When there’s a murder in New York City, it seems like a regular day for the New York Field Office. That couldn’t be further from the truth on the FBI season 8 fall finale.

Don’t forget that this is a two-hour fall finale, and both episodes are airing tonight, Monday, Dec. 15. This means twice the drama and twice the action, and we all know that we’re going to be on the edges of our seats. You will not want to miss this episode live.

What time are FBI season 8 episodes 9 and 10 on CBS?

The FBI season 8 fall finale starts a little earlier than we’re used to. You’ll need to tune in from 8 p.m. ET/PT on Monday, Dec. 15. It is a two-hour episode, so you’ll need to stick around until 10 p.m. ET/PT. You may as well stick with CBS all night as the Watson season 2 fall finale is also airing tonight straight after FBI.

You can catch FBI live in a few ways, as CBS wants to make it easy. That means through your regular cable provider, or via YouTube TV, Fubo TV, and other similar platforms if you’ve cut the cord.

Then there’s always Paramount+. There is a live viewing option for some subscriptions, but this is also the place the series goes to stream the day after. So, if you can’t tune in for the whole two hours tonight, then you can tune in from 3 a.m. ET/12 a.m. PT on Tuesday, Dec. 16.

At first, it seems like it’s a lone wolf looking to get some sort of revenge, but things change as there is an attack on Lower Manhattan. This is more than one person attacking a few people. A group of radicalized people want to reset society, and that means taking out everything that keeps society organized and calm. With cell phones and internet disrupted, the whole city is thrown into chaos, and it’s made even worse when emergency services are also attacked.

Chaos erupts in the city when an attack disrupts cell, internet and emergency services. As the team races to uncover the culprits, they learn the group responsible is a radical accelerationist movement fixated on resetting society.

The New York Field Office will need to remain calm and do everything they can to protect the city that is their home.

FBI will return on Monday, Feb. 23 at 9/8c on CBS after this episode tonight.
