It's the beginning of the end for Person of Interest.

IGN has the exclusive debut of the new extended trailer for Season 5, the final season of CBS's action drama starring Jim Caviezel, Kevin Chapman, Sarah Shahi, Amy Acker and Michael Emerson. Watch it below:

There's plenty to be excited about in this two-minute preview, but it's especially exciting to see just how much Shaw is in it. As Sarah Shahi promised at Person of Interest's New York Comic Con panel, "Shaw comes back in a very dynamic way."

The trailer leans into how this is the final season, but also plays up that there's plenty of excitement, gunfights and apocalyptic situations in our future. Oh, also, apparently some romance for a certain fan-favorite pairing?

"We’re extremely excited to be able share this final season with the fans. We’re eternally grateful to our amazing cast and crew, as well as our partners at the studio and network," said showrunners Jonathan Nolan and Greg Plageman when they announced Season 5 would be PoI's final season.

"Most of all, we want to thank the show's fans — the best fans in the world. This subversive little paranoia-inducing cyberpunk-thriller is for you and would not have been possible without your support. As life has come to imitate Person of Interest, it’s been our great privilege to work on show for the past five seasons. We can’t wait for you to experience this thrilling and final chapter."

Neither can we.

Person of Interest: Season 5 premieres Tuesday, May 3 at 10 p.m. ET/PT on CBS.

Own comment: Season 5 looks AWESOME. Too bad they decided not to continue with POI. Fantastic series. Let's hope for a satisfying finale.
