Undetected

A strange ghost town is the last hope for two sisters who are stranded on a remote stretch of road. Desperate for food and water, the girls find, to their horror that the lone occupants are a couple of zombie-like hillbillies, Earl and Betty. Earl greets them with a flesh-eating grin. The girls ask for a phone and Betty leads them into a moth-laden kitchen and a phone with no dial tone. They ask for another way to communicate and the zombies mail a letter. The girls are unsure if the zombies are simply reclusive inbreeds in need of a good bath or if they're dangerous. The girls have no choice but to stay and find out.
