Uncovering Y: The Last Marshal: What We Know About the Yellowstone Spin-Off Starring Luke Grimes as Kayce Dutton. More Revelations Than You .Might Expect
The CBS series is poised to pick up right where the original Yellowstone left off, venturing into uncharted territory for a Taylor Sheridan production. From fresh plot developments and casting announcements to other intriguing updates, let’s explore what’s ahead for this exciting new chapter in the Yellowstone franchise.
Y Marshals marks a bold shift, embracing a procedural format that promises episodic storytelling unlike anything in Sheridan’s rugged ranch saga.
The upcoming CBS series will resume directly from Yellowstone’s conclusion, steering into bold new ground never before explored in a Taylor Sheridan creation. With emerging plot details, casting reveals, and additional developments, here’s a deep dive into what awaits in this thrilling expansion of the Yellowstone universe.
Y Marshals represents a daring departure, adopting a procedural structure that delivers case-of-the-week narratives—far removed from the sweeping, serialized drama of Sheridan’s iconic ranch epic.
Understanding the Procedural Format
Though “procedural” may sound unfamiliar to casual viewers, it defines a cornerstone of network television. These series center on law enforcement or military agencies tackling crimes episode by episode, inviting audiences to solve mysteries alongside the investigators.
Classic Examples of the Genre
Iconic procedurals include Law & Order, NCIS, CSI, and countless acronym-branded hits. Each delivers self-contained cases wrapped in character-driven drama, a formula proven to captivate millions weekly.
Y Marshals: Kayce’s New Frontier
In this Yellowstone spin-off, Y Marshals follows Kayce Dutton—John Dutton’s youngest son—as he joins an elite U.S. Marshals unit. Per the official logline, Kayce blends his cowboy roots and Navy SEAL training to deliver “range justice” across Montana, balancing family, duty, and the mental toll of being the region’s final bulwark against violence.
A Network Home on CBS
Unlike its Paramount Network predecessor, Y Marshals will air on CBS, bringing Sheridan’s gritty Western world to broadcast television’s broader audience with a case-driven, episodic structure.
Rumors Confirmed and Context Established
Whispers of a Marshals-focused series have circulated for months, even surfacing in earlier discussions of the Beth-and-Rip spin-off. Now solidified, Y Marshals emerges as a bold evolution of the Yellowstone universe.
The biggest departure for Y Marshals is its status as the first Taylor Sheridan Yellowstone franchise entry created specifically for network television.
While Yellowstone itself was later edited and rebroadcast on CBS after premiering on Paramount Network, Y Marshals is being crafted from the ground up to meet CBS broadcast standards—ensuring a tone, style, and content level distinct from the franchise’s cable counterparts.
Taylor Sheridan Steps Back from Showrunner Duties
Taylor Sheridan will not serve as the showrunner for Y Marshals. With an extensive slate of active projects—including The Madison, the next Yellowstone origin series, Tulsa King, Mayor of Kingstown, Lioness, and several others—Sheridan simply lacks the bandwidth to oversee day-to-day operations on another series.
Spencer Hudnut Takes the Helm
Stepping in as showrunner is Spencer Hudnut, a veteran of procedural television best known for his work on SEAL Team. Hudnut’s experience with high-stakes, character-driven episodic storytelling makes him a natural fit to lead Y: Marshals through its law enforcement-focused narrative.
Sheridan Remains Involved as Executive Producer
Though not running the show, Taylor Sheridan will stay deeply connected as an executive producer, joined by John Linson, Art Linson, Ron Burkle, David Hutkin, and Bob Yari. Additionally, series star Luke Grimes will receive an executive producer credit, ensuring the actor’s insight into Kayce Dutton shapes the series’ direction.
The Yellowstone finale may have set up this spin-off.
In the Yellowstone series finale, Kayce Dutton sold the vast Dutton Ranch back to Thomas Rainwater (Gil Birmingham) at the original 19th-century price of $1.25 per acre, while securing a modest parcel for his family to remain on the land.
The concluding episodes also showcased Kayce leveraging his military contacts to neutralize his brother Jamie and safeguard the Dutton legacy. These flashes of tactical prowess hint at his readiness for the high-stakes investigations in Y Marshals.
However, Kayce’s longstanding reluctance to hold any official position during Yellowstone raises intriguing questions about what ultimately compels him to join the U.S. Marshals—leaving a compelling mystery for the spin-off to unravel.
Which Yellowstone characters will appear?
It is virtually certain that Y Marshals will feature Kelsey Asbille reprising her role as Kayce’s wife, Monica, alongside Brecken Merrill as their son, Tate. As the family resides on the small parcel retained from the Dutton Ranch, their presence anchors the series’ emotional core.
Given that Kayce and his family remain on a portion of the original Yellowstone property, Gil Birmingham is likely to return as Thomas Rainwater, along with other Yellowstone characters who stayed in Montana after the flagship series concluded.
Crossover opportunities abound, and it would be unwise to dismiss the potential for CBS and Paramount to orchestrate reunions between Kayce and his sister Beth (Kelly Reilly) or the ever-loyal Rip Wheeler (Cole Hauser).
Such crossovers could not only boost viewership but also deepen the emotional stakes, allowing Y Marshals to bridge the procedural format with the raw family drama that defined Yellowstone.
Given the stark tonal differences between Yellowstone’s raw, serialized intensity and Y Marshals’ episodic procedural style, crossovers may be rare or carefully calibrated. Still, failing to explore even occasional reunions with key characters would squander a powerful draw for fans.
Production is scheduled to kick off in Summer 2025, armed with a blockbuster budget that surpasses most network television fare. However, the series will inevitably be tempered to meet CBS broadcast standards—dialing back the nudity, graphic violence, and profanity that define premium cable and streaming counterparts.
CBS has officially slotted Y Marshals for a Sunday night premiere at 9 p.m. EST, with a 13-episode first season set to launch in Spring 2026. As production ramps up, expect casting announcements and detailed plot reveals in the coming months.
