Boyd shows up at Ava’s house in the middle of the night and is greeted by Ava’s raised shotgun.Boyd says he’s just there to say he’s sorry for all the wrongs he’s done Ava, both recently and in the past.Ava replies that he can repay her by never bothering her again.
After leaving Ava’s Boyd meets up with his cousin Johnny.It turns out Johnny’s the one who told Boyd about the drug shipment to begin with, only Johnny thought Boyd was going to hijack the truck and the two of them would go into business together.Instead, Boyd blew it up.Furious, Johnny sends Boyd on his way.
Ernesto and Pilar, the drivers Gio sent in the truck, have found Bo and told him about the truck and how the man who blew it up said “Fire in the hole” before firing his rocket launcher.Bo knows now that Boyd’s at fault.
Bo overruns Boyd’s camp, has his son Boyd beaten and forces him to leave his men and go into “exile.”
Meanwhile, in Lexington, Raylan’s brought his father Arlo into town in order to set him up as a confidential informant for more branches of law enforcement.Boyd’s blowing up of the drug shipment has escalated the entire situation.Raylan has Arlo staying in his hotel room while he waits for Assistant US Attorney Vasquez to be available.
Back in Harlan, as Boyd walks through the woods away form his camp, he hears a series of gunshots back in that direction.He runs back, only to find his men strung up to trees, all of them shot dead, and he falls to his knees with anguish.
At the courthouse, Raylan runs into Winona, who mentions to him that Gary isn’t living at home any more.
Meanwhile, Bo shows up at Raylan’s hotel room to talk with Arlo.Bo’s had men following Arlo, it turns out, and now Bo wants Arlo to do something for him to prove his loyalty.He wants Arlo to assist in the kidnapping of his own son, Raylan, so that Bo can hand him over to Gio, the Miami cartel boss.
When Raylan gets to his hotel that night, Arlo engages in some small talk, then tries to pull a gun on Raylan, but Raylan’s already got his pulled.Arlo explains to Raylan that the plan was for him to shoot Raylan in the leg, incapacitating him before Bo’s men come in from outside.Raylan shoots Arlo in the arm, instead.Bo’s men Heckle and Jeckle hear the shot and come inside, only to find Raylan’s gun drawn on them.They try to shoot him anyway and Raylan kills them both.
In Harlan, Bo kidnaps Ava, as insurance in case Arlo doesn’t come through.He also shoots Johnny in the gut as punishment for telling Bo about the drug shipment.
Boyd shows up at Raylan’s hotel room as Raylan’s cleaning up Arlo’s wound.He’s distraught about what Bo did to his men.Raylan almost immediately gets a phone call from Bo, letting Raylan know he’s got Ava, and to meet him in Bulletville to exchange his life for Ava’s.Boyd wants to go with Raylan, and Raylan agrees to it.
The next morning, Raylan and Boyd arrive at Bo’s cabin in Bulletville.Boyd sneaks around back while Raylan goes up to Bo and one of his men, ostensibly turning himself over.Boyd gets into the cabin and kills Hesler, who’s guarding Ava.The distraction of the gunshot enables Raylan to get the jump on Bo, killing Bo’s man and holding Bo at gunpoint.
Boyd steps out of the cabin with his gun trained on Bo.He doesn’t plan to let his father live.Instead, gunshots ring out from the surrounding forest, one of them hitting and apparently killing Bo.
Raylan and Boyd rush into the cabin and take cover along with Ava.Raylan’s able to kill a couple of the guys in the forest from inside the cabin, but Ernesto and Pilar still remain, and they’ve got automatic weapons.
Raylan and Pilar agree to come out of their hiding places unarmed to talk, but as they approach one another out in front of the cabin, Ernesto steps out from behind a truck and takes aim at Raylan.Fortunately, Boyd’s positioned himself in the forest and is able to kill Ernesto.Pilar gets in the truck and makes a run for it.Raylan’s about to go after Pilar when Boyd points a rifle at him.Boyd says he’s pretty sure Raylan’s out of bullets, and even if he’s not, he’s willing to bet Raylan’s still the best friend he’s got.Boyd gets in Raylan’s car and goes after Pilar.
Raylan points his gun at the escaping Boyd’s car and though he mimes firing it, he lets Boyd go.
Raylan’s father Arlo needs protection from an angry Bo Crowder, and he hopes the marshal’s service is willing to oblige.Raylan and his boss Art discuss the situation with Arlo and try to find out if Arlo can be a snitch for them.“What’s it pay?” Arlo asks.
Bo, meanwhile, is in Miami commiserating with Gio, the head of the Miami cartel.Gio introduces Bo to a couple of his people, Ernesto and Pilar.The two of them will be bringing the meth-cooking ingredients up to Harlan via truck in the near future.Gio is very clear with Bo that high expectations come with receiving this much product, and Bo assures him he’s up to the challenge, even with that pesky Raylan Givens hovering around.
Raylan and Art bring Assistant United States Attorney Vasquez in to talk to Arlo.Arlo wants money to give to Bo to get back on Bo’s good side, and Vasquez promises twenty thousand dollars.Raylan insists Arlo should wear a wire, but Arlo refuses and leaves.Art insists that Raylan get over his issues with Arlo and demands Raylan go down to Harlan and get Arlo back on board, with or without a wire.
Ava arrives at her house that night to find Bo’s men there, lounging on her furniture.They threaten her, making it clear Bo plans to make life a living hell for Ava as long as she’s in Harlan.Ava storms out and drives off into the night.
That same night Winona shows up at Raylan’s hotel room, and without saying much of anything she kisses him, and they make love.Then, just as wordlessly, Winona leaves.In the parking lot outside, a saddened Ava witnesses Winona leaving the hotel room.
The next day at a church in Harlan, Boyd takes to the pulpit to “testify,” making a point of saying people should stand up against evil, and this with his father Bo there in attendance. After the service, Boyd tells Bo that if Bo brings drugs into Harlan, Boyd will destroy it.Bo tells Boyd that if he does that he’ll be signing his own death warrant.
Meanwhile, Raylan arrives at the VFW looking for Arlo and finds a police tactical team outside about to storm the place.The new sheriff, Sheriff Davis, gives Raylan a hard time at first because she blames Raylan for Sheriff Hunter’s arrest, but eventually she tells him what’s going on.There’s a soldier inside named Lucky who’s so upset about not being able to join his team in Afghanistan that he’s taken a grenade inside and is threatening to blow himself up.As Raylan and the tactical team watch, Arlo tells a story about his own service that convinces Lucky to put down the grenade and choose to live.
After Lucky’s escorted from the VFW, Raylan has what almost passes as a civil chat with Arlo.Arlo even agrees to wear a wire.
Across town, Ava confronts Bo, shotgun in hand.Bo demands Ava leave Kentucky, but Ava still refuses, leaving them at something of an impasse.
Arlo, wearing a wire, goes to see Bo, but instead of trying to get information for the marshals, Arlo silently reveals the wire, scribbling messages back and forth with Bo on a piece of paper.He wants to feed disinformation to the marshals via the wire while getting paid for it by Bo.Bo says he’ll think about it.
That night, Raylan goes to see Ava.She reveals to him she saw Winona at his hotel the night before.She also tells him she can’t leave Harlan, no matter what Bo says.It’s her home.
In another part of Harlan, Ernesto and Pilar are forced to stop their truck full of drugs when they encounter a broken down truck in the middle of the road.They get out and chase away the driver, only to be waylaid by masked men, including one with a bazooka.“Fire in the hole!” the masked Boyd says as he blows the truck to smithereens.
Raylan and the marshals raid Boyd Crowder’s “church” camp on the grounds that they’re harboring a parolee in violation of his release.They take several of Boyd’s men back to the marshals’ office and try to get them to roll on Boyd, including one Mr. Dewey Crowe, Boyd’s incompetent lackey from his white supremacist days.The marshals get nothing, though, Boyd’s men all repeat after Boyd: “you strike at the shepherd that the sheep may scatter.”Except Dewey, that is, who gets it confused with baseball terminology.The marshals question Boyd as well, specifically about the meth lab explosion that killed the meth cooker inside, but Boyd won’t admit to anything.
Later on at the courthouse, Raylan runs into Winona.They make awkward small talk that includes Winona wondering if she left her hairclip at his hotel when she was patching him up.She also thanks Raylan again for helping Gary out of his situation.Are there some small sparks flying between the two of them?
Raylan goes to see Sheriff Hunter in prison and asks for his help getting Bo Crowder.Hunter reveals to Raylan that while Bo was in prison, he left Raylan’s father Arlo in charge of his criminal empire.Apparently Arlo did a crappy job, too, and Hunter implies Bo might be none too pleased.
Bo goes to see his son Boyd at Boyd’s camp.He tries to give Boyd some cash, explaining that ever since Boyd blew up that meth lab, every criminal in Harlan has been banging down Bo’s door to pay protection money.Boyd initially refuses the cash.Says that’s not why he did what he did.Bo won’t take no for an answer and as he leaves tells Boyd he’ll be in touch regarding where the “hand of God” should strike next.
Raylan and Art go to Harlan to see Arlo, but Arlo won’t say crap and won’t accept protection from the marshal service.
That same night, Raylan, Art, and Tim are summoned to the site of two dead bodies, the bodies of the other meth cookers they’ve been looking for.These two could’ve testified against Boyd.Bo’s the one who killed them, but Raylan and company don’t know that.For all they know it was Boyd himself.
The next day Arlo and Bo meet.Arlo defends himself, saying he did the best he could with Bo’s business, but Bo’s not in a forgiving mood.He demands fifty thousand from Arlo, and gives him twenty-four hours to come up with it.
Raylan comes across a hitchhiking Dewey Crowe, who’s been banished from Boyd’s camp for “onanism” (masturbation).Dewey tells Raylan that Boyd didn’t kill the other two meth cookers, but that it was Boyd’s disciple Bobby Joe who turned Boyd onto the meth lab to begin with.
Raylan and the marshals raid Boyd’s camp yet again, this time looking to get Bobby Joe.They don’t find him, but Boyd does give Raylan an enticing bit of information.He tells Raylan that Bowman Crowder, Ava’s ex-husband, was running Bo’s business along with Arlo while Bo was in prison.Once the marshals are gone, Boyd and his men uncover a buried Bobby Joe, who’s been hiding in a coffin with the camp’s guns the entire time.Apparently Dewey tipped Boyd off that Raylan was coming.
Raylan finds Ava at a bar near Harlan.Ava’s in a self-destructive frame of mind, and Raylan forcibly takes her out of the bar and then to Winona, asking Winona to take her in for the night.
Meanwhile, Arlo’s wife Helen confronts Arlo after finding her life savings missing.Arlo will admit no wrongdoing, saying he needed the money for various things over the years.Their fight is interrupted by gunshots through their front windows.Arlo and Helen run outside and return fire, but miss the truck the gunshots originated from.
Boyd thanks Dewey for the heads up on Raylan’s raid, but doesn’t forgive him for telling Raylan about Bobby Joe in the first place.He threatens to kill Dewey, but has a change of heart, instead simply telling Dewey to leave.
Bobby Joe, meanwhile, turns himself in to the marshals, taking complete responsibility for the meth lab bombing and claiming Boyd had nothing to do with it.
When Raylan returns to his hotel room, he finds Arlo there waiting for him…
