Luke Grimes is officially stepping back into the boots of Kayce Dutton—but this time, the road ahead looks darker, deeper, and far more dangerous. The highly anticipated Yellowstone spinoff, Y: Marshals, is giving fans their first real glimpse at what’s next for the fan-favorite character—and it’s clear Kayce is fighting more than just criminals.
In a new teaser, Kayce joins a new team of U.S. Marshals, admitting to his fellow recruits, “I’m just grappling with some skeletons I’d like to keep in my closet.” And for longtime Yellowstone viewers, that statement says everything.
Kayce Dutton Starts Over — But a New Beginning Comes at a Cost
Kayce Leaves Ranch Life Behind
According to the official series synopsis, Y: Marshals follows Kayce as he steps away from ranching and enters a high-intensity U.S. Marshals unit in Montana. The job lets him merge two identities fans know well:
- His cowboy upbringing
- His experience as a Navy SEAL
Now, he’s bringing “range justice” to a region fighting escalating violence—while balancing family, duty, and the emotional toll of being the last line of defense.
A Shift Fans Didn’t Expect
In another promo clip, Kayce says, “I’m changing paths. Trying to find a new beginning.”
This is a major shift from the life he built at the Yellowstone Ranch, and it hints that the spinoff will heavily explore Kayce’s internal battles as much as the external ones.
Meet the Cast of Y: Marshals
The series introduces a new lineup of characters alongside Kayce, blending familiar energy with fresh faces.
Main Cast:
- Luke Grimes as Kayce Dutton
- Arielle Kebbel as Belle
- Ash Santos as Andrea
- Tatanka Means as Miles
- Brett Cullen as Harry Gifford, head of the Montana U.S. Marshals

The mix of personalities and backgrounds is set to give the series a new dynamic that stands apart from Yellowstone while still honoring its roots.
Luke Grimes on Returning to Kayce: “It Was Emotional”
When Yellowstone wrapped in 2024, Grimes thought he had said goodbye to Kayce forever.
He admitted that the final day of filming felt like closing a major chapter of his life—one that left him more emotional than expected.
“It was sort of like losing a family,” he reflected in an interview.
Months later, when the idea for the spinoff came together, Grimes was surprised—and excited. But he made one thing clear: the story needed real depth.
“If it was just him being happy, that’s not very cool,” Grimes said. “The idea they pitched was so interesting, it hooked me immediately.”
