'Person Of Interest' Season 4 Recap: Jim Caviezel's Reese, Michael Emerson's Finch Search For Shaw In "Control-Alt-Delete!"

Season 4 of Person of Interest delivers the third part of its epic and action-packed trilogy on CBS. With Shaw (Sarah Shahi) missing, Reese (Jim Caviezel) and Finch (Michael Emerson) will go through Samaritan and its agents to get her back in 'Control-Alt-Delete.'

While trying to get Shaw back, Root (Amy Acker) and Reese are wearing ski masks as they shoot their way through the city. Fusco (Kevin Chapman) covers for them as the news media shoves their cameras unto their face. After dropping off her daughter at school, Control (Camryn Manheim) has to go to work in Washington.

The creepy kid, the avatar of Samaritan, is back, claiming responsibility for the stock crash to the White House Chief of Staff. The Chief of Staff thinks the whole thing is a joke, but the creepy kid promises to return when his stock portfolio is down 16 percent. Elsewhere, Control is hunting down four terrorists in Detroit.

After Crimson Six takes down three of the terrorists, the fourth one manages to escape. Unfortunately, Samaritan will not unlock what's inside his laptop. When Control starts to demand access, Samaritan shuts itself down. 

The quarantined laptop contains a nuclear virus that could possibly hurt Samaritan. Control has no choice but to accept Samaritan's demands. While the manhunt for the terrorist continues, Control orders Crimson Six to get their hands on the laptop. 

While the terrorist, Sayid, escapes, Crimson Six grabs the laptop from him. Unfortunately, the laptop burns itself out and Control gets a text from Samaritan, warning her, "Stop It Now." The manhunt for Sayid takes Control to a railroad station. 

As Sayid manages to get on the train to Canada, Root and Reese ambush Control with a rocket launcher. After her black van flips over, Control crawls out bruised and bleeding. Root and Reese take Control to their hideout. 

Tied up to a chair, Control is interrogated by Reese, who wants to know where Shaw is. Control wouldn't know where Shaw, nor would she care, because there's a terrorist on the loose. After Reese is done grilling her, Root tortures Control with electrocution. 

After Finch puts a stop to Root's torture, Control starts the homing beacon on her watch. Though Reese and Root want to believe Shaw is still alive, Finch believes she is dead. Nonetheless, Finch knows Shaw died saving them and he intends to honor that.

As Team Machine fights Crimson Six, Finch explains to Control there is a mole in her organization. Samaritan is the cause of the stock exchange taking a nosedive. To make matters worse, Samaritan has even hired a private army to stalk Control. 

Fusco takes out the surveillance team, which allows Finch to find the mole and plant a worm to follow the cell signal. Finally, Control manages to find Sayid in Canada, who confesses he was setup. Because Control doesn't want to believe Samaritan has been lying to her, she shoots him down. 

Hoping to find Shaw, Finch sends Reese and Root to the coordinates his worm found. The creepy kid returns to meet Chief of Staff and this time, he wants his next visit to be with the President. 

Control revisits the crime scene and discovers fresh white paint on the wall. Finch was right; Samaritan is trying to cover up its tracks.

Samaritan has Shaw's missing body hiding somewhere in Person of Interest. Readers, what did you think of Control-Alt-Delete?
