Mordum is a home movie shot by serial killers Peter Mountain, his sadomasochistic girlfriend Crusty and her depraved man-child brother, Maggot. After Peter walks in on Crusty and Maggot having sex, an argument erupts between them. It is quelled when Crusty sexually arouses Peter and herself via self-mutilation with a piece of glass. The two then break into a crack house, where Peter beats the owner to death with a hammer.
Crusty films the filth-encrusted building and the decaying corpse of an overdosed addict. When Peter starts stripping the body of the house's owner, claiming it will be easier to dispose of without clothes, another fight breaks out between him and Crusty when she questions his motive for undressing the body, accusing him of being "a faggot."
Crusty demonstrates her love of self-harm to Maggot and a friend, cutting her scarred arm with a knife. Crusty and Maggot remove a bound and masked woman from a box they have been keeping her in for "a long time." Maggot rapes the woman while Crusty cheers him on and taunts the victim. When Maggot is finished, he then lets a male captive out of another box, and he and Crusty force him to perform a penectomy on himself with a pair of cuticle scissors, then seal him back up. Crusty mimics oral sex with it, then uses it to violate the female victim.
The trio of killers go to town, where they torment a shopkeeper, eat fast food, and wander around. Maggot and Peter then watch and masturbate to Crusty torturing two women, sexually abusing and repeatedly vomiting on them while a male corpse rots in the corner of the room. Eventually, the women are killed. Maggot disembowels one, chewing on her spilled innards and masturbating with them, while the other is beaten to death by Crusty and Peter, the latter dragging the body away to presumably have sex with it. They get drunk, and afterward, Maggot is found in the bathroom by Crusty, shaving and cutting himself to "look beautiful" for her.
The trio are next shown playing in the snow, attending a concert, meeting up with friends, raping a woman, and going to a piercing shop, where Maggot receives a nose ring and gets into a fight with Peter over his relationship with Crusty. The group then visit another serial killer, who shows them the contents of his shed; mutilated bodies, dying victims, and a headless and maggot-covered toddler, which Maggot eats a chunk of. Later, while the others are asleep, the new killer borrows their camera, and films himself taunting and slitting the throat of one of his female captives.
The trio attacks a family, killing the father first by hanging him. While Peter tortures the mother, Crusty watches Maggot have sex with the corpse of the young daughter in a bathtub. The three get into a fight, which escalates to Peter slitting the throat of the wife, while abusing Maggot with her blood. Peter threatens to kill Maggot and takes a knife. Maggot snatches the knife from his hand and holds it to his own throat. The final shot of the scene looks like Maggot is cutting his own throat. Maggot apparently kills himself, and Crusty's scream can be heard in the background. This, and Maggot's absence from the next film, suggests that he had probably cut his throat and died. In the post-credits scene, a cat is shown eating a mouse.
