In 1978, Mary Hatchet comes of age amid a storm of fear and violence. After her first period triggers a terrifying outburst, she murders her parents with a hatchet. Deemed mentally unfit, she is confined to Kings Park Psychiatric Center, where the system treats her with cruelty and neglect. In 1989, she is raped and impregnated by a guard, a crime that is quickly covered up. Believing her child was a stillbirth, she endures another wound to her spirit and erupts in a brutal rampage through the hospital’s sterile corridors. The police confront her as she roams the grounds, and in a final act of horror, she hurls the severed head of her rapist at them, bringing an abrupt end to her killing spree. The grisly events fuse into a terrifying folklore, and locals begin to celebrate a Blood Night in her name, a mischievous echo of the horror that still lingers.
Decades later, in 2008, a group of teenagers set out for their own Blood Night by convening a séance at Mary Hatchet’s grave on Sweet Hollow Road in Huntington. The cemetery is guarded by the old King’s Park lore told to them by Gus, the caretaker who once worked at the asylum and who lingers in memory as a haunted witness to what happened there. Graveyard Gus insists that Mary’s spirit will keep coming back until she finds her child, a child said to lie buried near Kings Park. The teens return to a house party, where the night turns sinister as guests begin to disappear under the pressure of unseen forces and escalating supernatural phenomena. Panic spreads as bodies turn up, and the survivors flee into the night, their nerves frayed by the uncanny pressure of the haunting.
The remaining teens stumble back toward the truth with Gus by their side, and he leads them to the abandoned Kings Park Psychiatric Center to unearth the baby’s grave. The coffin is empty, and a pile of official papers reveals a chilling revelation: Mary’s child is Alissa, a missing party guest from Chicago. Through a series of flashbacks, it becomes clear that Alissa either acted under Mary’s influence or is already succumbing to a disorder echoing her mother’s legacy. Alissa returns in the present, and the terrifying hunt resumes as she kills Gus and pursues the others through the decayed halls of the asylum. The cat-and-mouse chase pushes to a brutal climax, with Alex and Lanie left scrambling for an exit. After a ferocious struggle, Alex winds up strangling Alissa to death, only to face a final, shocking turn as Mary’s enraged ghost decapitates him, turning the asylum into a chamber of echoes and doom and finally lurching toward the frightened Lanie.

In the quiet town of Sweet Hollow, the story of Mary Hatchet lingers like a whispered warning. Decades after the 1970s tragedy that forged her legend, locals mark the anniversary each year with a macabre rite known as Blood Night—a night when the line between folklore and reality feels dangerously thin. The atmosphere shivers with a blend of teenage bravado and an undercurrent of dread, as the community’s uneasy fascination with the past coalesces into a night that promises both thrill and an unsettling sense of déjà vu.
When a group of friends decides to stage their own Blood Night, they turn to the old cemetery on Sweet Hollow Road, where a weather‑worn grave holds the key to the legend. There they encounter Gus, the caretaker who once tended the doors of the infamous King’s Park Psychiatric Center. He shares fragmented memories of Mary’s story and hints that the spirit’s unrest may be tied to a hidden child, a chilling secret that fuels the teens’ curiosity and amplifies the night’s ominous charge.
Among the teenagers, Alex assumes the role of the pragmatic leader, trying to keep the group grounded as they delve deeper into the ritual. Lanie brings a more empathetic, almost psychic sensitivity to the gathering, sensing the weight of the past pressing on the present. The newcomer, Alissa, arrives with an enigmatic air that both intrigues and unsettles her companions, hinting at a personal connection to the old horror. Their dynamics crackle with youthful tension, each personality pushing against the other as unseen forces begin to stir.
The film’s tone is a slow‑burning blend of rustic Americana and oppressive gothic horror, set against the decaying backdrop of the abandoned asylum and its surrounding woods. As the night unfolds, the characters find themselves caught in a maze of history, superstition, and an atmosphere that feels alive with whispered threats, leaving the audience to wonder just how far the legend will reach into the present.
