After the death of his wife, Ben Howard returns to his childhood home in the small town of Falling Rock, Colorado. Along with his four-year-old daughter, he hopes to make a new life for his family, free from the painful memories that still haunt them both. But old memories die hard, as Ben soon discovers. Visions of his deceased wife follow him to Falling Rock—and that's just the beginning. Something strange is happening to the town. The temperature climbs even though winter is fast approaching. A stream of black smoke rises from the woods next to the old church—smoke, but no fire. The good people of Falling Rock disappear one by one. Something is hunting Ben's daughter; tormenting her from the shadows. An ancient evil lurks in the valley below the town—an evil that preys not just on the bodies of its victims, but on their sanity as well. As his world collapses around him, Ben must join with the few who remain to destroy a malevolent force that will not stop until it consumes every last human soul.
