CBS Plans 'Y: Marshals' Yellowstone Spinoff Featuring Kayce Dutton's Marshal Career

The upcoming CBS spinoff "Y: Marshals" follows Luke Grimes's character Kayce Dutton as he leaves behind ranch life to join an elite unit of U.S. Marshals, combining his cowboy and Navy SEAL skills to deliver justice in Montana. The series will explore Kayce grappling with personal "skeletons" and the psychological toll of balancing family, duty, and his new law enforcement role, marking a significant shift from his previous arc in "Yellowstone." The show features a supporting cast including Arielle Kebbel, Ash Santos, Tatanka Means, Brett Cullen, and Logan Marshall Green, with Cullen playing the head of the Montana U.S. Marshals division. Grimes has expressed that this new role gives Kayce a clear sense of purpose and a fresh path, despite seeming to contradict his peaceful ending in the original series. "Y: Marshals" is set to premiere in 2026 as one of several "Yellowstone" spinoffs, promising a blend of cowboy grit and law enforcement drama. The series highlights themes of justice, family loyalty, and the costs of service in a violent region.
