A car speeds along a rain-soaked road at night, while a woman named Laura sits in a café, sipping her coffee. Suddenly, two men enter the restaurant and take a seat nearby, their gaze fixed on her. Alarmed, Laura abruptly leaves, revealing her pregnancy. The men pursue her, leading to a distressing scene where Laura is in labor, declaring, > "I don't want you, I don't want you."
Fast forward eight years, and Laura lives a simple yet joyful life with her son David. Her neighbor, Susan, lends a helping hand by watching David as Laura manages her responsibilities. But one fateful night, a disturbance awakens Laura as she hears unsettling noises from David's room. Rushing over, she finds a group of figures surrounding her child. Desperate for help, she alerts Susan to call the police. Upon her return, Laura discovers that the mysterious figures have vanished, leaving David peacefully asleep, albeit with no recollection of the incident, except for a vivid dream of drowning in blood.
When local detectives, Paul and Steve, investigate, Steve dismisses Laura's claims as mere fabrications, attributing the event to sleepwalking or nightmares. However, Paul, showing more empathy, vows to follow up on Laura's troubling report. Later, her fears intensify when David mysteriously becomes ill, with no clear diagnosis from the doctors, adding to her paranoia that the individuals in David's room may have poisoned him.
Laura's frantic worries seem validated when David inexplicably recovers later, only to fall sick again, leading her to confide in Paul about her traumatic past in a cult, suggesting that they are the ones tormenting David. That night, overhearing disturbing conversations from the doctors, Laura's panic escalates as she spots suspicious figures lurking outside the hospital. Without a second thought, she absconds with David and seeks refuge with [Susan], only to find her neighbor deceased and David disconcertingly consuming parts of her body.
In a frenzied state, Laura scrawls "He Is Coming" across the wall in Susan's blood, a chilling chant from her past. She escapes with David, leading them to a motel, where they unexpectedly see themselves on the news. Switching cars and fleeing from the spotlight, Laura hunts for an old friend, hoping to regain suppressed memories. Paul and Steve, meanwhile, uncover Laura's harrowing history of abuse and the presumed fable of the cult she claims haunted her life.
As Laura reconnects with Jimmy, her former cult companion, she learns about the horrific traditions they endured, including grisly animal sacrifices and a dark ritual intended to summon a demonic entity. The stakes rise as David's behavior grows more erratic, leaving Laura in a constant state of alarm. During a moment of desperation, she engages a pimp to alleviate their situation, with shocking consequences as David savagely attacks him.
While Paul and Steve piece together the severity of Laura's past, Laura and David share fleeting moments of joy, but her son’s health rapidly deteriorates. A wrongful shooting incident involving local law enforcement hints at the chaos engulfing their lives. Facing the haunting memories of their past, Laura drives David back to the house of her upbringing, where disillusionment awaits.
In a climactic turn, Laura recalls an ancient chant and attempts to summon the entity from her past, hoping to save David—her son whom she believes she must protect at all costs. Just as a shadowy figure materializes, the police intervene, leading to a heartfelt confrontation between Laura and Paul, who tries to convince her of her delusions. In a tragic moment of desperation, Paul sees through to Laura's intentions to save David, and the narrative spirals into a terrifying conclusion where the true nature of dark legacies and loyalties blurs the lines of reality and madness.
In an unexpected twist, it's revealed that the cult's grip is not just in Laura's mind; Paul hides sinister secrets of his own that connect them all. The narrative weaves a complex tapestry of trauma, sacrifice, and twisted love, as the story culminates in a chilling alliance between David and the entity that emerges from the shadowy depths of his mother’s haunted past.
