The Yellowstone universe is expanding again, and this time the spotlight returns to one of the franchise’s most complex characters — Kayce Dutton. Paramount has revealed the first extended look at Y: Marshals, the highly anticipated spinoff centered on the tortured son of the Dutton family. With new dangers, emotional struggles, and a powerful new storyline, the series promises to deliver the same gritty drama fans love.
A Fresh Start That Isn’t So Simple
At the end of Yellowstone, Kayce tried to leave behind the violence and trauma of the ranch. But the trailer for Y: Marshals shows that peace won’t come easily.
Kayce says, “I fought every day to get out from under the weight of the Yellowstone… I’m trying to find a new beginning.”
Yet his “new beginning” pulls him back into conflict as he joins an elite team of U.S. Marshals in Montana.
Who’s Returning?
Several familiar Yellowstone faces are back:
- Luke Grimes as Kayce Dutton
- Brecken Merrill as Tate Dutton
- Gil Birmingham as Thomas Rainwater
- Mo Brings Plenty as Mo
Who’s Missing?
Notably absent from the cast list is Kelsey Asbille, who played Monica Dutton. Her absence raises major questions about Kayce’s family storyline — and fans are already speculating whether tragedy has struck again.
Kayce Dutton’s New Mission
In Y: Marshals, Kayce applies his background as a cowboy and Navy SEAL to track criminals and bring justice to Montana’s vast and violent landscape.
The New Marshal Team
Kayce works alongside four new teammates:
- Pete Calvin – Logan Marshall-Green
- Belle Skinner – Arielle Kebbel
- Andrea Cruz – Ash Santos
- Miles Kittle – Tatanka Means
Their job: serve as the last line of defense in a region overwhelmed by rising crime.
The series highlights the toll this high-risk work takes — mentally, emotionally, and physically — especially for Kayce, who is already carrying years of trauma.
Family, Loyalty, and Inner Demons
One of the core storylines is Kayce’s attempt to balance his dangerous job with his responsibilities as a father. Tate is now older and joins him in uniform, suggesting the father–son dynamic will play an even bigger role.
Kayce also maintains close ties with Rainwater and Mo from the Broken Rock Reservation, keeping his long-standing alliances alive.
Official Logline (Simplified)
After leaving the Yellowstone Ranch, Kayce Dutton joins a top-tier U.S. Marshals unit. But as he fights to bring justice to Montana, he must also protect his family and confront the psychological cost of his violent past.
