CBS’s Marshals’ short first season concludes with episode 13, which finds Kayce deciding East Camp’s future and the team saying goodbye to a key member. The season finale ends with a massive betrayal exposed and the fate of two members of the team left hanging.

(The following is a recap of season one’s finale, “Wolves at the Door,” and there are spoilers.)

Kayce (Luke Grimes) steps onto the porch, pausing to look around East Camp, before saddling up and heading out to visit Monica’s private memorial spot.

Bartender Maddie (Morgan Lindholm) confides in her dad that Miles isn’t handling the suspension or Sabrina’s death well. Belle (Arielle Kebbel) also shows up at the bar, reminding Cal (Logan Marshall-Green) he promised to stop drinking beer and start eating better. Belle scheduled an appointment with the best oncologist around, and Cal’s not looking forward to dealing with it alone. She suggests that he confide in Maddie. Cal refuses.

Miles (Tatanka Means) pops into Chairman Thomas Rainwater’s office and learns he’s no longer needed to speak with the senators. A suspended marshal speaking on the rez’s behalf won’t go over well.

Kayce appears to still be considering selling East Camp to Tom Weaver (Chris Mulkey), and Tom arrives with Dolly (Ellyn Jameson) and his ranch foreman, Jeb (Kevin McNamara). Jeb asks if it’s okay if he looks around since Tom wants to run 1,000 cattle on the property. Tom hands over his formal offer for East Camp and Kayce reminds him the Duttons have owned the land for 150 years. There’s a lot of blood, sweat, and tears poured into the soil. Tom assures him his offer will change his fortune.

Kayce explains that while he’s currently standing in the ashes of a fire and staring at the house where Monica died, fresh grass will grow in the spring. He’s used to losing what he loves, but East Camp is something he can hold onto. Kayce turns down Tom’s offer and although he’s disappointed, Tom’s also happy for him.

Kayce shows up at the station with a much-improved attitude that Belle and Andrea (Ash Santos) immediately notice. He’s not only keeping East Camp, but he’s also turning part of it into an equine therapy center for vets. And he’s going to name it after Garrett. Cal and the team support the idea.

Their boss, Harry Gifford (Brett Cullen), breaks the news that Andrea couldn’t; she’s leaving Montana and returning to DC. She didn’t know how to tell them she’s leaving tomorrow.

Meanwhile, Miles rides with Thomas (Gil Birmingham) and Mo (Mo Brings Plenty) to the airport, and Thomas is amused that Miles sounds a lot like Kayce when he tries to justify disobeying orders. Suddenly an SUV appears out of nowhere and almost T-bones them. A gun appears out the window and Miles protects Thomas with his body. Bullets fly and then the SUV speeds off.

Andrea gives Kayce a hard time about dating Dolly after turning down her dad. Kayce jokes that he won’t miss her teasing and then gets serious when he asks her to reconsider. Andrea admits it was a tough decision to make.

They’re still talking about her impending departure when Kayce gets a call about the attack on Rainwater. He immediately grabs his bag and heads home, believing keeping Rainwater at East Camp is the safest place.

Miles, Mo, Thomas, and Kayce watch East Camp’s security cameras, but Mo’s sure he wasn’t followed. Rainwater apologizes for bringing his problems to East Camp. Tate (Brecken Merrill) was supposed to leave but he decided to stay by his dad’s side. Kayce sent all the ranch hands home.

They believe the incident has to do with the bomb attack during the mine demonstration. Rainwater’s certain the attack was meant to keep them from meeting with the senators.

Miles heads to Broken Rock to hunt for clues.

Meanwhile, Andrea, Cal, and Belle are tasked with tracking down Rudy Carpenter, the fugitive Cal and Kayce let go while they were on their way to rescue Tom Weaver. He’s apparently meeting someone at a local motel, and they stake it out while giving Andrea a hard time. They think Montana’s grown on her and that she fits in better away from big cities.

Kayce and Rainwater are reminiscing about the past when they realize someone’s jamming the ranch’s Wi-Fi signal. Kayce has Mo and Thomas watch Tate while he rides out to check on a tribal officer they left guarding the ranch’s gate. Kayce’s able to reach Cal and informs him that the officer’s dead and the attackers are moving toward his cabin.

Kayce grabs a flare gun out of the police car before heading back to his cabin. He fires it into the air, and Mo understands it’s a signal that something’s wrong. Mo sends Tate and Thomas upstairs and prepares for a gun fight.

Cal decides to let Rudy escape again. It’s more important to help Kayce, even if Gifford gets upset.

Gunfire fills the cabin and Mo’s the only one downstairs able to fire back. Kayce returns and circles behind the attackers. He kills two men before coming under gunfire himself. He makes a run for it before realizing there are a dozen or so men attacking his cabin. He’s hit and goes down with a thud.

A man crashes open the cabin door, knocking it into Mo. Mo’s able to stay on his feet and fight back. It’s a life-or-death struggle over the man’s knife. Mo emerges on top and kills him.

Outside, the men approach the spot where Kayce fell as he struggles to get back into the fight. Suddenly, his team (with Miles) shows up and begins taking out the attackers. Kayce makes a run for it toward them as they lay down cover fire.

Kayce chases after a fleeing vehicle on horseback while the team continues with the gunfight. He comes upon the vehicle not far away, and it’s rolled over. The occupants survived the crash but are no match for Kayce’s sharpshooting skills.

Mo has joined the gunfight and helps take down the remaining men outside.

Thomas uses a bed for cover and waits, gun aimed at the bedroom door. He gets off a few shots as an attacker breaks through the door but it’s Tate who kills the man. Kayce arrives seconds later and fortunately they don’t shoot him.

After things calm down, Kayce apologizes to Tate for putting him in that position. Cal informs Rainwater and the others that there are 10 men down outside and hopefully they’ll have their identities soon. Someone knew Rainwater would be there, and these men were professionals. It’s no longer safe at East Camp and Cal suggests they return to the compound.

Back at the station, the men have been IDed as international mercenaries. But so far Belle hasn’t found a connection between any of the men. The team learns the tribal officer who was shot had called Councilmember Irons’ office after he arrived at East Camp. (Irons had already been mentioned as a possible organizer.)

Cal suggests that Kayce hang out at the station with Tate while he, Belle, and Andrea interview Irons. Kayce admits to Tate that he wanted to break the Dutton family cycle of violence, but it didn’t work. Miles joins them and Kayce thanks him for helping in the gunfight.

Belle, Andrea, and Cal find Irons’ vehicle in a remote area and are stunned to see that Irons is dead leaning against it. They assume he killed himself after the attack didn’t work.

Thomas and Mo speak with Kayce and Miles about Irons’ death, and Thomas doesn’t believe he killed himself. Even if he did, he had to have been working for someone else.

A motorcade comes to collect Rainwater, and both he and Mo thank Kayce for keeping them safe. “I’m proud to call you my brother,” says Rainwater.

Cal’s also proud of Miles for having the team’s backs. Miles admits he has a problem keeping his judgment under control. Cal reinstates him to desk duty, and Miles is okay with that.

Later, they kick back and relax a bit while still determined to find out where Irons’ money to pay mercenaries came from. Gifford arrives and praises their work, admitting the team’s exceeded his expectations. He wishes Andrea well in her new assignment.

Andrea, Miles, and Belle goof around with a taser and foosball, and Tate thinks it feels like the old Yellowstone bunkhouse. Kayce confesses he never felt at home there. Cal joins the foosball fun as Andrea steps away to say goodbye to Kayce. They share a friendly hug as Kayce leaves.

Miles joins Maddie for a dance at the bar. She’s happy he got his badge back, and Miles says the only things he cares about are her and his job. Cal watches them dance and calls Belle, but she doesn’t answer. She’s riding home with her hubby from their son’s talent show when she confesses that she’s in debt and needs his help. He’s stunned that she owes $20,000 and doesn’t want to help pay off her debt.

Andrea’s alone at the station when she takes her new cowboy hat out of her locker. She holds it, obviously conflicted about leaving the team.

Miles leaves the bar to join Rainwater in DC.

Maddie hands her dad a beer, relieved he gave Miles a second chance. For the first time ever, she comes out from behind the bar and sits next to her dad. He’s shocked and she says she’s ready to talk. Maddie even calls him dad.

The following morning Andrea’s at the station when Belle and Cal arrive. They joke that she’s not really going to leave, and she reveals the coroner doesn’t think Irons killed himself. The coroner didn’t find gunpowder on his hands and had defensive wounds. Andrea also learned that although the tribal cop called him, Irons wasn’t there to answer.

Andrea believes an East Camp ranch hand called someone with Rainwater’s location after being sent home early. Andrea wants to help them interview the guy, but Cal reminds her that she needs to catch a flight. He gives Andrea a parting hug and tells her to make the team proud. Belle jokes that she’s not going to be able to handle the frat house without her, and Andrea assures her she’s capable of it. Andrea respects Belle for never settling. They share a goodbye hug, too.

Kayce receives a text from Mo confirming Rainwater was able to get a 60-day suspension on the mine. Plus, there will be a review of alternate sites. Tate feels like Kayce brought life back to East Camp after joining the marshals.

Tom and Dolly show up to check on Kayce and Tate. Tom offers Tate a trip bass fishing in Texas and Tate’s so excited he starts packing immediately. Dolly’s going to stick around but Tom’s heading to Texas too.

Belle informs Cal that although she didn’t want to go with him to Salt Lake City because of work boundaries, she’s changed her mind. They both deserve partners who will have their backs.

Cal and Belle knock on the ranch hand’s door and Belle looks through a window and sees him dead on the floor. As they’re about to bust in, a truck pulls up outside. They stare at the driver and he smiles. He drives off, leaving two shooters who begin firing at them as soon as the truck’s out of the way. The driver is Tom Weaver’s foreman, Jeb!

Dolly and Kayce ride around the ranch as Tate and Tom arrive at the private airport. Jeb joins them there and tells Tom that “it’s handled.”
