The crime thriller “Duster,” set in the 1970s, maintains its nostalgic grittiness in episode four, intensifying the peril for both Jim and Nina as their storylines deepen. Following three episodes of simmering tension and lingering secrets, the latest installment delivers a fast-paced hour filled with shifting loyalties, car thefts, cartel killers, and FBI schemes. Jim finds himself entangled in a dangerous business arrangement while Nina inches closer to the potential cover-up—and now they are both in greater danger than ever.

The plot of Duster Episode 4 revolves around a classic noir theme: a simple task that goes awry. Jim promises to take care of Ezra Saxon’s son, Royce. What begins as a straightforward drive escalates into bloodshed, retribution, and an unexpected alliance with a hitman. Meanwhile, Nina and her partner Awan investigate a lingering mystery left by the disgraced FBI agent, Leland Breen. They uncover a VHS tape hidden on tribal land that changes everything about the case. The tape could expose a conspiracy within the Bureau itself.

Duster creates a paradox throughout its narrative, with characters continuously drifting between the extremes of truth and deception, loyalty and betrayal, and legality and crime. In episode 4, Jim's moral relativity parallels Nina’s unyielding resolve for truth more than ever, despite them being on different narrative tracks. The conclusion of this episode does not merely mark the first shift of the dial; it also prepares the audience for a foreboding second half of the season.

In a few short breadcrumbs, Duster weaves a puzzling mystery that will captivate readers of classic crime fiction while modernizing the pacing and characters. Through Jim’s undignified means of survival and Nina’s fierce desire to investigate, episode 4 sets its lead cast on a path to confront threats far more perilous than they realize.


Why Jim partners with Enrique “The Blade” after their brutal desert brawl in Duster

Jim’s meeting with cartel enforcer Enrique, aka “The Blade,” is both pivotal and brutal. What begins as a vicious clash in a desert auto shop transforms into a strange, albeit cordial, encounter between two frayed men. They take a sip from a shared drink after their tussle, and upon discovering that their vehicle has been stolen by bumbling bandits, they work together to retrieve it. It’s a unique blend of misguided friendship in a reality forged on suspicion.

But Jim’s decision to give Enrique Howard Hughes’ luxury car—a symbol of wealth and power—carries deeper meaning. Not only is it a peace offering for breaking an earlier deal with the cartel, but it’s also a calculated move. Jim understands the significance of symbolic gestures in his world. Handing over the car secures him a future favor—or at least buys him time to figure out how to spin the loss to Ezra Saxon. Whether it’ll cost him Saxon’s trust remains to be seen, but for now, Jim plays both sides to survive.

As Jim indulges in his criminal game, Nina dives deep into the rot of the Bureau. The discovery of a VHS tape on the Navajo Nation by her and Awan carries a startling revelation they never thought possible. The tape has a warning from a former agent named Leland Breen telling them they need to “expose Xavier and his network” and chillingly “trust no one.” It seems to go beyond Ezra Saxon; this has powerful implications for other individuals within the FBI who are managing everything from behind the curtains.

Nina’s path is laid out for her—seeking justice for Joey, on behalf of the victims Saxon preyed upon, and fighting for the truth. However, the tape reveals Xavier, a new foe who may connect Saxon to Nina’s agency. With potential antagonists within her own ranks, Nina feels more isolated than ever. The pressure surrounding decisions about who is trustworthy, including Awan, is sure to escalate as she inches closer to the core of a cover-up that could shape the rest of the season.

The fourth episode of Duster not only deepens the story but also reveals the stakes. While Jim teams up with old foes, Nina appears to uncover a massive betrayal from the FBI, bringing the series to a balance of explosive action and nuanced complexity. Moving forward, the latter half of the season must confront the consequences of their actions. Whether they self-destruct or triumph will depend on how much they are willing to compromise their principles.
