'Person Of Interest' Season 4: Ep 19 Spoilers: Will Jim Caviezel's Reese 'Search & Destroy' Samaritan! [WATCH]

Back from hiatus, CBS will air an all-new episode of Season 4 of Person of Interest. With Team Machine dwindling in numbers, will Finch (Michael Emerson) and Reese (Jim Caviezel) be have to 'Search and Destroy' the all-powerful Samaritan before things get worse for them?

As we previously mentioned, the fourth season started with Team Machine on the run. With new identities, the group had to lay low or else they would be detected by Samaritan's radar. But all things changed during the recent trilogy, which left Shaw (Sarah Shahi) taken prisoner by the mysterious Greer. Samaritan even sent in its avatar to deliver a message to the President of the United States.

In our recent recap, Reese found himself chasing after bounty hunter Frankie Wells (Kathryn Winnick). Finch though had to stop Root (Amy Acker) from killing Elizabeth Bridges, a woman Samaritan had been keeping tabs on. Though Finch drank the poison to prevent Root from becoming a murderer, she ruined Elizabeth's career in the aftermath. While Finch found himself unable to talk to Root, Iris (Wrenn Schmidt) professed her love towards Reese.

As we mentioned before, Aasif Mandvi guest stars on tonight's episode. The Daily Show correspondent will be playing a "bright but demanding tech tycoon" who really "has a knack for making enemies."

According to TV Equals, Reese and Finch scramble to protect their latest POI, a software CEO (Mandvi). When the CEO's behavior becomes increasingly erratic after a hacker attack reveals all his secrets and unravels his life. From the footage, it looks like Finch and Root have to bury the hatchet if they want to team-up and take the fight to Greer.
