Person of Interest season three ended with one hell of a cliffhanger: the whole country plunged into an Orwellian dystopia by a ruthless artificial intelligence. Where can we possibly go from there? Check out an exclusive clip from tomorrow night's season opener which shows how dark things can get.

Here's the official synopsis for tomorrow night's premiere, fittingly called "Panopticon":

THE TEAM MUST DEVISE NEW WAYS TO CONTINUE THEIR WORK WITHOUT BEING DETECTED BY SAMARITAN AFTER THEY'RE FORCED TO TAKE ON NEW IDENTITIES, ON THE FOURTH SEASON PREMIERE OF "PERSON OF INTEREST," TUESDAY, SEPT. 23

"Panopticon" – Forced to take on new identities created by Root, the team tries to adapt to their new lives. However, some find it hard to ignore The Machine's numbers, which puts them all at risk of being detected by Samaritan, on the fourth season premiere of PERSON OF INTEREST.

Person of Interest airs at 10 PM tomorrow evening on CBS.
