The machine gives Finch 4 numbers almost simultaneously, which means the POI's are probably connected. When they find the first number murdered, Reese enlists Finch and Fusco to help keep the others safe. Unfortunately Finch isn't able to get there in time for the second victim. Reese figures out that the remaining two numbers are foster sisters and manages to rescue them from an attempt on their life. Finch determines that all four seemingly unconnected people met at the scene of a car accident and they did something to make them targets.

Reese is confined to a wheelchair recovering from his gunshot wound, but Finch sets him up in an apartment where he's to keep an eye on the Super, who is their latest POI. Also, Finch approaches Carter and gives her a POI to show her what they do.

When Carter finally comes face-to-face with Reese, he urges her to join forces to help with their latest POI, a scrappy young woman from the wrong side of the tracks who turned her life around and became a lawyer.

­Reese and Finch's latest POI is a down-on-his-luck man who may have reached his breaking point. As the case evolves, the duo calls upon a former POI for help, the resourceful and well-connected Zoe.

The Machine identifies Darren, a teenager whose brother was just murdered, as the next POI. Meanwhile, Finch is growing concerned that the son of his former business partner is dangerously close to finding out about The Machine.

Reese infiltrates a group that specializes in couriering contraband in order to get close to their POI, the #2 in the operation. He's surprised to learn that his POI is an NYPD detective in deep cover.

The Machine leads Reese and Finch to Wall Street when a sharp young trader at a major investment bank becomes embroiled in a multi-million dollar financial scam.

When The Machine spits out the number of a 6-month-old baby, Reese and Finch turn into overly protective parents - with an arsenal at their disposal. Meanwhile, when Elias resurfaces, Detective Carter begins to question her new allegiance with Reese and Finch.

Finch and Reese are stymied to find their most recent POI is actually two different people. One is a beautiful woman who is an art dealer who is worried because she thinks someone is following her. The other is a man who was badly beaten and seems to be running an MDMA factory.

When The Machine spits out five numbers, naming the Don of each of New York's crime families, Reese and Finch suspect Elias is planning to eliminate his competition.

The Machine's latest mark puts Reese undercover as part of an armored truck crew, a case that brings back memories of his last CIA mission and painful decisions he was forced to make.

It's Reese's birthday, and Finch gifts him with a day off - especially when he realizes that The Machine's latest number is sure to revive painful memories.

The newest POI's curiosity could spell his doom when he finds himself embroiled in a dark government conspiracy - one that Finch is all too familiar with. Meanwhile, Reese uncovers something revealing about Finch's past.

When a psychologist's number comes up, Reese must protect her from one of her patients while eluding capture by the FBI, who are closing in fast. Meanwhile, Finch receives an unwelcome visit from an old acquaintance.
