“You’re not a killer… You’re a protector.” But look at his eyes… he’s lost EVERYTHING. Kayce Dutton (Luke Grimes) walks away from the Yellowstone forever, straps on the U.S. Marshals badge, and dives into Montana’s bloodiest war on crime. Gunfights on horseback. Helicopter chases. A son he’s fighting to protect… but where the hell is Monica?!?

Fans are already screaming: Did she DIE? Is this Kayce’s dark redemption or total destruction? This is NOT the cowboy you knew – this is pure vengeance. Click before CBS takes it down! Premieres March 1 – you ready?!

The long-awaited first full trailer for the Yellowstone spinoff Marshals has finally arrived, offering viewers a gripping look at Luke Grimes reprising his role as Kayce Dutton in a stark departure from the ranch life that defined the original series.

Set to premiere Sunday, March 1, 2026, at 8/7c on CBS—with episodes also streaming on Paramount+—Marshals (formerly marketed as Y: Marshals) marks the franchise’s first direct sequel following the conclusion of Yellowstone in late 2024. Created under the banner of Taylor Sheridan, the series shifts the focus from family land wars to modern law enforcement, as Kayce joins an elite U.S. Marshals unit tasked with bringing justice to Montana’s violent frontier.

The trailer, released in late November 2025 and recently followed by additional teasers, opens with a haunted Kayce reflecting on profound loss. “I fought every day to get out from under the weight of the Yellowstone,” he says in voiceover. “I’ve lost my teammates, my parents, even my brothers.” The line sets a somber tone, emphasizing personal tragedy over the sweeping ranch battles fans remember. Thomas Rainwater (Gil Birmingham) appears to counsel him: “You’re not a killer, Kayce. You’re a protector.” Yet the footage quickly pivots to high-stakes action—horseback pursuits through snow-covered terrain, tactical raids, and intense shootouts that blend Western grit with contemporary procedural drama.

Kayce’s transition to U.S. Marshal feels organic given his backstory: a former Navy SEAL with deep ties to both cowboy culture and the Broken Rock Reservation. Official synopses describe him combining those skills to deliver “range justice” while grappling with the “high psychological cost” of the job. His team includes Pete Calvin (Logan Marshall-Green), Belle Skinner (Arielle Kebbel), Andrea Cruz (Ash Santos), and Miles Kittle (Tatanka Means). Returning Yellowstone characters like Tate Dutton (Brecken Merrill), Thomas Rainwater, and Mo Brings Plenty (Mo) provide continuity, with Tate remaining a central emotional anchor for Kayce.

One glaring absence has ignited fan speculation: Monica Dutton (Kelsey Asbille), Kayce’s wife, is nowhere to be seen in the trailer or any promotional materials. Reports and online discussions point to possible tragedy or separation, with some interpreting Kayce’s weary demeanor and father-son emphasis as signs of widowhood or estrangement. CBS and Paramount have offered no confirmation, leaving the mystery intact ahead of the premiere. Show insiders have described Kayce as “a changed man,” fueling theories that personal devastation propels him into this new role.

The series arrives as CBS repositions its Sunday night lineup, slotting Marshals at 8 p.m. ET followed by Tracker. This broadcast debut broadens the Yellowstone audience beyond Paramount+ streaming, capitalizing on the original show’s massive ratings history. Executive produced by Sheridan alongside key collaborators, Marshals maintains the franchise’s signature blend of moral complexity, family loyalty, and unflinching violence.

Grimes has been a fan favorite since Yellowstone‘s 2018 debut, evolving Kayce from a wayward veteran to a pivotal Dutton defender. His military experience and spiritual connections added nuance, making the Marshal pivot a natural evolution. The trailer showcases him in tactical gear yet still on horseback, symbolizing the fusion of old West and new frontier law enforcement.

Supporting performances promise depth: Marshall-Green brings intensity as Pete Calvin, while Means adds cultural layers as Miles Kittle. The ensemble appears tested by both external threats and internal tolls, with the logline highlighting the balance between duty and family life.

Fan reaction has been electric since the trailer’s drop. Social media clips highlight rapid-fire edits of chases and confrontations, drawing comparisons to modern action thrillers while retaining Sheridan’s Western roots. Many praise the psychological edge, speculating on Kayce confronting unresolved trauma from ranch conflicts.

As March approaches, Marshals positions itself as a bridge between Yellowstone‘s legacy and fresh storytelling. Whether Kayce finds redemption or succumbs to darkness remains the core intrigue. For now, the trailer delivers exactly what fans crave: high-octane drama, emotional stakes, and the promise of more Dutton saga twists.

With production wrapped in locations like Park City, Utah, and Montana’s landscapes providing authentic backdrops, expectations are sky-high. CBS’s decision to air it network-wide signals confidence in its draw, especially following Yellowstone‘s cultural impact.

The March 1 launch will answer lingering questions—about Monica, about Kayce’s psyche, and about whether this new badge can shield him from his past. Until then, the trailer stands as a potent teaser: Kayce Dutton isn’t done fighting. He’s just changed the battlefield.
