In the small, picturesque town of Hemingford, Nebraska, nestled near the ominous backdrop of Gatlin, an unsettling atmosphere envelops the unsuspecting residents. It has been two days since the chilling occurrences in Gatlin, and in a show of compassion, the locals have welcomed the surviving children into their community. However, they remain blissfully unaware of the sinister forces that these children carry with them from their haunting past.
Amidst this looming threat is John Garrett, a city reporter attempting to revive his dwindling career by investigating the newly adopted children. His personal life is equally tumultuous as he wrestles with tensions between himself and his son, Danny, stemming from John's unsuccessful relationship with Danny's mother. This fraught dynamic simmers quietly beneath the surface.
As John delves into the intricate relationships within Hemingford, he encounters two former colleagues, Bobby Knite and Wayde McKenzie, who are preparing to leave town. Their ill-fated decision to take a shortcut through a nearby cornfield leads them to become victims of a terrifying storm that descends upon them with ferocity.
While navigating the chaos around him, John is irresistibly drawn to Angela Casual, the owner of a charming bed-and-breakfast. Their developing romance offers him a temporary escape from the surrounding turmoil. As he seeks answers regarding the children, he forms a bond with Lacey, a local orphan who shares her chilling experiences from Gatlin, adding another layer of desperation to John's investigation.
The town's sinister nature soon reveals itself as Micah and the other children unleash a wave of terror upon Hemingford. Their malevolent rampage peaks with the horrifying murder of Ruby Burke, whose house is deliberately destroyed, crushing her beneath it. The brutality escalates as David Simpson falls victim to Micah and a voodoo doll during a church service, showcasing the children’s frighteningly dark capabilities.
Driven by a growing sense of dread, John approaches the town doctor for help, only to be met with suspicion and later betrayal, as the doctor reports him to the sheriff for his inquiries. The doctor then meets a gruesome fate at the hands of the very children he sought to protect, leaving his clinic stained with blood.
As chaos grips the community, Micah and the children continue their brutal campaign, eliminating Mrs. West in the street under the guise of an accident. In this haunted setting, John fights to survive against a seemingly supernatural evil.
Realization dawns on him when he allies with Frank Red Bear, a knowledgeable Native American professor from the local university. Together, they strive to untangle the web of death and chaos enveloping their town. Frank's expertise in ancient rock art becomes critical, as he unveils the secretive power of the land that amplifies both virtuous and malevolent intentions, particularly among children. He recounts a chilling story of children who once turned on their elders, only for the cycle of violence to be halted by a ritual funeral pyre that allowed a good spirit to arise. Frank emphasizes that these ancient markings signify an unfinished prophecy, one where good has not yet conquered evil.
In their quest for answers, John and Frank stumble upon an unsettling discovery at the town's grain storage facility—residents are selling spoiled grain mixed with fresh produce, creating a toxic environment that exacerbates the children's disturbing behavior.
Their investigation is cut short when the Sheriff captures them, leaving them to the mercy of a merciless corn harvester. Yet, they manage to escape this perilous situation, prompting John to probe deeper into the supernatural forces at play. Frank reveals legends of a vengeful spirit, dubbed He Who Walks Behind the Rows, thought to enact revenge for transgressions against the land. As tension escalates, John and Frank must confront the dark legacy that threatens their townsfolk and the children engulfed in supernatural terror.
When the Hemingford community gathers for an emergency town hall meeting, the children orchestrate a treacherous uprising, trapping the adults and setting the building ablaze, resulting in devastating losses. As the chaos unfolds, Angela and Lacey are ensnared by the child antagonists, with Danny coerced into participating in a horrifying ritual sacrifice involving Lacey, forcing John and Frank to race against time to save them.
Arriving in their trusty harvester, Frank is hit by an arrow shot by one of the malevolent youths, leaving him injured. John and Danny leap into action, rescuing Lacey and Angela from the clutches of the children as they fight to escape the endless expanse of corn. Despite their efforts, they are caught in a loop that leads them back to the same treacherous spot.
Amidst this chaos, Micah attempts to wield the dark powers of He Who Walks Behind the Rows, but Frank's resistance leads to an unintended consequence that ultimately frees Micah from his possession. Tragically, however, Danny arrives too late to prevent Micah’s demise as he is violently pulled into the machinery.
As the ordeal concludes, the remaining children scatter, leaving John, Danny, Angela, and Lacey to find their way to safety. Together, John and Danny find comfort in their bond while honoring Frank with a traditional Native American funeral pyre. They begin to envision a hopeful future alongside Angela and Lacey.
In an epilogue, Frank's spirit transcends into a guardian of the land, its essence immortalized in the ancient rock paintings, underscoring the profound cycle of existence that has come full circle.
