We begin on a quiet street in a small town where a police officer discusses a gruesome discovery with his partner. Nearby, an ambulance is parked, and two EMTs struggle to load a stretcher carrying a covered body — a sight that horrifies onlookers due to its bloody condition. One officer remarks he’s never seen anything like it, noting the victim appears to have been torn apart. As the EMTs accidentally jostle the stretcher, entrails fall to the ground, further unsettling the crowd. Once the body is loaded, they drive off, leaving only a young boy on a bike, our protagonist, John Wayne Cleaver.
As the police vehicle moves away, John exits the road and is questioned by the officers about their grim findings. John’s nonchalant reply, “Well, he’s dead for sure,” sets the tone for his character. He rides through town to his home, which also functions as the local funeral home. Here, he assists his mother, April (portrayed by Laura Fraser), and his aunt, Margaret (played by Christina Baldwin), in their work. They mention the recently deceased man, and John, with characteristic dark humor, quips that at least they’ll profit from it, much to the dismay of the adults around him. As he prepares an elderly woman’s body, he jokes about the smell, only to be corrected by Aunt Margaret, showcasing his awkwardness in handling social situations.
In an introspective moment in his room, John grapples with questions of identity, seeming to practice social skills while reflecting on his true nature. Determined to investigate the crime scene, he discovers a strange black substance that heightens his curiosity. At school, he faces scrutiny from Principal Layton (played by James Gaulke) because of his report on the infamous BTK killer, Dennis Rader. The principal advises John about the fine line between curiosity about death and crossing into darker territory.
Seated in the cafeteria with his only friend Max (played by Raymond Brandstrom), John navigates interactions with their peers, facing bullying from Rob Anders (Vincent Russo), who mocks him, leading John to a disturbing confrontation in which he resists the urge to lash out. Instead, he inspects his sociopathic tendencies and attempts to articulate his thoughts on violence. A therapy session with Dr. Neblin (Karl Geary) reveals John’s self-awareness, although his fascination with the mechanics of death is unsettling for others.
Later, intrigued by a pretty girl named Brooke (played by Lucile Lawton), John’s stalking of the mysterious neighbor Mr. Crowley (Christopher Lloyd) mounts. John faces a complex relationship with his desires and his impulses, complicating his identity as he observes sinister happenings around town. Following the discovery of additional homicides, John’s relentless pursuit of knowledge leads to an obsession with profiling the killer.
Halloween brings unexpected tensions, as he encounters normal teenage life juxtaposed with his dark musings. The party scene becomes a battleground of social dynamics where John showcases his chilling honesty, confronting bullies in a manner that surprises and terrifies them. His hyper-awareness of his sociopathic inclinations becomes ever more pronounced.
As events unfold, John’s investigations lead him to link Mr. Crowley to the town’s growing body count. Tensions escalate when John unintentionally compels Crowley to expose his monstrous form during a climactic confrontation. John, caught between empathy and a survival instinct, faces a moral quandary over his mother’s life when Crowley threatens her, hinting at the depths of his attachment.
Ultimately, John realizes he can wield control over his destiny and possibly save those he loves by confronting Crowley, leading to a harrowing standoff that reveals the complex nature of humanity interwoven with monstrosity. In the end, John’s chilling journey culminates in a reflection of love, loss, and acceptance as he grapples with empathy and the consequences of human actions.
As the film closes, we see John continues to wrestle with his identity, aiming for a grasp on his emotions while preparing his therapist for burial. In a moment filled with dark humor, he remarks that consulting another therapist post-loss seems disloyal, leaving a poignant note as his family moves forward amid the complexities of life and death.
