Jack, a disillusioned architect hailing from Washington State, opens up to Virgil, whom he affectionately calls Verge, as they embark on a harrowing journey through the nine circles of Hell. As they traverse this infernal landscape, Jack reflects on his transformation into a serial killer, with each of his grisly crimes unraveling through vivid flashbacks accompanied by Jack's own biting social commentary intermixed with insightful dialogues with Verge.
In his first act of violence, Jack encounters an assertive woman stranded on a remote road, struggling to fix her broken jack in order to replace a flat tire. Eager to assist, he offers to take her to a blacksmith, but their conversation quickly turns sour. The woman insults Jack, boldly stating that he resembles a serial killer and mocking him by claiming he lacks the resolve to actually commit murder. Fueled by anger and humiliation, Jack bludgeons her with the tire jack and hides her lifeless body in an industrial freezer located within a factory he had previously acquired from a pizzeria.
The storyline escalates in Jack's second crime, where he brutally murders a widow named Claire. However, his obsessive-compulsive tendencies propel him to obsessively return to the crime scene to clean it multiple times, which nearly puts him in the clutches of law enforcement. In a panicked rush, he ties Claire's body to the rear of his van, dragging it through the streets and leaving a bloody trail that leads back to his factory. Just as divine intervention seems to save him, rain washes away the evidence, prompting Jack to adopt the moniker "Mr. Sophistication," as he begins sending anonymous letters to the media under this name. With his OCD waning, he finds himself taking ever-greater risks.
The third incident is perhaps the most horrifying, as Jack takes his girlfriend and her two sons, referred to as "Grumpy" and George, on a seemingly innocent hunting trip. What follows is a shocking display of brutality as he methodically kills both boys and forces their mother to picnic amidst their corpses. Although he allows her a chance to flee, her fate intertwines with her children’s, as she chooses to confront Jack and meets her end at his hands. With gruesome creativity, Jack transforms Grumpy's lifeless body into a horrific sculpture sporting a grim grin.
In another chilling episode, Jack is entangled in a cruel relationship with a woman named Jacqueline, whom he emotionally and verbally torments, dubbing her "Simple." During a drunken admission of his murderous escapades, he boasts about having slain sixty individuals, yet Jacqueline is skeptical. After he menacingly marks her with red circles, she grows terrified enough to seek help from a police officer, who dismisses their drunken antics. Jack, however, continues his rampage, tying Jacqueline up and grotesquely mutilating her before pinning one of her severed breasts to the officer's vehicle, repurposing the other into a macabre wallet.
By the time of his fifth incident, the grim tally of Jack's victims mounts as he confines six men in his industrial freezer, plotting to eliminate them all with a single bullet. An unexpected complication arises when one of the men—a seasoned army veteran—points out that Jack is using the wrong ammunition. In an attempt to remedy his blunder, Jack ventures out to procure the correct bullets. However, fate intervenes when he stabs an accomplice named SP through the throat after SP calls the police due to Jack's notoriety. What follows is a bloodbath as he dispatches the responding officer, returning to his freezer for what he believes will be the climax of his gruesome tale. It is in this frozen chamber that he finally encounters Verge, who has silently observed Jack's murderous journey throughout his life. Verge reminds him of his long-neglected dream of building a home, a dream Jack seemed to have set aside while pursuing his dark passions. Ironically, within that very freezer, Jack assembles the frozen remains of his victims into what resembles a grotesque house.
As the police close in, Jack steps into his chilling "home" and is led by Verge into a gaping void in the floor, spiraling down into Hell itself. The two soon arrive at a pit marked by a bridge leading to the dreaded ninth circle—the core of Hell. During this unnerving descent, Jack is bombarded with eerie footage of the Kola Superdeep Borehole, where legends speak of human cries emanating from the depths of the Earth. Driven by an ill-fated desire to escape this hellish realm, Jack gazes at a stairway promising freedom from Hell, but against Verge’s caution, he recklessly attempts to scale the walls to reach it. The consequences of his hubris become dire as he plummets into the flaming abyss below, sealing his fate in an eternal nightmare.
