Lester Bacon is an old nut-case farmer living with his simple-minded, obese son Buddy. Both of them lament the fate of the old skilled hog farmer, now giving way to modern factory-type slaughterhouses. The father and son go on a killing spree against people who trespass on their property. In the opening scene, Buddy kills two teenagers, Kevin and Michelle, who are having some time alone in their car on a remote area of Lovers Lane.
