While heading back to West Texas from Mexico, Tom Buchanan embarks on a journey that leads him straight into the heart of a tense and dangerous conflict in a small California border town called Agry. As he navigates the local political landscape, he becomes unintentionally caught up in a fierce feud involving the powerful and sometimes ruthless Agry family.
The story kicks off with Tom getting into a confrontation in self-defense when he punches a drunken young man, Roy Agry. Roy, played by Barry Kelley, responds with threats, vowing to kill Tom. Just moments after their altercation, Roy is attacked and killed by Juan de la Vega, a brave young vaquero portrayed by Manuel Rojas. Juan explains later that he was compelled to act because Roy had assaulted his sister, adding a layer of personal motivation to his daring act.
Soon after this incident, Tom finds himself entangled in rising tensions as the town reacts to Roy's death. Juan is arrested, and Tom protests his innocence, but the situation quickly spirals. The townspeople and some officials try to piece together what happened, and accusations begin to swirl. Rumors spread that Tom and Juan had collaborated in planning Roy’s murder, which complicates matters further.
Eventually, a lynching is organized by the community, but Judge Simon Agry (played by Tol Avery) intervenes, publicly insisting he will ensure a fair trial. Behind closed doors, however, the judge, who is also Roy's father, is conspiring to extort Juan’s wealthy family for his son's release. This betrayal reveals the corruption and greed running through the town’s leadership.
During the trial, the evidence is muddled and biased. Tom is eventually acquitted, but Juan, who chooses not to put up a defense, is found guilty and sentenced to hang. Tom attempts to intervene and secure Juan’s freedom, but Sheriff Lew Agry (representing the Agry clan and played by L.Q. Jones) pressures Tom to leave town and confiscates his $2,000. Tom vows to return and retrieve his money, setting up a rivalry and conflict that will unfold further.
Sheriff Lew then orders two deputies to escort Tom out of town, ostensibly to keep him safe—but in truth, they are instructed to kill him. However, the plan is thwarted when Pecos Hill (a character played by Roy Jenson)—a fellow Texan who feels a kinship with Tom—kills the deputy trying to betray him. Recognizing the bond they share, Pecos agrees to join Tom in his quest for justice and peace. The two decide to rest temporarily at an abandoned shack before Tom heads into town to confront his problems and reclaim his stolen money.
Meanwhile, the de la Vega family, represented by Gomez (played by Joe De Santis), attempts to negotiate Juan’s release. They offer a generous gift of thirty high-quality horses, but Judge Agry demands a much larger sum—$50,000 in cash. The situation becomes more complicated when Amos Agry (played by Peter Whitney) overhears the deal and informs Sheriff Lew, who devises a plan to steal the ransom money for himself.
Gomez travels to Agry with the money, but the judge sends Abe Carbo (played by Craig Stevens) to retrieve Juan from jail—only to find the cell empty. It turns out Lew has orchestrated a scheme to keep the money and manipulate the situation to his advantage. Tom, meanwhile, returns to town, forces Lew at gunpoint to take the money out of his safe, and prepares to leave with his gains.
However, chaos erupts again when Juan is recaptured, and Tom himself is thrown into jail alongside Juan in a final twist. The townspeople, fed up with the delays and the chaos, grow restless and tense. Judge Agry goes to the town to confront Gomez and Lew, which leads to a gunfight breaking out in the street. During the shootout, the $50,000 ransom bags are accidentally spilled, inciting a tense standoff where both Judge Agry and Sheriff Lew Agry fatally wound each other, dying in a tragic and ironic turn of events.
In the aftermath, Abe Carbo, a gunfighter played by Craig Stevens, inherits the town, implying a shift in power dynamics. Juan is finally freed, and the ransom money is returned to the de la Vega family, restoring some justice. Meanwhile, Tom resumes his journey to Texas, having navigated a web of treachery, violence, and moral ambiguity, leaving the small town behind and seeking peace in the wider world.
Throughout the story, themes of justice, loyalty, and corruption are thoroughly explored against the rugged backdrop of the Old West. The chaos and violence highlight how intertwined personal vendettas and greed can be in a landscape where law and order are often overshadowed by the desire for power, wealth, and survival. The film closes with a sense of bittersweet resolution, emphasizing the cost of justice and the hope for a fresh start beyond the chaos of Agry.
