Horror sequel continuing the story of a group of ill-fated cavers. After Sarah Carter (Shauna MacDonald) is rescued from the Appalachian caves where several of her friends came to a bloody end, she is made to go back and help to try and find any remaining survivors. The local Sheriff (Gavan O'Herlihy) is not wholly convinced by Sarah's version of events or about what she claims she and her friends encountered in the caves and so pushes for the rescue expedition. It soon becomes clear, however, that every awful thing Sarah told him was true.
