The year is 2019. War has erupted between the western rebel states and the United States federal government. Fighting in Denver has made life for all dogs - strays and pets alike - almost impossible. In order to survive, many have fled along the highways until they have found themselves here, in Breckenridge. This isolated mountain town seems to be the best place to wait out the fighting, even though military transports and human scavengers regularly pass through. It is in this desperate refuge where dogs must learn to survive war, or lose their lives in the fighting.
