Cal's week was fraught with tension as his personal life took a hit from seemingly all directions. The first blow came in the form of Garrett, a former SEAL teammate of both Kayce and Cal, played in his acting debut by country music singer Riley Green. While Kayce and Garrett still share a close bond, the animosity between the newcomer and Cal was immediately apparent. This tension stems from their "fourth musketeer," Rhoner, a former brother in arms who was killed in combat in one of the season's early episodes. While Kayce seems to have largely moved past blaming Cal for Rhoner's death, Garrett clearly has not, also blaming Cal for (in some as yet unrevealed way) getting him kicked out of the SEALs.
Garrett, who struggles with returning to civilian life as a traveling musician, seems content to settle in at Kayce's house for a while. However, this isn't the only challenge Cal faces this week. He also has to deal with the fallout from his ill-fated kiss with Belle and the revelation that Miles is dating his daughter, Maddie. Despite his insistence on keeping things professional, Cal is clearly taking his feelings out on both Belle and Miles (Belle for rejecting him, Miles for making a connection with his daughter when Maddie refuses to let him back into her life) when he sidelines them during an investigation of this week's baddie, Reed Pollard.
Cited as a "modern-day Dillinger," Pollard is a bank robber who has been a longtime denizen of the FBI's Most Wanted list. The team just so happens to have received an anonymous tip that he's planning a heist nearby. With a lead that he's hiding out at the rodeo grounds, Cal, Kayce, and Andrea attempt a raid on the property, only to find themselves ambushed. The team takes out all but one of the assailants, presumably Pollard, who manages to escape, but there's more to the situation than meets the eye.
After managing to track down the escapee, who died of his wounds from the shootout, they realize that Pollard wasn't among the crew. Adding to the mystery, none of the men who attacked them have any connection to Pollard or one another, nor any criminal records. While Kayce makes a questionably timed trip home to check on Garrett—whom he finds in the throes of a nightmare about Rhoner's death—Cal sends Andrea off to the ballistics lab alone to have the shooters' guns analyzed while he himself slips off to an equally questionably-timed doctor's appointment.
As if Cal didn't have enough to deal with this episode, the doctor implies that he's having some sort of serious health issue. Though the audio bleeds out, leaving it unclear exactly what condition he's suffering from, it's fair to expect this to be a significant plot point moving forward.
That will have to wait for another episode though, because this outing ramps into high gear when Andrea, on her way to the ballistics lab, is T-boned by another vehicle.
Returning to headquarters, the case has taken a more bizarre turn as Belle has managed to track down Pollard, who has been in jail in New Mexico for quite some time, with no evidence linking him to any heists in Montana. Given the anonymous tip that initially led them onto the case, the team begins to suspect that this has all been a setup aimed at them. This suspicion is confirmed when Andrea's SUV is found and CCTV footage reveals that she was kidnapped from the scene.
As the team dedicates all of their resources to tracking her down, Andrea is taken to a property seemingly located in the middle of nowhere. There, she discovers the mastermind behind this entire scheme: Randal Clegg. Having lost his demolitions contract with the nearby mines after his sons orchestrated mass shooting events on the Broken Rock reservation, and subsequently losing one of said sons in a shootout with the Marshals team and another to jail for the incident, Clegg apparently has nothing left to lose and means to take out his vengeance on the marshals.
Fortunately, the team manages to link the van in which Andrea was kidnapped to Clegg, and they rush to her rescue. They can't afford to wait for backup (again), but things seem quiet on Clegg's land... at least until the team finds themselves in a shootout with a veritable army of Clegg's supporters. The episode comes to a dramatic close with them pinned down by gunfire and Andrea tied up in Clegg's basement, meaning we'll have to wait another week to see how, and if, all of the marshals make it out alive.
