During a tense night on a desolate desert road, a young woman is chased by a car. A man hands her a gun with one bullet, she loads it, and fires at the oncoming vehicle, but the car crashes into her. The dawn reveals Roberta “Bobbi” Torres [Britni Camacho] driving her 1977 Ford Mustang along a sun-scorched highway, when her sister Anna [Emily Pineda] calls, urging her to leave her abusive boyfriend Rhett.
At a remote gas station, the sheriff Bilstein [John Schwab] offers her a soda, which she declines. Anna calls again, drawing a sharp comparison between Rhett and their father that triggers Bobbi’s anger. She floors the accelerator, but a pull-over by the same sheriff ends with him accusing her of damaging his light-bar, demanding $300, and confiscating her phone. The roadside tension deepens as the sheriff’s authority overpowers the moment.
Back at the gas station, the ATM is broken and Bobbi’s card is declined. The attendant buys her a beer and warns her about the sheriff, urging her to leave the county while she can. The chase continues as the sheriff ambushes Bobbi, shoots out her car’s lights and tire, and harasses her, taking her license and insisting on payment. Bobbi escapes on foot, the landscape a harsh, open expanse bearing down on her.
At a diner, Bobbi sifts through change to call Rhett, who accuses her of having an affair with the sheriff and hangs up. She meets a waitress, Amy [Sydney Brumfield], whose relief is short‑lived as the sheriff arrives and traps Bobbi inside. She calls 911 and then her sister, but the sheriff returns her belongings, leaving her more confused and vulnerable than before. Amy, fired for the money Bobbi stole, is offered a ride; suddenly, a gunshot rings out and Amy is hit, and Bobbi spots the sheriff’s car closing in.
The sheriff ultimately corners Bobbi, frames her for murder, and manipulates a truck driver who is then killed. Bobbi speeds away as her car overheats and she’s forced to abandon it at a scrapyard, where she confronts the simple-minded attendant, Ed [Travis Lincoln Cox], in a tense confrontation. Inside the yard, she discovers a wall of drivers’ licenses before the sheriff appears and confesses his crimes, a chilling revelation that connects years of abuse to his calculated cruelty.
As Bobbi tries to escape, Ed, the sheriff’s brother, ambushes and knocks her unconscious. She awakens to find herself bound and tormented by the sheriff and Ed, learning that the sheriff is also Ed’s father, born from a history of abuse. The sheriff rants about his mother, revealing a blade forged from her jawbone and offering Bobbi a twisted chance at freedom. Refusing his game, Bobbi provokes him, triggering a brutal act of mutilation. When she regains her footing, she seizes the jawbone knife and makes a break for it.
Awakening untied, Bobbi pockets the weapon and sprints across the desert, eventually reaching a road with the sheriff’s cruiser in pursuit and a cruel game of distance begins. Exhausted, she collapses as the sheriff records the distance, offering water and a gun with one bullet. She loads the gun, seemingly shooting herself, but the sheriff finds no head wound—only blood in her mouth—and Bobbi stabs him with the jawbone knife, stealing his cruiser. The sheriff returns with the keys, but Bobbi disarms him, knocks him aside with a rock, and escapes in the stolen vehicle, watching him rise in the mirror as she drives toward him.
At a garage, she recovers her tongue and packs it in ice for reattachment surgery. Startled by Ed, she uses a wrecking bar to kill him. She then collects all the drivers’ licenses of past victims to use as evidence, a grim trophy of the sheriff’s crimes. When Rhett calls again, she hurls the phone away, finally rejecting his control, and drives toward the city lights as dawn breaks, the horizon bright with unknown possibilities and a sense of hard‑won freedom.
