What actually happens
A broken jack and an insult too many
Jack, a failed architect from Washington state, tells a man he calls Verge about some memorable incidents from his career as a serial killer. In the first, an abrasive woman needs her broken tire jack fixed so she can repair a flat tire. Jack drives her to a blacksmith, and she insults him the whole way. He takes offense, bludgeons her with the jack and stores her body in a freezer at a factory he bought from a pizzeria. Next comes Claire. After killing her, Jack's obsessive-compulsive disorder makes him clean the crime scene so thoroughly that he nearly gets caught. He panics and drives away without securing her body, dragging her behind his van and leaving a blood trail to the factory. Rain washes the trail away, and Jack decides this is divine intervention. He then promises to take greater risks, writing to the media anonymously and taunting the police.
Reading this instead of watching it is the correct decision. Scaredy Cat makes that decision automatic, for free.
A hunting trip with a girlfriend and her sons
This is the scene people dread most, and it comes in the middle of Jack's stories. Jack tells Verge about a hunting trip he took with his girlfriend, and Grumpy and George, her two sons, came along. He kills both boys, torments their mother, and then kills her as well. Afterward he turns Grumpy's body into a sculpture with a grisly smile. All three of them die, the two boys first and their mother last.
A red wire and a wallet
Jack has a toxic relationship with a woman named Jacqueline, and he abuses her. They talk on phones joined by a red wire, which nods to the Chinese idea of a red thread tying lovers together. One drunken night Jack confesses his killings to her, and she goes to a policeman, who brushes her off as drunk. Jack later ties her up and cuts off her breasts. One of them he pins to the policeman's car and makes the other into a wallet.
The wrong ammunition, and then a house made of people
Jack wants to shoot six men in his freezer using only one bullet. An army veteran among them tells him he needs the right ammunition, so Jack goes to a gun store and angrily berates the owner, Al, for selling him the wrong kind. As Jack leaves, Al uses the phone, probably to warn SP. Jack visits his contact SP to buy ammunition. SP calls the police, so Jack kills him and the officer who responds. Back at the freezer, Jack unseals a chamber and meets Verge, who has been watching Jack throughout his life. Jack stacks all the frozen bodies he has gathered over the years so that they form the outline of a house. As the police break in, Jack steps into his house and follows Verge through a hole in the floor into Hell.
The ending, explained
In Hell, Jack and Verge reach a pit that leads to the ninth circle, the center of Hell. Footage plays of the Kola Superdeep Borehole, where, as the story goes, people heard cries coming up from the underworld. A broken bridge crosses the pit, and on the far side is a staircase that leads out of Hell. Jack ignores Verge's advice and tries to climb a rock wall to reach it. He falls straight into Treachery, which is his final punishment, and Verge slowly walks away.
