Jessica (Anwar) and husband William (Cusick) have fled the city amid ever-increasing terrorist threats. William is excited to relocate to his newly purchased ranch hundreds of miles from nowhere. Jessica reluctantly humors her husband and his paranoid fears by going along. On their arrival, William and Jessica discover someone already living in their house. Elias (Ortiz) proves quite an intimidating presence when the couple discovers him in their kitchen butchering a freshly killed animal. But Elias soon explains in his broken English that he was the caretaker for the previous owner who had promised to let him continue living there as a reward for his services. William knows of no such arrangement and quickly attempts to get rid of this man he sees as nothing more than a trespasser. Elias sees the couple the same way and develops his own ideas about sending them back to the city. Just as the property dispute escalates to a dangerous level, the three hear parts of an emergency radio broadcast indicating that an extremely large terrorist attack has caused widespread, catastrophic destruction in the world around them. The three are cut off from everything, completely in the dark as to whether anybody at all, is left alive in the area, the country or even the world. Civilization as they have come to know it may have ended.
