Courtney (Shannyn Sossamon) and her twin boys, Zach and Dylan, have moved into a seemingly idyllic and secluded old house in an attempt to evade Courtney's estranged husband Clint (Lea Coco). Unbeknownst to her, the house holds secrets of a gruesome ritualistic massacre and is marked for death. When Ex-Deputy So & So (James Ransone) investigates, he uncovers an ancient myth that means the killer might be someone - or something - more evil than anything ever imagined.
