Billy is shown running a severed pig's head and hoofs up and down the body of a sex worker, in a strangely sexual sequence, as the detective narrates.
His first victim, Cara, is drowned in a bathtub, placed in a large wheeled trash can, taken to the family pig farm, and fed into a wood chipper.
Throughout the film, the detective implies and then finally accuses Billy of mixing the remains of the victims with pork meat that was then sold to a national food market chain for public consumption.
In flashback dinner scenes with his sister Julia and brother Darryl, Billy does not answer questions about why the pork products "taste so good".
After the next victim, Wendy, is strangled and buried alive, Billy is interrupted by three teenage hitchhikers, one of whom he treats for a spider bite before sending them on their way, unharmed.
Billy narrates how his mother made an audio recording of his father's death, which forever colored his view of women as "evil whores".
