I love Yellowstone, I always have, I always will. However, I’ve also had a long-standing problem with the show and its treatment of Luke Grimes’ character, Kayce Dutton. Thankfully, Kayce will return for his own CBS spinoff in the spring of 2026, which means there’s a new chance to rectify my biggest issue with Yellowstone.
We Know Kayce’s Yellowstone Show Will Combine His Past In The Military With Life On The Ranch
Alongside a slew of upcoming Yellowstone shows – including a spinoff about Rip and Beth – CBS announced its 2025-2026 lineup will include a series tentatively called Y: Marshals. It will follow Kayce, the youngest of the Dutton siblings, as he figures out life after the events of Yellowstone.
According to CBS’s announcement, the series will focus mostly on Luke Grimes’ character’s new job with the U.S. Marshals. The synopsis explained:
Y: MARSHALS (working title) stars Luke Grimes as Kayce Dutton. With the Yellowstone Ranch behind him, Dutton joins 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.
So, it sounds like worlds will collide, as the youngest Dutton uses his military skills and his past on the ranch to seek justice in Montana. That alone is a premise that has me sold. However, the notion that this series will finally address an element of Kayce’s story that’s been severely overlooked has me even more excited.
Paramount Plus: from $7.99 a month/$79.99 a year
Almost all the Yellowstone shows are available with a Paramount+ subscription alongside other originals from the streamer and CBS’s lineup. So, it’s well worth the $7.99 per month. You can also upgrade to Premium and pay $12.99 per month to add Showtime and take away ads. View Deal
Hopefully, This Finally Means We’ll Get To Learn More About Kayce’s Past In The Military
Now, when I watched 1923, I wrote about how that show fixed my Kayce problem. In the prequel, we got to see Spencer travel the world after life in the military, hone in on his destiny as the Dutton successor, and be the hero of the series. I thought all that would happen with Luke Grimes’ cowboy in the OG show too, and it didn’t.
How To Watch The Yellowstone Shows

To see how Kayce’s story started, you can stream Yellowstone with a Peacock subscription. Eventually, you’ll get to see his tale continue on CBS. To watch every other series and story within the Yellowstone universe, you need a Paramount+ subscription.
However, now, he has the opportunity to explore facets of his character that he never got to in Yellowstone. This includes his past in the military, which is an aspect of Kayce that I’ve always wanted to learn more about.
From the jump on Yellowstone, it was clear that there was so much interesting backstory to mine with Kayce, especially when it came to how he used that past to inform his present on the ranch. However, it never happened. We got glimpses of his history in the military; however, never any full flashbacks of his time as a Navy SEAL. Plus, we only got to see him deploy his skills on a few occasions.
With Y: Marshals, we’ll get to solely focus on Kayce and seemingly this aspect of his story that I was dying to get more of back when Yellowstone was on.
So, yeah, I’m stoked about this new Yellowstone spinoff, and I cannot wait to see how Luke Grimes continues to play this Dutton character that deserved so much more than he got on the flagship show.
