It’s no surprise that the series finale of Yellowstone didn’t mean the end of Taylor Sheridan’s universe and characters. Marshals is the first Yellowstone spin-off that takes place after the finale, however, so here’s what you need to know about whose story its going to tell.

What’s fun about this series is that, while set in the same universe as the family dramas we know and love–Yellowstone, 1883, and 1923–it is a different genre. Marshals is a police procedural. It follows a task force whose job is to protect Montana from outside attacks. There’s kind of nobody better for that job than a Dutton family member, who we must assume is basically local royalty. At least, from a certain point of view.

You know former Navy SEAL Kayce from Yellowstone. He is the eldest son of the dynastic Dutton family in the anchor series. In this new show, Kayce takes a new gig as, you guessed it, a U.S. Marshal in his local Montana.

Before he got on the ranch, Grimes played Elliott in the Fifty Shades movies. He cut his Western chops on Antoine Fuqua’s remake of The Magnificent Seven and the Clint Eastwood (ergo, Western adjacent) film American Sniper. He played a vampire named James on six episodes of True Blood. He was also a series regular on another big family show, Brothers and Sisters, as Ryan Lafferty.
