In the dusty town of Cuchillo, New Mexico, during the year 1887, a crew of five merciless outlaws, with Henry at the helm, execute an audacious bank heist that ends in a violent shoot-out with the town's residents. Hot on their trail are a group of bounty hunters led by Josiah, whose relentless pursuit is fueled by a vow to bring the criminals to justice— and they are just hours behind.
As the outlaws face escalating peril, their numbers dwindle down to four after a tragic encounter. They cross paths with an unsuspecting couple, Charlie's aunt and uncle, who provide them with vital sustenance. However, their kindness quickly turns fatal as Henry and his gang ruthlessly eliminate them, terrified that they might reveal their location for the tempting reward of $8000 on their heads.
Meanwhile, Josiah and his posse discover the horrific aftermath of the couple's murder, where they encounter Lulu, Charlie's young granddaughter, who was hiding nearby. With tears in her eyes, she divulges the chilling news that the outlaws are headed for White Sands, a perilous area that complicates their pursuit.
With one outlaw succumbing to fatigue and compassionately put out of his misery by his comrades, the remaining trio heads towards the Tildon farm, home to Preacher George, Ada, and their teenage daughters, Charlotte and Florence. Cloaked in false hospitality, they plan to plunder the farm at sundown.
As darkness envelops the night, the outlaws erupt into the farmhouse, fueled by whiskey and depravity. Young Florence, barely 15, catches Henry's gaze, only for her innocence to be viciously violated by Charlie and Little Joe. Preacher George pleads for his family’s safety, referencing the tragic loss the town suffered due to consumption—the chapel on their land standing as a grim reminder of the past.
Henry instructs Little Joe to keep watch outside and guides Charlotte into the night. Despite an initial attempt at a more "civilized" interaction with Florence, his desires are thwarted when she tries to reciprocate, leading him to angrily command her to stop. Charlotte rejects Little Joe’s advances, finding them repulsive.
As the night unfolds in chaos, Charlie cruelly assaults Ada, while George remains oblivious, asleep nearby. Fueled by her fascination with Henry, Florence decides to flee with him, despite her family's opposition. In a dramatic confrontation, she raises a gun against George—only for Henry to intervene, stopping her from acting violently. In a shocking twist, she turns the gun on Charlotte, fatally shooting her.
Curiosity leads Henry to question George about Charlotte’s infertility. Initially, George attributes it to fever, but when pressed, he reveals the grave truth: an incestuous relationship with Charlotte at the tender age of 11 has left her unable to bear children due to a bungled abortion.
In a heinous command, Henry orders Little Joe to perpetrate a despicable act against George, but ultimately calls off the assault, stating it was merely a scare tactic. Florence re-emerges, armed with a shotgun, and mercilessly beats George to death, wishing to make him suffer rather than die swiftly.
When questioned about Charlotte's murder, Florence chillingly admits to killing her for the thrill of the twisted relationship between George and Charlotte. Choosing to spare Ada, she leaves behind a bag of gold coins and the outlaws continue on their path. However, Josiah arrives just in time to find the traumatized Ada, and upon stealing the coin bag, he meets a brutal end when Ada shoots him dead.
The relentless group eventually crosses into Mexico, where Florence enacts her vengeance by executing the three remaining men—Charlie falls immediately, and Little Joe lingers until Henry mercifully ends his suffering. In an emotional moment, Florence expresses regret to Henry, revealing that her initial desire was to escape with him, but she was ultimately swayed by the promise of reward money. Faced with heartbreak, Henry takes his own life.
In a chilling conclusion, Florence beheads the three outlaws, meticulously packages their remains for the bounty, and makes her return to her previous existence. Back at the farm, Ada awaits her arrival, poised to reciprocate the violence she has suffered, thus completing the harrowing cycle of brutality.
