Yellowstone Spinoff Marshals Hints At [Spoiler]'s Death In Full Trailer — Here's Everything We Know

"Yellowstone" giveth and "Yellowstone" taketh away. CBS has released the official trailer for its upcoming spinoff "Marshals," premiering March 1 (8 p.m. ET), and it seems to suggest that Kayce Dutton will suffer a massive personal loss before embarking on a new journey. Is Kayce's wife Monica really being killed off? Say it ain't so!

Set after the events of "Yellowstone," "Marshals" follows Kayce (Luke Grimes) as he leaves ranch life behind to join "an elite unit of U.S. Marshals, combining his skills as a cowboy and Navy SEAL to bring range justice to Montana, where he and his teammates must balance family, duty and the high psychological cost that comes with serving as the last line of defense in the region's war on violence," per the official logline.

And "Marshals" is just one of several "Yellowstone" projects on the horizon. Though not considered a direct spinoff, Taylor Sheridan's new Paramount+ series "The Madison" will follow a wealthy New York City family (led by Michelle Pfeiffer) that moves to rural Montana.

Other in-development spinoffs include "The Dutton Ranch," which will follow original "Yellowstone" characters Beth (Kelly Reilly), Rip (Cole Hauser) and Carter (Finn Little); "1944," another Dutton family prequel in the vein of "1883" and "1923"; and a new series set at Texas' Four Sixes ranch, which factored into the later seasons of "Yellowstone."

But let's get back to what we're here to discuss, "Marshals." Read on for a complete breakdown of everything we know about the "Yellowstone" spinoff, including which familiar faces you can expect to see again. When you're all caught up, drop a comment with your thoughts below. Will you ride on with Kayce?

"Marshals" officially premieres on Sunday, March 1 at 8/7c on CBS, right after "60 Minutes" (7 pm), the network revealed as part of its midseason schedule announcement. The "Yellowstone" spinoff will be followed by new episodes of Justin Hartley's "Tracker" (9 pm) and Morris Chestnut's "Watson" (10 pm).

Tate is the son of Kayce (Luke Grimes) and Monica (Kelsey Asbille), the latter of whom has not officially signed on to return for "Marshals." He appeared in all five seasons of "Yellowstone."

Always dressed to take care of business, Thomas is a man of many impressive titles. In addition to being a casino mogul, he was also elected high chief of the Confederated Tribes of Broken Rock. He also appeared in all five seasons of "Yellowstone."

What, you didn't think Thomas Rainwater would come back without his right hand man, did you? Along with being Thomas' driver, Mo is also a member of the Tribal Police. He also appeared in all five seasons of "Yellowstone."

Fresh off his turn as hunky gardener Adam Karma on HBO Max's "And Just Like That...," Marshall-Green will be playing Pete Calvin, one of Kayce's friends from his days in the military.

Most recently seen on Fox's "Rescue: HI-Surf," Kebbel will play a U.S. Marshal named Belle. Kebbel's previous TV credits also include Lucy Donato on ABC's "9-1-1," Tracy Legette on HBO's "Ballers," Olivia Charity on NBC's "Midnight, Texas," Lexi Branson on The CW's "The Vampire Diaries," and Lindsay Forester on The WB's "Gilmore Girls."

Last seen playing Nia Washington on Netflix's "Pulse," Santos will play a U.S. Marshal named Andrea. Santos' other previous TV credits include Coco on Paramount+'s "Mayor of Kingstown," Daphne on Netflix's "True Story" and Emily on FX's "American Horror Story: Apocalypse."

Means, last seen roaming the Texas Hill Country as Jake Longbow on Netflix's "Ransom Canyon" (pictured above), will play a U.S. Marshal named Miles. Additional TV credits include Sam on FX's "Reservation Dogs," Officer Edgar on Prime Video's "Outer Range" and Nabby Drinkwater on HBO's "I Know This Much Is True."

Cullen will recur as Harry Gifford, the head of the U.S. Marshals in Montana. Some of Cullen's recent TV credits include Samuel Kirkland on Netflix's "Ransom Canyon" (pictured above), Bill Sharman on HBO's "Winning Time: The Rise of the Lakers Dynasty," Ilya Koslov on NBC's "The Blacklist" and Gerald Kindt on HBO's "True Detective." He's perhaps best known for playing Dan Fixx on CBS' "Falcon Crest."

That's easily the biggest question facing "Yellowstone" fans at the moment. Though it hasn't been officially confirmed, the trailer certainly makes it look like Kayce's wife is not long for this world. In addition to seeing a doctor pull a white sheet over a body, we also see Kayce speaking with a woman from behind in what appears to be a flashback. Either way, all signs point to Kelsey Asbille not returning as Monica — at least not in the land of the living.
