A routine prisoner transfer on a rural highway ends with the bus upside-down in a ravine, the driver dead of a heart attack, and convicted murderer Ernie Luntz on the loose, his eyes fixed on the mountain range in the distance, over which lies his hometown of Ash Falls. Set in a moss-draped, Pacific Northwest mountain town, Ash Falls is the story of a closely connected community both held together and torn apart by one man's single act of horrific violence. As the residents of Ash Falls - which include Ernie's ex-wife and teenage son wait on edge, wondering if and when Ernie Luntz will reappear, they come to discover that they are held prisoner not by the killer in the woods outside their town, but by the chains of their own creation.
