The Machine is self-governing. Its whereabouts are unknown. And a bevy of handsome naval officers are coming to down.

That's how CBS teases the Person of Interest Season 3 premiere, which airs on Tuesday, September 24 and which will include a new, lesser role for Carter.

What else can fans expect from the return of this enjoyable drama? Read on for the network's official synopsis of "Liberty."

The Machine, now completely self-governed with its whereabouts unknown, resumes giving Finch its “irrelevant” numbers for people in danger, which include a U.S. naval officer in town for Fleet Week. However, with so many sailors flooding the streets of New York City, finding the officer in time presents an even bigger challenge for Reese and Shaw. Meanwhile, Carter has been demoted to a patrol officer as a result of her being set up by the corrupt police crime organization HR, and sets a plan in motion to eradicate them for good. Also, Root tests the boundaries of her new asylum surroundings.
