'Person Of Interest' Season 4 Spoilers: Will Jim Caviezel, Michael Emerson Discover "Point Of Origin?" [WATCH]

Season 4 of Person of Interest continues with an all-new action-packed episode on CBS. Not only does Team Machine's new number may need protection, Reese (Jim Caviezel), and Finch (Michael Emerson) might also find themselves in danger they cannot escape from in 'Point of Origin.'

As we previously mentioned, The Machine was beaten by a much more powerful Artificial Intelligence, known as Samaritan. To stay far away from Samaritan's growing radar, Finch (Emerson) and his group assumed normal, regular lives to prevent themselves from getting caught. The stakes are even higher now as the Samaritan is growing an army and a new rival mob boss is taking over the streets.

According to the official IMDB page, Reese (Caviezel) finds himself volunteering as an NYPD police academy instructor, so that he can keep an eye on a talented young officer, who may also be a threat to his cover. Meanwhile, Martine (Cara Buono), the blonde-haired assassin that Root (Amy Acker) had a shootout with, now has information from Samaritan she can use to Team Machine.

In the footage, we also see that Dr. Iris Campbell (Wrenn Schmidt) makes a reappearance after Prophets. Finch's military dog, Bear, also seems to be involved in an action sequence as well.

Check out this preview of Point of Origin here:

We previously mentioned, in Honor Among Thieves, Shaw (Sarah Shahi)'s cover was suddenly compromised when Crimson 6 arrived .The operatives Devon (Nick Tarabay) and Brooks (Theodora Woolley) were once trained by Shaw herself and are now working for Samaritan. Brooks attempted to delete the video but the footage was recovered by Samaritan, who is slowly reconstructing Shaw's facial recognition.

Shahi reveals, "The stakes are going to be so high and it's going to get yucky and nasty and it's going to happen fast."
