The film chronicles the disturbed life of Jack, a serial killer possessing a peculiar artistic flair, unfolding over the span of twelve years. Jack's journey is marked by a series of chilling murders, each shaping his descent into darkness. Throughout this grim narrative, he engages in philosophical discussions with Verge, reflecting on ethics and his unique perspective of the world in between the gruesome incidents.
In the first incident, Jack, portrayed by Matt Dillon, encounters a woman experiencing car trouble, played by Uma Thurman. After some light-hearted banter, during which she jokingly suggests he might be a serial killer, Jack offers to help. When they arrive at a mechanic’s, the tire jack breaks, and after a brief return, Jack grimly uses it to kill her, storing her body in an industrial freezer he previously acquired. Concealing her car in the bushes near the state border keeps the police oblivious to his crime, as it's situated in a "no man's land."
The second incident finds Jack visiting another woman, portrayed by Siobhan Fallon Hogan, under the guise of a police officer who can assist her with her late husband’s pension. Once he gains her trust, he quickly turns violent, attempting to strangle her. When she regains consciousness, he sinisterly offers her water mixed with donuts in an effort to choke her, but when that fails, he resorts to strangling and stabbing her in a brutal act of desperation. His constant obsession with cleanliness nearly exposes him when a suspicious officer, played by Edward Speleers, comes to investigate. Yet again, luck favors Jack as rain washes away the blood trail he left behind.
In the third incident, Jack takes his date, a woman played by Sofie Grabol, along with her two sons, Grumpy and George, out for a hunting excursion. In a shocking turn of events, he kills the two boys from a distance using a sniper rifle before forcing their mother to serve pie to one of them. Ultimately, he kills her as well and grotesquely rearranges Grumpy’s face into a disturbing smile using his taxidermy skills.
The fourth incident introduces Jacqueline, portrayed by Riley Keough, whom Jack mistakenly believes to be naive. He brazenly confesses to her that he is the infamous serial killer, "Mr. Sophistication." Skeptical of his claims, she tries to escape after his disturbing advances. Jack, however, captures her and gruesomely murders her, even attaching her dismembered breast to a police car and crafting the other into a wallet.
In the fifth incident, Jack finds himself in a precarious position as he captures six victims, planning to execute them all with a single bullet. When he realizes his bullet isn’t suitable, he must seek help from a dealer named Al. A tense encounter ensues with a man named S.P., where Jack successfully convinces him to lower his weapon. After killing S.P., he dons his red bathrobe and awaits the police, who eventually arrive following Jack's reckless driving. In a last-ditch effort, he retrieves his necessary bullet, leading to a dramatic standoff with law enforcement.
In a clever twist, Jack's pursuit culminates in a makeshift house crafted from the remains of his victims, where he finds a mysterious hole. It is within this bizarre structure that he finally meets Verge, played by Bruno Ganz, who reveals Jack's unfinished business. As police forces begin to breach the door, Jack chooses to follow Verge down a darkened path.
In the epilogue, titled Katabasis, Jack discovers that Verge, akin to Dante’s guide Virgil, leads him through Hell. A broken bridge symbolizes the divide between Hell and a possible escape to Heaven. Despite Verge's warnings against climbing, Jack, driven by arrogance, attempts to navigate the treacherous cliff. His hubris leads to a tragic fall into the fiery abyss below.
Through these harrowing encounters, the film explores the chilling psychology behind Jack's character, his moral void, and the philosophical dialogues that create a haunting examination of a serial killer's mind.
