Y: Marshals": Luke Grimes Returns to the Frontier in the Action-Packed Yellowstone Spinoff
The highly anticipated next chapter in the Yellowstone universe, Y: Marshals, is officially here, promising an action-packed, neo-Western take on justice in Montana. The series, a direct sequel and spin-off of the flagship show, sees Luke Grimes reprise his fan-favorite role as Kayce Dutton.
Y: Marshals is set to premiere on Sunday, March 1, 2026, at 8/7c on CBS, with episodes available to stream the next day on Paramount+.
The Premise: Range Justice in Montana
With the weight of the Yellowstone Ranch and his tumultuous family legacy behind him, Kayce Dutton leaves his former life to join an elite unit of the U.S. Marshals. The show's premise centers on Kayce using his unique blend of skills as a seasoned cowboy and former Navy SEAL to bring "range justice" to the rugged landscapes of Montana.
The official logline highlights the core conflict of the series: the team must balance duty, family life, and the "high psychological cost that comes with serving as the last line of defense in the region's war on violence".
The Cast: Returning Veterans and New Faces
Luke Grimes anchors the series, but he is joined by a blend of familiar faces from the original Yellowstone and new talent:
Luke Grimes as Kayce Dutton
Gil Birmingham as Thomas Rainwater
Mo Brings Plenty as Mo
Brecken Merrill as Tate Dutton
Logan Marshall-Green as Pete Calvin, an old military friend of Kayce's

Notably absent from the initial cast list is Kelsey Asbille (Monica Dutton), sparking fan speculation about her character's fate that the premiere episode is expected to clarify.
A New Beginning for the Dutton Universe
