A grieving family contends with a growing sense of dread after moving to the desert and experiencing a series of tragic, inexplicable accidents. When Robert Coltrane died suddenly, the life his family once knew was forever changed. In an effort to regain some sense of normalcy, his widow Helen (Melora Walters) takes their teenage children Conrad (Jackson Rathbone) and Lenore (Johanna E. Braddy) to live with their reclusive uncle Darryl (William Mapother) in Arizona. But life around William's house is far from normal; not only is the seldom seen uncle something of a gun fanatic, but just as the family is settling in they receive a most unusual visitor. It seems that before Robert died, he agreed to take in Sarah (Sofia Vassilieva), a lovely yet troubled young girl from a particularly unstable background. Shortly after Sarah's arrival, the Coltrane's are plagued by a series of macabre occurrences that seem to have no reasonable explanation.
