Poor White Trash Part II (1974)

aka: Scum Of The Earth

Newlyweds Helen (Norma Moore) and Paul (Joel Colodner) go to a backwoods cabin on vacation. When Paul goes back to the car for some cigarettes he is struck by an axe. Panic-stricken, Helen runs into the woods, only to find Odie Pickett (Gene Ross) as her only savior. He takes her back to his place, where pregnant wife Emmy (Ann Stafford), son Bo (Charlie Dell), and daughter Sarah (Camilla Carr), do their best to give her a “family” welcome. While Helen's immediate danger is somewhat delayed, her newfound shelter begins showing some signs of danger as well.
