The Night They Returned.

Confined to a cell in a mental asylum, young Jessica has a tale to tell, if the doctors will listen. Her sexy sisters Brenda and Tawny would frequently tie her up in her bedroom for her own safety, they claimed. Maybe, but more likely to prevent her from interfering in their favorite pastime. Seems the two sisters have a habit of seducing hapless males into returning to their secluded backwoods cabin, only to be trussed up, brutally butchered and snacked on! But dad's in the house, why won't he do something about these ghoulish shenanigans? Oh, that's right. He's dead!
