Kayce Dutton Spinoff Trailer Reveals First Look at Luke Grimes’ Y: Marshals

Yellowstone’s Quiet Hero Rides Again

The Yellowstone saga continues to grow — and this time, it’s Luke Grimes’ turn to take center stage. CBS has dropped the first official trailer for Y: Marshals, the long-rumored Yellowstone spinoff following Kayce Dutton as he trades the family ranch for the high-stakes world of U.S. law enforcement.

Set to debut sometime in 2026 (exact release date still under wraps), the action-packed preview teases a darker, grittier take on the franchise, one that leans heavily into crime drama territory while staying true to Yellowstone’s signature mix of rugged landscapes, moral conflict, and family legacy.Yellowstone Spinoff Y Marshals CONFIRMED — Kayce Dutton Returns! - YouTube


🔥 The Story: From Ranch Hand to Lawman

Following the fallout of Yellowstone Season 5, Y: Marshals finds Kayce Dutton leaving behind the Yellowstone Ranch to join an elite U.S. Marshals task force in Montana. Drawing on his military experience and cowboy instincts, Kayce becomes part of a team dedicated to delivering “range justice” — where the lines between right and wrong blur with every case.

The series will explore Kayce’s struggle to balance duty and family, particularly the toll that his new life takes on his marriage and his young son, Tate (Brecken Merrill). The trailer hints at emotional moments intertwined with explosive action, gunfights, and a sense of moral reckoning that defines the Dutton legacy.

“He’s not just chasing criminals,” Grimes told Entertainment Tonight. “He’s chasing redemption.”

Behind the scenes, the series brings together Yellowstone’s top creative forces. Franchise creator Taylor Sheridan serves as executive producer alongside David C. Glasser, John Linson, and Luke Grimes himself. The showrunner is Spencer Hudnut, best known for his work on CBS’s SEAL Team — fitting, given the military-infused tone of this new chapter.


🚨 What Fans Can Expect

The trailer promises a blend of Western grit and modern procedural tension, positioning Y: Marshals as both a standalone drama and a continuation of Kayce’s emotional arc. Fans can expect sweeping Montana scenery, heart-pounding action sequences, and introspective moments that test Kayce’s soul.

“It feels like Yellowstone meets SEAL Team,” said one insider. “Kayce’s fighting battles out in the open now — but the ghosts from the ranch still follow him.”

With Yellowstone’s main series approaching its conclusion and spinoffs like 1944 and The Madison expanding the universe, Y: Marshals is set to bring a new kind of frontier justice to TV screens.
