In Denver, Colorado, during the year 1978, families gather for a thrilling little league baseball game, where Finney Blake (Mason Thames) takes the pitcher's mound, supported by his spirited sister, Gwen (Madeleine McGraw). While Finney impressively achieves two strikes, a powerful blow from his rival, Bruce Yamada (Tristan Pravong), results in a home run victory for Bruce's team. Despite the competition, Bruce admires Finney's talent, offering him a moment of encouragement.
After the game, we witness Finney cruising through town on his bike, casually waving to schoolmates, when suddenly a black van lurks ominously nearby. This chilling moment foreshadows the darker elements of their lives—Finney and Gwen are subjected to the harsh realities of life with their father, an abusive alcoholic still grieving the tragic loss of their mother who took her own life.
As the siblings make their way to school, they stumble upon a tense confrontation where Moose (J Gaven Wilde), the local bully, finds himself on the receiving end of a brutal beating from Robin Arellano (Miguel Cazarez Mora). Shockingly, Robin proves to be an adept fighter, nullifying Moose's threats in a display of unexpected violence. During this chaos, Gwen brings up the unsettling rumors about a kidnapper known as “The Grabber” (Ethan Hawke), a reminder of the recent disappearance of Bruce.
At school, Finney faces his own tormentors, bullied by a trio of classmates, but his spirits are buoyed when Robin intervenes, warning the bullies to back off. Robin also offers sage advice, urging Finney to stand up for himself—a message that resonates deeply. Later, two detectives (E Roger Mitchell and Troy Rudeseal) arrive at the school to question Gwen about her dreams that seem eerily linked to the missing boys, including Bruce. Gwen shares her struggle to comprehend these visions, yearning to help those in need.
The following morning takes a dark turn as Finney awakes to hear his father vehemently assaulting Gwen—his frustration driven by the investigators' recent inquiries about her dreams and their possible connection to Bruce's case. In a desperate act of defiance, Gwen shatters her father's liquor bottle, amplifying his rage and leading to more violence. He forces her to deny the authenticity of her premonitions, the very same dreams that haunted their mother.
As the plot thickens, Robin finds himself confronted by The Grabber, drawing a direct line between the boys' tragic fates and this malevolent figure, who has been preying on the area’s youth. With the alarm of Robin's disappearance sent out to the neighborhood, the schoolyard bullies renew their assaults on Finney. But, fueled by love for her brother, Gwen valiantly steps in to defend him, her bravery is met with retaliation as she earns an injury in the process.
Later, during a science class, Finney is excited to be partnered with his crush, Donna (Rebecca Clarke), who empathizes with his struggles following the physical attacks. However, after parting ways with Gwen, Finney's world spirals further into chaos as he crosses paths with The Grabber's sinister vehicle, which masquerades as an ordinary presence in the community. The vibrant childhood innocence abruptly exits as The Grabber ensnares Finney, incapacitating him before transporting him to a hidden basement—a dark, inescapable prison.
The chilling confines of The Grabber's lair reveal not just the despair of captivity but also a twisted sense of reassurance as The Grabber attempts to convince Finney of his “specialness.” He presents Finney with a seemingly innocuous disconnected black phone, claiming it has mysteriously rung before. It isn’t long before this phone becomes a haunting lifeline—connecting Finney to the ghosts of other victims, including Bruce, whose shared experiences and pivotal advice light the faintest of hopes in Finney’s heart.
Alongside these supernatural exchanges, Gwen’s dreams illuminate a flashback of Bruce's cherished memories of baseball, interweaving their fates even more tightly. Through the guidance of his spectral companions—each tragically cut short by The Grabber—Finney learns survival tactics and the importance of self-empowerment.
As the investigation unfolds, detectives battle against time while Max (James Ransone), exposed as The Grabber's brother, uncovers the chilling truth within the walls of his own home. Simultaneously, Gwen, determined and resolute, finds herself collecting vital information from her dreams, which ultimately lead her to the very location that has ensnared her brother.
In a climactic turn of events, a decisive confrontation occurs when Finney utilizes all he has learned from the spectral children to outsmart The Grabber, inviting catharsis and empowerment. When the dust settles, Finney emerges victorious from the terrifying depths of despair, leading to a heartwarming reunion with Gwen, who throws her arms around him, celebrating his return. The siblings find solace in the sun's warmth, having navigated their darkest days together.
Finney's newfound confidence blooms as he returns to school with a legacy that reshapes his identity—no longer the bullied but rather a hero to those who once tormented him. The ghostly whispers of the past empower him to face the schoolyard with strength, and as he becomes recognized as a living legend for his bravery, he reestablishes his connection with Donna, now asking her to call him Finn. In this act of reclaiming his narrative, Finney moves forward, determined never to be overshadowed by fear again.
