After Yellowstone wrapped its epic run, fans thought they’d seen the last of the Duttons. But the franchise is far from over. Y: Marshals is about to open a bold new chapter in the Yellowstone universe—and this time, it’s all about Casey Dutton.

Played by the talented Luke Grimes, Casey is a character that has always been deeply grounded in conflict, honor, and the burdens of his family’s legacy. In Y: Marshals, Casey steps into the role of a U.S. Marshal, joining an elite group tasked with delivering what is called “range justice.” This series promises a thrilling mix of modern Western grit with the high stakes of law enforcement drama, set against the rugged Montana landscape.

While Yellowstone evolved into a sprawling political drama, Y: Marshals is taking things back to the roots of the Western genre. The story centers on personal battles, land disputes, and criminals trying to survive in a changing world. With 13 episodes already lined up for the first season, it’s clear the creators aren’t wasting any time diving into this new territory.

What makes this new series especially exciting is the opportunity to explore Casey’s transformation. After making the bold decision to sell the Yellowstone Ranch to the Broken Rock Tribe for just $1.25, Casey distanced himself from his family’s tumultuous legacy. This act wasn’t just financial—it was symbolic of his need for peace, and it left fans wondering what his future held.

As Y: Marshals picks up after the events of Yellowstone, the absence of Casey’s wife, Monica, and their son, Tate, raises intriguing questions. Will they be a part of this journey, or will Casey’s newfound role in law enforcement pull him even further away from his family? Fans can expect a deep dive into his inner conflict, as he struggles with the moral dilemmas that come with his new job, all while facing the ghosts of his past.

Spencer Hudnut, known for his work on SEAL Team, takes the reins as showrunner for Y: Marshals. While Taylor Sheridan remains as an executive producer, Hudnut’s experience with military storytelling will be pivotal in bringing Casey’s character to life, especially as a former Navy SEAL turned lawman. Expect Casey to grapple with his complex past as he tries to navigate the rules of justice in a modern Western world.

Filming for Y: Marshals is already underway in Utah, with the series set to premiere on CBS in the spring of 2026. The show’s promise of deep emotional storytelling, grounded in the Western tradition, is sure to captivate audiences. Casey Dutton’s journey from soldier to lawman, trying to balance personal integrity with the weight of justice, is shaping up to be one of the most compelling stories in the Yellowstone franchise.

With its rich premise and beloved character at the helm, Y: Marshals is gearing up to make waves. Stay tuned for more updates as the release date approaches—this new chapter in the Yellowstone universe is one you won’t want to miss!
