The Cashen family has just relocated from the city to a farmhouse in the middle of nowhere in Texas. Upon arrival at their new home, Willy, their young son, explores the area, befriending a Native American shaman who warns him of the powerful forces and apparent curse on their land. Meanwhile, at home, Willy senses that there's something unusual about the cellar of their home; specifically that something strange might be living down there...and unfortunately for the Cashens, it's very hungry...
