Yellowstone Spinoff 'Marshals' Premieres with Major Reveal

The new CBS series follows Kayce Dutton as he joins a team of U.S. Marshals, but it comes with a surprising twist about his wife Monica.

Published on Mar. 2, 2026

The first Yellowstone spinoff series, Marshals, has premiered on CBS and Paramount+, following the character of Kayce Dutton (Luke Grimes) as he joins a team of U.S. Marshals after being recruited by an old Navy friend. While the show is a classic procedural, it comes with a major reveal - Kayce's wife Monica, a fan-favorite character from the original series, has died off-screen from an illness.

Why it matters

The death of Monica Dutton, played by Kelsey Asbille, is a surprising and controversial move, as she was a central figure in Yellowstone and her relationship with Kayce was a major storyline. Her demise is seen by some fans as an abrupt and unsatisfying end to the character, while others who disliked her may welcome Kayce's newfound freedom. The spinoff also marks a shift in tone from the family drama of Yellowstone to a more straightforward procedural format.

The details

In the first episode of Marshals, we learn that Monica has passed away from an illness, leaving Kayce a widower. Her death is referenced when Kayce's son Tate is seen holding up a photo of her at a rally against a mine that the local Broken Rock reservation believes will poison their water supply. Kayce is now part of a diverse team of U.S. Marshals, including his old Navy friend Pete, a former undercover ATF agent, a former tribal cop, and a former Bronx cop. This team tackles various law enforcement cases in Montana.

  • Marshals premiered on CBS this weekend (March 2, 2026) and streams on Paramount+ the following day.
