After Yellowstone premiered in June 2018, fans remained captivated by the gripping Western drama for more than six years. Created by Taylor Sheridan, the show is set in rugged Montana and explores the complex and often brutal world of ranching.

It's centered on John Dutton, the head of the largest contiguous cattle ranch in the United States, who's fighting to preserve his family's legacy. But along the way, the Duttons encounter relentless threats from encroaching land developers, a neighboring Native American reservation, and National Park authorities.

Yellowstone, which also tackled themes of family loyalty and power struggles, captured the hearts of viewers everywhere. That's why so many people were sad to learn that Season 5, which concluded in December 2024, marked the series' end.

Well, good news: there are apparently multiple spinoffs in the works right now, one of which will star Luke Grimes as he reprises the same role of Kayce Dutton, the youngest Dutton son.

Y: Marshals will follow Kayce after the events of Yellowstone season 5, and find him leaving the ranching life behind. Instead, he'll join a team of U.S. Marshals to protect the area. According to the official logline, Kayce's new line of work will combine "his skills as a cowboy and Navy SEAL to bring range justice to Montana, where he and his teammates must balance family, duty and the high psychological cost that comes with serving as the last line of defense in the region’s war on violence."

Who's in the cast?

You might be wondering whether his character Kayce's wife, Monica, or their son, Tate, will be part of the latest project. This would make sense, given how Yellowstone ended with Kayce selling the Dutton ranch back to Thomas Rainwater and the Broken Rock Indian Reservation, with intentions of his family residing on a piece of the property.

Unfortunately, whether Kelsey Asbille, who plays Monia, or Brecken Merrill, who portrays Tate, will be involved remains unconfirmed. Fans may just have to wait and see how this next chapter of the Yellowstone universe plays out. Stay tuned for the full cast list?

Are we getting a Yellowstone spinoff about Beth and Rip?
