Bored Anita (Joanna Pacula) wants to escape small-town life but finds herself stuck in the middle of nowhere until her scientist husband finishes his research in a local swamp. Thus, Anita is understandably thrilled when brother and sister John and Janet Jones move to town and make life interesting; although John is a bit of a nutter, his sister is fun and lively, and she and Anita become fast friends. Unfortunately, things get weird and bodies start piling up, and Anita begins to suspect that maybe her new pal isn't who she claims to be. Paul Bartel and Annabelle Gurwitch co-star.
