A happily married father of two, shaken by a message written in a birthday card for his daughter, abruptly leaves his family for a week-long hike through the Grand Canyon. Following his solo trek, we see his memories of an earlier trip through the Grand Canyon with a different woman.
When the Haskin family seeks refuge from Y2K hysteria in the isolated forests of the Sierra Diablos mountains, madness and terror find them there. Abducted by a vicious hillbilly clan, the Haskins fight for survival, but neither they nor the hillbilly Crawfords can comprehend the monstrous nightmare about to erupt from the bowels of the earth.
