What year did Mary Lou Maloney die?
In a chilling turn of events, Mary Lou Maloney, the once-prominent prom queen who met her fate in a fiery explosion in 1957, manages to escape the depths of hell using her wits and a nail file. Her vengeful spirit returns to Hamilton High School, a place where she once caused turmoil, and she begins her quest for revenge on those she believes deserve punishment.
The day after Mary Lou’s return, Principal Weatherall kicks off the opening of the newly renovated gymnasium with a ceremonial ribbon-cutting. However, a bizarre incident leads to chaos as an unseen force is unleashed, sending powerful gusts of wind whirling through the school halls.
Amidst this turmoil, Alexander Grey, a fairly average student with dreams of enrolling in medical school, finds himself struggling academically. His lack of motivation has led guidance counselor Ms. Richards to deliver a stern warning—without immediate improvement, a life of menial jobs awaits him.
As Alex tries to navigate the trials of high school life, Mary Lou’s presence becomes palpable, starting with a seduction so graphic it occurs on the American flag itself, symbolizing her dominance over the living. With her influence, Alex sees a turnaround—his grades improve drastically, leading him to the honor roll and even football stardom, which deeply frustrates his rival, Andrew Douglas.
While this newfound success is intoxicating, it comes with significant drawbacks. His secret relationship with Mary Lou strains his connection with his girlfriend, Sarah Monroe. As the story progresses, the consequences of their dark bond become evident, leading to the troubling demise of Ms. Richards via a horrifying battery acid fate.
As the body count rises, Alexander begins to grasp the true nature of Mary Lou’s influence: it’s not just beneficial, but increasingly destructive and possessive. Torn between his desire to break free from her grip and the ecstasy of their toxic relationship, he navigates a treacherous emotional landscape.
The conflicts reach a breaking point when Andrew Douglas confronts Alex, igniting a violent altercation that results in a tragic death, with Mary Lou mercilessly impaling Andrew with a football that morphs into a spinning drill—a chilling twist of fate.
As tensions escalate, Alex attempts to reconnect with Sarah by inviting her to the prom at the school’s newly opened gym. However, he receives a heartbreaking rejection: she is already going with Leonard Welsh, an awkward yet good-natured fellow. In a devastating turn of events, Mary Lou’s jealousy manifests, leading to the tragic loss of Alex’s best friend, Shane Taylor, at her hands. When authorities wrongfully blame Alex for Shane’s death, he finds himself imprisoned and desperate to prove his innocence.
Meanwhile, Mary Lou’s dark presence continues to wreak havoc even from behind bars. In a haunting encounter in Alex’s cell, she offers him a sinister proposal: if he agrees to join her in Hell, she’ll spare the lives of his loved ones. Faced with a heart-wrenching choice, he decides to join Mary Lou in the underworld to protect those he cherishes.
As the prom festivities unfold, Sarah becomes targeted by Mary Lou, who has brutally dispatched Leonard using magnetic tape. With Officer Larry held hostage, Alex takes control of a vehicle and races toward the gym, hoping to intervene before it’s too late. In a climactic sequence, Alex and Mary Lou plunge into the depths of Hell, with Sarah leaping after them in a desperate attempt to rescue him.
In this grim realm, Sarah embarks on a perilous mission to save her beloved Alex from Mary Lou’s demonic hold. Armed with a makeshift flamethrower, she battles zombified versions of Shane and Leonard before locating Alex in Hell’s eerily familiar gym. There, she interrupts Mary Lou’s grim plans to crown Alex as her eternal prom king, leading to an explosive confrontation that results in Mary Lou’s destruction at Sarah’s hands.
With the dust settling from this chaotic showdown, Alex and Sarah manage to escape in a vehicle from a garage within the school. But as they drive away, they come face-to-face with the charred remains of Mary Lou, which Alex dispatches with cold determination. Having freed themselves from the underworld, they find themselves back on a deserted street, forever altered by their harrowing experiences.
In what they hope will be a quiet moment, they head to a diner to reconnect with friends and family. But their brief respite shatters when Mary Lou reappears, plunging her arm deep into Sarah’s body with horrifying force. As Sarah’s life slips away, Alex realizes he is trapped in a strange temporal loop, reliving the 1950s while desperately trying to break free. The world around him is stuck in an outdated era, with oblivious individuals ignoring his frantic cries for help. As despair envelops him, Mary Lou’s relentless malevolence closes in, leaving him vulnerable and overwhelmed with sorrow.
