Slaughterhouse (1987)

You'll never get out in one piece.

The owner of a once prosperous hog slaughtering plant and his obese, simple-minded son Buddy still reside on the dilapidated property. Though it is to be auctioned off by the county to pay back taxes, the old man is determined to stay with his son, living among a few pet hogs and the motionless rusted hooks.
