Yellowstone’s Luke Grimes trades cattle for criminals in Taylor Sheridan’s gritty CBS spin-off

A New Beginning for a Broken Dutton

Kayce Dutton isn’t done yet.

After the seismic finale of Yellowstone, where the Dutton family fractured for good, Luke Grimes’ Kayce now returns to lead a powerful new spin-off: Y: Marshals.

This next chapter in the Yellowstone universe finds Kayce navigating a dangerous new path—not on the ranch, but in the crosshairs of Montana’s criminal underworld. And as Entertainment Weekly reveals in an exclusive first look, he’s doing it with a badge.

From Cowboy to Marshal: The Official Premise

According to the show’s logline, Y: Marshals follows Kayce as he joins an elite unit of U.S. Marshals, combining his cowboy grit and Navy SEAL instincts to serve as the last line of defense in a region overrun with violence.

“I’m changing paths, trying to find a new beginning,” Kayce says in the first footage, shown galloping after suspects on horseback.

Still haunted by the trauma of losing both his father John Dutton (Kevin Costner) and brother Jamie (Wes Bentley), Kayce is seeking purpose beyond blood and legacy. He’s kept the East Camp of the Yellowstone for his wife Monica (Kelsey Asbille) and son Tate (Brecken Merrill)—but peace won’t come easy.

A Cast Full of Returning Favorites and New Faces

Grimes leads a solid ensemble with Yellowstone alums returning, including:

• Kelsey Asbille as Monica Dutton

• Brecken Merrill as Tate Dutton

• Gil Birmingham as Thomas Rainwater

• Mo Brings Plenty as Mo

They’re joined by new series regulars:

• Logan Marshall-Green (Upgrade)

• Arielle Kebbel (Rescue: HI-Surf)

• Ash Santos (Mayor of Kingstown)

• Tatanka Means (Killers of the Flower Moon)

• Brett Cullen (Winning Time) as the team’s commanding officer

Sheridan Expands the Universe Again

Creator Taylor Sheridan returns as executive producer, with SEAL Team’s Spencer Hudnut serving as showrunner. With Sheridan’s signature blend of raw emotion and high-stakes frontier justice, Y: Marshals promises to bring gritty procedural drama to the Yellowstone world—this time with federal firepower.

When to Expect Y: Marshals

The series is set to premiere mid-season on CBS, offering both network reach and the Yellowstone franchise’s cinematic flair.
