Luke Grimes Returns as Kayce Dutton in First ‘Y: Marshals’ Trailer

CBS has just dropped the first trailer for ‘Y: Marshals,’ the newest spinoff in the expansive ‘Yellowstone’ universe. The series follows Luke Grimes as he reprises his fan-favorite role, Kayce Dutton, moving from the ranch to an elite unit of U.S. Marshals in Montana.

Plot and Tone
The trailer promises a procedural format that retains the franchise’s signature "range justice" aesthetic. Central to the story is Kayce’s internal battle to escape his family's history. Despite seeking a new beginning, he acknowledges the "weight of the Yellowstone," signaling that the drama remains deeply connected to the parent series' lore.

Cast Announcements
The show bridges the gap between generations and introduces new faces. Returning cast includes:

• Brecken Merrill as an older Tate Dutton
• Gil Birmingham as Thomas Rainwater
• Mo Brings Plenty as Mo

New ensemble members include Logan Marshall-Green (Pete Calvin), Arielle Kebbel (Belle Skinner), Ash Santos (Andrea Cruz), and Tatanka Means (Miles Kittle). Showrunners promise the show will balance high-stakes law enforcement with Kayce’s growth as a father.

Release Date
‘Y: Marshals’ is set to premiere Sunday, March 1, 2026, at 8 p.m. ET on CBS. Episodes will be available to stream immediately on Paramount+.
