Season 4 of Person of Interest will find the show's main characters trying to figure out how to hide from the increasingly powerful Machine.

Person of Interest executive producers Jonathan Nolan and Greg Plageman spoke with Zap2It recently and revealed what was ahead for Season 4 this fall. With the Season 3 finale essentially wiping the slate clean on the show's premise (Library destroyed, Finch, Reese, Shaw and Root assuming new identities), Season 4 will be about the aftermath.

"Next year will be figuring out how are these guys going to hide from this almost omniscient entity that can track them," Plageman said. "But more importantly, what is Harold Finch going to do now that he clearly expressed his ambivalence on the stand about the Machine he created? Given that the Machine told him to kill the congressman last year and he stepped away, what happens now when there's an even more powerful artificial intelligence out there that's tracking them that's predatory? The relevant numbers are now Samaritan's job. This is the deal that Greer struck with the government, with Control. Now the question is what happens with the irrelevant numbers."

Plageman and Nolan suggested that it had been the plan to essentially blow up the show for a long time. Plageman said that the series had been building to the events of the season 3 finale.

"Headed out of it, we know exactly where we're going. There will be some fun surprises along the way. But one of the things that we were most excited about three seasons in is we had these superhero-like figures, but for Reese and Shaw and Root and Finch, their lives have been somewhat simple until this point because they just get to do the cool part. They just get to be the heroes."

Person of Interest Season 4 premieres in fall 2014 on CBS, though the specific premiere date has not yet been announced. It will return to its Tuesdays at 10 p.m. timeslot.

As the press release for the new CBS schedule noted, the move to Tuesdays at 10 p.m. "increased the time period by nearly +30% in key demographics this season, contributing to a consistently dominant night."
