Vincent Smith (Rory Calhoun) and his sister Ida (Nancy Parsons) run a rural hotel, but they earn most of their cash operating a food stand that specializes in world-famous sausages. After years of success, however, the duo's upstanding brother, Sheriff Bruce (Paul Linke), eventually discovers the grotesque details of his siblings' booming business: Vincent and Ida are actually plumping up their hotel patrons, killing and dismembering them and then grinding them into frankfurters.
