The Yellowstone universe is expanding once more, and Kayce Dutton’s long-awaited spin-off, Y: The Marshal, has finally unveiled its first trailer and a premiere date of March 1, 2026, on CBS and Paramount+. Fans of Taylor Sheridan’s sprawling Dutton dynasty may not have clamored for a Kayce-led procedural – with its shift from ranch drama to law enforcement grit – but the sizzle reel promises a seamless fit for CBS’s Sunday night slot, blending the franchise’s moral ambiguity with high-stakes chases across Montana’s unforgiving landscapes.

“I fought every day to get out from under the weight of the Yellowstone,” Luke Grimes’ Kayce intones in the trailer’s opening voiceover, his weathered face etched with resolve. “I’ve lost my teammates, my parents, even my brothers. I know sometimes good men have to do bad things. But I’m trying to find a new beginning.” It’s a poignant evolution for the character, and with a stacked cast including Logan Marshall-Green, Arielle Kebbel, Ash Santos, Tatanka Means, and Brett Cullen – plus returning Yellowstone stalwarts Brecken Merrill, Gil Birmingham, and Mo Brings Plenty – Y: The Marshal looks poised to carve its own path in Sheridan’s ever-growing empire.

The trailer, dropped during CBS’s NFL doubleheader on Thanksgiving, clocks in at 2:15 and opens with sweeping drone shots of Montana’s snow-capped peaks and dusty badlands, Kayce’s voice narrating his transformation from Dutton heir to U.S. Marshal. Grimes, 45, reprises the role that made him a Sheridan staple since 2018, trading the Yellowstone brand for a weathered marshal’s badge as he joins an elite fugitive task force hunting high-value targets from cartels to domestic terrorists. “Kayce’s always been the moral compass,” Sheridan told Deadline at the TCA Winter Press Tour. “Now he’s enforcing it – but the line between justice and vengeance blurs fast in the West.” The footage teases pulse-pounding action: Kayce rappelling into a canyon for a midnight raid, exchanging gunfire with a fleeing suspect, and a tense standoff in a blizzard where he whispers to a cornered fugitive, “Sometimes good men do bad things – but this ends now.”

Joining Grimes is Logan Marshall-Green (Upgrade, Spider-Man: Homecoming) as Pete Calvin, Kayce’s grizzled partner with a shady vigilante past; Arielle Kebbel (John Tucker Must Die, Midnight in the Switchgrass) as Belle Harlan, the team’s sharp-shooting analyst with her own family secrets; Ash Santos (The Society) as rookie marshal Lena Torres, eager but green; Tatanka Means (Reservation Dogs) as tribal liaison Ray Two Feathers, bridging federal and indigenous jurisdictions; and Brett Cullen (Power) as grizzled Marshal Chief Harlan, Kayce’s reluctant mentor. Familiar faces from Yellowstone – Brecken Merrill as Tate Dutton (now a teen), Gil Birmingham as Chief Thomas Rainwater, and Mo Brings Plenty as Mo – weave continuity, with Tate’s cameo hinting at a Dutton legacy crossover.

Showrunner Spencer Hudnut (SEAL Team) crafts a procedural with Sheridan’s DNA: moral gray areas, family as anchor, and the West’s unforgiving beauty as backdrop. Filmed in Montana and Alberta, the series promises “cowboy code meets federal firepower,” per Hudnut. The trailer ends on Kayce’s steely gaze: “The weight never lifts – you just learn to carry it.”

Y: The Marshal premieres March 1 on CBS (9 p.m. ET) and streams on Paramount+ same-day. Not the Yellowstone fans clamored for, but Grimes’ return ensures Dutton’s spirit endures – badge and all.
