On Christmas Eve in Los Angeles, a LASD Sheriff is shot dead by an armed robber who had also robbed a convenience store and killed its owner. The alcoholic, hard‑driven detective Jerry Beck is assigned to the case, and his tough, relentless approach quickly sets him apart from his peers. While combing through police records, he spots a parolee named Bobby Burns who has just been released after a four‑year robbery sentence. Beck and a parole officer go to Burns’ home, hoping to corner him, only to find Burns’ college student brother, John Burns, who claims he hasn’t seen Burns and is merely staying for the holidays. A man bolts from the house and Beck gives chase, catching him after a foot pursuit; the man turns out to be one of Burns’ friends who is also on parole for armed robbery. The man tells Beck that he last saw Burns driving a maroon Ford Ranch Wagon on his way toward Bakersfield.
In Cottonwood, Arizona, Burns and his crew rob a Mexican bar and kill several patrons. A local police chief informs Beck of the brazen crime, and Beck heads there with the chief to pursue the case. They track Burns to a ranch thought to be his hideout, where Burns and his men ambush the officers with automatic weapons and manage to escape in the Ford. Beck retrieves a cache of documents Burns dropped—white‑supremacy propaganda, maps, and an address book—and sets his sights on a broader lead. His journey takes him to Bogan, Oklahoma, to track down one person listed in the book: Reverend Gebhardt, a leader within a white supremacist movement. Beck is joined by FBI Agent Arthur Kressler, and together they press toward Gebhardt’s church. There, Gebhardt speaks of the organization’s goal to cleanse America of “racial impurities” and denies ever having seen Burns, even as Burns himself lurks nearby, casing the church.
That night, Burns makes a bold move, forcing Beck into a dangerous confrontation while driving. Beck crashes his car into an oncoming police vehicle to break free, and during a fierce gunfight, he uses a matchbook to ignite a leaking gas line, triggering a fire that allows Burns and his men to slip away amid the chaos. Back in Los Angeles, Beck’s superiors grow increasingly frustrated by his performance, citing alcohol problems and rough behavior. They push for a psychiatric evaluation; after a tense session, Beck intimidates the psychiatrist enough to secure a clean bill of health, and he’s deemed fit for duty.
In Boulder, Colorado, Captain Dixon assigns a team of black officers to help track Burns. Beck and Kressler join him as they raid a paramilitary training camp connected to Aryan Nations and ambush Gebhardt and his followers. The trail goes cold, and personal frictions flare between Beck and Kressler, but Beck uncovers a concealed door that leads to a bunker. A brutal gunfight erupts, and Beck fatally wounds Burns in the ensuing moments. As Burns lies dying, he denies having killed the Los Angeles cop. At that moment, John unexpectedly steps out and confesses that he shot the officer to demonstrate his contempt for the police and his unwavering allegiance to white supremacy. Beck hurls a few cutting insults at John, who responds by firing back; when John runs out of bullets, Beck shoots him dead.
In a closing press conference, Chief Dixon announces that the FBI will revise its stance on white supremacist groups, crediting Kressler with the critical evidence gathered during the investigation. Outside, Dixon and Beck share a wary, if fleeting, bond as they part ways and reflect on the case’s consequences and the ongoing debate over extremism in America.
